基于觉察上下文计算的健康智能家庭研究

摘要

On HSH based on context-aware computing is researched, and context modeling and context reasoning of HSH is mainly researched, and an experimental system--AngelHome is set up. First of all, analysis the context of the HSH, and then use Ontology to model, describe by OWL DL language, and present an AngelHome ontology. A hybrid context reasoning framework is presented, the framework includes three methods: ontological reasoning, rule-based reasoning, Bayesian network reasoning, the three methods are apply in different task, they cooperate mutually. AngelHome bases on OSGi framework, it has a good flexibility. Next, analysis the main parts of the system, and test it. Experimental results show that context-aware computing used to achieve HSH is feasible.%利用觉察上下文计算技术来研究实现健康智能家庭,主要研究了健康智能家庭的上下文建模和上下文推理,并构建了一个实验系统AngelHome,分析了健康智能家庭中的各种上下文信息,利用本体技术对其进行建模,并用OWLDL语言表达上下文信息模型,构建了AngelHome本体;在上下文推理部分采用混合推理,对不同的推理任务分别采用本体推理机、自定义规则推理机和贝叶斯神经网络推理.AngelHome采用OSGi框架,具有良好的伸缩性,这里分析了系统的几个主要部分,并进行了测试.实验结果表明,利用觉察上下文计算技术来实现健康智能家庭是可行的.
