The Web Interface for Statistics Education (http://wise.cgu.edu) is a website built around interactive tutorials designed to teach introductory and advanced statistical concepts. The tutorials use Java applets that dynamically illustrate the statistical concepts being taught. By using Java applets, we teach statistics in a manner not possible in a traditional classroom environment. In this pape...

W use data from a large-scale field experiment to explore what influences the effectiveness of online advertising. We find that matching an ad to website content and increasing an ad’s obtrusiveness independently increase purchase intent. However, in combination, these two strategies are ineffective. Ads that match both website content and are obtrusive do worse at increasing purchase intent th...

Due to the lack of efficient refresh techniques, current crawlers add unnecessary traffic to the already overloaded Internet. Frequency of visits to sites can be optimized by calculating refresh time dynamically. It helps in improving the effectiveness of the crawling system by efficiently managing the revisiting frequency of a website; and appropriate chance to each type of website to be crawl...

In this paper, we explore sets visualization, a rather new topic in information visualization. We propose four approaches for representing sets and their relations – scatter, similarity lattice, and cluster view and permutation matrix. They cover most demands of sets visualization, including one-to-multi, multi-tomulti similarity, grouping and relevance sorting. Three experiments on website dir...
