摘　　要：针对智慧教室中物联网情境信息的多源异构问题,分析智慧教室及情境信息建模的研究现状,提出基于语义表达的智慧教室情境信息建模方法。通过传感设备和智慧教室管理系统获取智慧教室情境信息,基于时空关联算法过滤冗余信息并建立E-R概念模型,利用Protégé建模工具构建智慧教室情境信息本体。经过Racer Pro推理机的逻辑检测,清晰显示了智慧教室情境信息之间的语义关系,验证了该建模方法的有效性和可靠性。Aiming at the multi-source heterogeneous problems in the contextual information of the Internet of Things in smart classrooms,the research status of smart classrooms and contextual information modeling is analyzed,and a method based semantic expression for modeling contextual information of smart classrooms is proposed.The situational information of the smart classroom is acquired through the sensoring equipment and the smart classroom management system;the redundant information is filtered out and the E-R conceptual model is established based on the spatio-temporal correlation algorithm;and the context information of the smart classroom is constructed using the Protégémodeling tool.After the logic test of the Racer Pro inference engine,the semantic relationship among the contextual information in the smart classroom is clearly displayed,and the validity and reliability of the modeling method are verified.
