Abstract
In the domain of biomedical publications, synonyms and homonyms are omnipresent and pose a great challenge for document retrieval systems. For this year's TREC Genomics Ad hoc Retrieval Task, we mainly addressed the problem of dealing with synonyms. We examined the impact of domain-specific knowledge on the e#ectiveness of query expansion and analyzed the quality of Google as a source of query expansion terms based on pseudo-relevance feedback.
