Embodiment Construction

[0085] attached figure 2 The flow of the method is described. The invention has wide adaptability and applicability for improving the search engine performance. The following uses the logs of four commonly used search engines to reorder the search results of the fusion of user behavior information of multiple search engines, and describes the detailed process of the above method:

[0086] 1. Data preprocessing

[0087] The logs used include user query and click information records of four common search engines collected within 37 days from March 18, 2007 to April 23, 2007, with a total of 58,092,696 non-empty query and click information Articles (the four search engines respectively have 32,983,339 articles, 11,159,594 articles, 3,450,045 articles, 10,499,718 articles). Information included in the record is:

Abstract

The invention belongs to the field of Internet information processing, and is characterized in that: it firstly utilizes the user number information corresponding to the query according to single or multiple search engine logs to filter out the common query set concerned by users; The user click rate corresponding to the page clicked by the user. If the log information of multiple search engines is used, the user click rate is merged; the user click rate is effectively filtered according to the user click rate, and the relevant query and the corresponding result page address are saved to the relevant database; finally, when the user submits the query request, the results obtained from the user information and the results obtained by the search engine are effectively integrated, and the results are reordered and returned to the user. The method has the advantages of automatic computer completion and real-time, effective and objective submission of search engine performance.

Description

technical field [0001] The invention belongs to the field of Internet information processing, and in particular relates to an information retrieval system, specifically a processing method for reordering search engine retrieval results by utilizing group user behavior information and improving retrieval and ranking performance. Background technique [0002] A search engine is a computer system that collects information on the Internet according to a certain strategy, organizes and processes the information, and provides users with network information services. It includes three parts: computer network, computer hardware system, and software programs running on the hardware system. . Its main function is to help users quickly and efficiently obtain high-quality information that exists in the Internet information environment and can meet user needs. [0003] At present, the general network search engine mainly includes three parts: information collection, information processi...
