Service Description And Discovery Based On Pay-as-you-go Fashion In Education Cloud

Application of education cloud services is a new direction of education informatization construction in our country,on the one hand,the education of cloud services can through provide a rich education teaching resources,improve the network interaction and improve the quality of teaching;On the other hand,it can use of the resources available,reduce the cost of education.Now,The education cloud services must be have a schema then supplied sever,so we need a new skills,in this paper,we research of “Service description and discovery based on pay-as-you-go fashion in education cloud”,my work in follows:1.Introduces the research status of education cloud services and the main education service description and discovery of cloud,it puts forward the schema of pay-as-you-go education cloud service descripttion and discovery that this method is not like the traditional schema,the data integration first,to provide users with services,but increasees with the increasing need to be integrated.And for heterogeneous and dynamic education cloud service information can effectively dealt with.2.An education cloud service entities and their logical relation described as a series of view resources and reasonable deal with the heterogeneous data,and later in the query,view resource internal relations can return the query results quickly.3.On the basis of view resource,with the study of the semantic of the keyword to add,the result of semantic discovery is rich,solved the keyword query results redundancy,low accuracy of defects.At last,to improve the accuracy of the query,the range of query is expanded in the service semantics;As education cloud service discovery continues,information system integration services by "incremental" mode,more content be added.The same time,in order to further improve the quality and efficiency,we added the service semantics.The experimental results show that the service description anddiscovery based on pay-as-you-go fashion in education cloud can be effectively applied in education cloud services,and compared with the traditional schema,the recall and precision comparison,its quality and the speed has the obvious improvement.
