Abstract(in English) In this paper, we propose a method to improve precision of WWW search engines. When Web search engines are used, the user inputs keywords. Web search engines accept a few keywords as a retrieval condition, and select candidate pages based on some statistics value such as TF/IDF and so on. We think that the keywords input by users have a semantic relation. We try to improve retrieval accuracy by checking whether two keywords have a dependency relation in the candidate pages or not. We deal with sentence as a structure to represent dependency relations between keywords. We construct a meta search engine which accept output of an ordinary search engine and select plausible ones by checking dependency relation. We also show an experimental evaluation of our method.
