The latest technology development of the search engine includes the following aspects: 1. Improve the search engine's understanding of the user search question In order to improve the understanding of the search engine to search for users, there must be a good search question language, in order to overcome keyword retrieval and The shortcomings of the directory query have now appeared natural language intelligent repayment. Users can enter a simple question, such as "How Can Kill Virus of Computer?". Search engines After the analysis of the question, or directly give the answer, or boot the user from several alternative problems. The advantage of natural language is that one is to make network communication more user-friendly, and the other is to make the query more convenient, direct and effective. In terms of the above example, if you use keyword queries, many people will retrieve the word "virus". The results will inevitably include all kinds of viruses, how to generate many invalid information, and use "How can Kill Virus of Computer?", The search engine will provide information to the user to provide the user, improve the retrieval efficiency. Second, the search results for the search results 1) Search engine based on link evaluation Based on link evaluation of the outstanding representative of the search engine for the search engine is Googel (http://www.googel.com), its original "link evaluation system" is based on this Awareness, the importance of a web page depends on the number of pages that have been linked by other web links, especially some of the number of pages that have been identified as "important". This evaluation system is very similar to the idea of "scientific citation index", but because the Internet is developed in a commercial environment, a website has a close relationship with its business promotion, so this The evaluation system lacks objectivity to some extent. 2) Based on access to popular search engines based on the representative of the popular search engine is Direct Hit, its basic concept is the most important website to choose access to websites. According to the previously tens of online users actually selected and visited by the website and the time spent on these websites, they determine the importance of the website, and to determine which websites are most in line with users. Retrieval requirements. Therefore, it has a typical manner. This evaluation system has the same shortcomings with search engines based on link evaluation. 3) Remove the extra information added in the search result According to the survey, too much additional information increases the user's information burden, in order to remove these excessive additional information, user customization, content filtration, etc. can be used. Third, determine the search engine information collection range, improve the pending search engine 1) Vertical Theme Search Engine online information is like smoke sea, network resources grow in ten times fast, a search engine is difficult to collect all the topics network information, even if the information theme It is more comprehensive, because the theme is too wide, it is difficult to make the subjects to do accurate and professional, so that there is too much garbage. In this way, the vertical search engines have occupied a series of seats in all kinds of search engines in various search engines, such as the search engine such as stock, weather, news, etc., such as the search engine such as stock, weather, news, etc.. The user has a higher satisfaction with the results of the query. The author believes that the vertical theme has great development space. 2) Search for non-WWW information Provide search for FTP and other types of information. 3) Multimedia search engine multimedia retrieval mainly includes sound, image search. 4. Putting the technology development of the search engine in the processing of search results, providing more optimized search results 1) Pure search engine This search engine does not have its own information acquisition system, using someone else's existing index database, main attention The idea, technology and mechanism of retrieves, etc.
