Abstract

In the domain of genomic research, the understanding of specific gene name is a portal to most Information Retrieval (IR) and Information Extraction (IE) systems. In this paper we present an automatic method to extract genomic glossary triggered by the initial gene name in query. LocusLink gene names and MEDLINE abstracts are employed in our system, playing the roles of query triggers and genomic corpus respectively. The evaluation of the extracted glossary is through query expansion in TREC2003 Genomics Track ad hoc retrieval task, and the experiment results yield evidence that 90.15% recall can be achieved.
