Logistic Regression for Metadata: Cheshire Takes on Adhoc-TEL. Since the Adhoc-TEL task is new for this year, we took the approach of using methods that have performed fairly well in other tasks. In particular, the approach this year used probabilistic text retrieval based on logistic regression and incorporating blind relevance feedback for all of the runs.

Experiments on a Multinomial Language Model versus Lucene’s Off-the-Shelf Ranking Scheme and Rocchios currently under development as part of the DIGMAP project. DIGMAP’s IR service is mostly based on Lucene, together with extensions for using query expansion and multinomial language modelling. In our runs, we experimented combinations of query expansion, Lucene’s off-the-shelf ranking scheme and t

WikiTranslate: Query Translation for Cross-Lingual Information Retrieval Using Only Wikipediatain translations. Queries are mapped to Wikipedia concepts and the corresponding translations of these concepts in the target language are used to create the final query. WikiTranslate is evaluated by searching with topics formulated in Dutch, French and Spanish in an English data collection. The s

Cross Language Experiments at Persian@CLEF 2008were involved in cross language text retrieval part of the track using two different CLIR approaches that are query translation and document translation. For query translation we use a method named Combinatorial Translation Probability (CTP) calculation for estimation of translation probabilities. I
