چکیده

Web usage mining is the application of data mining techniques to discover usage patterns and behaviors from web data (clickstream, purchase information, customer information etc) in order to understand and serve e-commerce customers better and improve the online business. In this paper we present a general Data Warehouse/OLAP framework for web usage mining and business intelligence reporting. We integrate the web data warehouse construction, data mining, On-Line Analytical Processing (OLAP) into the e-commerce system, this tight integration dramatically reduces the time and effort for web usage mining, business intelligence reporting and mining deployment. Our Data Warehouse/OLAP framework consists of four phases: data capture, webhouse construction (clickstream marts), pattern discovery and cube construction, pattern evaluation and deployment. We discuss data transformation operations for web usage mining and business reporting in clickstream, session and customer level, describe the problems and challenging issues in each phase in details and provide plausible solution to the issues and demonstrate with some examples from some real websites. Our Data Warehouse/OLAP framework has been integrated into some commercial e-commerce systems. We believe this Data Warehouse/OLAP framework would be very useful for developing any real-world web usage mining and business intelligence reporting systems.
