The paper "Web Usage Mining: Discovery and Applications of Usage Patterns from Web Data" by Jaideep Srivastava, Robert Cooley, Mukund Deshpande, and Pang-Ning Tan provides an in-depth overview of web usage mining, a field that applies data mining techniques to uncover usage patterns from web data. The authors outline the three main phases of web usage mining: preprocessing, pattern discovery, and pattern analysis. They discuss the challenges and techniques involved in each phase, including the collection of web data from various sources such as server logs, client-side agents, and proxy servers. The paper also covers the taxonomy of web usage mining projects and their applications, such as personalization, system improvement, site modification, business intelligence, and usage characterization. Additionally, it introduces the WebSIFT system, a prototype for web usage mining, and addresses privacy concerns in the context of web usage data collection and analysis. The authors conclude by highlighting the growing interest in web usage mining and the need for further research to address scientific challenges.The paper "Web Usage Mining: Discovery and Applications of Usage Patterns from Web Data" by Jaideep Srivastava, Robert Cooley, Mukund Deshpande, and Pang-Ning Tan provides an in-depth overview of web usage mining, a field that applies data mining techniques to uncover usage patterns from web data.
