Development of a self-adaptive Web search engine

As the Web evolves towards the direction of providing more and more information, locating the desired information efficiently becomes a very important issue. Web search engines are very useful information search tools in the Internet. Current Web search engines produce search results relating to the search terms and the actual information collected by them. Since the selections of the search results cannot affect the future ones, they may not cover most people's interests. Feedback information produced by users' accessing lists can influence the search results. Thus the search engines can provide self-adaptability.
