- Abstract
- Im Jahr 1995 entstand in interdisziplinärer Zusammenarbeit der Prototyp Bücherschatz, ein Bibliotheks-Online_katalog für Kinder. Beteiligt waren Studierende und eine Professorin der FH Hamburg, Fb Bibliothek und Information, ein Designer und 2 Informatikerinnen der Universität Hamburg. In diesem Bericht werden sowohl das Produkt Bücherschatz als auch der Prozeß seiner Entwicklung beschrieben. Ein Schwerpunkt liegt in der Auseinandersetzung mit theoretischen Modellen der Softwaretechnik - hier STEPS und Prototyping - und ihrer Anpassung an konkrete Projekterfordernisse. Weiterhin werden Fragen nach der Gestaltung kindgerechter Software, der Organisation eines großen Projektteams und nach der Art der Partizipation der Benutzer thematisiert. Das Gesamtprojekt wird in einen wissenschaftlichen Kontext der Informatik eingeordnet, und zentrale Erfahrungen und Erkenntnisse hinsichtlich interdisziplinärer und partizipativer Softwareentwicklung werden zusammengefaßt

- Abstract
- In der folgenden Studie wird eine Komponente für eine visuelle Benutzerschnittstelle zu Textdatenbanken entworfen. Mit Hilfe einer Terminologievisualisierung wird dem Benutzer eine Hilfestellung bei der Relevanzbewertung von Dokumenten und bei der Erweiterung seiner visuellen Anfrage an das Retrieval-System gegeben. Dazu werden zuerst die grundlegenden Information-Retrieval-Modelle eingehender vorgestellt, d.h., generelle Retrieval-Modelle, Retrievaloperationen und spezielle Retrieval-Modelle wie Text-Retrieval werden erläutert. Die Funktionalität eines Text-Retrieval-Systems wird vorgestellt. Darüber hinaus werden bereits existierende Implementierungen visueller Information-Retrieval-Benutzerschnittstellen vorgestellt. Im weiteren Verlauf der Arbeit werden mögliche Visualisierungen der mit Hilfe eines Text-Retrieval-Systems gefundenen Dokumente aufgezeigt. Es werden mehrere Vorschläge zur Visualisierung von Thesauri diskutiert. Es wird gezeigt, wie neuronale Netze zur Kartierung eines Eingabebereiches benutzt werden können. Klassifikationsebenen einer objekt-orientierten Annäherung eines Information-Retrieval-Systems werden vorgestellt. In diesem Zusammenhang werden auch die Eigenschaften von Thesauri sowie die Architektur und Funktion eines Parsersystems erläutert. Mit diesen Voraussetzung wird die Implementierung einer visuellen Terminologierunterstützung realisiert. Abschließend wird ein Fazit zur vorgestellten Realisierung basierend auf einem Drei-Schichten-Modell von [Agosti et al. 1990] gezogen.

- Abstract
- Over the past 50 years, a variety of language-related capabilities has been developed in machine translation, information retrieval, speech recognition, text summarization, and so on. These applications rest upon a set of core techniques such as language modeling, information extraction, parsing, generation, and multimedia planning and integration; and they involve methods using statistics, rules, grammars, lexicons, ontologies, training techniques, and so on. It is a puzzling fact that although all of this work deals with language in some form or other, the major applications have each developed a separate research field. For example, there is no reason why speech recognition techniques involving n-grams and hidden Markov models could not have been used in machine translation 15 years earlier than they were, or why some of the lexical and semantic insights from the subarea called Computational Linguistics are still not used in information retrieval.
This picture will rapidly change. The twin challenges of massive information overload via the web and ubiquitous computers present us with an unavoidable task: developing techniques to handle multilingual and multi-modal information robustly and efficiently, with as high quality performance as possible. The most effective way for us to address such a mammoth task, and to ensure that our various techniques and applications fit together, is to start talking across the artificial research boundaries. Extending the current technologies will require integrating the various capabilities into multi-functional and multi-lingual natural language systems. However, at this time there is no clear vision of how these technologies could or should be assembled into a coherent framework. What would be involved in connecting a speech recognition system to an information retrieval engine, and then using machine translation and summarization software to process the retrieved text? How can traditional parsing and generation be enhanced with statistical techniques? What would be the effect of carefully crafted lexicons on traditional information retrieval? At which points should machine translation be interleaved within information retrieval systems to enable multilingual processing?

- Abstract
- If one follows any of the major cataloging or library blogs these days, it is obvious that the topic of FRBR (Functional Requirements for Bibliographic Records) has increasingly become one of major significance for the library community. What began as a proposed conceptual entity-relationship model for improving the structure of bibliographic records has become a hotly debated topic with many tangled threads that have implications not just for cataloging but for many aspects of libraries and librarianship. In the fall of 2005, the Perseus Project experimented with creating a FRBRized catalog for its current online classics collection, a collection that consists of several hundred classical texts in Greek and Latin as well as reference works and scholarly commentaries regarding these works. In the last two years, with funding from the Mellon Foundation, Perseus has amassed and digitized a growing collection of classical texts (some as image books on our own servers that will eventually be made available through Fedora), and some available through the Open Content Alliance (OCA)2, and created FRBRized cataloging data for these texts. This work was done largely as an experiment to see the potential of the FRBR model for creating a specialized catalog for classics.
Our catalog should not be called a FRBR catalog perhaps, but instead a "FRBR Inspired catalog." As such our main goal has been "practical findability," we are seeking to support the four identified user tasks of the FRBR model, or to "Search, Identify, Select, and Obtain," rather than to create a FRBR catalog, per se. By encoding as much information as possible in the MODS and MADS records we have created, we believe that useful searching will be supported, that by using unique identifiers for works and authors users will be able to identify that the entity they have located is the desired one, that by encoding expression level information (such as the language of the work, the translator, etc) users will be able to select which expression of a work they are interested in, and that by supplying links to different online manifestations that users will be able to obtain access to a digital copy of a work. This white paper will discuss previous and current efforts by the Perseus Project in creating a FRBRized catalog, including the cataloging workflow, lessons learned during the process and will also seek to place this work in the larger context of research regarding FRBR, cataloging, Library 2.0 and the Semantic Web, and the growing importance of the FRBR model in the face of growing million book digital libraries.

- Abstract
- Dieses Whitepaper befasst sich mit der Integration semantischer Technologien in bestehende Ansätze des Information Retrieval und die damit verbundenen weitreichenden Auswirkungen auf Effizienz und Effektivität von Suche und Navigation in Dokumenten. Nach einer Einbettung in die Problematik des Wissensmanagement aus Sicht der Informationstechnik folgt ein Überblick zu den Methoden des Information Retrieval. Anschließend werden die semantischen Technologien "Wissen modellieren - Ontologie" und "Neues Wissen ableiten - Inferenz" vorgestellt. Ein Integrationsansatz wird im Folgenden diskutiert und die entstehenden Mehrwerte präsentiert. Insbesondere ergeben sich Erweiterungen hinsichtlich einer verfeinerten Suchunterstützung und einer kontextbezogenen Navigation sowie die Möglichkeiten der Auswertung von regelbasierten Zusammenhängen und einfache Integration von strukturierten Informationsquellen. Das Whitepaper schließt mit einem Ausblick auf die zukünftige Entwicklung des WWW hin zu einem Semantic Web und die damit verbundenen Implikationen für semantische Technologien.

- Abstract
- Presents the findings of the South Ayrshire Libraries OPen Learning and the Internet project, Sep 1997 to Oct 1998. The objective was to demonstrate how open learning materials available on the Internet could be integrated with the provision of local open learning resources to provide an enhanced learning environment in public libraries. The main areas of concentration within the project were information skills support to public library users and the provision of WWW based independent materials to learners. The organisation and retrieval of Web based resources for local use was a major issue throughout the project. Recommends the adoption of Dublin Core metadata standards, the connection of databases of resources with searchable wen pages, and the development of thesauri of terms used to index the Web based resources locally. Sstaff training, and the new skills which will need to be developed, were identified as issues. Cost was also identified as a related issue, extending to issues such as access to open learning material and the Internet

- Abstract
- Report of a project commissioned by British Library Research and Development Department (BLRDD) from Electronic Publishing Services Ltd designed to provide factual input about electronic publishing in the UK for a worlking party convened by the British Library as part of a follow up to the Information 2000 exercise, completed in 1991. The working party will consider the possible impacts on the library community of the development of electronic publishing. For the purpose of this study, electronic publishing was defined as including: online services (including videotex); magnetic tape services; magnetic disk products; CD-ROM and other optical disc products; ROM cards; and electronic periodicals. The main conclusions were: that the dominant position of Reuters and other financial information services means that online information retrieval still accounts for the vast majority of electronic publishing revenues; that CD-ROM is experiencing high growth, but growth from a small base and coming later than predicted; that network publishing is still in the experimental stage and almost entirely funded from the public sector; that ROM cards, which provide the medium for hand held electronic reference books are still present in the market and represent the only mass market channel; and that other electronic media (magnetic tape, magnetic disk, analogue videodisc) are not seen as having a significant part to play

- Abstract
- In der heutigen Zeit nimmt die Flut an Informationen exponentiell zu. In dieser »Informationsexplosion« entsteht täglich eine unüberschaubare Menge an neuen Informationen im Web: Beispielsweise 430 deutschsprachige Artikel bei Wikipedia, 2,4 Mio. Tweets bei Twitter und 12,2 Mio. Kommentare bei Facebook. Während in Deutschland vor einigen Jahren noch Google als nahezu einzige Suchmaschine beim Zugriff auf Informationen im Web genutzt wurde, nehmen heute die u.a. in Social Media veröffentlichten Meinungen und damit die Vorauswahl sowie Bewertung von Informationen einzelner Experten und Meinungsführer an Bedeutung zu. Aber wie können themenspezifische Informationen nun effizient für konkrete Fragestellungen identifiziert und bedarfsgerecht aufbereitet und visualisiert werden? Diese Studie gibt einen Überblick über semantische Standards und Formate, die Prozesse der semantischen Suche, Methoden und Techniken semantischer Suchsysteme, Komponenten zur Entwicklung semantischer Suchmaschinen sowie den Aufbau bestehender Anwendungen. Die Studie erläutert den prinzipiellen Aufbau semantischer Suchsysteme und stellt Methoden der semantischen Suche vor. Zudem werden Softwarewerkzeuge vorgestellt, mithilfe derer einzelne Funktionalitäten von semantischen Suchmaschinen realisiert werden können. Abschließend erfolgt die Betrachtung bestehender semantischer Suchmaschinen zur Veranschaulichung der Unterschiede der Systeme im Aufbau sowie in der Funktionalität.

- Abstract
- After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

- Abstract
- The aim of the CATRIONA (Cataloguing and Retrieval of Information over Networks Applications) feasibility study was to investigate the technical, organizational and financial requirements for the development of applications software and procedures to enable the cataloguing, calssification and retrieval of documents and other resources over networks such as the Internet. The CATRIONA feasibility study demonstrated that the idea of a distributed catalogue of Internet resources integrated with standard Z39.50 library system OPAC interfaces is already a practical proposition at its most basic level. Proposes that the next step should be a distributed CATRIONA demonstrator project, based on the Scottish University and Research Libraries (SCURL) group of libraries cooperating to catalogue local electronic resources and selected areas of BUBL Subject Trees, but also sufficiently 'open' to encompass other sites, projects and approaches

- Abstract
- The need for improved semantic in teroperability between and among vocabularies and knowledge organization schemes is undeniable and growing in importance. There is an ever-increasing need to create an environment by which even multiple portals could be accessed via subject metadata using software that is neutral and available ubiquitously or directly to the user, that could be copied by libraries for use in their own environment. In order to develop or improve a knowledge organization system including emerging options in semantic interoperability, scholars and practitioners need to be able to evaluate a wide variety of projects and stay current with the professional literature. Based on its findings, the Subcommittee concludes that the development of a successful subject semantic interoperability project is a long and difficult process. It requires a substantial investment of financial, human and computer resources. The Subcommittee recommends using the information and tools in this report and its appendices to assist in developing a successful project incorporating subject semantic interoperability. Finally the Subcommittee concludes that since this field of endeavor is still relatively young and immature, it is too early to generate a set of Best Practices that could be used in developing a successful project. We are past the theoretical and basic research phase and into the development phase. Even though there are some successful projects in full production, more projects need to reach maturity and much more research needs to be done.

- Abstract
- Die rasanten Veränderungen der Kommunikation und der daraus resultierende soziale und kulturelle Wandel betreffen auch die Hochschulen in besonderer Weise. Hochschulleitungen haben hier bereits schon reagiert, sie stehen aber weiterhin vor der Herausforderung, auf die Veränderungen zu reagieren und entsprechende Maßnahmen zu ergreifen. Es bedarf nicht nur einer Harmonisierung des Informationsmanagements und der Informationsinfrastruktur, sondern integrativ auch der Stärkung der Informationskompetenz auf allen Ebenen der Organisation. Da diese Herausforderung das gesamte System Hochschule betrifft, wird der Begriff der Informationskompetenz hier gegenüber seiner herkömmlichen Verwendung deutlich ausgeweitet: Es wird nicht nur die akademische Informationskompetenz betrachtet, die in Lehre und Forschung zum Tragen kommt, sondern auch die organisationsbezogene Informationskompetenz, die sich auf alle hochschulinternen Abläufe bezieht. Zugleich geht es in der Empfehlung nicht, wie es der Titelbegriff "Hochschule im digitalen Zeitalter" nahe legen könnte, um Konzepte wie das einer Netzhochschule.

- Abstract
- Virtuelle Bibliotheken enthalten eine Fülle an Informationen, die in ihrer Vielfalt und Tiefe von Standardsuchmaschinen nicht erschöpfend erfasst wird. Der Arbeitsbericht informiert über Entwicklungen am IZ, die darauf abzielen, Wissen über das Interaktionsgeschehen in wissenschaftlichen Communities und den sozialen Status ihrer Akteure für das Retrieval auszunutzen. Grundlage hierfür sind soziale Netzwerke, die sich durch Kooperation der wissenschaftlichen Akteure konstituieren und in den Dokumenten der Datenbasis z.B. als Koautorbeziehungen repräsentiert sind (Autorennetzwerke). Die in dem Bericht beschriebenen Studien zur Small-World-Topologie von Autorennetzwerken zeigen, dass diese Netzwerke ein erhebliches Potential für Informationssysteme haben. Der Bericht diskutiert Szenarios, die beschreiben, wie Autorennetzwerke und hier insbesondere das Konzept der Akteurszentralität für die Informationssuche in Datenbanken sinnvoll genutzt werden können. Kernansatz dieser Retrievalmodelle ist die Suche nach Experten und das Ranking von Dokumenten auf der Basis der Zentralität von Autoren in Autorennetzwerken.

- Abstract
- Describes the final phase of the work on the ELINOR (Electronic Library INformation Online Retrieval) project at De Montfort University, Leicester, which concluded in 1996. ELINOR was 2 phase project with 3 overall goals: to create a practical pilot system based on a commercial product (Excalibur EFS); to investigate the expansion of a small scale electronic library to a larger, distributed library system; and to develop a more efficient and effective means of accessing and sharing resources within a networked multi campus institution. ELINOR was successful in demonstrating that libraries may conveniently digitize and supply smal collections of high demand materials over a campus network in text anf TIFF format. Operational conditions have so far indicated that the barriers are not technological but involve copyright, use issues and sustainability

- Abstract
- The future of bibliographic control will be collaborative, decentralized, international in scope, and Web-based. Its realization will occur in cooperation with the private sector, and with the active collaboration of library users. Data will be gathered from multiple sources; change will happen quickly; and bibliographic control will be dynamic, not static. The underlying technology that makes this future possible and necessary-the World Wide Web-is now almost two decades old. Libraries must continue the transition to this future without delay in order to retain their relevance as information providers. The Working Group on the Future of Bibliographic Control encourages the library community to take a thoughtful and coordinated approach to effecting significant changes in bibliographic control. Such an approach will call for leadership that is neither unitary nor centralized. Nor will the responsibility to provide such leadership fall solely to the Library of Congress (LC). That said, the Working Group recognizes that LC plays a unique role in the library community of the United States, and the directions that LC takes have great impact on all libraries. We also recognize that there are many other institutions and organizations that have the expertise and the capacity to play significant roles in the bibliographic future. Wherever possible, those institutions must step forward and take responsibility for assisting with navigating the transition and for playing appropriate ongoing roles after that transition is complete. To achieve the goals set out in this document, we must look beyond individual libraries to a system wide deployment of resources. We must realize efficiencies in order to be able to reallocate resources from certain lower-value components of the bibliographic control ecosystem into other higher-value components of that same ecosystem. The recommendations in this report are directed at a number of parties, indicated either by their common initialism (e.g., "LC" for Library of Congress, "PCC" for Program for Cooperative Cataloging) or by their general category (e.g., "Publishers," "National Libraries"). When the recommendation is addressed to "All," it is intended for the library community as a whole and its close collaborators.
The Library of Congress must begin by prioritizing the recommendations that are directed in whole or in part at LC. Some define tasks that can be achieved immediately and with moderate effort; others will require analysis and planning that will have to be coordinated broadly and carefully. The Working Group has consciously not associated time frames with any of its recommendations. The recommendations fall into five general areas: 1. Increase the efficiency of bibliographic production for all libraries through increased cooperation and increased sharing of bibliographic records, and by maximizing the use of data produced throughout the entire "supply chain" for information resources. 2. Transfer effort into higher-value activity. In particular, expand the possibilities for knowledge creation by "exposing" rare and unique materials held by libraries that are currently hidden from view and, thus, underused. 3. Position our technology for the future by recognizing that the World Wide Web is both our technology platform and the appropriate platform for the delivery of our standards. Recognize that people are not the only users of the data we produce in the name of bibliographic control, but so too are machine applications that interact with those data in a variety of ways. 4. Position our community for the future by facilitating the incorporation of evaluative and other user-supplied information into our resource descriptions. Work to realize the potential of the FRBR framework for revealing and capitalizing on the various relationships that exist among information resources. 5. Strengthen the library profession through education and the development of metrics that will inform decision-making now and in the future. The Working Group intends what follows to serve as a broad blueprint for the Library of Congress and its colleagues in the library and information technology communities for extending and promoting access to information resources.

- Abstract
- W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users
