Abstract: Leveraging Service-Oriented Architecture(SOA) and reasoning techniques based on production, this paper proposes a rule-driven adaptive context-aware computing model. Production is used as semantic basis to model and represent user’s requirements and service composition policies. During the runtime, the reasoning engine automatically specifies service components for the satisfaction of preloaded goals depending on changing availability of resources in dynamic ubiquitous environments.

Key words: context-aware computing, Service-Oriented Architecture(SOA), production, adaptation

摘要： 以面向服务的体系结构和产生式推理技术为基础，提出一种规则驱动的自适应觉察上下文计算模式。在该模式中，用户的需求及服务复合策略的语义用产生式表示。在动态普适计算运行环境中，规则推理引擎能够在运行期间，根据当前的上下文知识自动选择服务构件，动态合成应用软件完成预定目标。
