Problems solved by technology

[0005] Existing meta-search engines call member search engines according to equal weights, and directly merge and sort the returned search results according to the principle of priority, or sort according to position, or use relevant scores to perform fusion sorting, which does not take into account The user's actual needs, hobbies, browsing and viewing of sorted results, etc.

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] like figure 1 As shown, a sorting algorithm of meta search results based on the refusal strategy, the user registration and login module, in order to better serve users and provide users with more accurate information retrieval services, register the user's basic information when registering, including Geography, industry, education level, hobbies, etc., to get a preliminary understanding of user preferences.

[0053] When a user logs in, the stored user information is used to verify the legitimacy of the user requesting to log in, so that the registered user can log in to the website for retrieval activities, and provide the user with a corresponding retrieval strategy based on user preference information to improve retrieval accuracy. The default setting for users who log in for the first time is to select all member search engines, and each member search eng...

Abstract

The invention discloses a meta search result ranking algorithm based on the rejection strategy. The algorithm includes after a user logged in after registration, allowing a system to retrieve the correlative preference information of the user; focusing on an input retrieve request of the user and distributing according to the member search engines selected by the user; calculating the correlation of the retrieve results and ranking according to the improved Borda method and presenting to the user; adjusting the member search engine weights according to the clicking situations of returned results of the user till rejecting retrieving one member search engine, and optimizing the user preference model. The meta search result ranking algorithm based on the rejection strategy is adaptive to meta search engines of the internet and has the advantages of high accuracy and wide coverage.

Description

technical field [0001] The invention relates to a sorting algorithm of meta search results based on a rejectable strategy, and belongs to the technical field of search engine methods. Background technique [0002] With the rapid development of the Internet, network resources have increased dramatically, and how users can effectively obtain the information they need has become a topic worth studying. Search Engine (Search Engine) refers to a system that collects information from the Internet by using specific computer programs according to a certain strategy, provides users with retrieval services after organizing and processing the information, and displays relevant information retrieved by users to users. . The emergence of search engines has greatly improved people's ability and efficiency of Internet information retrieval. According to the data of the "33rd Statistical Report on China's Internet Development Status" released by China Internet Network Information Center (...
