The development trend of sorting techniques The technology improvement and optimization of various search engines is directly reacted to the search results. Many search engines are further studying new sorting methods to enhance customer satisfaction. Professionals believe that there are still two shortcomings in the current search engine sorting algorithm. First, there is no truly solve correlation. Relevance refers to the degree of search term and page. Only by links such as links, fonts, locations, it is not possible to truly determine the relevance of search terms and articles, not to mention many of these features will not exist at the same time. This is also why many of the way to find the search engine. In addition, there are no search terms in some articles, but it is very relevant to search terms, such as searching for "terrorists", but some web is introducing some of the ruins of this Laden, and there are no "terrorists". Eyes, the search engine cannot be searched for this page. Surface features can only be treated and cannot be cured. The method of the cure should be to increase the language understanding, such as the number of subjects and keywords, analyze, to find the relevant degree of search words and web pages, the analysis, the better the effect. Second, the singularization of the search results. On the search engine, the results of anyone searching the same word are the same. This is obviously unable to meet the visitor. Scientists search "Planet", may want to know the knowledge of the planet, but ordinary people may want to find a "Star Wars" movie, but the search engine is the same result. How to meet these different types of visits, need to personalize the search results. Foreign Vivisimo (http://www.vivisimo.com/) is to solve this problem, and they use automatic clustering of search results to meet the needs of different types of customers. Search Results If you want to achieve it from single to personalization, Vivisimo has taken a step, but the ideal result should be related to each of the visits, sorting results and their search habits and will. Search "sports", people who like football should put the relevant results of football in front, people who like basketball should take the result of basketball in front. Searching techniques of search engines should also develop in the direction of solving these two shortcomings: language correlation and sorting personalization. The former needs a perfect natural language processing technology, the latter needs to record huge visitor information and complex calculations, to achieve any of the requirements, how to solve these problems, the task falls on the shoulders of scientists and engineers Which search engine solves these problems, she may be called the next dominion in the world.
