Automatic query expansion using SMART: TREC- 3. In Proc. of the Third Text REtrieval Conference (TREC-3). NIST Special Publication 500-225, 1995.

Abstract. Most casual users of IR systems type short queries. Recent research has shown that adding new words to these queries via odhoc feedback improves ...

This paper further introduces an improved version called AbraQ2, which changes the way in which aspect vocabularies are constructed, and introduces a new ...

... Query Expansion (QE) methods aim to improve results for poorly formulated queries, by automatically adding related terms to a query (M. Mitra, Singhal, and ...

Experimental results show that refining the set of documents used in query expansion often prevents the query drift caused by blind expansion and yields ...

This paper further introduces an improved version called AbraQ2, which changes the way in which aspect vocabularies are constructed, and introduces a new ...

The automated process is more efficient since it improves both recall and precision. In Section 2 of this article we will survey the query expansion issue.

In this paper we have suggested information theoretic measures to improve efficiency of co-occurrence based automatic query expansion. We have used pseudo ...

... improve e ectiveness; our TREC 2 results suggested just changing expansion amounts on a per-query basis would yield only a small improvement. We examine ...

Experiments have shown that this kind of query expansion results in notable improvements of the retrieval effectiveness if measured the recall/precision in ...
