    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.

    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.

    Abstract
    This poster explores the customization of DSpace to allow the use of the AGRIS Application Profile metadata standard and the AGROVOC thesaurus. The objective is the adaptation of DSpace, through the least invasive code changes either in the form of plug-ins or add-ons, to the specific needs of the Agricultural Sciences and Technology community. Metadata standards such as AGRIS AP, and Knowledge Organization Systems such as the AGROVOC thesaurus, provide mechanisms for sharing information in a standardized manner by recommending the use of common semantics and interoperable syntax (Subirats et al., 2007). AGRIS AP was created to enhance the description, exchange and subsequent retrieval of agricultural Document-like Information Objects (DLIOs). It is a metadata schema which draws from Metadata standards such as Dublin Core (DC), the Australian Government Locator Service Metadata (AGLS) and the Agricultural Metadata Element Set (AgMES) namespaces. It allows sharing of information across dispersed bibliographic systems (FAO, 2005). AGROVOC68 is a multilingual structured thesaurus covering agricultural and related domains. Its main role is to standardize the indexing process in order to make searching simpler and more efficient. AGROVOC is developed by FAO (Lauser et al., 2006). The customization of the DSpace is taking place in several phases. First, the AGRIS AP metadata schema was mapped onto the metadata DSpace model, with several enhancements implemented to support AGRIS AP elements. Next, AGROVOC will be integrated as a controlled vocabulary accessed through a local SKOS or OWL file. Eventually the system will be configurable to access AGROVOC through local files or remotely via webservices. Finally, spell checking and tooltips will be incorporated in the user interface to support metadata editing. Adapting DSpace to support AGRIS AP and annotation using the semantically-rich AGROVOC thesaurus transform DSpace into a powerful, domain-specific system for annotation and exchange of bibliographic metadata in the agricultural domain.

    Abstract
    Platforms for social computing connect users via shared references to people with whom they have relationships, events attended, places lived in or traveled to, and topics such as favorite books or movies. Since free text is insufficient for expressing such references precisely and unambiguously, many social computing platforms coin identifiers for topics, places, events, and people and provide interfaces for finding and selecting these identifiers from controlled lists. Using these interfaces, users collaboratively construct a web of links among entities. This model needn't be limited to social networking sites. Understanding an item in a digital library or museum requires context: information about the topics, places, events, and people to which the item is related. Students, journalists and investigators traditionally discover this kind of context by asking "the four Ws": what, where, when and who. The DCMI Kernel Metadata Community has recognized the four Ws as fundamental elements of descriptions (Kunze & Turner, 2007). Making better use of metadata to answer these questions via links to appropriate contextual resources has been our focus in a series of research projects over the past few years. Currently we are building a system for enabling readers of any text to relate any topic, place, event or person mentioned in the text to the best explanatory resources available. This system is being developed with two different corpora: a diverse variety of biographical texts characterized by very rich and dense mentions of people, events, places and activities, and a large collection of newly-scanned books, journals and manuscripts relating to Irish culture and history. Like a social computing platform, our system consists of tools for referring to topics, places, events or people, disambiguating these references by linking them to unique identifiers, and using the disambiguated references to provide useful information in context and to link to related resources. Yet current social computing platforms, while usually amenable to importing and exporting data, tend to mint proprietary identifiers and expect links to be traversed using their own interfaces. We take a different approach, using identifiers from both established and emerging naming authorities, representing relationships using standardized metadata vocabularies, and publishing those representations using standard protocols so that links can be stored and traversed anywhere. Central to our strategy is to move from appearances in a text to naming authorities to the the construction of links for searching or querying trusted resources. Using identifiers from naming authorities, rather than literal values (as in the DCMI Kernel) or keys from a proprietary database, makes it more likely that links constructed using our system will continue to be useful in the future. WorldCat Identities URIs (http://worldcat.org/identities/) linked to Library of Congress and Deutsche Nationalbibliothek authority files for persons and organizations and Geonames (http://geonames.org/) URIs for places are stable identifiers attached to a wealth of useful metadata. Yet no naming authority can be totally comprehensive, so our system can be extended to use new sources of identifiers as needed. For example, we are experimenting with using Freebase (http://freebase.com/) URIs to identify historical events, for which no established naming authority currently exists. Stable identifiers (URIs), standardized hyperlinked data formats (XML), and uniform publishing protocols (HTTP) are key ingredients of the web's open architecture. Our system provides an example of how this open architecture can be exploited to build flexible and useful tools for connecting resources via shared references to topics, places, events, and people.

    Abstract
    In den Jahren 2002 bis 2007 wurde beim Bundesinstitut für Berufsbildung ein Wissensmanagement-System ("Kommunikations- und Informationssystem Berufliche Bildung") als Portallösung für die deutsche Berufsbildungsforschung aufgebaut. Zentrales Element hierbei ist eine Wissenslandkarte mit rund 1.000 dokumentierten Forschungsprojekten und Themen. Die Autoren zeigen am Beispiel der Literaturdatenbank Berufliche Bildung, wie auf der Basis eines Klassifizierungssystems verschiedene Formen der Wissensrepräsentation kombiniert werden und über die Vernetzung digitaler Informationen in einer gemeinsamen informationstechnologischen Infrastruktur auf verschiedenen Ebenen eine Wertschöpfungskette im Sinne von Linked Data entsteht.

    Abstract
    From the beginning it was understood that the success of the Semantic Web hinges on integrating the vast amount of data stored in Relational Databases. This manuscript reflects on the last 10 years of our research results to integrate Relational Databases with the Semantic Web. Since 2007, our research has led us to answer the following question: How and to what extent can Relational Databases be Integrated with the Semantic Web? The answer comes in two parts. We start by presenting how to get from Relational Databases to the Semantic Web via mappings, such as the W3C Direct Mapping and R2RML standards. Subsequently, we present how the Semantic Web can access Relational Databases. We finalize with how Relational Databases and Semantic Web technologies are being used practice for data integration and discuss open challenges.

    Abstract
    A new model is proposed to retrieve information by building automatically a semantic metatext structure for texts that allow searching and extracting discourse and semantic information according to certain linguistic categorizations. This paper presents approaches for searching and mining full text with semantic categories. The model is built up from two engines: The first one, called EXCOM (Djioua et al., 2006; Alrahabi, 2010), is an automatic system for text annotation, related to discourse and semantic maps, which are specification of general linguistic ontologies founded on the Applicative and Cognitive Grammar. The annotation layer uses a linguistic method called Contextual Exploration, which handles the polysemic values of a term in texts. Several 'semantic maps' underlying 'point of views' for text mining guide this automatic annotation process. The second engine uses semantic annotated texts, produced previously in order to create a semantic inverted index, which is able to retrieve relevant documents for queries associated with discourse and semantic categories such as definition, quotation, causality, relations between concepts, etc. (Djioua & Desclés, 2007). This semantic indexation process builds a metatext layer for textual contents. Some data and linguistic rules sets as well as the general architecture that extend third-party software are expressed as supplementary information.
