Abstract

The WWW and its associated distributed information services provide rich world-wide online information services, where objects are linked together to facilitate interactive access. Users seeking information of Internet traverse from one object via links to another. It is important to analyze user access patterns which will help improve Web page design by providing an efficient access between highly correlated objects, and also assist in better marketing decisions by placing advertisements in frequently visited document. We need to study the user surfing behavior by examining the Web access log, browsing frequency of Web pages and computing the average duration time of visit. This paper offers an architecture to store the derived web user access paths in a data warehouse, and facilitates its view maintainability by use of a metadata. The system will update the user access paths pattern with the data warehouse by the data operation functions in the metadata. Whenever a new user access path occurs, the view maintainability is triggered by a constraint class in the metadata. The data warehouse can be analyzed on the frequent pattern tree of user access paths on the Website within a period and duration. The result is an online analytical mining path traversal pattern. Our experimental and performance studies have demonstrated the effectiveness and efficiency of our system with the following contributions: an architecture of online analytical mining (OLAM) using frame model metadata, a methodology (stepwise procedure) of implementing OLAM and the resultant cluster of web pages frequently visited by users for marketing use.
