Abstract

In this paper we experimentally study the impact of normalized query expansion on Web Information Retrieval. In this respect, we have implemented a query expansion module, which firstly normalizes the user submitted queries and subsequently attempts to enrich them with semantically related terms that are obtained from WordNet. Experimental results demonstrate that for certain query types our module has a potential in giving improved search results in terms of relevance, compared to the results retrieved for the same queries by other retrieval methods.
