将物联网中的设备、物体、传感器等接入语义网是一项严峻的挑战,为解决开发物联网应用时海量设备数据所带来数据整合问题,提出了一种基于语义标注与推理的物联网应用系统框架.框架中包含一种通用的物联网应用本体,在重用传统设备描述本体的基础上拓展了设备间关系的建模.框架还借助语义传感网、语义web和推理技术以支持可自动执行复杂分析控制任务的实际物联网应用的开发,如异常诊断、自动控制等.楼宇自动化场景下的实验结果表明,该框架支持物联网设备知识库的构建和扩展,并可以支持复杂的物联网应用.
Sending devices, objects and sensors in IoT into Semantic Web is a serious challenge. To solve the problem of data integration brought by massive device data in the development of IoT, a semantic annotation and reasoning based object Networked application system framework.The framework includes a common IoT application ontology, which extends the modeling of the relationship between devices based on the reuse of traditional device description ontology.The framework also supports the use of semantic web, semantic web and reasoning technology It can automate the development of practical IoT applications such as anomaly diagnosis and automatic control for complex analysis and control tasks.Experimental results in the building automation scenario show that the framework supports the construction and expansion of IoT device knowledge base and can support complex Internet of Things applications.
