The paper adopts the semantic matching technology combining with information retrieval method of semantic morpheme and expanded matching. It puts forward the theme information retrieval method which is basedon two kinds of similarity calculations to improve  system application. The research shows that the information retrieval system is able to combine many advantages, provids a more flexible and intelligent search method to reflect the effect of a better knowledge services.
