This paper describes one of the ways how to overcome some of the major limitations of current fulltext search engines. It deals with synonymy of the web search engine results by clustering them into rele- vant synonym category of given word. It employs WordNet lexical database and several linguistic approaches to classify results in search engine re- sult page (SERP) in appropriate synonym category according to Word- Net synsets. Some methods to refine the classification are proposed and some initial experiments and results are described and discussed.
