Semantic operation composition according to user tasks in ubiquitous environment
Article No.: 74, Pages 1 - 7
Abstract
This paper presents the operation composition method based on Service Component Architecture (SCA). Applying semantic factors to this method has revealed the automatically discovered and composited operations corresponding to user demands. We first introduce the several ontologies used by our method. The first issue is how to represent user's requirement in a ubiquitous environment. The second topic is service discovery. In order to achieve the goal of service discovery, sometimes it is necessary to combine more than one service. To address this problem, many service matchmaking algorithms are proposed. However, most of these deem that a service is equal to a single functional unit or several separate units. In fact, a service may contain several functional units, which are not separate from each other. Some implied relations may exist among the functional units so that they can be composed to provide new functions. Based on this observation, we propose a semantic operation composition method, which is determined mainly by user-defined task structure. This method has been applied in a service composition framework called WSUN.
