Full textAbstract:
This study supports the need for information literacy training for first year or new incoming Community and Health Science (CHS) students at the University of the Western Cape (UWC) and describes the use of a collaborative framework for integrating information literacy into the undergraduate studentsʹ curriculum and for assessing the results. The Collaborative Information Literacy Model (CILM) provided the guidelines for a more structured and fuller collaboration between the librarian and the lecturer responsible for the first year Physiotherapy students. The collaborative partnership employed strategies to teach information literacy competencies which were significantly more satisfactory with the studentsʹ abilities to successfully complete a research term paper. The process of integration began with developing learning outcomes, an information literacy program, exercises and an assessment instrument for evaluating student performance. Also emphasized is the on-going exchange of expertise between the librarian and the lecturer to enhance library-related components in the design of the program.

Full textAbstract:
Although educational content in electronic form is increasing dramatically, its usage in an educational environment is poor, mainly due to the fact that there is too much of (unreliable) redundant, and not relevant information. Finding appropriate answers is a rather difficult task being reliant on the user filtering of the pertinent information from the noise. Turning knowledge bases like the online tele-TASK archive into useful educational resources requires identifying correct, reliable, and "machine-understandable" information, as well as developing simple but efficient search tools with the ability to reason over this information.
Our vision is to create an E-Librarian Service, which is able to retrieve multimedia resources from a knowledge base in a more efficient way than by browsing through an index, or by using a simple keyword search. In our E-Librarian Service, the user can enter his question in a very simple and human way; in natural language (NL). Our premise is that more pertinent results would be retrieved if the search engine understood the sense of the user's query. The returned results are then logical consequences of an inference rather than of keyword matchings. Our E-Librarian Service does not return the answer to the user's question, but it retrieves the most pertinent document(s), in which the user finds the answer to his/her question.
Among all the documents that have some common information with the user query, our E-Librarian Service identifies the most pertinent match(es), keeping in mind that the user expects an exhaustive answer while preferring a concise answer with only little or no information overhead. Also, our E-Librarian Service always proposes a solution to the user, even if the system concludes that there is no exhaustive answer.
Our E-Librarian Service was implemented prototypically in three different educational tools. A first prototype is CHESt (Computer History Expert System); it has a knowledge base with 300 multimedia clips that cover the main events in computer history. A second prototype is MatES (Mathematics Expert System); it has a knowledge base with 115 clips that cover the topic of fractions in mathematics for secondary school w.r.t. the official school programme. All clips were recorded mainly by pupils. The third and most advanced prototype is the "Lecture Butler's E-Librarain Service"; it has a Web service interface to respect a service oriented architecture (SOA), and was developed in the context of the Web-University project at the Hasso-Plattner-Institute (HPI).
Two major experiments in an educational environment - at the Lycée Technique Esch/Alzette in Luxembourg - were made to test the pertinence and reliability of our E-Librarian Service as a complement to traditional courses. The first experiment (in 2005) was made with CHESt in different classes, and covered a single lesson. The second experiment (in 2006) covered a period of 6 weeks of intensive use of MatES in one class. There was no classical mathematics lesson where the teacher gave explanations, but the students had to learn in an autonomous and exploratory way. They had to ask questions to the E-Librarian Service just the way they would if there was a human teacher.Obwohl sich die Verfügbarkeit von pädagogischen Inhalten in elektronischer Form stetig erhöht, ist deren Nutzen in einem schulischen Umfeld recht gering. Die Hauptursache dessen ist, dass es zu viele unzuverlässige, redundante und nicht relevante Informationen gibt. Das Finden von passenden Lernobjekten ist eine schwierige Aufgabe, die vom benutzerbasierten Filtern der passenden Informationen abhängig ist. Damit Wissensbanken wie das online Tele-TASK Archiv zu nützlichen, pädagogischen Ressourcen werden, müssen Lernobjekte korrekt, zuverlässig und in maschinenverständlicher Form identifiziert werden, sowie effiziente Suchwerkzeuge entwickelt werden. Unser Ziel ist es, einen E-Bibliothekar-Dienst zu schaffen, der multimediale Ressourcen in einer Wissensbank auf effizientere Art und Weise findet als mittels Navigieren durch ein Inhaltsverzeichnis oder mithilfe einer einfachen Stichwortsuche. Unsere Prämisse ist, dass passendere Ergebnisse gefunden werden könnten, wenn die semantische Suchmaschine den Sinn der Benutzeranfrage verstehen würde. In diesem Fall wären die gelieferten Antworten logische Konsequenzen einer Inferenz und nicht die einer Schlüsselwortsuche. Tests haben gezeigt, dass unser E-Bibliothekar-Dienst unter allen Dokumenten in einer gegebenen Wissensbank diejenigen findet, die semantisch am besten zur Anfrage des Benutzers passen. Dabei gilt, dass der Benutzer eine vollständige und präzise Antwort erwartet, die keine oder nur wenige Zusatzinformationen enthält. Außerdem ist unser System in der Lage, dem Benutzer die Qualität und Pertinenz der gelieferten Antworten zu quantifizieren und zu veranschaulichen. Schlussendlich liefert unser E-Bibliothekar-Dienst dem Benutzer immer eine Antwort, selbst wenn das System feststellt, dass es keine vollständige Antwort auf die Frage gibt. Unser E-Bibliothekar-Dienst ermöglicht es dem Benutzer, seine Fragen in einer sehr einfachen und menschlichen Art und Weise auszudrücken, nämlich in natürlicher Sprache. Linguistische Informationen und ein gegebener Kontext in Form einer Ontologie werden für die semantische Übersetzung der Benutzereingabe in eine logische Form benutzt. Unser E-Bibliothekar-Dienst wurde prototypisch in drei unterschiedliche pädagogische Werkzeuge umgesetzt. In zwei Experimenten wurde in einem pädagogischen Umfeld die Angemessenheit und die Zuverlässigkeit dieser Werkzeuge als Komplement zum klassischen Unterricht geprüft. Die Hauptergebnisse sind folgende: Erstens wurde festgestellt, dass Schüler generell akzeptieren, ganze Fragen einzugeben - anstelle von Stichwörtern - wenn dies ihnen hilft, bessere Suchresultate zu erhalten. Zweitens, das wichtigste Resultat aus den Experimenten ist die Erkenntnis, dass Schuleresultate verbessert werden können, wenn Schüler unseren E-Bibliothekar-Dienst verwenden. Wir haben eine generelle Verbesserung von 5% der Schulresultate gemessen. 50% der Schüler haben ihre Schulnoten verbessert, 41% von ihnen sogar maßgeblich. Einer der Hauptgründe für diese positiven Resultate ist, dass die Schüler motivierter waren und folglich bereit waren, mehr Einsatz und Fleiß in das Lernen und in das Erwerben von neuem Wissen zu investieren.

Full textAbstract:
An ACRL white paper from 2012 reported that, at that time, only a small number of academic libraries in the United States and Canada offered research data services (RDS), but many were planning to do so within the next two years (Tenopir, Birch, and Allard, 2012). By 2013, 74% of the Association of Research Libraries (ARL) survey respondents offered RDS and an additional 23% were planning to do so (Fearon, Gunia, Pralle, Lake, and Sallans, 2013). The academic libraries recognize that the landscape of services changes quickly and that they need to support the changing needs of research and instruction.
In their efforts to implement RDS, libraries often respond to pressures originating outside the library, such as national or funder mandates for data management planning and data sharing. To provide effective support for researchers and instructors, though, libraries must be proactive and develop new services that look forward and yet accommodate the existing human, technological, and intellectual capital accumulated over the decades. Setting the stage for data curation in libraries means to create visionary approaches that supersede institutional differences while still accommodating diversity in implementation. How do academic libraries work towards that?
This chapter will combine an historical overview of RDS thinking and implementations based on the existing literature with an empirical analysis of ARL libraries’ current RDS goals and activities. The latter is based on the study we conducted in 2015 that included a content analysis of North American research library web pages and interviews of library leaders and administrators of ARL libraries. Using historical and our own data, we will synthesize the current state of RDS implementation across ARL libraries. Further, we will examine the models of research data management maturity (see, for example, Qin, Crowston and Flynn, 2014) and discuss how such models compare to our own three-level classification of services and activities offered at libraries - basic, intermediate, and advanced. Our analysis will conclude with a set of recommendations for next steps, i.e., actions and resources that a library might consider to expand their RDS to the next maturity level.

Bock, Matthew. "A Framework for Hadoop Based Digital Libraries of Tweets." Thesis, Virginia Tech, 2017. http://hdl.handle.net/10919/78351.
Full textAbstract:
The Digital Library Research Laboratory (DLRL) has collected over 1.5 billion tweets
for the Integrated Digital Event Archiving and Library (IDEAL) and Global Event
Trend Archive Research (GETAR) projects. Researchers across varying disciplines
have an interest in leveraging DLRL's collections of tweets for their own analyses.
However, due to the steep learning curve involved with the required tools (Spark,
Scala, HBase, etc.), simply converting the Twitter data into a workable format can
be a cumbersome task in itself. This prompted the effort to build a framework that
will help in developing code to analyze the Twitter data, run on arbitrary tweet
collections, and enable developers to leverage projects designed with this general
use in mind. The intent of this thesis work is to create an extensible framework of
tools and data structures to represent Twitter data at a higher level and eliminate the
need to work with raw text, so as to make the development of new analytics tools
faster, easier, and more efficient.
To represent this data, several data structures were designed to operate on top of
the Hadoop and Spark libraries of tools. The first set of data structures is an abstract
representation of a tweet at a basic level, as well as several concrete implementations
which represent varying levels of detail to correspond with common sources
of tweet data. The second major data structure is a collection structure designed to
represent collections of tweet data structures and provide ways to filter, clean, and
process the collections. All of these data structures went through an iterative design
process based on the needs of the developers.
The effectiveness of this effort was demonstrated in four distinct case studies. In
the first case study, the framework was used to build a new tool that selects Twitter
data from DLRL's archive of tweets, cleans those tweets, and performs sentiment
analysis within the topics of a collection's topic model. The second case study applies
the provided tools for the purpose of sociolinguistic studies. The third case
study explores large datasets to accumulate all possible analyses on the datasets.
The fourth case study builds metadata by expanding the shortened URLs contained
in the tweets and storing them as metadata about the collections. The framework
proved to be useful and cut development time for all four of the case studies.Master of Science

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROEste trabalho objetiva o desenvolvimento de Bibliotecas Digitais de Learning Objects (LO-DLs), usando técnicas de Data Warehousing (DWing) e Data Mining (DMing). Através da abordagem de Data Warehousing pode-se correlacionar os passos principais desta técnica, que são Extração, Transformação, Carga e OLAP, com os principais serviços de Bibliotecas Tradicionais, que são Aquisição, Classificação por Assunto, Catalogação e Consulta/Análise, de forma que eles sejam processados automaticamente. Técnicas de Data Mining são incorporadas a alguns desses processos automatizando o desenvolvimento da biblioteca. Além de integrar múltiplas fontes de LOs, que estão armazenadas em diferentes SGBDs (Sistemas de Gerência de Banco de Dados) e catalogadas através de diferentes padrões de metadados, esta abordagem contribui para prover o usuário de uma maneira mais sofisticada de consulta ao acervo, mais abrangente que as usuais opções por título, autor e assunto, já que OLAP propicia acesso multidiimensional. Além disso, também contribui para melhorar a qualidade da biblioteca, uma vez que as técnicas OLAP e de Data Mining são usadas para analisar os LOs e os acessos aos mesmos. Uma atualização automática da biblioteca acontece quando há mudança no perfil do usuário.
This work aims at the development of Learning Objects Digital Libraries (LO-DLs), using Data Warehousing (DWing) and Data Mining (DMining) techniques. By using the Data Warehousing approach, we will be able to correlate the main steps of this technique, which area Extraction, Transformation, Loading and OLAP, with the main services of a Traditional Library which are Acquisition, Subject Classification, Cataloging, and Searching, so that they will work in an automatic way. Data Mining techniques are incorporated in some of these processes automating the process of the development of the library. Besides integrating multiple LOs sources, which are stored in diverse DBMSs (Data Base Management Systems) and catalogued in different metadata languages, this approach contributes to providing the user with a sophisticated query to the library that is more comprehensive than the usual author, subject or title options, since OLAP allows multidimensional access. Furthermore it also contributes to the improvement of the library, since OLAP and data mining techniques are used to analyze LOs data and the access to them. An automatic refresh of the library is made when users´ profile changes.

Full textAbstract:
The biological datasets produced as a result of high-throughput genomic research such as specifically microarrays, contain vast amounts of knowledge for entire genome and their expression affiliations. Gene clustering from such data is a challenging task due to the huge data size and high complexity of the algorithms as well as the visualization needs. Most of the existing analysis methods for genome-wide gene expression profiles are sequential programs using greedy algorithms and require subjective human decision. Recently, Zhu et al. proposed a parallel Random matrix theory (RMT) based approach for generating transcriptional networks, which is much more resistant to high level of noise in the data [9] without human intervention. Nowadays GPUs are designed to be used more efficiently for general purpose computing [1] and are vastly superior to CPUs [6] in terms of threading performance. Our kernel functions running on GPU utilizes the functions from both the libraries of Compute Unified Basic Linear Algebra Subroutines (CUBLAS) and Compute Unified Linear Algebra (CULA) which implements the Linear Algebra Package (LAPACK). Our experiment results show that GPU program can achieve an average speed-up of 2~3 times for some simulated datasets.

Full textAbstract:
Research data management (RDM) focuses on the organization and description of data, from
its entry to the research cycle through to the dissemination and archiving of valuable results.
RDM entails storage, security, preservation, compliance, quality, sharing and jurisdiction. In the
academic world, RDM can support the research process by searching for relevant data, storing
data, describing data and advising researchers on good RDM practice.
This study focused on developing RDM services. The aim of the study was to establish the role
Makerere University Library could play in developing RDM Services. A number of questions
were formulated to guide the researcher in finding answers to the research questions.
A literature review, based on the research sub-questions, was carried out. The review covered
the concept of RDM, academic libraries and their RDM practices, various RDM services in
academic libraries, RDM services that require sustainability and how current researchers, in
general, manage their data.
The research undertaken took a qualitative approach with a case study design. This was due to
the need to gather in-depth and comprehensive views and experiences regarding RDM at
Makerere University. A purposive sampling technique was used to identify researchers who are
actively involved in managing research data at Makerere University. Data were collected using
semi structured interviews, from eight participants; one from each college. The participants were
selected because of their knowledge about RDM and semi-structured interviews were preferred
due to their flexibility. An interview schedule was used as the data collection instrument. Data
was transcribed into Microsoft Word for easy analysis.
Findings that addressed the research question and sub-questions were presented and
interpreted in chapter four and conclusions as well as recommendations were discussed in
detail in chapter five of this research report. In summary it is possible to say that although
researchers, from across the entire university, generate big volumes of research data it appears
that researchers themselves manage, control and store their data making use of different
removable devices. This is risky. So there is a need to develop RDM skills for all stakeholders. It
does appear though that the researchers at Makerere University would be willing the support of
RDM services if these are developed by the library.Mini Dissertation (MIT)--University of Pretoria, 2017.

Artificial Intelligence Lab, Department of MIS, University of ArizonaThis research examined the applicability of using a neural network approach to analyze population pharmacokinetic data. Such data were collected retrospectively from pediatric patients who had received tobramycin for the treatment of bacterial infection. The information collected included patient-related demographic variables (age, weight, gender, and other underlying illness), the individualâ s dosing regimens (dose and dosing interval), time of blood drawn, and the resulting tobramycin concentration. Neural networks were trained with this information to capture the relationships between the plasma tobramycin levels and the following factors: patient-related demographic factors, dosing regimens, and time of blood drawn. The data were also analyzed using a standard population pharmacokinetic modeling program, NONMEM. The observed vs predicted concentration relationships obtained from the neural network approach were similar to those from NONMEM. The residuals of the predictions from neural network analyses showed a positive correlation with that from NONMEM. Average absolute errors were 33.9 and 37.3% for neural networks and 39.9% for NONMEM. Average prediction errors were found to be 2.59 and -5.01% for neural networks and 17.7% for NONMEM. We concluded that neural networks were capable of capturing the relationships between plasma drug levels and patient-related prognostic factors from routinely collected sparse withinpatient pharmacokinetic data. Neural networks can therefore be considered to have potential to become a useful analytical tool for population pharmacokinetic data analysis.

Full textAbstract:
The primary purpose of this study was to test the following hypothesis: The internal use (use within the technical services unit for decision making and planning) of statistical data will be significantly higher for managers scoring in the Sensing-Thinking (ST) scale of the self-assessment instrument Myers-Briggs Type Indicator. A Technical Services Statistics Survey Form was developed in order to collect statistical data from the technical services managers participating in the study. The Myers-Briggs Type Indicator was utilized to record managers' personal management style. Thirty-two managers participated in the two-part study. The hypothesis of the study was not supported because no significant differences in the predicted direction were found to exist between the use of the technical services statistics and management style groups as measured by the Myers-Briggs Type Indicator. (A Mann-Whitney U Test was used due to the small, uneven sample size.) There were significant differences between Sensing-Thinking (ST) and Intuitive-Feeling (NF) types, but not in the direction predicted by the hypothesis. Possible explanations for this unexpected finding include the very small sample size, the larger percentage of male respondents in the NF type, and the larger percentage of respondents from smaller institutions in the NF type. (Gender and institutional size were not analyzed in this study.) A sharp contrast existed in the number and guality of comments provided by Sensing-Thinking (ST) and Intuitive-Thinking (NT) types, both of whom tended to write lengthy detailed comments elaborating on each statistic. Sensing-Feeling (SF) and Intuitive-Feeling (NF) types provided little or no comment on the Technical Services Statistics Form. The results of this research have implications for examining the technical services statistics collected in technical services units: the frequency of analysis; their importance for planning; the use of these statistics; and the level at which the statistic is used for decision making. Other implications pertain to the automation of statistical data and the use or non-use of the automated reports available.

Full textAbstract:
Information systems used in archaeological research have several needs that can be summarized as follows: interoperability among diverse, heterogeneous systems, making information available without significant delay, providing a sustainable approach to long-term preservation of data, and providing a suite of services to users of the system. In this thesis, we describe how digital library techniques can be employed to provide solutions to these problems and describe our experiences in creating a prototype for ETANA-DL. ETANA-DL is a model-based, componentized, extensible, archaeological Digital Library that manages complex information sources using the client-server paradigm of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We have designed and developed the prototype system with the following main goals: 1) to achieve information sharing between different heterogeneous archaeological systems, 2) to make primary archaeological data rapidly available to users, 3) to provide useful services to users of the DL, 4) to elicit requirements that users of the system will have beyond the services that it supports, and 5) to provide a sustainable solution to long-term preservation of valuable archaeological data. Consequently, we describe our approach to handling heterogeneous archaeological information from disparate sources; suggest an architecture for ETANA-DL, to be validated through prototyping; and show that given a pool of components that implement common DL services, a prototype DL can be rapidly created that supports several useful services over integrated data. Further, and most fundamentally, we note that understanding complex information systems is a difficult task. Finally, therefore, we describe our efforts to model complex archaeological information systems using the 5S framework, and show how we have used the resulting partial models to implement ETANA-DL with cross-collection searching and browsing capabilities.Master of Science

Library and information services in corporations, schools, universities, and communities capture information about their users, circulation history, resources in the collection, and search patterns (Koenig, 1985). Unfortunately, few libraries have taken advantage of these data as a way to improve customer service, manage acquisition budgets, or influence strategic decision-making about uses of information in their organizations. In this chapter, we present a global view of the data generated in libraries and the variety of decisions that those data can inform. We describe ways in which library and information managers can use data mining in their libraries, i.e. bibliomining, to understand patterns of behavior among library users and staff members and patterns of information

Full textAbstract:
In this report the rendering performances of the multimedia libraries Allegro, SDL and SFML have been compared. Highest performance is achieved by writing code directly to the low level graphical APIs, though it requires much more work than using the multimedia libraries graphical functions built on one of these graphical APIs. Thus it is common to use a multimedia library or similar for visualization tasks. The total number of frames rendered in one second was counted for static, alpha blended, rotating, and moving images in each library. Every test was run with few to very many images, and the programs were tested on six different computers: three laptops with integrated GPUs and low power dual core CPUs, and three desktop computers with external GPUs and quad core CPUs with unlocked clock rate. Allegro performed best of the three on laptops when the image load was very high, but fell behind by up to 50% in all other cases. SDL had the strongest performance on desktop computers, especially when rendering very many images, making it a prime candidate for high load graphical applications on desktops. SFML performed best overall, making it the best choice when targeting a wide range of different machines.I denna rapport jämförs renderingsprestandan mellan multimediabiblioteken Allegro, SDL och SFML. Den högsta prestandan uppnås genom att skriva kod direkt till en lågnivå-API för grafik, men det kräver mycket mer kod än att använda ett multimediabibliotek. Därför är det vanligt att använda ett multimediabibliotek eller något med liknande funktioner för visualiseringsarbeten. Jämförelsen bestod av att räkna det totala antalet skärmbilder som renderades under en sekund för statiska, semitransparanta, rotarande och rörliga bilder. Varje test kördes med 50 till 10 000 bilder som renderades samtidigt, och programmen testades på sex olika datorer, tre bärbara med integrerade GPUs och tvåkärniga energieffektiva CPUs, och tre stationära med externa GPUs och fyrkärniga CPUs med upplåst klockfrekvens. Allegro presterade bäst på bärbara datorer under en hög belastning, men var upp till 50% sämre i alla övriga tester. SDL presterade bäst på stationära datorer, därför är det ett bra val för krävande grafiska program på stationära datorer. SFML presterade bäst överlag, vilket gör det till det bästa valet för att skapa grafiska program som är tänkta att köras på olika starka datorer.

Full textAbstract:
The motivation for this work is based on two recognized research issues for digital libraries. One is the need for interlinked and semantically rich information spaces where relationship information is of particular importance. The other is the serviceoriented architecture of digital libraries. The digital libraries of the future will consist of smaller and independent systems that each will provide different functionality and access to different contents.
This work defines and explores a service for managing and using explicit relationships – the Digital Library Link Service. The service implements an instance-oriented approach to relationships that enables any kind of typed relationship to be created among the information objects of digital libraries. The service can be used to create consistent information spaces on top of digital library repositories and enables an associative organization and retrieval of information objects.
This work shows that the use of a fine-grained relationship model implemented as distributed objects enables distribution of the relationship network while still being able to support constraints and maintain consistency. The cost of this, however, is a complexity that can reduce performance and scalability due to the call latency of network communication. A prototype is developed that utilizes caching in order to solve this. Tests conducted show that this technique significantly contributes to the scalability and efficiency. This is particularly important when the relationship information is distributed across different processes with high calllatency in between.
The work further presents a prototype application for enhancing bibliographic catalogues with the rich set of relationship types defined in the bibliographic information model proposed by the International Federation of Library Associations and Institutions – the FRBR model. The Digital Library Link Service is used to implement an index that facilitates the navigation of bibliographic relationships in order to explore bibliographic entities along the paths laid out by the FRBR model. This demonstrates the applicability of the service as a flexible tool for associative organization of information objects.
The main applications of the service are limited to systems with a relaxed requirement in terms of automatic processing of larger sets of relationships. The main access paradigm explored for interacting with relationships is by navigation. The need for automatic and efficient processing of a large relationship network, e.g. for the purpose of indexing, can be supported by extending the system with additional functionality. Another recognized problem is that the use of CORBA references to address long-term persistent information can cause referential integrity problems. One possible way to solve this is to assigning objects globally unique identifiers that later can be used to recover from referential integrity problems.

Full textAbstract:
The library was one of the most important institutions in the Hellenistic and Roman city, as evidenced in the writings of ancient authors, and the building remains of libraries found throughout the Greco-Roman world, from Asia Minor to France and from Africa to Northern Greece. Yet, the library remains one of the least easily identifiable building forms and one of the most difficult to reconstruct, because unlike architectural types such as the temple, stoa, or theater, the library exhibits significant variety in design, scale and monumentality and the use of different component elements.
In reconstructing libraries, scholars often rely on a prescribed set of assumptions about components and their arrangement that limit our ability to identify libraries and understand their diversity of arrangement. This dissertation proposes shape grammars as an effective computational methodology to identify, understand, and reconstruct ancient libraries of diverse and variant scale, design and monumentality. The work presents a comprehensive documentation of known and identified libraries, reviews the design principles of the architectural form of ancient libraries, and on the basis of this historical analysis proposes a shape grammar for the formal specification of ancient Greek and Roman libraries.
The library grammar encodes the design principles of ancient libraries in ninety-one rules
that are grouped in two major parts: the first generates the main hall of the library and its interior design, and the second generates the complete layout of the library including additional porticoes, peristyles, exedras, gardens and propylon. The application of the rules generates libraries of diverse scales and monumentality: libraries known in the corpus and as well as hypothetical libraries.
The dissertation presents grammatical derivations for the seventeen known and identified libraries. These derivations, depending on the degree of preservation of the building remains of libraries, function as an evaluative tool for the validity of the grammar or for the reconstructions proposed by traditional research. In many cases, they point to different possibilities in the identification of the building remains related to libraries among remains of different phases or remains belonging to neighboring buildings, and suggest variant scenarios of reconstruction that might not stand out using traditional techniques of reconstruction. The metadata of the rules in the grammar and the derivations are used in a frequency analysis that provides a probabilistic model as an effective and systematic guide in identifying, evaluating and predicting the architectural form of libraries: the main hall and the threshold are identified as mandatory architectural components, the niches and focal point as most likely, and the podium with a colonnade as less likely to occur in a library. Less frequently, the library is a whole complex with exedras, a monumental entry and additional rooms that function as auditoria, banquet halls or offices.
Moreover, the work presents the derivations of possible libraries and evaluates the rules applied to generate them based on the frequency analysis. In the end, the work concludes
whether these buildings are libraries, non-libraries or exceptional libraries.
Lastly, this dissertation assesses the opportunities and challenges that emerge in using shape grammars to identify and reconstruct libraries and also the value and impact of using formal computational methods in the systematic exploration of variations in reconstruction of the archaeological record.

Full textAbstract:
The purpose of this study was to understand undergraduate students’ attitudes about search data privacy in academic libraries and their preferences for how librarians should handle information about what students search for, borrow, and download. This is an important area of study due to the increasingly data-driven nature of evaluation, accountability, and improvement in higher education, along with libraries’ professional commitment to privacy, which has historically limited the amount of data collected about student use. Using a qualitative approach through the lens of interpretive description, I used the constant comparative method of data collection and analysis to conduct semi-structured interviews with 27 undergraduate students at a large, urban public research institution. Through inductive coding, I organized the data into interpretive themes and subthemes to describe students’ attitudes, and developed a conceptual/thematic description that illustrates how they are formed.
Students revealed that a variety of life experiences and influences shaped their views on search data privacy in academic libraries. They viewed academic library search data as less personally revealing than internet search data. As a result, students were generally comfortable with libraries collecting search data so long as it is used for their benefit. They were comfortable with data being used to improve library collections and services, but were more ambivalent about use of search data for personalized search results and for learning analytics-based assessment. Most students expressed a desire for de-identification and user control of data. Some students expressed concern about search data being used in ways that reflect bias or favoritism. Participants had moderate concern about their library search data privacy being used by government agencies to protect public safety. Although some disagreed with the practice in concept, most did not feel that the search data would be useful, nor would it reveal much about their personal interests or selves. Students who were not comfortable with the idea of search data collection in academic libraries often held their convictions more strongly than peers who found the practice acceptable.
The results of this study suggest that academic libraries should further explore student perspectives about search data collection in academic libraries to consider how and if they might adjust their data collection practices to be respectful of student preferences for privacy, while still meeting evaluation and improvement objectives. This study achieved the intended purpose of contributing a foundational body of knowledge about student attitudes regarding search data privacy in academic libraries. It positions librarian-researchers to develop studies that further this line of inquiry in an area that has significant implications for both user privacy and libraries’ practices for assessment and evaluation.
Limitations of this study include its limited generalizability as a result of the qualitative research design, and the fact that it relied primarily on a convenience sampling method.

Full textAbstract:
Philosophiae Doctor - PhDThis study investigates the relevance of quality measurement indicators at higher education libraries for faculty academics, librarians, and students. The study followed a mixed-method design with a mixture of quantitative and qualitative data collection. Faculty academics, librarians and students ranked the existing quality measurement indicators for South African higher education libraries. The findings revealed that for library quality measures to meet the needs of faculty academics, librarians, and students, the resources must be accessible both physically and virtually, and staff should be accountable and willing to offer services responsive to the users' needs and expectations of a safe, secure, and comfortable library space, be it physical or virtual. The qualitative data highlighted the importance of adequate resources and the adoption of new developments as measures for quality. Quality measurement indicators must include elements such as adequate funding; relevant resources aligned with teaching and learning programmes; programmes that are integrated into teaching plans; effective supplier collaboration with respect to the process of acquiring relevant learning materials; effective student training; communication of the value of library services and alignment with the student learning outcomes; research support in a digital environment with e-tools and website navigability; research data management; and open access, which is a prominent role of the library. Based on the data, there was a quality measure (process) that was commendable even though it did not form part of the existing quality measures nor a service whose relevance was assessed. The separation of undergraduate and postgraduate learning spaces was amongst those services that ranked quite high from the students' responses (qualitative data). Even though there were differences emphasized on each indicator by either faculty academics or students, there were also discrepancies in the interpretation of what each quality indicator means to each study population group. As the study of this nature has recommendations and gaps identified in terms of research findings, it is quite important to record that there was a series of gaps that were identified in terms of library expectations and perceptions. These gaps were suggested as part of further research that must be conducted to fill the void in terms of library users’ voices in the development of higher education library measurement indicators.

Full textAbstract:
DNA-encoded chemical libraries (DEL) allows an exhaustive chemical space sampling with a large-scale data consisting of compounds produced through combinatorial synthesis. This novel technology was utilized in the early drug discovery stages for robust hit identification and lead optimization. In this project, the aim was to build a Machine Learning- based QSAR model with conformal prediction for hit identification on two different target proteins, the DEL was assayed on. An initial investigation was conducted on a pilot project with 1000 compounds and the analyses and the conclusions drawn from this part were later applied to a larger dataset with 1.2 million compounds. With this classification model, the prediction of the compound activity in the DEL as well as in an external dataset was aimed to be analyzed with identification of the top hits to evaluate model’s performance and applicability. Support Vector Machine (SVM) and Random Forest (RF) models were built on both the pilot and the main datasets with different descriptor sets of Signature Fingerprints, RDKIT and CDK. In addition, an Autoencoder was used to supply data-driven descriptors on the pilot data as well. The Libsvm and the Liblinear implementations were explored and compared based on the models’ performances. The comparisons were made by considering the key concepts of conformal prediction such as the trade-off between validity and efficiency, observed fuzziness and the calibration against a range of significance levels. The top hits were determined by two sorting methods, credibility and p-value differences between the binary classes. The assignment of correct single-labels to the true actives over a wide range of significance levels regardless of the similarity of the test compounds to the training set was confirmed for the models. Furthermore, an accumulation of these true actives in the models’ top hit selections was observed according to the latter sorting method and additional investigations on the similarity and the building block enrichments in the top 50 and 100 compounds were conducted. The Tanimoto similarity demonstrated the model’s predictive power in selecting structurally dissimilar compounds while the building block enrichment analysis showed the selectivity of the binding pocket where the target protein B was determined to be more selective. All of these comparison methods enabled an extensive study on the model evaluation and performance. In conclusion, the Liblinear model with the Signature Fingerprints was concluded to give the best model performance for both the pilot and the main datasets with the considerations of the model performances and the computational power requirements. However, an external set prediction was not successful due to the low structural diversity in the DEL which the model was trained on.

Full textAbstract:
Today’s software development heavily relies on the use of third-party libraries. However, some libraries have a rich set of functionalities where only a few of them are used. This leads to an unnecessary complex codebase that needs maintenance. This thesis compares two methods used to calculate the ratio of used code in the third-party libraries. The first method uses the already existing tool JTombstone, which analyses the code statically. This static approach always examines the whole program. However, it overestimates the result. The second method uses a dynamic approach. This method always underestimates the result, because, only the part of the program which is executed will be examined. The dynamic code analyser tool modifies all classes which contains in the third-party library. At the beginning of every method a print statement is added, which prints the signature of the current method. In this way, the list of all executed methods is generated. The findings of the thesis are that the first approach always yields higher value and the difference between the two methods decreases while the code coverage increases. The thesis cannot state which method is the best; however, a good solution is to combine both methods to generate an interval which bound the correct value.Dagens mjukvaruutveckling förlitar sig mycket på användningen av tredjepartsbibliotek. Emellertid innehåller många av biblioteken mycket funktionalitet men bara en liten del av dem används. Det här skapar onödigt komplex mjukvara som måste underhållas. I den här uppsatsen jämförs två olika metoder som används för att beräkna andelen använd kod i tredjepartsbibliotek. Den första metoden använder JTombstone, det här verktyget analyserar koden statiskt. Eftersom den analyserar koden statiskt kommer hela projektet alltid bli analyserat, däremot kommer verktyget beräkna ett för högt värde. Den andra metoden bygger istället på en dynamisk utvärdering av koden. När man använder ett dynamiskt tillvägagångsätt så utvärderas bara den delen av koden som kördes, det här leder till att programmet kommer att generera ett för lågt resultat. Verktyget som analyserar koden dynamiskt modifierar alla klasser som tillhör tredjepartsbiblioteket. I början av varje metod lägger verktyget till en utskrift, som skriver ut metodsignaturen för den specifika metoden. På så sätt erhålls en lista av metoderna som har blivit anropade. Uppsatsen kom fram till att den första metoden alltid genererar ett större värde. Resultaten visar också att skillnaden mellan de två metoderna minskar när testerna testar en större del av koden. Med de resultat som genererades går det inte att avgöra vilken av de två metoder som är bäst. En bra lösning är att kombinera metoderna och med hjälp av de två resultaten skapa en övre och undre gräns för det korrekta värdet.

Ahmad, Pervaiz. "E-book adoption in academic and research libraries." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2015. https://ro.ecu.edu.au/theses/1601.
Full textAbstract:
Electronic books (e-books) have grown in importance in Academic and Research Libraries (ARLs). Some ARLs are now spending more on e-book acquisitions than hardcopy books. Whether this investment in e-book provision is justified by adoption outcomes is often the subject of simplistic, rather than rigorous research. This research has attempted to rigorously explore the phenomenon of e-book adoption in a case study ARL, namely, Edith Cowan University (ECU) Library.
The study population consisted of ECU academics, students and non-academic staff. The research had three aims. First, by employing a theoretical framework based on technology adoption and information behaviour theory, the study sought explanations of adoption behaviours in the population. In a triangular research design, that included a survey, ECU users were invited to self-describe their own patterns of e-book behaviour. Survey data was used to determine if behaviour observed in transactions could be explained in terms of constructs derived from technology acceptance, information behaviour and other domain theories that seek to understand user interaction with information sources. Next, applying log analysis techniques to system-generated datasets of e-book usage, the researcher documented and analysed patterns of ECU e-book user behaviour in terms of the transaction record. Lastly, the study investigated whether transaction logs could be used with high reliability to profile users’ information behaviour providing the basis of a method for e-book individualisation. The study attempted to profile power users and to derive a predictive method for identifying them in log data.
The study found many factors in technology acceptance theory that were significant in terms of adoption behaviour. E-book adoption in the case study ARL was found to be related to culture of use across the dimensions of habit/automaticity, preference for online resources and platforms, and information literacy. E-book collection sufficiency, purpose or task fit, convenience, functionality, and access/copy/print/download provisions were found to be significant in terms of performance expectancy. Dimensions of effort expectancy in finding/searching/reading e-books also significantly affected user behaviour. Other significant relations comprised perceived e-book hedonic attributes (pleasantness of experience, attractiveness of formats), familiarity (awareness, prior experience, differentiability), intimacy (personal likeness, emotional attachment, preferences), facilitating conditions (such as discovery, findability, connectivity/access, courseware embedded links), moderating factors (including respondent category, student programme, age, gender, and experience/years). These factors were found to be significant as sources of gratification and continuance intention.
An original contribution to knowledge was also made by deriving a predictive equation for classifying users based on transaction log data. Further, the research developed a new model of higher level information behaviours displayed by sophisticated or so-called ‘power users,’ and generated a model of e-book information behaviour maturity that distinguishes nascent from mature behaviours. The model is grounded in self-reported information behaviour. As an expansive exploration of e-book usage patterns in a case study ARL using multiple methods, the work is also innovative both in terms of scope and as an exploration of e-book adoption in an Australian context. This research is significant in laying the foundations for machine-based user profiling and enhanced individualisation of e-books to make for more satisfying user experience and acceptance of e-books.

Archeological research embracing complex Information Technology techniques can result in vast quantities of heterogeneous information from different sites in different formats. ETANA-DL is an Archeological Digital Library (DL), providing services suited for the archeological domain. With a growing collection of records in the DL, it is a challenge to present them in an organized and meaningful way. We have designed a new visual browsing interface called ETANA-CMV that aims to provide users a richer and more insightful browsing experience. ETANA-CMV allows users to navigate through the records in ETANA-DL that are multidimensional, hierarchical, and categorical in nature. ETANA-CMV was designed to be scalable, flexible, and easy to learn.
This interface employs a data cube based browsing index to counter performance issues that usually limit the interactivity of visual browsing interfaces to DLs. The interface has been integrated with the existing Browse Interface and the search service in ETANA-DL. Formative evaluation of the new visual interface led to several improvements in the interface. It appears that users were able to detect trends in the DL collections more accurately using visualization based strategies than with the existing textual browse interface.

Full textAbstract:
This study has three major purposes: to describe systematically the practice of
librarianship in Australian Commonwealth Government departments and agencies
from the perspective of librarians employed in that environment; to relate the
characteristics of government librarianship to librarians' perceptions of and
attitudes to their work; and to assess the extent to which the work of Commonwealth
Government librarians needs to be redesigned to improve the level of job satisfaction
they experience. A subsidiary purpose is to test the job characteristics theory of
work motivation on a population of librarians.
Information was gathered by a survey questionnaire on a range of variables relating
to librarians and their perceptions of different aspects of their jobs. The primary
instrument for gathering data on perceptions was the complete form of the Job
Diagnostic Survey.
The population under investigation comprised those Commonwealth Government
department and agency librarians employed on a full-time, permanent basis under
the Public Service Act 1922. and located in Canberra. Because the population was
small but diverse, it was decided to survey the total population rather than a random
or stratified sample. One hundred and eight usable responses were received which
represented a response rate of 83 percent.
The results of the survey were analysed using the Statistical Package for the Social
Sciences. Frequency distributions and Pearson's Product-Moment Correlations were
calculated to determine the percentage of respondents who selected each option and the
strength of relationships between pairs of variables.
The study found that Commonwealth Government department and agency librarians in
Australia are highly satisfied with their work generally, and with the environment
in which it is performed. None of the null hypotheses relating to Commonwealth
Government librarians and job satisfaction were rejected. All but one of the null
hypotheses retating to the application of the job characteristics model to
Commonwealth Government librarians are rejected.
The study concludes by identifying issues and areas for further research in public
sector librarianship.

The purpose of this thesis is to experimentally determine the feasibility of an ejector based, waste heat recovery driven refrigeration system applied to the data center environment in order to reduce operational cooling costs. A comprehensive literature review is detailed to determine the current state of the ejector refrigeration research and assess the initial direction of this thesis. A simplified model was created to perform preliminary performance estimations and system sizing before constructing an experimental system apparatus to evaluate the model predictions. The pressures and temperatures used in the model and instituted in the experimental system are based on the maximum temperatures typically observed in computing servers (50-75°C). Precision controlled heaters are used to simulate the computer server heat, and R245fa is used as the working fluid. Performance results ranged from 0.06 to 0.13.

Introduction: In the present paper we will seek to place the design of hypermedia-based user interfaces in the appropriate context of user-centred system design. In so doing we will outline what we believe to be the major methodological issues. As this will indicate, we view hypermedia design as essentially no different from any other kind interface design in terms of process and problem. Hence the methodological issues for hypermedia interfaces need to be seen as design problems rather than cognitive scientific ones. In this vein, we argue for a data-driven approach to design that seeks theoretical insight at the methodological and process level of design rather than the user level.

Full textAbstract:
This thesis reports on a research project undertaken over a four year period investigating and developing a software framework and application for integrating and managing building product information for construction engineering. The research involved extensive literature research, observation of the industry practices and interviews with construction industry practitioners and systems implementers to determine how best to represent and present product information to support the construction process. Applicable product models for information representation were reviewed and evaluated to determine present suitability. The IFC product model was found to be the most applicable. Investigations of technologies supporting the product model led to the development of a software tool, the IFC Assembly Viewer, which aided further investigations into the suitability of the product model (in its current state) for the exchange and sharing of product information. A software framework, or reusable software design and application, called PROduct Information Management System (PROMIS), was developed based on a non-standard product model but with flexibility to work with the IFC product model when sufficiently mature. The software comprises three subsystems namely: ProductWeb, ModelManager.NET and Product/Project Service (or P2Service). The key features of this system were shared project databases, parametric product specification, integration of product information sources, and application interaction and integration through interface components. PROMIS was applied to and tested with a modular construction business for the management of product information and for integration of product and project information through the design and construction (production) process.

Full textAbstract:
Bibliotecas digitais são repositórios de objetos digitais que oferecem serviços aos seus usuários como pesquisa e publicação desses objetos. Cada objeto digital é descrito por um conjunto de metadados que especifica a forma como esse objeto pode ser recuperado. Sistemas de integração de bibliotecas digitais indexam objetos digitais adquiridos de fontes diferentes, os quais podem estar representados através de vários padrões de metadados. Estes metadados são heterogêneos tanto em conteúdo quanto em estrutura. Conseqüentemente, os sistemas de integração de bibliotecas digitais não estão aptos a fornecer respostas livres de informação redundante que integrem as várias fontes de dados. Quando um usuário realiza uma consulta sobre várias bibliotecas digitais, é interessante que sejam retornados metadados integrados das diversas fontes e a origem de cada informação recuperada, ou seja, a biblioteca digital que publicou aquela informação (metadado). O uso de proveniência de dados nas consultas a metadados em sistemas de integração de bibliotecas digitais, de modo a rastrear a origem das informações recuperadas, permite que usuários avaliem a qualidade das bibliotecas digitais. Este trabalho apresenta o MD-PROM (Metadata Deduplication and PROvenance tracing Mechanism), um mecanismo de deduplicação de metadados e rastreio da proveniência. Este mecanismo identifica metadados de objetos digitais duplicados em bibliotecas digitais distintas, integra os metadados duplicados e recupera informações de proveniência dos metadados integrados. A identificação de duplicatas é realizada através do casamento automático de esquemas dos metadados e da aplicação de funções de similaridade sobre os principais metadados que descrevem os objetos digitais. São propostas a função de similaridade de nomes próprios IniSim, o algoritmo de casamento de autores NameMatch e o algoritmo de casamento de objetos digitais Digital Object Match que identifica múltiplas representações dos metadados. Além dos algoritmos de similaridade, o MD-PROM especifica uma estrutura baseada em árvore para representar a proveniência de dados que identifica a origem dos metadados, bem como os valores dos quais os metadados foram derivados. Também é proposto um algoritmo de integração de metadados e rastreio da proveniência denominado MetadataProv. A principal contribuição do trabalho é melhorar a qualidade da pesquisa do usuário de bibliotecas digitais. O MD-PROMfornece uma resposta única, livre de redundância e sem perda de informação relevante para consultas a metadados de objetos digitais oriundos de bibliotecas digitais distintas. Além disso, são recuperadas informações de proveniência que permitem ao usuário verificar a veracidade e confiabilidade dos metadados retornados pelas consultas em sistemas de integração de bibliotecas digitais. São apresentados também os resultados de diversos experimentos que avaliam a qualidade da deduplicação de objetos digitais comparando a técnica proposta com outras abordagens estudadas.Digital libraries are repositories of digital objects that provide services to their users such as search and publication of these objects. Each digital object is described by a set of metadata that specifies how this object can be retrieved. Integrated digital library systems index digital objects acquired from different sources, which can be represented through several metadata patterns. These metadata are heterogeneous both in content and in structure. Consequently, the integrated digital library systems are not able to provide answers free from redundant information that integrate the several data sources. When a user performs a query on various digital libraries, it is interesting to return integrated metadata from several sources and the origin of each information retrieved, that is, the digital library which published that information (metadata). Using data provenance in metadata queries on integrated digital library systems, so as to trace the origin of the information retrieved, allows users to analyze the quality of digital libraries. This work presents MD-PROM (Metadata Deduplication and PROvenance tracing Me- chanism), a mechanism for metadata deduplication and provenance tracing. This mechanism identifies duplicated digital objects metadata in different digital libraries, integrates duplicated metadata and retrieves provenance information of the integrated metadata. The identification of duplicates is performed through automatic metadata schema matching and through similarity functions applied over main metadata that describe the digital objects. The surname similarity function IniSim, the authors matching algorithm NameMatch and digital objects matching algorithm Digital Object Match, which identifies multiple representations of metadata, have been proposed. Besides the similarity algorithms, MD-PROM specifies a tree-based structure to represent the data provenance that identifies the origin of metadata as well as the values from which the metadata were derived. An algorithm for the integration of metadata and provenance tracing, called MetadataProv, is also proposed. The main contribution of this work is to improve the quality of the searches posed by the users of digital libraries. MD-PROM provides a single answer, free from redundancy and loss of relevant information related to queries on digital objects metadata from different digital libraries. In addition, provenance information is retrieved allowing the user to verify the accuracy and the reliability of the metadata returned by queries on integrated digital library systems. There are also reports on several experiments, which evaluate the quality of the deduplication of digital objects comparing the proposed technique with other approaches.

This study evaluates the data sources and research methods used in earlier studies to rank the research productivity of Library and Information Science (LIS) faculty and schools. In doing so, the study identifies both tools and methods that generate more accurate publication count rankings as well as databases that should be taken into consideration when conducting comprehensive searches in the literature for research and curricular needs. With a list of 2,625 items published between 1982 and 2002 by 68 faculty members of 18 American Library Associationâ (ALA-) accredited LIS schools, hundreds of databases were searched. Results show that there are only 10 databases that provide significant coverage of the LIS indexed literature. Results also show that restricting the data sources to one, two, or even three databases leads to inaccurate rankings and erroneous conclusions. Because no database provides comprehensive coverage of the LIS literature, researchers must rely on a wide range of disciplinary and multidisciplinary databases for ranking and other research purposes. The study answers such questions as the following: Is the Association of Library and Information Science Educationâ s (ALISEâ s) directory of members a reliable tool to identify a complete list of faculty members at LIS schools? How many and which databases are needed in a multifile search to arrive at accurate publication count rankings? What coverage will be achieved using a certain number of databases? Which research areas are well covered by which databases? What alternative methods and tools are available to supplement gaps among databases? Did coverage performance of databases change over time? What counting method should be used when determining what and how many items each LIS faculty and school has published? The authors recommend advanced analysis of research productivity to provide a more detailed assessment of research productivity of authors and programs.

A publicação de trabalhos científicos é uma das principais formas de avanço da Ciência, dando aos autores o reconhecimento de seu trabalho por parte da comunidade científica. A divulgação de trabalhos publicados é de grande interesse tanto da parte de quem os desenvolve (autores), quanto de quem pode vir a se beneficiar dos resultados (a comunidade científica em geral). Neste contexto, as bibliotecas digitais surgem como uma alternativa para simplificar o processo de publicação de artigos. Nelas encontram-se repositórios de dados que possuem informações sobre os artigos publicados bem como links para os próprios artigos, ou mesmo os arquivos propriamente ditos. Dois pontos importantes na implementação e uso de bibliotecas digitais são a interoperabilidade e a padronização dos metadados que serão utilizados pelos repositórios. Essas questões podem ser resolvidas através da OAI (Open Archives Initiative) e pelo formato Dublin Core. Um exemplo de biblioteca digital que utiliza o padrão OAI é a BDBComp (Biblioteca Digital Brasileira de Computação), que disponibiliza os metadados sobre os artigos publicados nos eventos de computação no Brasil. Por outro lado, a SBC (Sociedade Brasileira de Computação) disponibiliza aos eventos que promove (e atualmente também a alguns eventos internacionais) o sistema JEMS para o gerenciamento das submissões dos artigos. Através dele os artigos são avaliados, e é feita a seleção daqueles que serão publicados em cada evento ou periódico que utiliza o sistema. Neste trabalho é apresentado um serviço de geração de metadados compatível com o padrão OAI, desenvolvido para disponibilizar os metadados sobre os artigos publicados nas conferências ou periódicos que utilizem o JEMS. Os metadados gerados são disponibilizados para bibliotecas digitais, como a BDBComp. O serviço é de fato um provedor de dados OAI, que utiliza dados provenientes do sistema JEMS e os disponibiliza no formato Dublin Core a bibliotecas digitais através do protocolo OAI-PMH, o qual é baseado em XML. Este provedor de dados foi desenvolvido para uso com a biblioteca digital da SBC, e oferece um aumento da quantidade e da qualidade dos metadados disponibilizados sobre os artigos publicados nos eventos e periódicos gerenciados pelo JEMS.The publication of scientific works is one of the greatest forms of Science progress, giving the authors recognition from scientific community about their work. The publication spreading is of great interest for both the authors and those that can be benefited from the results. In this context, the digital libraries appear as an alternative to simplify the paper publication process. They own data repositories that have information about published papers as well as links for the papers. Two important points in the implementation and use of digital libraries are metadata interoperability and metadata standadization. These questions can be solved by the OAI (Open Archives Initiative) and by the Dublin Core format. An example of digital library that uses the OAI standard is BDBComp (Biblioteca Digital Brasileira de Computação), which have metadata about papers published in computing science events in Brazil. On the other hand, SBC (Sociedade Brasileira de Computação) have the JEMS system for use in the management of paper submission for the events that SBC promotes (and nowadays for some international events too). Through JEMS the papers are evaluated, and a selection of the accepted papers can be done. This work presents an OAI-compatible metadata generation service developed to offer metadata about the papers published in conferences or journals that use JEMS. The generated metadata are made available to digital libraries, like BDBComp. The service is in fact an OAI data provider that uses data obtained from JEMS and offer the metadata in the Dublin Core format to digital libraries, through the OAI-PMH protocol, which is based on XML. This data provider was developed for use with the SBC’s digital library. It gives an improvement on the quantity and quality of the available metadata about the papers published by the events and journals managed by JEMS.

Full textAbstract:
While historically digital heritage libraries were first powered in image mode, they quickly took advantage of OCR technology to index printed collections and consequently improve the scope and performance of the information retrieval services offered to users. But the access to iconographic resources has not progressed in the same way, and the latter remain in the shadows: manual incomplete and heterogeneous indexation, data silos by iconographic genre. Today, however, it would be possible to make better use of these resources, especially by exploiting the enormous volumes of OCR produced during the last two decades, and thus valorize these engravings, drawings, photographs, maps, etc. for their own value but also as an attractive entry point into the collections, supporting discovery and serenpidity from document to document and collection to collection. This article presents an ETL (extract-transform-load) approach to this need, that aims to: Identify and extract iconography wherever it may be found, in image collections but also in printed materials (dailies, magazines, monographies); Transform, harmonize and enrich the image descriptive metadata (in particular with machine learning classification tools); Load it all into a web app dedicated to image retrieval. The approach is pragmatically dual, since it involves leveraging existing digital resources and (virtually) on-the-shelf technologies.Si historiquement, les bibliothèques numériques patrimoniales furent d’abord alimentées par des images, elles profitèrent rapidement de la technologie OCR pour indexer les collections imprimées afin d’améliorer périmètre et performance du service de recherche d’information offert aux utilisateurs. Mais l’accès aux ressources iconographiques n’a pas connu les mêmes progrès et ces dernières demeurent dans l’ombre : indexation manuelle lacunaire, hétérogène et non viable à grande échelle ; silos documentaires par genre iconographique ; recherche par le contenu (CBIR, content-based image retrieval) encore peu opérationnelle sur les collections patrimoniales. Aujourd’hui, il serait pourtant possible de mieux valoriser ces ressources, en particulier en exploitant les énormes volumes d’OCR produits durant les deux dernières décennies (tant comme descripteur textuel que pour l’identification automatique des illustrations imprimées). Et ainsi mettre en valeur ces gravures, dessins, photographies, cartes, etc. pour leur valeur propre mais aussi comme point d’entrée dans les collections, en favorisant découverte et rebond de document en document, de collection à collection. Cet article décrit une approche ETL (extract-transform-load) appliquée aux images d’une bibliothèque numérique à vocation encyclopédique : identifier et extraire l’iconographie partout où elle se trouve (dans les collections image mais aussi dans les imprimés : presse, revue, monographie) ; transformer, harmoniser et enrichir ses métadonnées descriptives grâce à des techniques d’apprentissage machine – machine learning – pour la classification et l’indexation automatiques ; charger ces données dans une application web dédiée à la recherche iconographique (ou dans d’autres services de la bibliothèque). Approche qualifiée de pragmatique à double titre, puisqu’il s’agit de valoriser des ressources numériques existantes et de mettre à profit des technologies (quasiment) mâtures.
