The development trend of intelligent search engine

       Web search engine can provide users with a service to find the necessary resources, and has become the second largest service on the Internet after e-mail. This paper introduces the application and advantages of data mining in search engine. Finally, the development direction of the search engine is given.

Search engine is the navigation when people roam in the information ocean. It originated in some software for user-friendly search function, experienced from a single version to the network version, from the general to specialized, from artificial to intelligent development, has become the Internet is one of the most popular services. The search engine collects and discovers the information in the mutual network with certain strategies, understands, extracts, organizes and processes it, and provides the user with the retrieval service, thus it serves the purpose of information navigation.

The intelligent search engine takes the whole internet as a whole, ultra-large, dynamic database processing. The intelligent search engine mainly realizes 5 functions: Search request submission, scheduling policy generation, search engine scheduling management, search interface agent conversion and search result processing feedback function. Among them, the search request submission and the search result processing feedback function compose the user interface part, the other function is composed by the dispatch strategy generator, the search engine manager, the search engine agent 4 big module respectively.

(1) user interface part : The user interface part is the user interface of the system, which is responsible for receiving the user's request and converting the user's operation to the system standard request.

(2) search engine manager : The search engine manager requests the search engine Agent selection policy from the data Mining manager according to the system standard searching request which contains the user's request subject and geographical situation.

(3) search engine Agent Manager : Search Engine Agent Manager is a synthesis of several search engine agents. It transforms the received connection request into a localized connection request for the corresponding search engine invocation, activating the related engine to work.

(4) Data Mining Manager : Data Mining Manager is the main module that embodies the intelligent system. It is responsible for implementing the preprocessing function of search engine knowledge base and establishing search engine invocation strategy. The search records sent by the search engine manager are statistically collated, and the next search engine invocation strategy is modified according to the specific algorithm of data mining.
