中文摘要：

智能环境具有预感知能力,为用户提供主动的智能服务.文中采用基于规则的推理技术有效解决了上下文推理方法中描述能力差和不确定性的问题.这种推理机制的结构接近于人的思维和自然推理形式,易于实现人机交互,符合人们的认知规律和行为习惯.深入论述基于规则的Jena推理机后,在智能家庭原型系统中验证了其可行性和有效性.

英文摘要：

Smart space can provides users with active intelligent services due to its capability of pre-apperceive. By adopting the rules-based reasoning technique, this paper resolves efficiently the issue that insufficient description capability and uncertainty in the context reasoning method, the framework based on reasoning mechanism is close to the thinking pattern and inherent reasoning mode of people, is apt to realize the interaction between man and machine, and accords with the cognize disciplinarian and behavior habit of people. This paper introduces the investigation on Jena reasoning machine based on rules, and validates its feasibility and efficiency depending on the prototype of smart home.
