A survey of service composition in ambient intelligence environments

摘要: This article presents a comparative review of systems performing service composition in Ambient Intelligence Environments. Such environments should comply to ubiquitous or pervasive computing guidelines by sensing the user needs wishes and offering intuitive human-computer interaction comfortable non-intrusive experience. To achieve this goal orientation is widely used tightly linked with AmI systems. Some these employ Web Service technology, which involves well-defined web technologies standards that facilitate interoperable machine interaction. Other regard services different (e.g. UPnP, OSGi etc) generally as abstractions various actions. operations are sometimes implemented software based functions actions over hardware equipment UPnP players). However, single satisfies an atomic only need, so need be composed (i.e. combined), order provide usually requested complex tasks. Since manual obviously hassle for user, ambient struggle automate process applying methods. The approaches have been adopted during last years vary many aspects, like domain application, modeling services, method, knowledge representation interfaces. work view revealing similarities differences, while providing additional information.
