Query expansion consists in extending user queries with related terms in order to solve the lexical gap problem in Information Retrieval and Question Answering. The main difficulty lies in identifying relevant expansion terms in order to prevent query drift. We propose to use definition clusters built from a combination of English lexical resources for query expansion. We apply the technique of pseudo relevance feedback to obtain expansion terms from definition clusters. We show that this expansion method outperforms both local feedback, based on the document collection, and expansion with WordNet synonyms, for the task of document retrieval in Question Answering.
