Research on User Requirement Knowledge Acquisition by User Access Behavior Analysis

Obtaining user requirement is a premise of demand-driven product design. By the analysis of several requirements acquisition methods, as well as the change of customer´s buying behavior under network conditions, this paper puts forward the methods of user requirement knowledge acquisition by tracking user´s browsing behavior. By data purification, user identification and session identification of server log files, the info of user´s visits over a period of time in the specific product-related Web sites is found; the user requirement items are extracted from the visited pages; user requirement values along with the reliability are computed based on the visited numbers of the requirement items. Then, users are divided into user groups to acquire user groups´ requirements knowledge. This method can not only help understand users´ concerns of existing products´ index, but also, to some extent, reflect users´ potential demand of the products, which, in turn, can provide enterprises reference for new product development.
