Abstract: In a process of determining search results based on a search keyword, objects related to the search keyword are determined from extension objects having an association relationship with an object for which a user conducts a historical behavior, and are used as a part of the search results. Therefore, the search results are close to the user's behavioral habits and accurate for the user.

Abstract: After multiple objects related to a keyword are found, presentation values of the objects are calculated by combining multiple similarity measures between the objects and a historical behavior object of a user, and the objects are presented according to the presentation values of the objects. The similarity measures use the historical behavior object of the user as a reference, and the presentation values consider similarity degrees between to-be-presented objects and the historical behavior object of the user from multiple perspectives; therefore, a search result is coincident with the behavior habit of the user.
