The Method Research Of The Network Dynamic Specialized Search Engine Construction

With the fast development of Internet, the resources of it grow very rapidly. As result, not only strengthen the use of Internet, but also more and more people take the information from the web. Although we have many search engine such as Yahoo, people also feel searching information difficult. Especially search one specialty or for one area. For the founding of the specifically information needed more acutely and more effectively, the construction of tools for one type or for one area professional search engine has become the urgent need for the web.As a result of discipline enhancing comprehensive quality, On one hand has caused the specialized resources increased sharply, and have various resources in the web. In order to collecting these dynamic and static information, it is a inevitable direction for the specialized search engine development. On the other hand has many new professional words. However, all kinds of specialized network resources have not kept pace with the discipline development. Therefore, it is difficult to search new professional words with the existing specialized search engine. Obviously, the ordinary specialized search engine already did not suit people to search the specialized information. For the purpose of solving the problem, it is essential to establish a kind of network dynamic specialized search engine.At present in overseas, more and more people have studied the subject search engine research, and have had some successful specialized search engines project. But in our country it is at the start stage and had less research about specialized search engine. Base on the question which the current specialized search engine face to, this article proposed a method constructing network dynamic specialized search engine. The network dynamic specialized search engine has carried the optimized on its Robot by researching ordinary specialized search engine. It increased a gaining knowledge module in its specialized storehouse. The search engine arranged its result with the vector space model combining with PageRank algorithm. It also has "The classified——subjectuser" surface and based on gathers of visible result performance technology.
