随着网络技术的发展和移动设备的广泛的应用，情境感知服务已经成为了近年来一个研究热点。利用语义网技术，文章提出了一个基于规则的情境感知信息推送架构。架构的核心模块是一个相关性判定规则引擎，能够通过执行不同的规则集，对系统的行为进行配置。定义了基于本体的情境模型组织来自不同信息源的情境信息，并表示出用户的情境特征。定量的评估结果表明，该架构具有一般性和自适应性，能够为移动警察推送支持其正确行动和决策的信息。

Current web service technologies together with the advances in mobile devices have significantly increased the development of context-aware services. Relying on the Semantic Web technologies, this paper offers a rule-based architecture supporting delivery of contextualized information. The core functionality is fulfilled by the relevance assessment rule engine, which can re-configure the behavior of the system by specifying the different rule sets. It defines an ontology-based context model, which formalizes the context from different information sources and characterizes the contextual situations of mobile users. Qualitative evaluation results that the architecture has the generality and adaptability; thus can assist mobile police to take decisions during their activities.
