Web Log Based Data Mining

One of the most important fields in database is Data mining. In view of its wide application and practical significance, the technique and application of data mining developed rapidly and attracted much more attention both in fields of academic research and information industry.Discovering the interested, hidden and unknown data from large data sets is the purpose of data mining. The main work of data mining is to deal with the structural data, whi le the web data mining is based on Internet to get the interesting and potential pattern from the half structural or not structural web pages. Data in Internet is a half structural system, and it is difficult to deal with them. Fortunately, the web sever log files have a nice structure and it is very convenient for data mining. Furthermore, web log mining is a branch of web usage mining and has special theory and practice significance as an important part of web mining.In this thesis, the process of data mining, web data mining and web log mining was reported. Focusing on the web log mining, the method and technology of web log mining were discussed in this thesis. Finally, the technology of web log mining wasapplied to shangqiu information web station (http://www. sqinfo. ha. en). Through the mining of its web sever log files, a data mining system based on web log mining was estabiish. The estabiished data mining system will faci Iitate the station management, the improvement of the design of web station and the security of network. At the end, the future direction and works in web log mining were proposed.
