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. 作者: dendrites 時間: 2025-3-22 02:12

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作者: 蛤肉 時間: 2025-3-22 11:10

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.

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作者: Daily-Value 時間: 2025-3-23 12:05

Thus, we have generated 13 indices and we have carried out 39 different experiments, obtaining that some indices based on WSD tools even outperforms slightly the non disambiguated baseline case. After the interpretation of our experiments, we think that only queries with terms very polysemous and very high IDF value are improved by using WSD.作者: Exposure 時間: 2025-3-25 09:58
