Expanding Queries Using Stems and Symbols

Download trec.nist.gov

This paper describes the experiments conducted in the ad-hoc retrieval task of the Genomic track at TREC 2004. Different query expansion techniques based on the addition of keyword stems and of genomic product symbols selected by relevance feedback were studied. Stemming was tested using a mutual reinforcement process for building a domain-specific stemmer. Relevance feedback was tested using a technique exploiting associations between symbols and related keywords.
