Domain-specific track CLEF 2005: Overview of results and approaches, remarks on the assessment analysis

The challenge of the CLEF domain-specific track is to map user queries in one language to documents in different languages adapting the systems used to the vocabulary and wording of the social science domain. In addition to a general overview of this track and its tasks, some details on the approaches of the participating groups and their results are reported. One of the outcomes is the considerable improvement in results if the retrieval systems make use of the thesauri provided or the intellectually assigned descriptors. Other findings for IR in a domain-specific context are also given. Finally, considerations on the topic creation and assessment processes are made on the basis of empirical data mainly from the GIRT corpus.
