Embodiment 1

[0039] Below we use an example to illustrate the Web information retrieval method based on multiple search engines. Assume that the text string entered by the user is "Xu Wenya, Tianjin University of Technology". Two search engines are considered: WSE1 and WSE2. The above concepts will be described based on this search example.

[0040] 1st, the user enters the search text string S = "Xu Wenya of Tianjin University of Technology" and submits it;

[0041] 2nd, the search text string is passed into the general controller (such as figure 1 ), the general controller is responsible for the scheduling of each search engine;

[0042] Step 2.1, the general controller preprocesses the incoming search text string S.

[0043] 2.2, the general controller is responsible for scheduling the crawler program, generating two crawler threads P1 and P2;

[0044] 2.3, the crawler thread P1 simulates the client to submit the user-input text string "Tianjin University of Technology Xu Wenya" to t...

Abstract

Provided is a Web information retrieval method based on multiple search engines. The method comprises the steps that a text sting input by a user is automatically submitted to the multiple different search engines through a webpage crawling program by using a producer and consumer model, and then searching results are extracted from web pages returned by all the search engines, and then are combined and de-weighted. On the basis, each result web page is graded through a forward direction maximum participle matching method, and the results are ranked according to scores. According to the Web information retrieval method based on the multiple search engines, the meta-search technology is combined with the forward direction maximum participle matching method, and a solution is proposed for solving the problem that a single search engine cannot meet searching requests of a user under certain situations. The method is novel in concept, has the advantages of being concise, practical and easy to implement, is capable of greatly saving the trouble of switching the search engines by the user, and improves the quality of the search results.

Description

technical field [0001] The invention belongs to the field of Web information retrieval, in particular to a method for Web information retrieval based on multiple search engines. Background technique [0002] At present, the Internet has become an important resource for people to obtain information, and major search engines are the main tools for people to obtain information. However, in the face of such rich web resources, it is not easy to use the current search engine to find the information you really need. The reasons mainly include: (1) the number of web pages indexed by each search engine is only a small part of the entire web information world; (2) the content of web pages indexed by each search engine has certain differences. Using the same keyword to search in different search engines, you will find that the search results sometimes vary greatly. This shows that different search engines have their own characteristics and advantages, and it is difficult to perfectl...
