Zeitschriftenartikel zum Thema „Information storage and retrieval systems – Academic libraries“

Academic library professionals are now in uncharted territory. We’re hurtling through unfamiliar, rapidly shifting landscapes. Information storage and retrieval, scholarly publishing, information literacy: everything’s changing on a daily basis. Get hung up on any one thing, and you’re already working in the past. Allow yourself to be overwhelmed and you’re paralyzed.

The enormous growth in the size of scholarly literature makes its retrieval challenging. To address this challenge, researchers and practitioners developed several solutions. These include indexing solutions e.g. ResearchGate, Directory of Open Access Journals (DOAJ), Digital Bibliography & Library Project (DBLP) etc., research paper repositories e.g. arXiv.org, Zenodo, etc., digital libraries, scholarly retrieval systems, e.g., Google Scholar, Microsoft Academic Search, Semantic Scholar etc., digital libraries, and publisher websites. Among these, the scholarly retrieval systems, the main focus of this article, employ efficient information retrieval techniques and other search tactics. However, they are still limited in meeting the user information needs to the fullest. This brief review paper is an attempt to identify the main reasons behind this failure by reporting the current state of scholarly retrieval systems. The findings of this study suggest that the existing scholarly retrieval systems should differentiate scholarly users from ordinary users and identify their needs. Citation network analysis should be made an essential part of the retrieval system to improve the search precision and accuracy. The paper also identifies several research challenges and opportunities that may lead to better scholarly retrieval systems.

Purpose – The purpose of this paper is to discuss issues and concerns raised in a collaborative and cooperative central storage facility for Hong Kong academic libraries. Design/methodology/approach – The approach is to propose and to implement a joint storage business plan and a possibility of acting for others to consider similar storage facilities. Findings – Useful experiences have been gained while planning a central storage facility. Research limitations/implications – The proposed JURA project is for Hong Kong academic libraries. Practical implications – The sharing of JURA proposal to create a central storage will inform the libraries around the region of the benefits of having a useful facility in the long term. Originality/value – The paper will inform others wishing to set up collaborative storages on governance, storage systems, business plan, problems and issues in what is still a relatively unexplored approach to storage problems.

The adoption of information and communication technologies in information environment has made a radical change in information management. One of such revolutions has exhibited in the form of digital libraries. The evolution of digital libraries has ensured the emergence of global networked environment that has dramatically changed the status of libraries, their processes, service delivery as well as storage and retrieval systems. This paper examines the development of digital libraries, the concept, characteristics, funding, infrastructure, and ICT policy in Nigeria. The paper enumerates a number of challenges hindering the development of digital libraries in Nigeria and proffers some recommendations.

Purpose The purpose of this study is to investigate the use of integrated library system (ILS) in academic library operations in Edo and Delta states, Nigeria. Design/methodology/approach This study adopted a descriptive survey research design. Total enumeration was used since the population consisting 88 academic librarians in Edo and Delta states is not large and was considered appropriate to achieve the purpose of this study. Questionnaire titled “Assessment of adoption and use of Integrated Library Software (ILS) for library service provision in academic libraries in Edo and Delta States, Nigeria” was used. Before the administration of the questionnaire on the respondents, face validity was carried out to test the validity of the questions. The questionnaire was given to experts in the Department of Information Resources Management, Babcock University, Ilishan-Remo, Ogun State who validated, resolved defects and modified the questionnaire. Findings This study showed that there is a general non-use of ILS in academic libraries in Delta state. Findings revealed that three of the four academic libraries in Edo State adopted library software in their library operations except Ambrose Ali University Library, Ekpoma. Findings further showed that the ILS that were used in academic libraries in Edo State are effective. It also revealed that ILS is effective for accessing books and other library materials, retrieval of materials, bibliographic search and provision of links to external databases. Finding also indicated that among the library software that were used in academic libraries in this study, only Koha ILS has the capacity to link to external databases. Practical implications The use of ILS in academic library operation is critical. Its adoption and use to a large extent positively affect the library and its users. Non-adoption and use of ILS in most academic libraries is a setback to delivery of quality library services to clientele. Originality/value This study is the first that assessed the adoption and use of ILS in academic libraries is Edo and Delta states. It exposed the level of adoption and utilization of ILS in library operations with a view to encouraging libraries to adopt and use ILS for library services.

Advances in information storage and image acquisition technologies have enabled the creation of enormous image datasets. during this situation, it's necessary to develop applicable data systems to with efficiency manage these collections. the most typical approaches use the supposed Content-Based Image Retrieval (CBIR) systems. Basically, these systems attempt to retrieve pictures like a user-defined specification or pattern (e.g., form sketch, image example). Their goal is to support image retrieval supported content properties (e.g., shape, color, texture), typically encoded into feature vectors. one among the most benefits of the CBIR approach is that the chance of AN automatic retrieval method, rather than the standard keyword-based approach, thattypically needs terribly toilsome and long previous annotation of info pictures. The CBIR technology has been utilized in many applications like fingerprint identification, variety data systems, digital libraries, crime bar, medicine, historical analysis, among others.

Purpose – The purpose of this paper is to use cloud storage in digital preservation by analyzing the pricing and data retrieval models. The author recommends strategies to minimize the costs and believes cloud storage is worthy of serious consideration. Design/methodology/approach – Few articles have been published to show the uses of cloud storage in libraries. The cost is the main concern. An overview of cloud storage pricing shows a price drop once every one or one-and-a-half years. The author emphasize the data transfer-out costs and demonstrate a case study. Comparisons and analysis of S3 and Glacier have been conducted to show the differences in retrieval and costs. Findings – Cloud storage solutions like Glacier can be very attractive for long-term digital preservation if data can be operated within the provider’s same data zone and data transfer-out can be minimized. Practical implications – Institutions can benefit from cloud storage by understanding the cost models and data retrieval models. Multiple strategies are suggested to minimize the costs. Originality/value – The paper is intended to bridge the gap of uses of cloud storage. Cloud storage pricing especially data transfer-out pricing charts are presented to show the price drops over the past eight years. Costs and analysis of storing and retrieving data in Amazon S3 and Glacier are discussed in details. Comparisons of S3 and Glacier show that Glacier has uniqueness and advantages over other cloud storage solutions. Finally strategies are suggested to minimize the costs of using cloud storage. The analysis shows that cloud storage can be very useful in digital preservation.

Purpose – Conducting academic searches within online digital libraries can be a difficult task due to the complexity of the searcher’s information need. The interfaces for such digital libraries commonly use simple search features that provide limited support for the fundamental strategies that academic searchers employ. The authors have developed a novel visualisation interface called Bow Tie Academic Search to address some of these shortcomings, and present in this paper the findings from a user evaluation. The paper aims to discuss these issues. Design/methodology/approach – A controlled laboratory study was conducted to compare a traditional search interface to Bow Tie Academic Search. In total, 24 graduate students were recruited to perform academic searches using the two candidate interfaces, guided by specific sub-tasks that focus on citation and keyword analysis strategies. Findings – Although the use of the core visualisation and exploration features did not reveal differences in retrieval effectiveness or efficiency, the query refinement features were found to be effective. Strongly positive impressions of usefulness and ease of use of all aspects of the system were reported, along with a preference for using Bow Tie Academic Search for academic search tasks. Originality/value – This study provides insight into the potential value for providing visual and interactive interfaces for supporting academic search tasks and strategies. While the quantitative improvements over the traditional search interface were minimal, the qualitative measures illustrate the value of Bow Tie Academic Search.

Reflections on three facets of professional art librarianship as experienced by the author over the past twenty years: the status of librarians, the status of the art library, information storage and retrieval. The University of Manitoba Faculty Association was one of the first in Canada to accept professional librarians as equal to faculty, a major step for the profession. Canadian librarians have played significant roles in the development of the Art Libraries Society of North America (ARLIS/NA) which from the beginning interested itself in collection development, technical practices of art libraries, and the needs, qualifications and physical surroundings of art librarians. The major technological development of the eighties for art libraries was not the widespread automation of major academic and public libraries, but the introduction of relatively inexpensive personal computers and attendant technology, which gives any library the capacity to access national and international databases and to assemble their files in a format which makes them readily available to a wider public.

Purpose – The purpose of this paper is to provide a detailed overview of the China Academic Library and Information system (CALIS) document supply service platform (CDSSP) – its historical development, network structure and future development plans – and discuss how its members make use of and benefit from its various components. Design/methodology/approach – The authors provide a first-person account based on their professional positions at the CALIS Administrative Center. Findings – CDSSP comprises five application systems including a unified authentication system, Saas-based interlibrary loan (ILL) and document delivery (DD) service system, ILL central scheduling and settlement system, File Transfer Protocol (FTP) service system and a service integration interface system. These systems work together to meet the needs of member libraries, other information service institutions, and their end users. CDSSP is widely used by more than 1,100 libraries based on a cloud service strategy. Each year more than 100,000 ILL and DD transactions are processed by this platform. Originality/value – The development of CDSSP makes it becomes true for CALIS to provide one stop information retrieval and supply service. At the same time, it promotes the resource sharing among member libraries to a great degree.

Libraries must play a role in knowledge management created by all academicians so that it can be used by anyone. This study analyzes publications about the role of libraries in supporting knowledge management. The data were obtained from the Scopus database. The retrieval technique is by entering the keywords "Knowledge Management" and "Library" with a publication year limitation between 1992-2020. The data obtained were then grouped based on the year of publication, publication source and type of literature. For keyword mapping, this study used VosViewer. The results of the analysis showed that research publications on the role of libraries in supporting knowledge management were mostly carried out in 2013 and 2016. Library Management is the journal that publishes the most literature related to this research object, there were 11 documents with a total of 185 citations, was in the form of articles. From the VosViewer mapping, it showed that there were four clusters. Research topics that were mostly carried out were knowledge management systems, knowledge management, libraries and information science, academic libraries, knowledge sharing, knowledge management models, librarians, research development management, information science, innovation, library services, and university libraries.

Purpose This paper aims to narrate the success story of Tekena Tamuno Library by harnessing the multi-dimensional advantages of digital repository management, including multiple access to documents, simultaneous use by multiple patrons and effective space management, to address the tug of war that used to ensue between students and circulation staff over retrieval and use of past examinations question papers in the library. Design/methodology/approach The paper analyzes and reports the situation before and after the creation of Redeemers University e-question bank. Findings Interpersonal conflicts that often accompanied manual management and circulation of past question papers in the library were removed by the intervention. The circulation area that was often rowdy and noisy prior to digitization is now neat, quiet and alluring to visitors. Patrons now have a good perception of the library and its staff, thereby giving the library good reputation within and outside the university community. Social implications The paper shows that digitization could help to resolve interpersonal conflicts often created by manual management of paper documents in academic libraries. Originality/value There is a dearth of literary evidence on how Nigerian libraries digitized past examination question papers. This paper has addressed this gap to some extent.

The relevance of the cognitive approach to the libraries and bibliography in the period of the society transformation from the information to the cognitive one is substantiated. Several trends in Russian and foreign studies of cognitive aspects of academic libraries activities are identified. The structure of library cognitive activities, their subjects and objects, processes, instruments and results are described. For the first time, based on the concept of cognitive activities, the author introduces the concept of the scientific library cognitive environment that is defined as an anthropogenic component of the library’s information space where cognitive objects and subjects are interacting and self-organizing being supported by cognitive infrastructure and related to information retrieval and processing, knowledge storage and preservation. The structure of the scientific library cognitive environment is defined based on the system of knowledge processes transformation; the environment components are intended for nonverbal transmission of implicit knowledge; conversion of implicit knowledge into explicit knowledge; distribution of bibliographic products; translation of explicit knowledge into the implicit form. The content and instrumental components of the cognitive environment are specified on account of cognitive objects. Specific features of the components are described. The author argues that there is the demand for developing librarian’s cognitive communications within the evolving scientific library cognitive environment and integration of librarians, being cognitive objects themselves, into the information technological Internet space. The article is sponsored by the RF Government (Order № 211 of March 16, 2013), Agreement № 02.А03.21.0011).

Purpose Modern technological solutions are rapidly changing the information landscape in library and information establishments. One such innovative solution that is gaining momentum in information centers is cloud computing. The purpose of this paper is to explore and compare opportunities and challenges of “cloud computing paradigm” in handling and supporting delivery of information services in university libraries in the face of the present hard economic situation and limited financial budgets. Design/methodology/approach The study is based on current academic literature, document analysis, several editorials and articles on the potential and challenges of cloud computing paradigm in university library and information centers. Findings Cloud computing is proving as the best management practice of salvaging information services in university libraries due to numerous competing challenges and issues in institutions of higher education. University libraries in developing countries face many challenges of inadequate information infrastructure, limited financial budgets, manpower issues and rapid changes in technological systems. In the context of hard economic times, cloud computing is critical in adding value as well as advancing the goals and objectives of modern university libraries. Cloud computing is the “best technology practice” that is poised to play crucial roles in enhancing quality provision and delivery of information services in university library and information centers. There are many competing challenges and claims, but potential benefits count more. Research limitations/implications The study is based on the ideas of cloud services conceptualized from reading academic literature, document analysis, several editorials, articles and professional work experience. The paper identifies that cloud computing paradigm is useful in achieving the goals and objectives of university libraries in this hard economic situation facing institutions of higher learning. Practical implications The paper provides practical insights that cloud computing is the “must have technology” for modern university library and information centers already burdened with the demand to develop effective and efficient technological solutions due to subsequent changing needs of the digital information environment. This study is useful for university libraries, information professionals, information communication technology professionals and university management. Social implications Cloud computing paradigm provides university libraries with the business opportunity to use comprehensive technological solutions with reduced capital expenditure and safe methods of data storage. This eases the inconveniences normally caused by the need to develop and own such comprehensive technological solutions. Originality/value This research looks at the potential of the emerging trend of “cloud computing paradigm” in enhancing quality provision and delivery of information services in university library and information centers in the context of limited financial budgets. Cloud computing has been gaining momentum in Kenya, especially in business organizations as compared to library and information establishments.

Purpose/thesis: The purpose of this paper is to answer the questions of whether and to what extent expert systems are currently used in library and information services. Attention is drawn to the fol­lowing elements of the information process: acquisition, storage and cataloging/description of infor­mation (search characteristics, search instruction), information retrieval (querying, natural language queries), transmission and implementation of information. Methods: The analysis of the literature acquired through queries in selected databases provided basis for the discussion of research trends in the field of expert systems as one of the methodologies of knowledge management using methods of artificial intelligence: problem solving and represen­tation of knowledge (knowledge generation, valuation and management, knowledge extraction and synthesis in the construction of expertise), „self-learning”, performance evaluation. In the final part of the paper an attempt was made to identify possible areas of expert systems application in libraries and information centers. Results:The research helped to specify the number of bibliographic records containing information about expert systems and recorded in selected databases. Expert systems vocabulary presented in the example thesaurus was discussed and the literature of the field was studied. Conclusions: The quantitative analysis of the literature showed a significant decrease in the number of publications on expert systems after 2010. Nevertheless, the expert systems (both experimental and operational) are used in numerous fields. It is expected that these systems will be used in spe­cialized libraries for the acquisition and codification of knowledge in selected areas of specialization.

Purpose – The aim of this study is to measure the perceptions of the Faculty of Economics of Tirana library users as they relate to quality service and to determine how far this library has succeeded in delivering such service to its users. Design/methodology/approach – The research was carried out among the students of the Faculty of Economics of Tirana. A questionnaire was used as the data gathering instrument. The instruments for data collection consisted of structured questions. All the closed ended questions were designed to elicit responses on a five point Likert scale to measure both respondent satisfaction and perception of service quality. Analysis of the collected data made use of the chi-square method. Findings – The results would appear to indicate that Faculty of Economics of Tirana library is not lacking in quality of service. However, we need to note that quality information service is about helping users to define and satisfy their information needs, building their confidence in using information retrieval systems, and making the whole activity of working with library staff a pleasurable experience. To achieve total quality in information service the Faculty of Economics of Tirana library should provide a comprehensive information programme that is predicated on the needs and activities of the users. Originality/value – This article may help those libraries, who are seriously interested to develop user satisfaction and provide better service to the user. This article also suggests some recommendations about increasing the user satisfaction in the library service.

Purpose – The purpose of this paper is to present the software architecture of the university’s union catalogue in Novi Sad, Serbia. The university’s union catalogue would comprise the collections of 14 academic libraries. Design/methodology/approach – The basis of this paper is a case study of developing a software solution for the union catalogue of the University of Novi Sad in Serbia. The solution principles of object-oriented modelling are applied to describe the software architecture. Specifically, the unified modeling language (UML) component and sequence diagrams are used. The database model is described by using a physical data model. Findings – Through the research of related papers and, taking into consideration the problem of creating a university union catalogue, it is concluded that the best approach is to combine the idea of a virtual and a physical union catalogue. Records are stored in one physical union catalogue, while the holdings data are stored in the local library management systems (LMSs) organized in the form of virtual union catalogues. Because academic libraries often use LMSs from different vendors, interoperable communication between those LMSs and the union catalogue is provided through the usage of standard library protocols for information retrieval (Search and Retrieve URL [SRU], SRU Record Update and NISO Circulation Interchange Protocol [NCIP]). Research limitations/implications – The development of a union catalogue for the University of Novi Sad is in its test phase, and, at this moment, only a software solution supporting the functionalities of a union catalogue has been created. Practical implications – By introducing a university union catalogue, students would be able to search the collections of all the university libraries by using a single portal. Their results would indicate whether a book is available and from which library it is available to borrow. Originality/value – Originality of this software architecture lies in the usage of standard library protocols. The described architecture enables the addition of new members to the university union catalogue, regardless of which LMS the library uses.

In the context of the development of modern information and communication environment, the top challenge of library institutions is to renew their activities and fill it with new functionalities. As science communications advance in accordance with the general evolution of the web sphere, the organization systems of information support for scientific research therefore undergo changes too. Scientific and academic libraries with their unique position in science communications are faced with the need to rethink their role and functions, with the problem of finding new ways of information and library support to research activities, and new services that meet the needs of modern scientists. Since one of the indicators for scientific institutions reporting is the number of institution references in the media, scientific libraries have begun to provide science news services. The authors consider the news information resources and services for scientific research institutions. The paper presents a brief description of news aggregator “Siberian Science News”, an information platform for distribution, storage and browsing of factual, bibliographic and full-text data. Based on this platform, staff members of the Branch of the State Public Scientific-Technological Library of the Siberian Branch of the Russian Academy of Sciences (SB RAS) have set up a service to provide specialists with information to maintain and update the online news feeds of the research institutions of the Novosibirsk Scientific Center of SB RAS. The authors note that currently, according to the preferences of subscribers, there are used two types of information-analysis reports based on media publications. The results of the conducted research allow the authors to conclude that there is a need for more active promotion of the resource “Siberian Science News” and the service for the maintenance of news information. In the case of the research institutions, the service maintains the development of their news pages and news feeds on the websites of organizations, which in turn makes the organizations more visible in science communication environment and promotes research areas and scientific results.

Content Based Image Retrieval (CBIR) techniques are becoming an essential requirement in the multimedia systems with the widespread use of internet, declining cost of storage devices and the exponential growth of un-annotated digital image information available in recent years. Therefore multi query systems have been used rather than a single query in order to bridge the semantic gaps and in order to understand user’s requirements. Moreover, query replacement algorithm has been used in the previous works in which user provides multiple images to the query image set referred as representative images. Feature vectors are extracted for each image in the representative image set and every image in the database. The centroid, Crep of the representative images is obtained by computing the mean of their feature vectors. Then every image in the representative image set is replaced with the same candidate image in the dataset one by one and new centroids are calculated for every replacement .The distance between each of the centroids resulting from the replacement and the representative image centroid Crep is calculated using Euclidean distance. The cumulative sum of these distances determines the similarity of the candidate image with the representative image set and is used for ranking the images. The smaller the distance, the similar will be the image with the representative image set. But it has some research gaps like it takes a lot of time to extract feature of each and every image from the database and compare our image with the database images and complexity as well as cost increases. So in our proposed work, the KNN algorithm is applied for classification of images in the database image set using the query images and the candidate images are reduced to images returned after classification mechanism which leads to decrease the execution time and reduce the number of iterations. Hence due to hybrid model of multi query and KNN, the effectiveness of image retrieval in CBIR system increases. The language used in this work is C /C++ with Open CV libraries and IDE is Visual studio 2015. The experimental results show that our method is more effective to improve the performance of the retrieval of images.

Purpose The key purpose of this study is to explore digital information literacy (DIL) possessed by South Valley University (SVU) library and information professionals. It also tries to identify the various types of DIL and find constraints affecting the related skills and competencies of those professionals. Design/methodology/approach A quantitative research methodology was adopted in the form of a survey, which was undertaken from February to March 2016. As stated by Kerlinger (1986), the survey research is a useful instrument for educational fact-finding, and a means by which much information can be acquired from the study’s population. The survey instrument was a self-administrated questionnaire, which was adopted for data collection. A pilot questionnaire was first sent to a small random sample of the respondents, with feedback being used to fine-tune the final questionnaire. The targeted population of this study included library and information professionals (n = 127) belonging to SVU libraries that spread over three provinces/campuses: the Qena campus (number of libraries = 22), the Luxor campus (n = 3) and the Hurghada campus (n = 2). The library and information professionals are described to be librarians, library assistants and library directors. Of 127 questionnaires, 101 (79.5%) responses were received. To collect data, the study used a questionnaire, which has six sections reflecting the research objectives of the study. Findings The findings showed that over two-thirds of SVU library and information professionals are males, and almost one-third are females. Majority respondents are aged between 26 and 40 years, and most possessed bachelor’s degrees, of which nearly two-thirds held library science degrees. Regarding the respondents’ professional profile, the study also showed that majority were librarians, followed by library assistants and library managers, and nearly half had 10 years of experience, followed by those who have work experience of 6-7 years. This study showed that there is a significant relationship between some of the respondents’ demographic characteristics (age and education) and their DIL. The respondents’ gender had no effect on their DIL. The study also showed that there is a significant relationship between all the respondents’ professional characteristics, particularly their discipline, followed by job title, work experience and DIL. Regarding the level of respondents’ knowledge of the types of computers, many showed that their knowledge of using mobile devices, followed by PCs, workstations, portable media players/digital audio player and personal digital assistant was, at the least, high. The respondents’ knowledge of other types ranged between moderate to non-proficient. A large number of the respondents showed that their proficiency in using output devices, followed by input devices, processing devices, storage devices and communication devices was also, at the least, high. While the largest number of the respondents showed that their proficiency in using application software was, at least, high, the largest number of them showed that their proficiency in using system software was moderate. Regarding the respondents’ knowledge-based competencies, as well as skills-based competencies, especially when these competencies related to the integration of ICTs into the library work, this study showed that such kind of competencies possessed by SVU library and information professionals ranged between competent and somewhat competent. Regarding the challenges affecting the respondents’ acquiring skills and related competencies, the study revealed that the lack of funds, training, physical facilities, connection to the internet, subscribing to e-databases, lack of time as well as challenges related to SVU library system regulations, were significant to them. Other challenges such as the lack of incorporating and exploiting the new technologies and products into library integrated systems educators’ services, as well as challenges related to psychological barriers, lack of current curricula in the area of ICTs and a shortage of experienced LIS counselors, were also significant to them. This study reached conclusions that the SVU library and information professionals should be qualified and get adapted to ICTs and related competencies. They need to be provided with sufficient training to update their knowledge regarding the use and integration of technology in their library work. Research limitations/implications This study investigates DIL among library and information professionals at SVU, an Egyptian university. Any findings and conclusions resulted from this study are limited in scope to only the library professionals of this university. Such a topic has limited previous research. The size and homogeneity of the sample limit the generalizability of this study. Practical/implications The study aims to investigate DIL acquired by SVU library and information professionals. The potential results of this study would be useful for library schools, library associations and other pertinent authorities for the planning of training programs and courses. The findings may also be helpful for library educators to develop curricula that meet the needs of library and information professionals. Originality/value This study is one of the few studies conducted on this topic in Egypt. The literature on the topic of this research revealed that extensive research has been undertaken on DIL in higher education in developed countries, but very limited research has been conducted on this topic in Egypt and similar developing countries, particularly among academic library and information professionals. No definition for the concept of DIL has yet been produced, and many Egyptian academic institutions define this concept based on their own needs depending on existing models.

Purpose – The purpose of this paper is to propose an automatic metadata extraction and retrieval system to extract bibliographical information from digital academic documents in portable document formats (PDFs). Design/methodology/approach – The authors use PDFBox to extract text and font size information, a rule-based method to identify titles, and an Hidden Markov Model (HMM) to extract the titles and authors. Finally, the extracted titles and authors (possibly incorrect or incomplete) are sent as query strings to digital libraries (e.g. ACM, IEEE, CiteSeerX, SDOS, and Google Scholar) to retrieve the rest of metadata. Findings – Four experiments are conducted to examine the feasibility of the proposed system. The first experiment compares two different HMM models: multi-state model and one state model (the proposed model). The result shows that one state model can have a comparable performance with multi-state model, but is more suitable to deal with real-world unknown states. The second experiment shows that our proposed model (without the aid of online query) can achieve as good performance as other researcher's model on Cora paper header dataset. In the third experiment the paper examines the performance of our system on a small dataset of 43 real PDF research papers. The result shows that our proposed system (with online query) can perform pretty well on bibliographical data extraction and even outperform the free citation management tool Zotero 3.0. Finally, the paper conducts the fourth experiment with a larger dataset of 103 papers to compare our system with Zotero 4.0. The result shows that our system significantly outperforms Zotero 4.0. The feasibility of the proposed model is thus justified. Research limitations/implications – For academic implication, the system is unique in two folds: first, the system only uses Cora header set for HMM training, without using other tagged datasets or gazetteers resources, which means the system is light and scalable. Second, the system is workable and can be applied to extracting metadata of real-world PDF files. The extracted bibliographical data can then be imported into citation software such as endnote or refworks to increase researchers’ productivity. Practical implications – For practical implication, the system can outperform the existing tool, Zotero v4.0. This provides practitioners good chances to develop similar products in real applications; though it might require some knowledge about HMM implementation. Originality/value – The HMM implementation is not novel. What is innovative is that it actually combines two HMM models. The main model is adapted from Freitag and Mccallum (1999) and the authors add word features of the Nymble HMM (Bikel et al, 1997) to it. The system is workable even without manually tagging the datasets before training the model (the authors just use cora dataset to train and test on real-world PDF papers), as this is significantly different from what other works have done so far. The experimental results have shown sufficient evidence about the feasibility of our proposed method in this aspect.

In light of the urgent threats presented by climate change and rapid urbanisation, interest in ‘smart city systems’ is mounting. In contrast to scholarship that poses ‘smartness’ as something that needs to be added to cities, recent developments in spatial morphology research pursue a view of the built fabric of cities as an extension of the cognitive human apparatus, as well as a material formulation of social, cultural and economic relations and processes. The built fabric of cities needs to be understood as a highly intelligent artefact in itself, rather than simple, dead matter. The current focus on high-tech systems risks concealing the fact that the machine is already there. In contrast to the technological ‘implements’ of smart city systems, this article looks at cities as ‘facilities’ – that is, as technologies that slow down, store and maintain energy as a resource for a variety of purposes. The article builds on space syntax research in order to give precision to the understanding of the affordances the cities offer their various processes and the ways in which cities operate as information storage and retrieval devices for individuals and for society. The city must be considered, we argue, in terms of a range of tangled, interdependent systems, reaching from individual buildings to the whole city, an understanding anchored in notions of ‘diversity’ and ‘density’ (recently gathered under the concept of ‘spatial capital’) and in research addressing how the distribution of space and artefacts serve as means of knowledge communication (specifically, in complex buildings such as libraries and department stores). In conclusion, we argue that existing discussions on ‘smart city systems’ would benefit acknowledgement of the role of cities as facilities.

Purpose – Technical services librarians, catalogers and metadata specialists serve as the integral managers of comprehensive integrated systems designed to facilitate the ingestion, annotation, cataloging, storage, retrieval and distribution of organized, discoverable resources. Yet, despite the escalating costs to upgrade integrated library systems, maintain authority control for name and subject heading points of access and create original surrogate records for new library resources, technical services departments did not grow. Design/methodology/approach – The goal of sharing metadata is to reduce the local cost of its creation with minimal changes. However, research suggests that catalogers and metadata specialists review and authenticate the standards-compliant work of others, thus negating the goal of sharing and increasing the cost of building and maintaining online catalogs and discovery tools. How can a library administrator encourage the acceptance of metadata created at other information organizations and make prudent investments to support technical services functions? Findings – There are four strategies that administrators can adopt regarding these issues. Research limitations/implications – All libraries can benefit from considering the four strategies. Practical implications – First, cultivate a robust community of practice within the information organization. Second, recognize the importance of accepting standards-compliant bibliographic metadata with few modifications. Third, provide opportunities for managers to become skilled at coaching their team members. Fourth, inspire confidence. Social implications – Librarianship is a profession that an individual enters through graduate education in library and information science. As a new entrant, an individual becomes of a member of the community of practice and assumes personal responsibility for learning and mastering technical skills and competencies through experience, mentoring, professional development and continued actions (or tasks) comprising activities situated in a library or information environment. Originality/value – This is an original opinion piece.

The scientific activity of the state archives has been visibly regressing for several years and it has been regarded critically by the archival community. The article outlines the current state of scientific activity of the state archives. The most important problem areas requiring in-depth analysis and a discussion within the archival community have been proposed. The author presented the priority research needs of contemporary archivistics, in which scientific research is essential for the further development of archives. These are: contemporary electronic office and methods of shaping the documents accrual (management of large archival data sets, metadata standards, creation of information retrieval models, selection and evaluation of electronic and mixed documentation, issues of permanent storage of documents created in electronic and hybrid documentation systems); institutional development of state archives (IT systems for fonds management), smart buildings systems for archival buildings, modern methods of preventive maintenance and conservation; archival methodology (boundaries and research tools of contemporary archival methodology, taking into account the diversity of forms and types of documentation). Moreover, the need to undertake interdisciplinary research in the field of digital humanities was indicated, as well as to develop a modern dictionary of terminology of archival science and works developing the principles of editing 20th and 21st century archival sources, taking into account their new digital and Internet forms. Proposals of preferred organizational solutions in the area of scientific activity of archives were discussed, taking into account the new organization of science in Poland resulting from the 2018 reform: establishment of an archival school and a system of academic grants in cooperation with the Association of Polish Archivists.

A Review of: Asher, A. D., Duke, L. M., & Wilson, S. (2012). Paths of discovery: Comparing the search effectiveness of EBSCO Discovery Service, Summon, Google Scholar, and conventional library resources. College & Research Libraries, 74(5), p. 464-488. Objectives – To explore the effectiveness of different search tools (EBSCO Discovery Service (EDS), Summon, Google Scholar and traditional library resources) in supporting the typical research queries faced by undergraduate students and gain an understanding of student research practices. Design – Mixed methods approach using quantitative data collected from grading of students’ selected resources combined with qualitative data from a search process interview with students. Setting – Two university libraries in the United States of America (Bucknell University (BU) and Illinois Wesleyan University (IWU)). Subjects – Eighty-seven undergraduate students across a range of disciplines. Methods – Participants were assigned to one of five test groups and required to find two resources for each of four standardised research queries using a specified tool: EDS; Summon; Google Scholar; Library catalogue/databases; or “no tool” where no specific tool was specified and participants were free to choose. The resources submitted by students for each of the four queries were rated on a scale of 0-3 by four librarians using a rubric, to produce average ratings for each tool. The interview comprised two parts: the search task, followed by a reflective interview based on open-ended questions relating to search practices and habits. The search process interview was recorded using Camtasia screen capture and audio software, and the URLs used by participants were also recorded. Main Results – Quantitative results indicated that students who used EDS selected slightly higher quality sources on average (scoring 2.54 out of 3), compared to all other groups. Those who used EDS also completed the queries in less time (747 seconds) than those using Summon (1,209 seconds), Google Scholar (968 seconds), library databases (963 seconds) or where no tool was specified (1,081 seconds). Academic journal articles also represented the relatively highest proportion of resources for this group (73.8% of resources chosen), whilst newspaper articles were chosen most frequently by those using Summon (20.6% of resources chosen). The qualitative findings suggest that students may over-rely on the top results provided by search systems, rather than using critical analysis and evaluation. Conclusion – Although EDS performed slightly better overall, in some cases the tools produced relatively similar results, and none of the tools performed particularly poorly. Indeed the reasonably strong performance of both Google Scholar and traditional library tools/databases in some aspects (such as the relative proportion of books and journal articles chosen by students), may raise questions regarding the potential benefit of acquiring a new discovery product, given the possibly significant costs involved. As the study finds that most students do not go beyond simple searches and the first page of results, regardless of the tool they are using, this suggests that discovery services do not substantially lessen the need for information literacy instruction, although it may provide some opportunity to redirect teaching time away from retrieval and towards higher-order skills such as evaluating information and critical thinking.

The ultimate result of the merger of the technologies of information systems, broadcasting, and traditional person-to-person telecommunications -- an integrated system -- is already in view, but not so clear are the regulatory [e.g., copyright, electronic carbon copies and postmarks], financial, and commercial/business junctions which will need eventuate. At academic institutions, and particularly so in academic libraries, the "electronic ["digital"] library" will not only maintain the historic role of electronic storage and retrieval but also include "knowledge management" and information delivery roles that have implications in every area of management, services, instruction and research.

Information services offered by academic libraries increasingly rely on assistive technologies (AT) to facilitate disabled patrons’ retrieval and use of information for learning and teaching. However, disabled patrons’ access to AT might not always lead to their use, resulting in the underutilization of information services offered by academic libraries. We adopt an inward-looking, service innovation perspective to improve information services for disabled patrons using AT. The open coding of qualitative responses collected from administrators and librarians in 186 academic libraries in public universities in the United States, reveals 10 mechanisms (i.e. modified work practices), which involve searching, compiling, mixing, framing, sharing, or reusing information, and learning from it. Based on this information-centric reorganisation of work practices, we propose an ‘information value chain’, like Porter’s value chain, for improving information services to disabled patrons using AT in academic libraries, which is the major theoretical contribution of our study.

This study took cognisance of the fact that the term 'knowledge management' lacks a universally accepted definition, and consequently sought to describe the term using the most common co-occurring terms in knowledge management (KM) literature as indexed in the Library, Information Science and Technology Abstracts (LISTA) database. Using a variety of approaches and analytic techniques (e.g. core/periphery analysis and co-occurrence of words as subject terms), data were analysed using the core/periphery model and social networks through UCINET for Windows, TI, textSTAT and Bibexcel computer-aided software. The study identified the following as the compound terms with which KM co-occurs most frequently: information resources management, information science, information technology, information services, information retrieval, library science, management information systems and libraries. The core single subject terms with which KM can be defined include resources, technology, libraries, systems, services, retrieval, storage, data and computers. The article concludes by offering the library and information science (LIS) professionals' general perception of KM based on their use of terms, through which KM can be defined within the context of LIS.

PurposeThis paper reviews literature on the application of intelligent systems in the libraries with a special issue on the ES/AI and Robot. Also, it introduces the potential of libraries to use intelligent systems, especially ES/AI and robots.Design/methodology/approachDescriptive and content review methods are applied, and the researchers critically reviewed the articles related to library ESs and robots from Web of Science as a general database and Emerald as a specific database in library and information science from 2007–2017. Four scopes considered to classify the articles as technology, service, user and resource. It is found that published researches on the intelligent systems have contributed to many librarian purposes like library technical services like the organization of information resources, storage and retrieval of information resources, library public services as reference services, information desk and other purposes.FindingsA review of the previous studies shows that ESs are a useable intelligent system in library and information science that mimic librarian expert’s behaviors to support decision making and management. Also, it is shown that the current information systems have a high potential to be improved by integration with AI technologies. In this researches, librarian robots mostly designed for detection and replacing books on the shelf. Improving the technology of gripping, localizing and human-robot interaction are the main concern in recent librarian robot research. Our conclusion is that we need to develop research in the area of smart resources.Originality/valueThis study has a new approach to the literature review in this area. We compared the published papers in the field of ES/AI and robot and library from two databases, general and specific.

One of the most frequent comments about Internet-based media, particularly about newsgroups and the Web, is that they provide a forum for everyone, no matter how obscure or specific their interest -- you'll find dedicated fora for every field, from high-energy physics to learning Klingon, from the campaign for an independent country in Northern Italy to Indonesian cooking. This is seen as a positive development as often as it is regarded as a negative force -- optimists see these fora as potential bases for the formation of virtual communities which may be able to reinvigorate previously neglected niche groupings, while pessimists predict a further shattering of societies into disparate fragments with mutually almost unintelligible cultural attitudes. Examples supporting either view can be found amongst the multitudes of newsgroups and Websites available on the Net, but let us skip this debate for the moment; instead, let's focus on some of the potential consequences this situation may have for academia. It requires little prescience to predict that the next few years will see an increasing use of the Web and, to a smaller extent, newsgroups in academic teaching and research. Continuously updated Websites will enable students and scholars to work with the latest developments in their disciplines, rather than limiting themselves to whatever recent books and journals their university library has managed to acquire, and newsgroups can help put interested academics in touch with each other in order to exchange news and pointers to information on the Web, as well as discuss recent research. For anyone with a computer, much of this information will also be accessible more easily electronically, via the Internet, than physically through libraries, bookstores, and photocopies. If it is organised efficiently on the Web, interested researchers may also come to be able to better target precisely the information they need, avoiding the need to leaf through volumes of journals to find the one useful article they might contain. Such research isn't limited only to academics and university students anymore, though. As hypertext scholar George P. Landow notes, "hypertext provides the individualistic learner with the perfect means for exploration and enrichment of particular areas of study. By permitting one to move from relatively familiar areas to less familiar ones, a hypertext corpus encourages the autodidact, the continuing education student, and the student with little access to instructors" (Hypertext 129-30) -- particularly the ethos of information freedom that is widespread on the Internet means that any amateur enthusiast may conduct their own self-education with the materials available on the Web. This was already possible, after a fashion, in pre-Web times, of course, but the Net increases the amount of information available, and removes the physical and psychological barrier of entering a university library as a non-student, and facilitates connections to other (self-taught as well as 'official') students through newsgroups and email. What's more, the Web also allows adding one's own voice to academic debates: "in a book one can always move one's finger or pencil across the printed page, but one's intrusion always remains physically separate from the text. One may make a mark on the page, but one's intrusion does not affect the text itself" (Landow, Hypertext 44). By creating a Web page displaying one's own thoughts on the matter, providing links to related sites, and ideally receiving links from those sites, too, any outsider may now invade the discourse in an academic discipline. In most cases, such invasions may go largely unnoticed -- but nothing's to stop a self-taught enthusiast from creating a highly useful Website that even 'proper' academics may consider relevant, and so from adding own articles to the discipline's body of knowledge. As a side-effect of such presentation on the Web, then, texts by students are no longer so easily subordinated to those by revered authors, and disparities between them are less visible. The text as a site of authority can also become a site of resistance: in hypertext, indeed, opposition to the canonised texts is more likely to succeed in conditions of hypertextuality than in the print culture, if only because hypertext makes it easier to expose the contradictions and power moves in such texts, and the multiply constructed positions from which they might be read. (Snyder 77) Both these points pose a major problem for the currently prevalent conventions of academic debate, of course, which (despite post-structuralism's argument for the "death of the author") still evaluate the relevance of academic work partly based on its authorial source. Canonisation of particular scholars and their works (a process which is not limited only to literary disciplines) must ultimately fail -- "because all electronic texts are interrelated, none has well-defined borders; instead, each text reaches out to link up with past, present and future texts. It therefore becomes difficult to cordon off and to canonise a few great texts and authors" (Snyder 75). And generally, Nunberg notes, "media like the Web tend to resist attempts to impose the sort of solutions that enable us to manage (even imperfectly) the steady increase in the number of print documents -- the ramification of discourses and forms of publication, the imposition of systems of screening or refereeing, the restriction of the right to speak to 'qualified' participants" ("Farewell" 126). The freely accessible information on the Web includes texts by revered researchers as well as badly-informed beginners, and elaborate essays as well as superficial scribblings. This realisation has caused many academics who grew up with the apparent simplicities of print to regard Internet-based media with despair and, frequently, with contempt; Nunberg himself provides a good example by stating that "any undergraduate student is free to post her night thoughts on Mary Shelley or the Klingon verb to a 'potential audience' of millions (a quick search of the Web turns up numerous examples of both), and there will be nothing in its mode of circulation to distinguish it from communications from better-qualified contributors" ("Farewell" 127). Such remarkably condescending prose indicates more than anything a paralysing fear of an invasion of the proverbial academic ivory tower by the uncouth hordes of self-taught dilettantes who have no respect for scholarly authority: Nunberg's insistence that a notion of academic 'qualification' (expressed no doubt in degrees and positions) could do any more than indicate vaguely that an author might have something valuable to say, and that anybody not 'qualified' this way cannot possibly contribute anything worth one's while, is surprisingly hierarchistic. Surely, in reality the onus for determining a text's worth should (and must) always eventually lie with the individual reader; the sense a text makes, not the source that made the text, should determine its quality. It's easy to see that this emphasis which Nunberg and others place on a text's source is in fact determined by print as the still-prevalent technology of information dissemination. As Bolter describes it, "the idea of a relatively stable canon made sense in a culture dominated by printed books. ... But the notion of a standard has now collapsed, and the collapse is mirrored in the shift from the printed to the electronic writing space, in which a stable canon of works and authors is meaningless" (237). Landow elaborates that hypertext's effects are so basic, so radical, that it reveals that many of our most cherished, most commonplace ideas and attitudes toward literature and literary production turn out to be the result of that particular form of information technology and technology of cultural memory that has provided the setting for them. This technology -- that of the printed book and of its close relations, which include the typed or printed page -- engenders certain notions of authorial property, authorial uniqueness, and a physically isolated text that hypertext makes untenable. The evidence of hypertext, in other words, historicises many of our most commonplace assumptions, thereby forcing them to descend from the ethereality of abstraction and appear as corollaries to a particular technology rooted in specific times and places. (33) Today, on the Web, however, where anyone can participate by adding their own texts or simply rearranging others', we lose once and for all notions of the author or the text as a stable entity. Thus, Nunberg claims, "on the Web ... you can never have the kind of experience that you can have with the informational genres of print, the experience of interpreting a text simply as a newspaper or encyclopedia article without attending to its author, its publisher, or the reliability of its recommender. We read Web documents, that is, not as information but as intelligence, which requires an explicit warrant of one form or another" ("Farewell" 127-8). Again, however, Nunberg claims a simplicity of the print media which simply doesn't exist: he goes on to say that "we should look to electronic discourse to provide a counter and complement to the informational forms of print -- a domain that privileges the personal, the private, and the subjective against the impersonal, the public, and the objective" (133). In reality, though, anyone who today still reads a newspaper or any other form of printed information as an 'objective' source, without an awareness of its publisher's or its journalists' political and economic agenda, must certainly be regarded as a naïve fool -- not just in Australia, with its atrocious standards of print journalism. If the modern media have taught us anything, it is that there is no such thing as 'objective truth'; the Web, with its unprecedented opportunities for world-wide publication, just makes this fact particularly obvious. While they may contribute to more openness in dealing with contributions from non-traditionally qualified sources, however, such realisations won't completely eradicate academia's fear of an invasion by the self-trained and the untrained. Some hope is at hand, though: "at the very moment indeed when the new technologies of memory can make us fear an alarming glut of traces -- a true change of scale in the collective accumulation of archives, at once written, audio, visual, and audiovisual -- these same technologies increasingly lighten its load, at almost the same pace, by facilitating individualised retrieval" (Debray 146); more elaborate search engines and resource listings on the Web can help point interested researchers to useful contributions both from within and without the ivory tower, and multiple alternative engines and listings may cater for various definitions of what constitutes 'useful'. "In the future, it seems, there will be no fixed canons of texts and no fixed epistemological boundaries between disciplines, only paths of inquiry, modes of integration, and moments of encounter" (Hesse 31). This may also have negative implications, though. On the one hand, as Bazin writes, "the digital empire puts too much emphasis on relation and circulation per se, rather than on the acquisition of content. Instead of the substantialist metaphysics of the hidden meaning which a 'vertical' reading would attempt to reveal, it prefers the rhetoric of exchange and conversation. It counters the aesthetics of depth with a pragmatics of interface" (163-4), and researchers on the Web may stay on the surface of a discipline rather than explore the very depths of its discourse -- they may stick with digests, digest-digests, digest-digest-digests, to borrow from Ray Bradbury (55). "Electronic linking almost inevitably tends to lead to blending and mixing of genres and modes ... . Hypertextualising a text produces not an electronic book but a miniature electronic library" (Landow, "Twenty Minutes" 226-7), and sticking to one's research topic may prove difficult. On the other end of the scale, the Net's tendency to group interests off into niches may lead to specific deeply involved research being done without any awareness of related disciplines that may offer alternative approaches to a subject -- in short, without any knowledge of the bigger picture one's discipline fits into. To avoid both pitfalls demands a researcher's discipline and attention. On the positive side, the invasion of the ivory tower allows for unprecedented public involvement (as Net theorists have often promised it): we are witnessing the appearance ... of a 'dynamic textuality' ... that by freeing itself from the straitjacket of the book is transforming not only the individual's relation to the text but also the traditional model of producing and transmitting learning and practical knowledge. In the place vacated by a linear transmission, inherited from forebears and relatively individualised, a system for the coemergence of bodies of knowledge is tending to be progressively substituted -- a system in which instruction, self-apprenticing, intellectual creation, and diffusion all closely cooperate. (Bazin 163) Naturally, this process won't mean that anybody can now easily become a nuclear scientist, economic expert, or cultural historian -- in most fields, to make it to the very top of the profession will still require a level of access to materials and equipment that only academic and professional institutions can offer. Nonetheless, more self-trained amateur enthusiasts will now be able to make meaningful contributions to their discipline -- a development we already begin to see in fields as diverse as astronomy, computer sciences, and some forms of literary studies. At the very least, it will create among the participants a more interested, more informed and more involved public, thinking for themselves and questioning the commonplaces of a print-based culture. "We are promised ... less of the dogmatic and more of the ludic, less of the canonical and more of the festive. Fewer arguments from authority, though more juxtaposition of authorities" (Debray 146). The invasion of the ivory tower is no attack on the Bastille -- the new dilettante invaders come to learn and share, not to destroy. References Bazin, Patrick. "Toward Metareading." Nunberg 153-68.
