【摘要】：基于Web服务的网络管理技术应用中,把五大网络管理功能拆分成为一个个独立的服务后。服务数量大而且不同网络管理平台的服务中存在异构性,存在服务发现和服务复用的难题。服务描述是指对服务请求者的需求和服务提供者发布的服务进行统一的描述,以便于服务发现[1]。在服务描述中引入语义网(Semantic Web)概念,增加语义描述到网络管理的服务描述信息中,由于语义信息能进行逻辑推荐,使服务能被计算机所“理解”和“操作”实现服务的自动发现和组合。如何在网络管理领域利用语义Web Services技术,提高服务推荐能力成为了科研人员关注的重点。本文通过对服务描述信息的建模、存储,提供一种具备服务自动组合的语义Web服务推荐系统,旨在提高单服务匹配的准确性和满足用户对组合服务的需求。首先,根据现有的Web服务网络管理平台设计了服务描述信息模型包含服务基础信息和服务语义信息。其次,讨论了基于该信息模型的服务推荐方法,包括单服务推荐方法和技术和组合服务推荐方法和技术。最后,在传统的Web服务系统基础上设计语义服务推荐原型系统,即服务注册中心中增加语义匹配模块和服务组合模块,提供单一服务发现和组合服务发现功能。
[Abstract]:In the application of Web service-based network management technology, the five network management functions are divided into one independent service. The service quantity is large and the service of different network management platforms is heterogeneous. The concept of Semantic Web is introduced into the service description, and the semantic description is added into the service description information of network management. Because the semantic information can be logically recommended, the service can be "understood" and "operated" by the computer to realize the automatic discovery and composition of the service. How to make use of semantic Web Services technology in the field of network management to improve service recommendation ability has become the focus of attention of researchers. This paper provides a semantic Web service recommendation system with automatic service composition by modeling and storing service description information, aiming at improving the accuracy of single service matching and satisfying user-to-user composition. Firstly, according to the existing Web service network management platform, the service description information model is designed to contain the service basic information and service semantic information. Secondly, the service recommendation method based on the information model is discussed, including the single service recommendation method and technology and the composite service recommendation method and technology. Based on the service system, a prototype system of semantic service recommendation is designed, which adds semantic matching module and service composition module to the service registry to provide single service discovery and composite service discovery functions.
