情境感知技术是普适计算研究的重要方向，而情境推理是情境感知系统的核心部分。针对目前智能空间中情境推理方法存在的推理实现便捷性和满足应用特殊要求难以兼顾的问题，对基于相似度计算、基于多值逻辑、基于规则和基于本体等主流情境推理方法进行了优缺点分析，在此基础上提出了一种基于本体和自定义规则的情景推理方法。利用一阶谓词逻辑对情境信息进行描述，选择Jena作为情境推理的工具，并对情境推理的实现流程进行了详细讨论。以智能家居应用场景为例验证了该方法的有效性。
情境感知技術是普適計算研究的重要方嚮，而情境推理是情境感知繫統的覈心部分。針對目前智能空間中情境推理方法存在的推理實現便捷性和滿足應用特殊要求難以兼顧的問題，對基于相似度計算、基于多值邏輯、基于規則和基于本體等主流情境推理方法進行瞭優缺點分析，在此基礎上提齣瞭一種基于本體和自定義規則的情景推理方法。利用一階謂詞邏輯對情境信息進行描述，選擇Jena作為情境推理的工具，併對情境推理的實現流程進行瞭詳細討論。以智能傢居應用場景為例驗證瞭該方法的有效性。

Context-aware technology is an important research direction of pervasive computing,and context reasoning is the core of con-text-aware systems. In view of the existing context reasoning method is difficult to fulfill the convenience of reasoning to realize and meet the application requirements in intelligent space simultaneously,based on the analysis of advantages and disadvantages of mainstream con-text reasoning methods at present such as those based on the similarity calculation,based on multi-value logic,based on rule reasoning and based on ontology,a context reasoning method based on ontology and user-defined rules is proposed. Then the first-order predicate logic is used for the representation of context. Jena is chosen as the context reasoning tool,and the realization process of context reasoning is discussed in detail. The effectiveness of the method proposed is verified under the environment of intelligent home.
