The emerging interdisciplinary study of Web-based support systems focuses on the theories, technologies and tools for the design and implementation of Web-based systems that support various human activities. This book presents the state-of-the-art in Web-based support systems (WSS). The research on WSS is multidisciplinary and focuses on supporting various human activities in different domains/fields based on computer science, information technology, and Web technology. The main goal is to take the opportunities of the Web, to meet the challenges of the Web, to extend the human physical limitations of information processing, and to keep up with the advance of technology advances. This book discusses the four types of existing research: WSS for specific domains, Web-based applications, techniques related to WSS and design, and development of WSS. This comprehensive, wide-ranging text will provide an invaluable insight into the state of the art in WSS for researchers and graduate students.
