Abstract


The rapid development of the Internet , especially the global popularity of the Web , making the amount of information on the Web incomparably rich . Web mining can extract desired knowledge from the Web page : the total user access behavior , frequency , content analysis , available to the general knowledge of the behavior and the way groups of users access to improve Web services design . More reuse is through the understanding and analysis of the characteristics of these users , help to carry out targeted e-commerce activities . Web log mining data mining technical analysis and mining web logs , a valuable model for site usage , applied to personalized service , website design and business decisions . Data preprocessing plays a vital role in the process of Web log mining , user identification and session identification is the main link , but also the basis of the whole process and key steps . The research will improve user identification and session identification algorithm . This paper systematically expounded from data mining , Web data mining to Web log mining the whole process , and focus on the Web log mining technology and its steps , the process and methods of data preprocessing , including user identification and session identification technology . The main work of this paper is an active user - based user identification algorithm , it uses the IP address and user access to the cut-off time to identify different users log Experimental results show that the algorithm has a basic user identification algorithm better performance , even for small log file systems are also suitable. Secondly, given the definition of the session identification , and optimized for the traditional method of pre- set time interval , specific description of the algorithm , the experiment proved session quality has been improved on the basis of the algorithm data structure is given .
