Search Of WEB Mining And Realization Of Intelligent WEB Minning System Based On MLDB

The thesis recommends the concepts, relevant technology of WEB mining and information retrieval, and trends both at home and abroad at first, describes commonly methods and tools nowadays, realizes the synthesis intelligent engine system of IWMES on the basis of web data mining and multilevel database. This system is set up on the existing search engine foundations through Web Services' technology, has solved variety and non-structural WEB data with XML technology, has formed WEB multi- level data base, and constructed the system structure in high performance of data warehouse, utilized MIDAS technology to form the high-performance index storehouse structure, has remedied the deficiency of search engines at coverage, accuracy etc, and improved efficiency of information retrieval.The thesis explains the systematic structures, the basic functions of index storehouse, WEB multi-level databases and other constitutes. Not in detail introduces its realization principles and systematic frameworks, and, combining the module function flow charts of realization, states the whole systematic realization course. Finally, this paper realizes the intelligent system combination structure excavate and mining of content, and provides corresponding software flow charts, function structure charts of the module, implementation methods and some procedure codes, and some interconnected system algorithms used in the process of the realization of the system.
