“…Contrary to standard query expansion techniques, the new terms form a second query and results of both initial and second query are integrated under a logistic fusion strategy. The Daedalus group submitted experiments with the Miracle system [35]; BM25 weighting without blind relevance feedback was applied. For detailed descriptions of all the robust experiments, see the Robust section in these Proceedings.…”

Abstract. We describe the objectives and organization of the CLEF 2007 Ad Hoc track and discuss the main characteristics of the tasks offered to test monolingual and cross-language textual document retrieval systems. The track was divided into two streams. The main stream offered mono-and bilingual tasks on target collections for central European languages (Bulgarian, Czech and Hungarian). Similarly to last year, a bilingual task that encouraged system testing with non-European languages against English documents was also offered; this year, particular attention was given to Indian languages. The second stream, designed for more experienced participants, offered mono-and bilingual "robust" tasks with the objective of privileging experiments which achieve good stable performance over all queries rather than high average performance. These experiments re-used CLEF test collections from previous years in three languages (English, French, and Portuguese). The performance achieved for each task is presented and discussed.

Abstract. We describe the objectives and organization of the CLEF 2005 ad hoc track and discuss the main characteristics of the tasks offered to test monolingual, bilingual, and multilingual textual document retrieval. The performance achieved for each task is presented and a statistical analysis of results is given. The mono-and bilingual tasks followed the pattern of previous years but included target collections for two new-to-CLEF languages: Bulgarian and Hungarian. The multilingual tasks concentrated on exploring the reuse of existing test collections from an earlier CLEF campaign. The objectives were to attempt to measure progress in multilingual information retrieval by comparing the results for CLEF 2005 submissions with those of participants in earlier workshops, and also to encourage participants to explore multilingual list merging techniques.
