Abstract

The invention provides a search engine and a realization method thereof. The method comprises: receiving an original query of an active user; identifying an original word contained in the original query, a potential synonym pair containing the original word and a synonym of the original word, and the synonym context of the potential synonym word pair; determining if the synonym context matches the original query, and if the synonym context matches the original query, substituting the synonym for the original word in the original query to obtain a synonym query mode; and based on the original query and the synonym query mode search, acquiring a set of the result web pages. Through determining a semantic environment, the search engine provides an accurate synonym expansion query, thereby providing a complete and accurate search result for the user and guaranteeing a good usage experience to the user at the same time.
