Monolingual Retrieval Experiments with a Domain-Specific Document Corpus at the Chemnitz Technical University

چکیده
Abstr act This article describes the first participation of the Media Informatics Section of the Chemnitz Technical University at the Cross Language Evaluation Forum. A first experimental prototype is described which implements several different methods of optimizing search results. The configuration of the prototype is tested with the GIRT corpus. The results of the DomainSpecific Monolingual German task suggest that combining the suffix stripping stemming and the decompounding approach is very useful. Also, a local document clustering approach used to improve pseudo relevance feedback seems to be quite beneficial. Nevertheless, the evaluation of the English task using the same configuration suggests that the qualities of the results are highly speech dependent.

The Importance of being Grid: Chemnitz University of Technology at Grid@CLEF
This paper describes the participation of the Chemnitz University of Technology at Grid@CLEF 2009. We integrated the CIRCO framework into our Xtrieval framework and performed 15 runs in the three languages German, English, and French. For each language we used two different stemmers and two different retrieval models. One run one was a fusion run combining the results of the four other experime...

This paper reports on our participation in CLEF 2005‘s domain-specific retrieval track. The experiments were based on previous experiences with the GIRT document corpus and were run in parallel to the multi-lingual experiments for CLEF 2005. We optimized the parameters of the system with one corpus from 2004 and applied these settings to the domain specific task. In that manner, the robustness ...
