| Abstract(in English) | When a user input multiple keywords to a search engine, he usually assume these keywords to have some different roles in describing the topic of interest. For example, the user may use some keyword as the subject and use other keywords for specifying the scope of the topic. By treating keywords defferently according to their roles in the query, there is a possibility of improving the search results. We conduct preliminary experiments by submitting two different types of queries to an existing search engine: queries that require the one keyword in the title and the other one in the body, and queries of just the conjunction of these two keywords. The results are encouraging because the results of these two types of queries have difference in their contents. Therefore, we generalize the setting of the experimnets and propose the new method of web search using the hierarchical structure of topics. We also present the applications of our method to query modification and search results organization. |
