Abstract


Information on the Internet in the explosive growth in the face of such a vast resource of search engine users surf the web provides an entrance, it is no exaggeration to say that , all users from the search engine Departure Arrival go online place. Therefore , it has also become the most used in addition to e-mail other than online services . However, with the growth of information on a wide range of size-fits to all users with an entry apparently been unable to meet specific user deeper query needs . At the same time , such a general search engine shortcomings to obtain more comprehensive information on the Internet , it is difficult to update . In view of this situation , we need a detailed and accurate classification of low hardware requirements , comprehensive and in-depth data updated timely subject-oriented search engine . Topic search engine research, analyzes the index terms extraction and segmentation , hyperlink analysis as well as topics related to the degree of specific algorithms and implementation of the search strategy . Browser / Server structure , to achieve a comprehensive , efficient and flexible information retrieval . HTML syntax based on the extraction algorithm given HTML page content and links . URL with the theme of judgment , on FishSearch algorithm has been improved . In the judgment of the page with the query , use more mature in natural language processing , keyword - based vector space model calculated the similarity of the page with the query .
