Abstract
In this paper, we describe the design and implementation of our software for visualizing web site access data, and several analysis results for the data set of an E-commerce site that was provided for the date competition organized by the Joint Association Study Group of Management Science. Our software displays session histories by polygonal lines separated by their colors. We implemented our software by the Java language and MySQL database. Our software can find the characteristics of browsing behavior just before the purchase of products. Therefore, it enables us to see products that were compared with the purchased one. In the e-commerce data set, we find that four kinds of session histories are clearly distinguished: purchasing the target product only, purchasing another product only, purchasing both the target product and another product, and just viewing products.
