The use of lexical semantic knowledge in information retrieval has been a field of ac- tive study for a long time. Collaborative knowledge bases like Wikipedia and Wik- tionary, which have been applied in com- putational methods only recently, offer new possibilities to enhance information retrieval. In order to find the most bene- ficial way to employ these resources, we analyze the lexical semantic relations that hold among query and document terms and compare how these relations are repre- sented by a measure for semantic related- ness. We explore the potential of different indicators of document relevance that are based on semantic relatedness and com- pare the characteristics and performance of the knowledge bases Wikipedia, Wik- tionary and WordNet.
