Semantic annotation method of IOT middleware

This paper puts forward a general middleware framework of the Internet of Things (IOT). This framework has distributed, loosely coupled, scalable features. To solve the problems of machine processing of messages of IOT, the concept of ontology is introduced. The proposed algorithm can quickly classification and annotation of user demand, web services and resources data. In addition, the algorithm has good scalability. It can be applied to different fields only what people need to replace the domain ontology.
