Abstract

Ziel des Socio-Guide Projektes am Informationszentrum Sozialwissenschaften war die prototypische Entwicklung eines Fachinformationssystems für den Nachweis sozialwissenschaftlich relevanter Dokumente im World-Wide-Web. Es wurde eine datenbankbasierte Anwendung mit WWW-Interface erstellt, die dem Besucher sowohl das Browsen, als auch die gezielte Suche in den intellektuell kategorisierten Beständen erlaubt. Besonderes Augenmerk wurde auf Werkzeuge zur Aktualisierung und Wartung der Datenbestände gelegt, da die referenzierten Dokumente im Intemet sich ständig ändern können. Weiterhin wurden Workflow-Konzepte eingearbeitet, um die verteilte Bearbeitung und Verwaltung der Datenbestände durch verschiedene Mitarbeiter und externe Zuarbeiter zu ermöglichen

Abstract

Clearinghouses - or subject gateways - are domain-specific collections of links to resources an the Internet. The links are described with metadata and structured according to a domain-specific subject hierarchy. Users access the information by searching in the metadata or by browsing the subject hierarchy. The standards for metadata vary across existing Clearinghouses and different technologies for storing and accessing the metadata are used. This makes it difficult to distribute the editorial or administrative work involved in maintaining a clearinghouse, or to exchange information with other systems. DBClear is a generic, platform-independent clearinghouse system, whose metadata schema can be adapted to different standards. The data is stored in a relational database. It includes a workflow component to Support distributed maintenance and automation modules for link checking and metadata extraction. The presentation of the clearinghouse an the Web can be modified to allow seamless integration into existing web sites.

Abstract

Nowadays, users of information services are faced with highly decentralised, heterogeneous document sources with different content analysis. Semantic heterogeneity occurs e.g. when resources using different systems for content description are searched using a simple query system. This report describes several approaches of handling semantic heterogeneity used in projects of the German Social Science Information Centre
