Design And Implementation Of Topic Search Engine Based On The Circuit Curriculum

At present Internet search engine service provider like Yahoo, baidu, Google and so on, can provide the crosswise magnanimous information searches for the user. But now , The general network user wanted to find the material which is special , However synthesizes the search engine to be possible to satisfy the massive information the crosswise search, but it's very difficult to give dual attention to the search in the accuracy and the degree of correlation quality.The comprehensive search engine's value lies in the massive information guidance, regarding the information need relative centralism, classifies the more detailed profession customer to lack the guidance. In order to solve this problem, which become the opportunity of the search development, also it will become the scientific research hot spot in the future. The subject searches that the new search pattern is produces under this background. The main research work of the article divides into two parts: The first part through the fundamental research analysis, proposed to the subject search engine information acquisition algorithm improvement mentality; The second part through carries on the analysis to the subject search engine's core technologies, designed and realized a subject search engine's prototype system. The textual introduced search engine's historical development in detail, and pointed out present synthesizes the question which the search engine faces as well as solves these question way, namely this article studies direction: Topic search engine. Through comparative analysis between the synthesis search engine and the topic search engine in the information service and key technologies, points out the topic search engine existence the huge superiority and the development opportunities. And describes the design search engine technology to be prepared, then establish the topics search framework , mainly includes three parts: web crawling module, the index module, query module, this chapter focuses on web crawling algorithm analysis , on the context of web pages crawling ,we limit the scope to improve the extraction of effective. At last we describle the implementation of topics search engine,Using Lucene framework to design and build a theme for the circuit theory of information search engine prototype.
