The Research And Design Of Web Data Mining System Based On E-Commerce

Data mining means extracting useful knowledge and information automatically from the mass of data. Data mining has become an important field in the study of database and rnachine leaming.Currently World Wide Web is developing rapidly in broadness and depth.By applying the approaches of Data mining into web to solve some problems, a new field "Web mining" is presented.The object is of Web Mining include all kinds of Web data: content of web pages, structure between pages, usage information of users. With Data mining we can find useful knowledge, extract knowledge from WWW, improve web site designing, and develop e-commerce more effectively.Electronic Commerce is defined as "any activity that utilizes some of electronic communication in the inventory, exchange advertisement, distribution or payment of goods and services". Compared with traditional commercial activities it has advantages such as cost saving and it is unrestricted by the zone.This paper is mainly focused on application of Data Mining in Electronit Commerce and main tasks are as follows:1. Summarizing status of Data Mining and its latest evolvement. Putting forward a Data Mining model and some current problems.2 Analyzing Web mining technology and application of Web Mining.3. Studying how to utilize path analyze, association rule analyze, sequence pattern analyze, classification analyze and cluster analyze to mine the customers' purchasing and browsing pattern effectively. Bring fonvard implementation methods4. We introduce the general steps for Web usage mining, bring some key technique of data mining, such as data preprocessing, clustering algorithm, association rules, etc, into web usage mining. We give evaluation and verification to above technique by a series of experiments. Finally we built the prototype of a web usage mining systemWeb Mining is trying to find valuable commercial information from large Database. The wonderful combination of Data Warehouse, Data Mining and Internet will lead to splendid foreground in 21st century.
