T2 : E-Commerce and Clickstream Mining
Ronny Kohavi, Blue Martini Software, Inc.
Jon Becher, Accrue Software, Inc.
Sites conducting electronic commerce or providing content can generate
significant amounts of data that can help gain insight about the visitors,
allowing for improved interactions through personalization. The tutorial
reviews the value proposition for mining e-commerce and clickstream data,
presents several case studies, and takes the attendees through possible
architectures for data collection, warehousing, analysis, and closing
of the loop back to the web site. We review data collection through web
logs, sniffing, application server logging. We look at the advantages
and disadvantages of building a data warehouse, and present implicit and
explicit ways to "close the loop." Finally, we review the building blocks
of successful solutions for analysis, including data transformations,
reports, visualizations, OLAP, and mining algorithms.
