    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
    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
    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
    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
    Finding particular documents after they have been reviewed and stored has been a challenge since the advent of the printed word. "Findability" is emphatically more important as we deal with information overload in general and with the specific need to quickly find relevant background information to support business decisions in a networked environment. Because time is arguably the most valuable asset in today's economy, information users value tools that help them (1) quickly find the information they are seeking and (2) manage the quantity and quality of information they manipulate and work with on a regular basis. Although the term "indexing" may lack the cachet of some other terms we use to describe current information organization and management concepts, indexing is fundamental to precise information organization and retrieval, especially when dealing with large sets of documents. Power users find great value in using a known, granular indexing language that can surface the most relevant items and filter out items of peripheral or no interest. Web architects and interface designers can likewise take advantage of indexing labels to present only the information meeting certain requirements for users who do not wish to learn the indexing structure or taxonomy. The user finds what is needed while the indexing language is used behind the scenes and is transparent to the user.
    The importance of indexing in developing a content navigation strategy for corporate intranets or portals and the value of high-quality indexing when retrieving information from external resources are reviewed in this white paper. Some general background information on indexing and the use of controlled vocabularies (or taxonomies) are included for a historical perspective. Factiva Intelligent Indexing-which incorporates the best indexing expertise from both Dow Jones Interactive and Reuters Business Briefing-is described, along with some novel customer applications that take advantage of Factiva's indexing to create or improve information products delivered to users. Examples from the Excite and Google web search engines and from Dow Jones Interactive and Reuters Business Briefing are included in an Appendix section to illustrate how indexing influences the amount and quality of information retrieved in a specific search.

    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
    Seit Bestehen der Menschheit sammelt der Mensch Informationen, seit Bestehen des Internets stellt der Mensch Informationen ins Web, seit Bestehen des Semantic Webs sollen auch Maschinen in die Lage versetzt werden mit diesen Informationen umzugehen. Das Bibliothekswesen ist einer der Sammler. Seit Jahrhunderten werden Kataloge und Bibliografien sowie Inventarnachweise geführt. Mit der Aufgabe des Zettelkatalogs hin zum Onlinekatalog wurde es Benutzern plötzlich möglich in Beständen komfortabel zu suchen. Durch die Bereitstellung von Daten aus dem Bibliothekswesen im Semantic Web sollen nicht nur die eigenen Katalogsysteme Zugriff auf diese Informationen erhalten, sondern jede beliebige Anwendung, die auf das Web zugreifen kann. Darüber hinaus ist die Vorstellung, dass sich die im Web befindenden Daten - in sofern möglich - miteinander verlinken und zu einem gigantischen semantischen Netz werden, das als ein großer Datenpool verwendet werden kann. Die Voraussetzung hierfür ist wie beim Übergang zum Onlinekatalog die Aufbereitung der Daten in einem passenden Format. Normdaten dienen im Bibliothekswesen bereits dazu eine Vernetzung der unterschiedlichen Bestände zu erlauben. Bei der Erschließung eines Buches wird nicht bloß gesagt, dass jemand, der Thomas Mann heißt, der Autor ist - es wird eine Verknüpfung vom Katalogisat zu dem Thomas Mann erzeugt, der am 6. Juni 1875 in Lübeck geboren und am 12. August 1955 in Zürich verstorben ist. Der Vorteil von Normdateneintragungen ist, dass sie zum eindeutigen Nachweis der Verfasserschaft oder Mitwirkung an einem Werk beitragen. Auch stehen Normdateneintragungen bereits allen Bibliotheken für die Nachnutzung bereit - der Schritt ins Semantic Web wäre somit die Öffnung der Normdaten für alle denkbaren Nutzergruppen.
    Die Gemeinsame Normdatei (GND) ist seit April 2012 die Datei, die die im deutschsprachigen Bibliothekswesen verwendeten Normdaten enthält. Folglich muss auf Basis dieser Daten eine Repräsentation für die Darstellung als Linked Data im Semantic Web etabliert werden. Neben der eigentlichen Bereitstellung von GND-Daten im Semantic Web sollen die Daten mit bereits als Linked Data vorhandenen Datenbeständen (DBpedia, VIAF etc.) verknüpft und nach Möglichkeit kompatibel sein, wodurch die GND einem internationalen und spartenübergreifenden Publikum zugänglich gemacht wird. Dieses Dokument dient vor allem zur Beschreibung, wie die GND-Linked-Data-Repräsentation entstand und dem Weg zur Spezifikation einer eignen Ontologie. Hierfür werden nach einer kurzen Einführung in die GND die Grundprinzipien und wichtigsten Standards für die Veröffentlichung von Linked Data im Semantic Web vorgestellt, um darauf aufbauend existierende Vokabulare und Ontologien des Bibliothekswesens betrachten zu können. Anschließend folgt ein Exkurs in das generelle Vorgehen für die Bereitstellung von Linked Data, wobei die so oft zitierte Open World Assumption kritisch hinterfragt und damit verbundene Probleme insbesondere in Hinsicht Interoperabilität und Nachnutzbarkeit aufgedeckt werden. Um Probleme der Interoperabilität zu vermeiden, wird den Empfehlungen der Library Linked Data Incubator Group [LLD11] gefolgt.
    Im Kapitel Anwendungsprofile als Basis für die Ontologieentwicklung wird die Spezifikation von Dublin Core Anwendungsprofilen kritisch betrachtet, um auszumachen wann und in welcher Form sich ihre Verwendung bei dem Vorhaben Bereitstellung von Linked Data anbietet. In den nachfolgenden Abschnitten wird die GND-Ontologie, welche als Standard für die Serialisierung von GND-Daten im Semantic Web dient, samt Modellierungsentscheidungen näher vorgestellt. Dabei wird insbesondere der Technik des Vocabulary Alignment eine prominente Position eingeräumt, da darin ein entscheidender Mechanismus zur Steigerung der Interoperabilität und Nachnutzbarkeit gesehen wird. Auch wird sich mit der Verlinkung zu externen Datensets intensiv beschäftigt. Hierfür wurden ausgewählte Datenbestände hinsichtlich ihrer Qualität und Aktualität untersucht und Empfehlungen für die Implementierung innerhalb des GND-Datenbestandes gegeben. Abschließend werden eine Zusammenfassung und ein Ausblick auf weitere Schritte gegeben.

    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
    In 2000, Factiva published "The Value of Indexing," a white paper emphasizing the strategic importance of accurate categorization, based on a robust taxonomy for later retrieval of documents stored in commercial or in-house content repositories. Since that time, there has been resounding agreement between persons who use Web-based systems and those who design these systems that search engines alone are not the answer for effective information retrieval. High-quality categorization is crucial if users are to be able to find the right answers in repositories of articles and documents that are expanding at phenomenal rates. Companies continue to invest in technologies that will help them organize and integrate their content. A March 2002 article in EContent suggests a typical taxonomy implementation usually costs around $100,000. The article also cites a Merrill Lynch study that predicts the market for search and categorization products, now at about $600 million, will more than double by 2005. Classification activities are not new. In the third century B.C., Callimachus of Cyrene managed the ancient Library of Alexandria. To help scholars find items in the collection, he created an index of all the scrolls organized according to a subject taxonomy. Factiva's parent companies, Dow Jones and Reuters, each have more than 20 years of experience with developing taxonomies and painstaking manual categorization processes and also have a solid history with automated categorization techniques. This experience and expertise put Factiva at the leading edge of developing and applying categorization technology today. This paper will update readers about enhancements made to the Factiva Intelligent IndexingT taxonomy. It examines the value these enhancements bring to Factiva's news and business information service, and the value brought to clients who license the Factiva taxonomy as a fundamental component of their own Enterprise Knowledge Architecture. There is a behind-the-scenes-look at how Factiva classifies a huge stream of incoming articles published in a variety of formats and languages. The paper concludes with an overview of new Factiva services and solutions that are designed specifically to help clients improve productivity and make solid business decisions by precisely finding information in their own everexpanding content repositories.

    Abstract
    The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

    Abstract
    Das vorliegende Werk ist der erste Band in der Reihe "Branchenreports" der Semantic Web School. Diese Reihe, die in Zusammenarbeit mit Branchenexperten entwickelt wurde, verfolgt das Ziel, in regelmäßigen Abständen die Bedeutung semantischer Technologien in ausgewählten Branchen und Communities zu analysieren und zu durchleuchten. Damit sollen dem interessierten Leser in erster Linie ein Überblick und Einstiegspunkte geboten werden: Die Branchenreports helfen, sich in einem emergenten Umfeld besser orientieren zu können, sie zeigen Entwicklungspfade an, entlang welcher sich Branchen bewegen, die vermehrt auf den Einsatz semantischer Informationstechnologien setzen. Dieser Branchenreport beschäftigt sich mit dem Bibliotheks-, Informationsund Dokumentationswesen (BID) und es ist kein Zufall, dass diese Branche als erste durchleuchtet wird, sind doch hier die Wurzeln der professionellen Wissensorganisation zu finden. Nun, im Zeitalter der Digitalisierung und des Internets, steht diese Community vor neuen, großen Herausforderungen und Möglichkeiten. Gerade im Umfeld des Semantic Web zeigt sich, dass die Erfahrungen aus dem BID-Bereich einen wichtigen Beitrag leisten können, soll die Entwicklung des Internets der nächsten Generation nicht nur von der Technik geprägt werden. Dieser Band möchte die Neugierde all jener wecken, die sich vor neuen Technologien nicht verschließen, und darauf aufmerksam machen, dass die Möglichkeiten, Information und Wissen zu organisieren, im 21. Jahrhundert gänzlich neue sein werden.

    Rez. in: Mitt VÖB 60(2007)H.3, S.80-81 (J. Bertram): "Wie aus dem Titel der Publikation hervorgeht, will der Autor eine Bestandsaufnahme zum Einsatz semantischer Technologien im BID-Bereich (Bibliothek - Information - Dokumentation) bzw. BAM-Bereich (Bibliothek - Archiv - Museum) vornehmen. einigem Befremden, dass eines von insgesamt drei Vorwörtern für ein einschlägiges Softwareprodukt wirbt und von einer Firmenmitarbeiterin verfasst worden ist. Nach einer Skizze des gegenwärtigen Standes nationaler und europäischer Bibliothekspolitik folgen kurze Definitionen zu den beteiligten Branchen, zu semantischen Technologien und zu Precision und Recall. Die Ausführungen zu semantischen Technologien hätten durchaus gleich an den Anfang gestellt werden können, schließlich sollen sie ja das Hauptthema der vorliegenden Publikation abgeben. Zudem hätten sie konkreter, trennschärfer und ausführlicher ausfallen können. Der Autor moniert zu Recht das Fehlen einer einheitlichen Auffassung, was unter semantischen Technologien denn nun genau zu verstehen sei. Seine Definition lässt allerdings Fragen offen. So wird z.B. nicht geklärt, was besagte Technologien von den hier auch immer wieder erwähnten semantischen Tools unterscheidet. Das nachfolgende Kapitel über bibliographische Tools vereint eine Aufzählung konkreter Beispiele für Austauschformate, Dokumentationssysteme, Suchmaschinen, Informationsportale und OPACs. Im Anschluss daran stellt der Autor Methoden semantischer Anreicherung (bibliographischer) Daten vor und präsentiert Projekte im Bibliotheksbereich. Der aufzählende Charakter dieses und des vorangestellten Kapitels mag einem schnellen Überblick über die fraglichen Gegenstände dienlich sein, für eine systematische Lektüre eignen sich diese Passagen weniger. Auch wird der Bezug zu semantischen Technologien nicht durchgängig hergestellt.
    Danach kommt das Werk - leider nur auf acht Seiten - zu seinem thematischen Kern. Die Frage, ob, in welchem Ausmaß und welche semantischen Technologien im BID-%BAM-Bereich eingesetzt werden, sollte eigentlich mit einer schriftlichen Befragung einschlägiger Institutionen verfolgt werden. Jedoch konnte dieses Ziel wegen des geringen Rücklaufs nur sehr eingeschränkt erreicht werden: im ersten Versuch antworteten sechs Personen aus insgesamt 65 angeschriebenen Institutionen. Beim zweiten Versuch mit einem deutlich abgespeckten Fragekatalog kamen weitere fünf Antworten dazu. Ausschlaggebend für die geringe Resonanz dürfte eine Mischung aus methodischen und inhaltlichen Faktoren gewesen sein: Eine schriftliche Befragung mit vorwiegend offenen Fragen durchzuführen, ist ohnehin schon ein Wagnis. Wenn diese Fragen dann auch noch gleichermaßen komplex wie voraussetzungsvoll sind, dann ist ein unbefriedigender Rücklauf keine Überraschung. Nicht zuletzt mag sich hier die Mutmaßung des Autors aus seinem Vorwort bewahrheiten und ihm zugleich zum Verhängnis geworden sein, nämlich dass "der Begriff 'Semantik' vielen Bibliothekaren und Dokumentaren noch nicht geläufig (ist)" - wie sollen sie dann aber Fragen dazu beantworten? Beispielhaft sei dafür die folgende angeführt: "Welche Erwartungen, Perspektiven, Prognosen, Potentiale, Paradigmen verbinden Sie persönlich mit dem Thema ,Semantische Technologien'?" Am Ende liegt der Wert der Untersuchung sicher vor allem darin, eine grundlegende Annahme über den Status quo in der fraglichen Branche zu bestätigen: dass semantische Technologien dort heute noch eine geringe Rolle und künftig schon eine viel größere spielen werden. Insgesamt gewinnt man den Eindruck, dass hier zum Hauptgegenstand geworden ist, was eigentlich nur Rahmen sein sollte. Die Publikation (auch der Anhang) wirkt streckenweise etwas mosaiksteinartig, das eigentlich Interessierende kommt zu kurz. Gleichwohl besteht ihr Verdienst darin, eine Annäherung an ein Thema zu geben, das in den fraglichen Institutionen noch nicht sehr bekannt ist. Auf diese Weise mag sie dazu beitragen, semantische Technologien im Bewusstsein der beteiligten Akteure stärker zu verankern. Das hier besprochene Werk ist der erste Band einer Publikationsreihe der Semantic Web School zum Einsatz semantischer Technologien in unterschiedlichen Branchen. Den nachfolgenden Bänden ist zu wünschen, dass sie sich auf empirische Untersuchungen mit größerer Resonanz stützen können."
