Research And Implementation Of Intellectualized Web Information Search Engine

Information on the Internet is very huge and distributed, search engine has more and more become an absolutely necessary tool of Internet surfers. Search engine is an information retrieval Web site, which can use Web robots or Web site entry to collect documents, then analyzes and deals with this information, creates and maintains index database, gives a service of search to the user. When user input a keyword to query, this Web site can give all the documents' abstracts and links including this keyword.Now, many search engine systems are already in use on the Internet, but these search engines have some bugs in function or quality, especially in the rate of precision and whole of information. Studying and developing the new search tools is an urgent problem, which can help user conveniently to retrieval information on the Internet.This paper mainly discusses the theory and technology of search engine, discusses the character of pages on the Internet, compares and analyzes the search engines used on the Internet, and implements two types of Web search engine systems based on these work: one is based on directory, the other is based on Web robots. These two types of Web search engines are linked each other and recruited each other, so come to an intellectualized Web information search engine system.Now, this search engine system has experimentally run and the result is excellent. This system has reached its goal of experiment and study. The method can study the theory and develop the search engine system more. So the method is the base on the further research.
