    Abstract
    Der vollständige Projektname von Renardus lautet "Academic Subject Gateway Service Europe". Renardus wird von der Europäischen Union im 5. Rahmenprogramm mit dem Schwerpunktthema "Information Society Technologies" im zweiten Thematischen Programm "Benutzerfreundliche Informationsgesellschaft" ('Promoting a User-friendly Information Society') gefördert. Die Projektlaufzeit ist von Januar 2000 bis Juni 2002. Insgesamt zwölf Partner (Principal und Assistant Contractors) aus Finnland, Dänemark, Schweden, Großbritannien, den Niederlanden, Frankreich und Deutschland beteiligen sich an diesem Projekt. Die Europäische Union unterstützt das Projekt mit 1,7 Mio. EURO, die Gesamtkosten belaufen sich inklusive der Eigenbeteiligungen der Partner auf 2,3 Mio. EURO. Das Ziel des Projektes Renardus ist es, über eine Schnittstelle Zugriff auf verteilte Sammlungen von "High Quality" Internet Ressourcen in Europa zu ermöglichen. Diese Schnittstelle wird über den Renardus Broker realisiert, der das "Cross-Searchen" und "Cross-Browsen" über verteilte "Quality-Controlled Subject Gateways" ermöglicht. Ein weiteres Ziel von Renardus ist es, Möglichkeiten von "metadata sharing" zu evaluieren und in kleinen Experimenten zwischen z. B. Subject Gateways und Nationalbibliothek zu testen bzw. zu realisieren

    Abstract
    As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed

    Abstract
    Die Sonderfördermaßnahme CARMEN (Content Analysis, Retrieval and Metadata: Effective Networking) zielt im Rahmen des vom BMB+F geförderten Programms GLOBAL INFO darauf ab, in der heutigen dezentralen Informationsweit geeignete Informationssysteme für die verteilten Datenbestände in Bibliotheken, Fachinformationszentren und im Internet zu schaffen. Diese Zusammenführung ist weniger technisch als inhaltlich und konzeptuell problematisch. Heterogenität tritt beispielsweise auf, wenn unterschiedliche Datenbestände zur Inhaltserschließung verschiedene Thesauri oder Klassifikationen benutzen, wenn Metadaten unterschiedlich oder überhaupt nicht erfasst werden oder wenn intellektuell aufgearbeitete Quellen mit in der Regel vollständig unerschlossenen Internetdokumenten zusammentreffen. Im Projekt CARMEN wird dieses Problem mit mehreren Methoden angegangen: Über deduktiv-heuristische Verfahren werden Metadaten automatisch aus Dokumenten generiert, außerdem lassen sich mit statistisch-quantitativen Methoden die unterschiedlichen Verwendungen von Termen in den verschiedenen Beständen aufeinander abbilden, und intellektuell erstellte Crosskonkordanzen schaffen sichere Übergänge von einer Dokumentationssprache in eine andere. Für die Extraktion von Metadaten gemäß Dublin Core (v. a. Autor, Titel, Institution, Abstract, Schlagworte) werden anhand typischer Dokumente (Dissertationen aus Math-Net im PostScript-Format und verschiedenste HTML-Dateien von WWW-Servern deutscher sozialwissenschaftlicher Institutionen) Heuristiken entwickelt. Die jeweilige Wahrscheinlichkeit, dass die so gewonnenen Metadaten korrekt und vertrauenswürdig sind, wird über Gewichte den einzelnen Daten zugeordnet. Die Heuristiken werden iterativ in ein Extraktionswerkzeug implementiert, getestet und verbessert, um die Zuverlässigkeit der Verfahren zu erhöhen. Derzeit werden an der Universität Osnabrück und im InformationsZentrum Sozialwissenschaften Bonn anhand mathematischer und sozialwissenschaftlicher Datenbestände erste Prototypen derartiger Transfermodule erstellt
