Abstract
Query expansion is a method of modifying an initial query to enhance retrieval performance in information retrieval operations [11] . There are alternate ways to expand a user input query such as finding synonyms of words, re-weighting the query, fixing spelling mistakes, etc. [11] . In this project, we created a query rewriting algorithm, which uses synonyms for a given word for query expansion. These synonyms were chosen using WordNet, a lexical database for English [16] [15] . Similarity ranking functions and a part-of- speech tagger were written to extract the essential data from WordNet output. Various experiments were carried out after integrating WordNet in Yioop to evaluate the improvement in search results and its throughput.
