The Design And Implemention Of IoT Service Knowledge And Semantic Annotation

Things in the field of industrial fragmentation.Because of the construction of the duplication of the situation is serious,a large number of IoT system's application development is in a low level and the system is highly overlapping,so we're lack of a common technology platform.As a result,the mechanism of Internet of things has attracted more and more attention.Many researchers are pay a lot of attention to this,wanting to solver this problem and optimize the situation through the modeling of services so as to realize the integration of the physical world and enterprise services.In this paper,according to the ontology theory,which is defined and established by W3C,the features of the IoT and the future,the service description model based on ontology is built.A IoT knowledgebase is also built based on the ontology model built in this paper.Then,based on this,a standard of service classification is also established.The semantic annotation based on this service model is also realized.And we'll verify the model in a IoT access and management platform.The main work involved in this paper is as follows:(1)Make research on current service models,such as the OWL-S service model,WSMO service model and WDSL-S service model.And combine with the future development,establish a service model based on ontology,which describes the unified service description.Based on the ontology model,a IoT service knowledgebase is established.(2)Analyze the characteristics of the Internet of things detailedly,and propose a classification standard of the IoT service.(3)Realize the semantic annotation of services,laying the foundation of the semantic Web.(4)Vertify the availability and rationality of the service model through a IoT access and management platform.
