As Internet use becomes increasingly widespread, users continually raise demands on its applications and services. However, Internet services - usually created by software developers - do not currently possess intelligent and self-adapting functions. Fortunately, the development of component technology, artificial intelligence technology, data mining and Web service technologies laid a solid foundation for research and development into active self-adapting services. "Active Service: Concepts, Architecture and Implementation" touches upon two new concepts in computer and Internet sciences. "Active Service: Concepts, Architecture and Implementation" address the constraints of Web services, which are generally based on fixed models and are incapable of adjusting to user requirements. "Program mining" involves searching for existing components on the Internet and reusing them according to requirements. Формат: 16 см x 23,5 cм.
