    Abstract
    By the explosion of possibilities for a ubiquitous content production, the information overload problem reaches the level of complexity which cannot be managed by traditional modelling approaches anymore. Due to their pure syntactical nature traditional information retrieval approaches did not succeed in treating content itself (i.e. its meaning, and not its representation). This leads to a very low usefulness of the results of a retrieval process for a user's task at hand. In the last ten years ontologies have been emerged from an interesting conceptualisation paradigm to a very promising (semantic) modelling technology, especially in the context of the Semantic Web. From the information retrieval point of view, ontologies enable a machine-understandable form of content description, such that the retrieval process can be driven by the meaning of the content. However, the very ambiguous nature of the retrieval process in which a user, due to the unfamiliarity with the underlying repository and/or query syntax, just approximates his information need in a query, implies a necessity to include the user in the retrieval process more actively in order to close the gap between the meaning of the content and the meaning of a user's query (i.e. his information need). This thesis lays foundation for such an ontology-based interactive retrieval process, in which the retrieval system interacts with a user in order to conceptually interpret the meaning of his query, whereas the underlying domain ontology drives the conceptualisation process. In that way the retrieval process evolves from a query evaluation process into a highly interactive cooperation between a user and the retrieval system, in which the system tries to anticipate the user's information need and to deliver the relevant content proactively. Moreover, the notion of content relevance for a user's query evolves from a content dependent artefact to the multidimensional context-dependent structure, strongly influenced by the user's preferences. This cooperation process is realized as the so-called Librarian Agent Query Refinement Process. In order to clarify the impact of an ontology on the retrieval process (regarding its complexity and quality), a set of methods and tools for different levels of content and query formalisation is developed, ranging from pure ontology-based inferencing to keyword-based querying in which semantics automatically emerges from the results. Our evaluation studies have shown that the possibilities to conceptualize a user's information need in the right manner and to interpret the retrieval results accordingly are key issues for realizing much more meaningful information retrieval systems.

    Abstract
    Zwei Trends prägen derzeit die Gestalt des Internets: Auf der einen Seite finden sich Entwicklungen rund um das "Web 2.0" oder "Social Web", die dem einzelnen Nutzer neue Möglichkeiten des onlinegestützten Identitäts-, Beziehungs- und Informationsmanagements eröffnen. Auf der anderen Seite stehen die Innovationen des Semantic Web, die Relationen zwischen Datenbeständen strukturieren helfen, um so zu verbesserten maschinellen Repräsentationen von Wissen zu gelangen. Dieser Beitrag skizziert die Idee eines "Social Semantic Web", in dem beide Entwicklungen zusammenfließen. Als Scharnier dient dabei der Begriff der Prodnutzung, der die aktive Rolle des Nutzers bei der Erstellung, Verbreitung und Weiterentwicklung von Inhalten wie von strukturiertem Wissen betont.

    Abstract
    LibraryThing ist eine zur Klasse der Sozialen Software gehörende Webanwendung, in der Benutzer gemeinsam Bücher verwalten und miteinander in Kontakt treten können. Die Webseite wurde Ende August 2005 veröffentlicht und verzeichnet inzwischen (Juli 2007) über 235.000 Benutzer und 16 Millionen verschiedene Bücher. Jeder Nutzer verfügt über eine eigene Sammlung, die in LibraryThing als "Bibliotheken" oder "Katalog" bezeichnet wird. Die Katalogisierung geschieht in eine gemeinsame Datenbank, die von allen Nutzern direkt bearbeitet werden kann. Da es sich um eine reine Webanwendung handelt, muss zur Nutzung keine weitere Software installiert werden. Die Nutzung ist für bis zu 200 Medien kostenlos, eine jährliche Mitgliedschaft kostet 10 $ und eine lebenslange Mitgliedschaft 25 $. Bibliotheken und andere nichtkommerzielle Einrichtungen zahlen 15 $ pro Jahr. Dieses Preismodell hat sich auch nicht geändert, nachdem 40% des Unternehmens im Mai 2006 vom Gebrauchtbuchhändler AbeBooks übernommen wurden. Die Mehrheit hält weiterhin der Gründer Tim Spalding, der die ursprünglich als privates Projekt begonnene Seite mit inzwischen zwei weiteren Entwicklern und einer Bibliothekarin kontinuierlich weiterentwickelt.

    "Vom Nutzer zur Community Wie bei anderen Formen Sozialer Software beruht die Popularität von LibraryThing zu einem großen Teil auf den Interaktionsmöglichkeiten, durch die Nutzer miteinander in Kontakt treten und zusammenarbeiten. Neben einem allgemeinen Forum und Diskussionen zu konkreten Büchern, können sich Nutzer zu Gruppen zusammenschließen, beispielsweise die Comic-Liebhaber in der Gruppe Comics' und die deutschsprachigen LibraryThing-Nutzer in der Gruppe German Library Thingers. Per RSS können Nachrichten zu neuen Teilnehmern, Gruppen und Büchern aus Sammlungen von Gruppenmitgliedern abonniert werden. Jeder Benutzer verfügt über eine Profilseite, auf der er sich anderen Nutzern vorstellen kann und wo diese ihm Nachrichten hinterlassen können. Zu den Einträgen einzelner Nutzer, Werke, Bücher und Autoren wird jeweils angezeigt, welche Nutzer über die gleichen Bücher in ihrer Sammlung verfügen - so bringt LibraryThing Menschen zusammen, die sich für die gleichen Bücher interessieren. Jeder Nutzer kann zudem Bücher auf einer Skala von null bis fünf Sternen bewerten und Rezensionen einstellen. Erschließung leichtgemacht Nutzer können in LibraryThing bereits vorhandene Bücher mit einem Klick in ihre eigene Sammlung aufnehmen oder wieder entfernen. Das so kopierte Katalogisat können sie dann beliebig bearbeiten. Die Bearbeitung erfolgt nach dem Wiki-Prinzip direkt im Webbrowser. Bei der Anzeige einzelner Bücher und Werke werden die verschiedenen Metadaten dann zusammengefasst angezeigt. Andere Inhalte, wie die Autorenseiten (vergleichbar mit Personen-Normdatensätzen), können von allen Nutzern verändert werden. Eine wesentliche Rolle bei der Erschließung spielen freie Schlagwörter (Tags), aber auch DDC-Nummern lassen sich eintragen und werden beim Import aus Bibliothekskatalogen übernommen. Mit knapp 15 Feldern (Tags, Rezension, Bewertung, Titel, Autor, Weitere Autoren, Datum, ISBN, LoC-Signatur, DDC-Nummern, bibliographische Daten, Zusammenfassung, Kommentar und bis zu drei Sprachen) ist die Erschließung noch überschaubar und wird vor allem den Bedürfnissen der Nutzer gerecht.
    Zusammenarbeit mit Bibliotheken Bereits früh setzte sich Tim Spalding für eine Zusammenarbeit mit Bibliotheken ein. Zum Eintragen von neuen Büchern in LibraryThing können zahlreiche Bibliothekskataloge ausgewählt werden, die via Z39.50 eingebunden werden - seit Oktober 2006 ist auch der GBV dabei. Im April 2007 veröffentlichte Tim Spalding mit LibraryThing for Libraries ein Reihe von Webservices, die Bibliotheken in ihre OPACs einbinden können.4 Ein Webservice ist eine Funktion, die von anderen Programmen über das Web aufgerufen werden kann und Daten zurückliefert. Bereits seit Juni 2006 können über verschiedene offene LibraryThing-Webservices unter Anderem zu einer gegebenen ISBN die Sprache und eine Liste von ISBNs anderer Auflagen und Übersetzungen ermittelt werden, die zum gleichen Werk gehören (thinglSBN). Damit setzt LibraryThing praktisch einen Teil der Functional Requirements for Bibliographic Records (FRBR) um, die in bibliothekswissenschaftlichen Fachkreisen bereits seit Anfang der 1990er diskutiert werden, aber bislang nicht so Recht ihre Umsetzung in Katalogen gefunden haben. Die Information darüber, welche Bücher zum gleichen Werk gehören, wird von der LibraryThing-Community bereitgestellt; jeder Benutzer kann einzelne Ausgaben mit einem Klick zusammenführen oder wieder trennen. Vergleiche mit dem ähnlichen Dienst xISBN von OCLC zeigen, dass sich thinglSBN und xISBN gut ergänzen, allerdings bietet LibraryThing seinen Webservice im Gegensatz zu OCLC kostenlos an. Neben Empfehlungen von verwandten Büchern ist es im Rahmen von LibraryThing for Libraries auch möglich, die von den Nutzern vergebenen Tags in den eigenen Katalog einzubinden. Ein Nachteil dabei ist allerdings die bisherige Übermacht der englischen Sprache und dass nur selbständige Titel mit ISBN berücksichtigt werden. Die VZG prüft derzeit, in welcher Form LibraryThing for Libraries am besten in GBV-Bibliotheken umgesetzt werden kann. Es spricht allerdings für jede einzelne Bibliothek nichts dagegen, schon jetzt damit zu experimentieren, wie der eigene OPAC mit zusätzlichen Links und Tags von LibraryThing aussehen könnte. Darüber hinaus können sich auch Bibliotheken mit einem eigenen Zugang als Nutzer in LibraryThing beteiligen. So stellt beispielsweise die Stadtbücherei Nordenham bereits seit Ende 2005 ihre Neuzugänge im Erwachsenenbestand in einer Sammlung bei LibraryThing ein.
    Beispiel für die Anwendung von LibraryThing for Libraries im Katalog des Waterford Institute of Technology (): Zu einer ISBN werden auf Basis der in LibraryThing gesammelten Daten andere Auflagen und Übersetzungen, ähnliche Bücher und Tags eingeblendet. Soziale Software lebt vom Mitmachen Vieles spricht dafür, dass LibraryThing auf dem besten Weg ist, sich zu einem der wichtigsten Web 2.0-Dienste für die Zusammenarbeit mit Bibliotheken zu entwickeln. Wie schon bei Wikipedia gibt es allerdings noch viel zu oft Berührungsängste und die Vorstellung, dass sich diese Dienste erst durch Hilfe von Außen in der eigenen Einrichtung einführen ließen. Soziale Software lebt jedoch von der Zusammenarbeit und dem freien Austausch von Gedanken und Informationen. Deshalb hilft nur eins: Ausprobieren und Mitmachen. Ebenso wie Wikipedia schwer zu beurteilen ist, ohne selbst mit anderen Wikipedianern einen Artikel erstellt und diskutiert zu haben, erschließt sich LibraryThing erst vollständig durch eine eigene dort angelegte Büchersammlung. Zum Kennenlernen reicht der kostenlose Zugang und mit 15 $ Jahresgebühr können auch Bibliotheken problemlos bis zu 5.000 Medieneinheiten pro Sammlung einstellen. Wenn Sie erstmal mehr mit Library-Thing vertraut sind, werden Ihnen sicherlich weitere Einsatzmöglichkeiten für Ihre Einrichtung und deren Nutzer einfallen. LibraryThing entwickelt sich beständig weiter und dürfte noch für einige Überraschungen gut sein.

    Was wäre, wenn der Computer den Inhalt einer Seite aus dem World Wide Web nicht nur anzeigen, sondern auch seine Bedeutung erfassen würde? Er könnte ungeahnte Dinge für seinen Benutzer tun - und das vielleicht schon bald, wenn das semantische Netz etabliert ist

    Abstract
    Bibliografische Daten, Normdaten und Metadaten im Semantic Web - Konzepte der Bibliografischen Kontrolle im Wandel. Der Titel dieser Arbeit zielt in ein essentielles Feld der Bibliotheks- und Informationswissenschaft, die Bibliografische Kontrolle. Als zweites zentrales Konzept wird der in der Weiterentwicklung des World Wide Webs (WWW) bedeutsame Begriff des Semantic Webs genannt. Auf den ersten Blick handelt es sich hier um einen ungleichen Wettstreit. Auf der einen Seite die Bibliografische Kontrolle, welche die Methoden und Mittel zur Erschließung von bibliothekarischen Objekten umfasst und traditionell in Form von formal-inhaltlichen Surrogaten in Katalogen daherkommt. Auf der anderen Seite das Buzzword Semantic Web mit seinen hochtrabenden Konnotationen eines durch Selbstreferenzialität "bedeutungstragenden", wenn nicht sogar "intelligenten" Webs. Wie kamen also eine wissenschaftliche Bibliothekarin und ein Mitglied des World Wide Web Consortiums 2007 dazu, gemeinsam einen Aufsatz zu publizieren und darin zu behaupten, das semantische Netz würde ein "bibliothekarischeres" Netz sein? Um sich dieser Frage zu nähern, soll zunächst kurz die historische Entwicklung der beiden Informationssphären Bibliothek und WWW gemeinsam betrachtet werden. Denn so oft - und völlig zurecht - die informationelle Revolution durch das Internet beschworen wird, so taucht auch immer wieder das Analogon einer weltweiten, virtuellen Bibliothek auf. Genauer gesagt, nahmen die theoretischen Überlegungen, die später zur Entwicklung des Internets führen sollten, ihren Ausgangspunkt (neben Kybernetik und entstehender Computertechnik) beim Konzept des Informationsspeichers Bibliothek.

    Abstract
    Während in den vergangenen Monaten Themen wie Web 2.0 und Social Software ein erstaunliches Konjunkturhoch erlebt haben, vollzieht sich weitgehend abseits der öffentlichen Wahrnehmung eine technologische Komplementärinnovation. Die wachsende Adaption semantischer Technologien zu Zwecken der strukturierten Erschließung von "Web 2.0 Content", aber auch der Einsatz von Social Software zur kollaborativen Anreicherung von Web Content mit maschinenlesbaren Metadaten sind Ausdruck eines Trends in Richtung "Social Semantic Web". Bezeichnendes Merkmal dieser Entwicklung ist die voranschreitende Konvergenz zwischen Social Software und Semantic Web Technologien. Dieser Beitrag hat das Ziel ein allgemeines Bewusstsein und Verständnis dieser Entwicklung zu schaffen und nähert sich dem Phänomen aus einer nichttechnischen Perspektive.

    Abstract
    Das Semantic Web - bzw. Linked Data - hat das Potenzial, die Verfügbarkeit von Daten und Wissen, sowie den Zugriff darauf zu revolutionieren. Einen großen Beitrag dazu können Wissensorganisationssysteme wie Thesauri leisten, die die Daten inhaltlich erschließen und strukturieren. Leider sind immer noch viele dieser Systeme lediglich in Buchform oder in speziellen Anwendungen verfügbar. Wie also lassen sie sich für das Semantic Web nutzen? Das Simple Knowledge Organization System (SKOS) bietet eine Möglichkeit, die Wissensorganisationssysteme in eine Form zu "übersetzen", die im Web zitiert und mit anderen Resourcen verknüpft werden kann.

    Abstract
    Das Medium Internet ist im Wandel, und mit ihm ändern sich seine Publikations- und Rezeptionsbedingungen. Welche Chancen bieten die momentan parallel diskutierten Zukunftsentwürfe von Social Web und Semantic Web? Zur Beantwortung dieser Frage beschäftigt sich der Beitrag mit den Grundlagen beider Modelle unter den Aspekten Anwendungsbezug und Technologie, beleuchtet darüber hinaus jedoch auch deren Unzulänglichkeiten sowie den Mehrwert einer mediengerechten Kombination. Am Beispiel des grammatischen Online-Informationssystems grammis wird eine Strategie zur integrativen Nutzung der jeweiligen Stärken skizziert.

    Abstract
    We have created software applications that allow users to both author and use Semantic Web metadata. To create and use a layer of semantic content on top of the existing Web, we have (1) implemented a user interface that expedites the task of attributing metadata to resources on the Web, and (2) augmented a Web browser to leverage this semantic metadata to provide relevant information and tasks to the user. This project provides a framework for annotating and reorganizing existing files, pages, and sites on the Web that is similar to Vannevar Bushrsquos original concepts of trail blazing and associative indexing.

    Abstract
    One vision of the Semantic Web is that it will be much like the Web we know today, except that documents will be enriched by annotations in machine understandable markup. These annotations will provide metadata about the documents as well as machine interpretable statements capturing some of the meaning of document content. We discuss how the information retrieval paradigm might be recast in such an environment. We suggest that retrieval can be tightly bound to inference. Doing so makes today's Web search engines useful to Semantic Web inference engines, and causes improvements in either retrieval or inference to lead directly to improvements in the other.

    Abstract
    More and more cultural heritage institutions publish their collections, vocabularies and metadata on the Web. The resulting Web of linked cultural data opens up exciting new possibilities for searching and browsing through these cultural heritage collections. We report on ongoing work in which we investigate the estimation of relevance in this Web of Culture. We study existing measures of semantic distance and how they apply to two use cases. The use cases relate to the structured, multilingual and multimodal nature of the Culture Web. We distinguish between measures using the Web, such as Google distance and PMI, and measures using the Linked Data Web, i.e. the semantic structure of metadata vocabularies. We perform a small study in which we compare these semantic distance measures to human judgements of relevance. Although it is too early to draw any definitive conclusions, the study provides new insights into the applicability of semantic distance measures to the Web of Culture, and clear starting points for further research.

    Abstract
    This chapter presents ontologies and their role in the creation of the Semantic Web. Ontologies hold special interest, because they are very closely related to the way we understand the world. They provide common understanding, the very first step to successful communication. In following sections, we will present ontologies, how they are created and used. We will describe available tools for specifying and working with ontologies.

    Abstract
    First generation scholarly research on the Web lacked a firm system of authority control. Second generation Web research is beginning to model subject access with library science principles of bibliographic control and cataloguing. Harnessing the Web and organising the intellectual content with standards and controlled vocabulary provides precise search and retrieval capability, increasing relevance and efficient use of technology. Dublin Core metadata standards permit a full evaluation and cataloguing of Web resources appropriate to highly specific research needs and discovery. Current research points to a type of structure based on a system of faceted classification. This system allows the semantic and syntactic relationships to be defined. Controlled vocabulary, such as the Library of Congress Subject Headings, can be assigned, not in a hierarchical structure, but rather as descriptive facets of relating concepts. Web design features such as this are adding value to discovery and filtering out data that lack authority. The system design allows for scalability and extensibility, two technical features that are integral to future development of the digital library and resource discovery.

    Abstract
    Library catalogues contain an enormous amount of structured, high-quality data, however, this data is generally not made available to semantic web applications. In this paper we describe the tools and techniques used to make the Swedish Union Catalogue (LIBRIS) part of the Semantic Web and Linked Data. The focus is on links to and between resources and the mechanisms used to make data available, rather than perfect description of the individual resources. We also present a method of creating links between records of the same work.

    Abstract
    Indexing consists of both novel and more traditional techniques. Cutting-edge indexing techniques, such as automatic indexing, ontologies, and topic maps, were developed independently of older techniques such as thesauri, but it is now recognized that these older methods also hold expertise. Indexing describes various traditional and novel indexing techniques, giving information professionals and students of library and information sciences a broad and comprehensible introduction to indexing. This title consists of twelve chapters: an Introduction to subject readings and theasauri; Automatic indexing versus manual indexing; Techniques applied in automatic indexing of text material; Automatic indexing of images; The black art of indexing moving images; Automatic indexing of music; Taxonomies and ontologies; Metadata formats and indexing; Tagging; Topic maps; Indexing the web; and The Semantic Web.
