摘要:

传统的Web服务描述语言(WSDL)无法合理刻画数量不断增加且动态改变的传感网服务,导致具备相似输入输出接口的传感网服务不能被区分且服务存储与搜索负担日益加重,对此,提出在WSDL语法框架上扩展基于逻辑表达式的服务输入输出关系,融合Google语义距离和Levenshtein编辑距离计算服务相似度,并在此基础上定义服务输入输出匹配等级. 实验结果表明,通过对服务输入输出关系的语义扩展,能有效地提高传感网服务的检索和选取效率.

Abstract:

The traditional web service description language (WSDL) is limited in describing the increasing and changing of dynamic wireless sensor network (WSN) services. The services with similar input and output (IO) interface cannot be distinguished, and thereafter the burden of WSNs for service storage and retrieval is increased. To solve this problem, the WSDL is extended with a service IO relationship characterization based on the logic expression. Accordingly, a service similarity calculation based on Google semantic distance, Levenshtein edit distance and a service IO match algorithm are proposed. Experiments show that the proposed approach can effectively distinguish the services with similar IO and accordingly improve service retrieval efficiency in WSNs.
