The thesis main goal is to suggest an innovative model for electronic web-based journals in the research field of classical studies and, in particular, of classical philology. In Italy, Humanities suffer some delay in the adoption of digital technologies with regard to publishing in scientific journals. However this delay could be avoided by taking advantage of the results obtained in the past recent years by projects started within other disciplines, in particular within physics and maths. The first chapter discusses the effects of the Web on scientific communication systems such as the journal crisis, the appearance of initiatives in collaborative writing (e.g. Wikipedia) and the Open Access Movement. In the second chapter the main specifics of the Classical Literature and Philology field have been identified in order to outline the requirements of an e-journal model which can solve existing problems with the use of electronic resources for research purposes. The third chapter is dedicated to the illustration of the implementation of the project development. In conclusion, the implemented prototype of an e-journal on classical philology highlighted how suitable the text encoding using an XML-compliant format is in order to provide scholars reading on-line publications with advanced features and value added services. Although the manual deep encoding of huge quantities of documents (journal articles, books, commentaries) is a task too expensive to perform with regard to both time and human resources necessary. Therefore it is need to develop in the next future some tools for the automatic extraction of semantic data from large corpora of unstructured discipline-specific texts.

This dissertation is focused on new email user interfaces that may improve awareness and handling of task-laden messages in the inbox. The practical motivation for this research was to help email users process messages more effectively.Two user studies were conducted to test hypothesized benefits of the new visual representations and to examine the effects of different levels of selected cognitive abilities on task-laden message handling performance. Task performance on both of the new visual interfaces was faster than on the more traditional textual interfaces, but only when finding date-related information. Selected cognitive abilities were found to impact different dependent measures. Working memory and flexibility of closure had effects on performance time, while visual memory and working memory had effects on user interactions involving manipulation of the visual field, such as scrolling and sorting.A field study was conducted to examine email practices related to handling messages that refer to pending tasks. Individual differences in message handling style were observed, with one group of users transferring such messages out of their email programs to other applications (e.g., calendars), while the other group kept prospective messages in email and used the inbox as a reminder of future events.This research contributes to understanding interactions among cognitive abilities, user interfaces and tasks. These interactions are essential for developing two types of interface: inclusive interfaces that work for users with a wide range of cognitive abilities, and personalized and adaptive interfaces that are fitted to individual characteristics.Two novel graphical user interfaces were designed to facilitate monitoring and retrieval of prospective information from email messages. The TaskView interface displayed task-laden messages on a two-dimensional grid (with time on the horizontal axis). The WebTaskMail interface retained the two-dimensional grid, but extended the representation of pending tasks (added distinction between events and to-do's with deadlines), a vertical date reading line, and more space for email message headers.

Subject of this thesis is the user interface Blended Shelf, which provides a shelf browsing experience beyond the physical location of the library. Shelf browsing offers numerous advantages and users apply it as a research strategy in libraries. Little usable and proven applications exist to provide shelf browsing in the digital domain, which would allow time and location independent shelf access for the users. Therefore, the aim of this work is to develop a user interface, which offers the experience of digital shelf browsing, without losing the essential advantages that are deeply rooted in the physical space. To accomplish this, the first part of the thesis constructs a collection of basic requirements that need to be fulfilled to emulate the shelf browsing experience. The basics of these requirements are the theoretical background of shelf browsing, as well as an analysis of library specific aspects and user needs. The central parts of the work illustrate how the usage of the requirement collection serves as a foundation for the concrete implementation, the set of functions and the reality-based interaction design of Blended Shelf. Finally, an evaluation in form of a comprehensive field study checks whether the implementation meets the requirements and if the users perceive the User Interface as useful and usable. A description and discussion of the study design and results forms the last third of the thesis. An outlook to and discussion of open questions and future work concludes the thesis.

Taking libraries as "technologies of intelligence" the author develops a reflection where tradicional library is "opposed" to its virtual counterpart. Models of information retrieval are discussed within the two mentioned models of libraries. New virtual concepts as "navigation" or "surfing" are compared with those present in more traditional information retrieval systems, as "the best match". Here are some other opposite concepts discussed: fuzzy set theory opposed to boolean logic; the interrelation between the basis of information technology and the development of information retrieval tools are also under scrutinity. At last, it discusses the specificity of hypermidia environment which poses new questions to the development of Information Retrieval Theory. The radical differences perceived between tradicional and virtual libraries does not leads the author to a polarization when considering the future. Although digitalization is an irreversible tendency related to information world, the author concludes by the complementarity of the two models of libraries.

Information is an intrinsic element to human relations. When transmitted or stored in digital media, it needs to be well described so it can be efficiently retrieved, accessed and interpreted by society. Among the themes of interest to society today, agrobiodiversity is a broad concept that involves organisms and ecosystems related to agricultural production and crops. For computational systems, the representation of information produced about agrobiodiversity can be done with metadata. However, the existing metadata standards do not fully include the representation of some concepts of agrobiodiversity, as in the Darwin Core (DwC) standard. The aim of this research was to present principles for the creation of an extension of metadata for the DwC standard, having as scope the ecological interactions in the context of agrobiodiversity. To achieve the research aim, the methodology, characterized as exploratory, qualitative, applied and descriptive, was divided into two stages: 1) exploration of methodological and terminological inputs; 2) terminological definition and metadata modeling. The execution of the first stage of the methodology was organized into four substeps: a) systematic analysis of the literature on ecological interactions; b) analysis of the main core of DwC terms; c) analysis of the extensions to the DwC metadata standard; d) correlated terminological analysis of the classes of the model , DwC and concepts of ecological interactions. The first substep resulted in a conceptual model on ecological interactions; the second substep resulted in the translation of the definitions of the terms of the main core of the DwC and respective analyzes; the third substep presented a summary of the content of the metadata extensions developed for DwC in other projects; and, finally, the fourth substep consisted of analyzing in a correlated manner the classes of the model, which was developed by Embrapa in order to organize information on agrobiodiversity, the DwC term classes and their extensions and the conceptual model of ecological interactions. The second stage of the methodology resulted in three metadata elements, created to represent the interaction of parasitism, represented as a metadata record in Extensible Markup Language (XML). It is considered that the greatest contribution of this research was to present a set of methodological principles for the creation of an extension of metadata for the representation of ecological interactions in the context of agrobiodiversity, which can foster improvements in agricultural practices, which are important for the entire community. society, as well as for the field of information science studies.

The document management system of the IVAC, implemented over a full-text DBMS, is not able to properly register data of film copies filed in each of its records. It neither allows to navigate simultaneously through different types of item. In this paper the causes of the problem are analysed; and it has been designed a procedure involving data extraction, analysis, and conversion to a relational database, which will allow to represent data accurately. The designed procedure is easy to be repeated. The result is a web application for consulting filmographic fund.

The purpose of this work is to provide understanding regarding the future of library workplaces by, first, establishing the relationship between Joseph Campbell's functions of mythology in traditional cultures and workplace texts, and then showing libraries as workplaces with such texts. With this framework in place, it is possible to pick-out the fundamental cycle inherent in library workplace cosmology, highlight pedagogical cycles inherent in library texts, and generate an informed understanding of future cosmological and pedagogical trends using educated extrapolation of such cycles. These steps all serve to lay further groundwork in understanding library workplace mythology and its sociological effects, and, using the relationship between ever-moving cosmological and pedagogical cycles, it becomes possible to form an educated picture of future library sociology. In the end, library workplace mythology has no new revelations about the direction of library workplace sociology, only new ways of dispelling predictions often made about the future of libraries and their workplaces. By looking at library workplaces as sites of mythology, this work offers expectations that the same cycles inherent in past and present library workplaces will continue to overcome changes in the technological, political, and social constructs of future library workplaces.

The possible emigration of users of the website to any of the new communication channels is based on easier access to the library's services, as they are offered via tools and applications that are already used by the audience. Moreover, the link between library and users is strengthened, as the audience's needs are totally covered, thus creating a feeling of loyalty to the library. It should also be borne in mind that the large number of such channels gives a wider public access to the library's services in a shorter time, contributing to virality. And in general the institution's visibility and reputation in the web ecosystem are enhanced. As part of the process of constructing the on-line brand of Spanish university libraries, the services they offer can be identified under a unified banner in an environment where the growing use of mobile devices facilitates simultaneous access via various channels. However, this means our objectives both for the web services offered and the development of the on-line brand need to be associated with this identity, while the library in question must avoid becoming lost among all the content offered by competitors. This research is intended to show the need for Spanish university libraries to create an on-line brand, in the light of the possible existence of a linear correlation between the increase in the use of certain web environments (social media, apps and specific tools, which can only be viewed on mobile devices), as indicated by appropriate metrics, and the decrease in the use of the website tool, also measurable in this way. It also aims to compare the influence of tactical objectives such as popularity, activity, social perception, commitment and conversion on the possible increase in the use of these web environments and the possible decrease in the use of the website. This quantitative descriptive research proposes to compile information on the number of Spanish university libraries for which the tactical objectives of popularity, activity, social perception, commitment and conversion are pursued more effectively in the above web environments than via the website, when promoting the visibility of the libraries and their brand identity. We also try to predict, using simple regression analysis, whether the increase in the number of libraries where the use of web environments is growing coincides with an increase in the number of libraries where the use of the website is decreasing. Of the possible combinations between the website and each of the web environments analysed, the variables giving the highest Pearson linear correlation coefficient were the number of libraries where the use of each of the web tools grew and the number of libraries the use of whose website decreased. There was a strong positive correlation as both increased in parallel. Using the tabulated data for both variables, and in order to verify the prediction, in the regression formula: , the variable x, (number of libraries where the number of visits to each of the web environments increased) was replaced by a random value in the range between the minimum and maximum tabulated values for both variables. The process was carried out with two values in order to obtain two pairs of data (x, y), which were used as coordinates, so that results falling on the regression line for these data would confirm the hypothesis of an increase in both variables, as was the case. To verify the validity of the prediction line in the regression equation, the value of the variable x was replaced by its average, giving the average value of the variable y as a result. When these two values were added to the regression line, the point at which they met also fell on the line. Finally the coefficient of determination was measured, with a view to confirming that the variable for the number of libraries where the use of each of the web tools increased accounted for the variable for the number of libraries where the use of the website decreased in almost 100% of cases. One of the conclusions of this research is that it confirms the prediction that a greater increase in the number of Spanish university libraries using REBIUN where the number of accesses or visits to the website between 2004 and 2012 inclusive fell matches a greater increase in the number of Spanish university libraries using REBIUN where the number of visits and downloads using the web environments analysed in the same period rose. The results for Popularity, Influence, Commitment and Conversion were considered neutral, as it was not possible to establish a greater or lesser predominance for these indicators in relation to the web environments analysed compared to the website. However, the result for Activity showed a higher level of influence with the web environments than in the case of the website.

Subject of this diploma thesis are portal solutions for the presentation of electronic collections, including a market review and criteria for the acquisition decision from heilbronn business school´s point of view. In this thesis the heilbronn business school is presented and relevant basic conditions for the implementation of a portal solution are considered. Within the second part, the thesis focuses on the analysis of the term „portal“ and points out the features and elements of portal solutions. In the following the results of an interview with comparable universities are presented and a market review, introducing portal vendors and their portal solutions, is presented. Important aspects for the acquisition of a portal solution, relating to heilbronn business school´s perspective, are developed in the last part of the thesis. Finally an acquisition recommendation is given.

The study examines preconditions to adopt semantic web technologies for a novel specialized medium of scholarly communication that – also interdisciplinary – enables the synchronicity of publication and knowledge representation on the one hand and the dynamic bundling of assertions on the other hand. Therefore it is first of all necessary to determine a concept of „(scholarly) publication“ and of neighbouring concepts. These considerations are fertilized by theories that can be related to the radical constructivism. Therefrom derives a critique of the mainstream of knowledge representation that resigns to being not able to represent the dynamics of knowledge. Finally the study evinces a conceptual outline of a technical system that is built upon the known concept of nanopublications and is called „scholarly network“. The increased effort while publishing in the scholarly network is outweighed by the benefits of this publication medium: It may help to render research outputs more precisely as well as to raise their connectivity through reducing the complexity of assertions. Beyond that it would generate an openly accessible and finely structured discourse archive – a wide participation provided.
