User profile is an essential component for accessing the personalized information from the Web. Efficiency of personalized accessed information highly depends on how to model the user details to construct user profile. Previously, user profile was constructed by collecting list of keywords to inferring user interests. These kinds of approaches are not sufficient for many applications.

User's query is extended using on-tological profile for generation of personalized search context. Experimental results show that our method of constructing semantic profile is effective for searching information with individual needs.
