Symbol-Based Query Expansion Experiments at TREC 2005 Genomics Track.
Michela Bacchin, Massimo Melucci · 2005
This paper illustrates the activity conducted at the TREC 2005 evaluation campaign in the ad-hoc task of the Genomics track. The retrieval e#ectiveness of a relevance feedback query expansion algorithm, which is based on symbols, is studied. The experimental results suggest that query expansion based on implicit relevance feedback is not always an effective means for improving e#ectiveness in this domain-specific context.
