Abstract: In the integration process of search results returned from multi member search engines, the quality of a service meta-search engine is determined by the ranking of search results to a great extent. The current technologies on achieving effective integration of search results mainly rely on combining search queries, document content, the initial sorting information or（and） endowing the member search engines with weights, and others. The method of endowing engines with weights is objective, often depends on the subjective experience of users, and can’t embody users’ search preferences. So, this paper proposes a method to dynamically endow the member search engines with weights based on mining user’s searching and navigation habits. It analyzes users’ log data on clicking and downloading search results, and gets the matching degrees between search results and users’ navigation. The statistic results demonstrate that the methodology is feasible and effective to the ranking of multi engine search results.
