Cloud service discovery and key matching methods in the semantic internet of things

Abstract

The nature of the Internet of things is the Internet connected by objects and things, which is a bridge to realize the seamless link between the physical world and the information world. But the diversity of the object information and the lack of understanding of the main body can not make the data perceived by the Internet of things meet the needs of the information world, which hinder the development of the Internet of things. Advanced applications and services require explicit semantic knowledge, so the Internet of things requires the support of semantic technology. This paper gives the main framework of cloud service discovery method in semantic Internet of things, and puts forward the technical support of cloud service discovery method based on intelligent algorithm. Firstly, the ontology of cloud computing involved in the discovery process is built by referring to the mutual constraints in cloud services and obtaining common knowledge in the field of cloud computing. Secondly, the different matching methods are proposed for the matching of services under different circumstances. Finally, the evaluation method of query results is designed in detail.
