- Abstract
- Information Retrieval hat sich zu einer Schlüsseltechnologie in der Wissensgesellschaft entwickelt. Die Anzahl der täglichen Anfragen an Internet-Suchmaschinen bildet nur einen Indikator für die große Bedeutung dieses Themas. Der Sammelbandband informiert über Themen wie Information Retrieval-Grundlagen, Retrieval Systeme, Digitale Bibliotheken, Evaluierung und Multilinguale Systeme, beschreibt Anwendungsszenarien und setzt sich mit neuen Herausforderungen an das Information Retrieval auseinander. Die Beiträge behandeln aktuelle Themen und neue Herausforderungen an das Information Retrieval. Die intensive Beteiligung der Informationswissenschaft der Universität Hildesheim am Cross Language Evaluation Forum (CLEF), einer europäischen Evaluierungsinitiative zur Erforschung mehrsprachiger Retrieval Systeme, berührt mehrere der Beiträge. Ebenso spielen Anwendungsszenarien und die Auseinandersetzung mit aktuellen und praktischen Fragestellungen eine große Rolle.

- Abstract
- Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

- Abstract
- Proceedings of the llth TREC-conference held in Gaithersburg, Maryland (USA), November 19-22, 2002. Aim of the conference was discussion an retrieval and related information-seeking tasks for large test collection. 93 research groups used different techniques, for information retrieval from the same large database. This procedure makes it possible to compare the results. The tasks are: Cross-language searching, filtering, interactive searching, searching for novelty, question answering, searching for video shots, and Web searching.
