Abstract
Queries have specific properties, and may need individualized methods and parameters to optimize retrieval. Length is one property. We look at how two-word queries may attain higher precision by re-ranking using word co-occurrence evidence in retrieved documents. Co-occurrence within document context is not sufficient, but window context including sentence context evidence can provide precision improvements at low recall region of 4 to 10% using initial retrieval results, and positively affects pseudo-relevance feedback.

CIKM '05: Proceedings of the 14th ACM international conference on Information and knowledge managementThis paper presents a new approach to determine the senses of words in queries by using WordNet. In our approach, noun phrases in a query are determined first. For each word in the query, information associated with it, including its synonyms, hyponyms, ...
