摘要: 语境信息是用来刻画一个实体情形的信息,该文提出了基于本体的语境信息建模以及查询方法,利用本体极强的语义描述能力和有效的推理机制,更好地实现了语境信息的管理。介绍了关键技术、相关支持工具以及开发的原型系统。该模型采用2种推理机制:基于描述逻辑的推理与规则推理,能够更快速有效地管理语境信息。

Abstract: Context information describes the details of entity and situation. This paper introduces a comprehensive and formal ontology-based model and reasoning mechanism. The implementation of context ontology enhances the expressiveness, support inference, thus can improve the management of context information. The key method, supportive tools and prototype systems are introduced. The main benefit of this model is the ability to reason over context data by two ways: description logics and rules, which can improve the context information management.

Key words: ubiquitous computing, context-aware, description logic(DL), ontology, RDQL
