While the area of Intelligent Support Systems has experienced significant progress in the recent past, the advent of Internet and World Wide Web has sparked a renewed interest in this area. There is a growing interest in developing intelligent systems that would enable users to accomplish complex tasks in a Web-centric environment with relative ease in utilizing such technologies as intelligent agents, distributed computing, and computer supported collaborative work. The purpose of this book is to bring together researchers in related fields such as information systems, distributed artificial intelligence (AI), intelligent agents, machine learning, collaborative work, to explore various aspects of IIS design and implementation, as well as to share experiences and lessons learned in deploying intelligent support systems.
