摘　　要：基于pay-before-you-go模式的教育云服务描述与发现方法难以及时处理异构、动态的教育云服务信息,为了解决上述问题,提出基于pay-as-you-go模式的教育云服务描述与发现方法。首先采用数据空间渐进式模型描述服务信息,然后探讨服务发现中的延迟计算方法,最后通过添加语义扩展查询规模。实验结果表明,该方法是可行和有效的,并且提高了查询结果的查全率与查准率。Service description and discovery based on pay-before-you-go fashion was difficult to process heterogeneous and dynamic service data in education cloud.To solve the problem,this paper proposed a method of description and discovery in edu-cational cloud services based on pay-as-you-go fashion.Firstly,it used incremental model of the dataspace to describe service information.Secondly,it discussed the delay calculation method in service discovery.Finally,it added service semantics to improve the accuracy of query.Experiments show that this method is feasible and effective,and it can improve the recall and precision of query results.
