Through the rapid development of ICT, things are becoming connected with each other through the Internet. The Internet of Things is a key technology for constructing such a connected society. Currently, autonomous management technology in an IoT-based network is developing in various ways. However, the existing technology that recognizes and manages the fault situation by monitoring information through policy has limitations in recognizing the network situation. In this paper, to solve this problem, a Fiesta-IoT ontology model and semantic analysis technology are used to recognize various situations of network disturbance. We tried to solve the interoperability problem by using the OCF standard resource model. To this end, we propose a semantic analysis system that can recognize the status of the network from various perspectives by extending the information about devices based on the relationships between the devices that constitute the IoT network, as well as an error-detection algorithm for anomalous states that can use semantic analysis to detect whether a node receives an abnormal sensing value. We also develop a semantic analysis system based on the proposed structure and introduce the results of implementing a prototype.
