> 中文摘要: 普适计算环境的服务对用户来说是透明的,为了简化用户与环境的交互,提出了一种目标驱动的服务组合方法,建立面向任务目标的服务语义表示模型,并在此模型下进行动态的目标驱动的服务组合,实现用户目标.描述了一个模拟的应用场景,并结合应用场景说明了任务定义和服务组合的过程.该方法简化了用户与环境的交互,提高了普适环境下服务组合和协同的灵活性.

Abstract:The pervasive computing environment is transparent for users. In order to simplify the interaction between users and the environment, this paper presents a goal-driven approach of service composition. A task-oriented semantic representation model of Web services is built and based on this model goal-driven service composition is performed dynamically to achieve user’s goal. A simulated application scenario is described and the process of task definition and service composition according to the scenario are discussed in this paper. This approach simplifies the interaction between users and pervasive computing environment and improves the flexibility of service cooperation and composition in the environment.
