Embodiment Construction

[0082] Accompanying drawing 2 has described the process flow of this method. 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:

[0083] 1. Data preprocessing

[0084] The logs used include user query and click information records of four commonly used 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 (four The search engines have 32,983,339, 11,159,594, 3,450,045, 10,499,718, respectively). Information included in the record is:

Abstract

The invention belongs to internet massage processing field, characterized in that: common inquiry set which is cared by user, according to one ore more search engine logs, is screened out firstly using the inquiry of corresponding information of user number; then calculating user touching ratio corresponding to user touching page of inquiry in common inquiry set, if multi-search engine logs is used, user touching ratio are united; user touching pages are effectively screened out based on user touching ratio, the ralated inquiry and corresponding result page address are stored related database; at last, the result from user information and the result by searching by search engine are united effectively when user puts in the demand of inquiry, and are reordered to return to user. The method has the advantage that computer is completed automatically and efficiently submits search engine performance in real time and objectively.

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...
