提出了基于语义和语法的服务检索方法.采用语义相似度的方法对服务进行管理,以达到提高检索效率的目的;采用语法结构的方式,利用命题库模式对服务建模并提出检索算法,以提高服务检索的精确率.以响应时间、召回率、精确率、综合评价指标为衡量指标,通过实验说明了结合语义和语法的检索方法的有效性. This paper proposes a service retrieval method based on semantics and grammar, and uses semantic similarity to manage the service in order to achieve the goal of improving the retrieval efficiency. Using the syntactic structure, this paper uses the proposition library model to model the service and proposes the retrieval algorithm Improve the accuracy of service retrieval.According to the response time, recall rate, accuracy and comprehensive evaluation index as the measurement index, the effectiveness of the retrieval method combining semantic and grammar is demonstrated experimentally.
