b>Summary: When referring to genes, authors often use synonyms instead of the official gene symbols. In order to accurately retrieve as many relevant documents as possible, we have developed GeneE, a web application that expands a gene query to include all known synonyms, and adds disambiguation information for ambiguous terms, before forwarding the query to either PubMed, Google, or Jane. The query expansion algorithm is also available as a web service. Availability: http://biosemantics.org/geneE Contact: m.schuemie@erasmusmc.nl</inter-ref
