A competitive environment for exploratory query expansion [PDF]
, 2008 Most information workers query digital libraries many times a day. Yet people have little opportunity to hone their skills in a controlled environment, or compare their performance with others in an objective way.

Evidence combination for multi-point query learning in content-based image retrieval [PDF]
, 2004 In multipoint query learning a number of query representatives are selected based on the positive feedback samples. The similarity score to a multipoint query is obtained from merging the individual scores.

WORD SENSE DISAMBIGUATION METHOD USING SEMANTIC SIMILARITY MEASURES AND OWA OPERATOR [PDF]
ICTACT Journal on Soft Computing, 2015 Query expansion (QE) is the process of reformulating a query to improve retrieval performance. Most of the times user's query contains ambiguous terms which adds relevant as well as irrelevant terms to the query after applying current query expansion ...

Improving automatic query expansion [PDF]
Proceedings of the 21st annual international ACM SIGIR conference on Research and development in information retrieval, 1998 Most casual users of IR systems type short queries. Recent research has shown that adding new words to these queries via odhoc feedback improves the retrieval effectiveness of such queries. We investigate ways to improve this query expansion process by refining the set of documents used in feedback. We start by using manually formulated Boolean filters

A Query Understanding Framework for Earth Data Discovery
Applied Sciences, 2020 One longstanding complication with Earth data discovery involves understanding a user’s search intent from the input query. Most of the geospatial data portals use keyword-based match to search data.

Cluster-based query expansion [PDF]
Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval, 2009 We demonstrate the merits of using document clusters that are created offline to improve the overall effectiveness and performance robustness of a state-of-the-art pseudo-feedback-based query expansion method -- the relevance model.
