Researching And Development On The Professional Biology Resource Search Engine Basing On Java Technology

With the fast development of Internet, the information of it growing very rapidly. Because of it, it is very difficult for people to search the information they need. Search engine improves the people's ability to collect and locate the useful information and help them to find the information the need rapidly. In the following several years the technology of search engine begins developing continually, the amount of search engine system grows very rapidly, the technology of search engine system basing on the information of Internet has become hotspot problem.With the application of search engine system broadly, the requirement of people to search engine system is higher and higher, veracity and integrality have become new criterion for scaling search engine system and filtrating unuseful information also has become new problem which people begin paying attention to. Nowadays search engine isn't only considering collecting information but also consider finding the information user need quickly. Further more general search engine has not satisfied search requirement people need for specifically knowledge. Therefore multi-type search engine system begins to appear, professional and special search engine systems emerge in endlessly, the development of search engine tends to be humanistic and intelligent.Firstly, the article looks back the developmental course of search engine and introducing basic framework and achieved technique of it. Secondly, bringing forward the achieved framework of professional search engine -- biology resource professional search engine according to the disquisitive content and desiration of the item. Considering technology used, the article introduced Java technology, including characteristic, predominance, achieved technique and so on. Thirdly, analyzing and explaining the detail technique of the hexapod resource search web and professional biology resource search engine, including how Spider gains the web pages, how Chinese segment word module work, how biology resource filtration module come true, how index worker work and how to design user-interface. Finally, the article summarize the finished work, put forward existent lack and prospect the development of future search engine.
