摘要 情境感知系统可以在各领域异构资源和环境动态信息的情境本体协同构建中得到有效建立,为用户情境感知决策制定提供准确的服务。为此,本文根据概念格与情境本体内涵的相似性以及可集成实现的必要性、独特性和可行性开展系统分析,依据概念格可符合生命周期对系统这两类情境资源加以分布集成之功能,提出前者可在其概念格整合中立足于知识创造现实场景的立体化抽象得到领域情境本体建模和统一网络约束表示;后者可在情境感知中间件的人机交互认知识别中,通过领域情境本体的概念格解构及其与环境资源的“六何”感知关联重构,立足于用户应用实际情景的形象化塑造得到5Ws1H项表示的情境感知元本体建模和面向问题解决的实例化创建。以火灾应急领域情境本体向实施火灾救援的情境感知元本体进化为例加以分析,结果表明,情境感知系统能够在这种情境本体协同构建方法中得到有效建立,为用户情境感知决策提供准确服务。 To build a context-aware system(CAS) in the collaborative construction of context ontology(COnt) of heterogeneous resources and environmental dynamic information in various fields, it is essential to provide accurate context aware services for users’ decision-making. Therefore, based on the similarity of concept lattice and COnt, the necessity,uniqueness and feasibility of integrated realization, this paper theoretically distributes and integrates the two types of context resources of the system based on the context life cycle. It is proposed that the former can obtain unified domain COnt modeling and network constraint representation in the hierarchical structure of its concept lattice integration based on knowledge creation reality three-dimensional abstraction, and the latter can obtain the context awareness meta-ontology(CAMOnt) modeling and problem solving oriented instantiation creation in the human-machine interaction cognition of context-aware middleware based on visualization of the users’ actual application situation by the conceptual lattice deconstruction of domain COnt and its reconstruction through “5Ws1H” awareness association with environmental resources.Considering the evolution of fire emergency domain COnt to fire rescue CAMOnt as an example, the analysis shows that CAS can be effectively established in this COnt collaborative construction method and provides users with accurate context-aware services.
