Web service transformation method from traditional web services to multi-dimensional semantic models

Abstract

The invention relates to the technical field of web services and aims to improve availability of semantic web service descriptive models and achieve semantization of existing WSDL-described web services. According to the technical scheme, the method includes the steps of 1, acquiring functional semantics from a WSDL-described service document; 2, acquiring context semantics from the WSDL-described service document; 3, calling a web service, defining performance semantics of the web service according to MSDL standards; 4, acquiring time-space semantics of the service from the WSDL-described document; 5, acquiring technological semantics of the service from the WSDL-described document; 6, defining interaction semantics of the web service according to MSDL standards. The performance semantics of the multi-dimensional model describes quality attribute of the service. The method is mainly applied to web service technologies.

Description

technical field [0001] The invention relates to the technical field of Web services, in particular to a method for transforming Web services from traditional Web services to multi-dimensional semantic models. Background technique [0002] Web service is an application program based on Web environment with self-adaptation, self-description, modularization and good interoperability. With the continuous increase of Web services on the Internet, a service-centric Internet is quietly forming. At present, most of the existing Web services are described using WSDL (Web Services Description Language). These traditional Web services lack sufficient semantic information, which affects the results of service discovery and service composition, and enables automatic service composition. difficulty. Therefore, it is necessary to add missing semantic information to existing Web services. [0003] In order to realize Semantic Web Services, on the one hand, the research is dedicated to th...

Problems solved by technology

[0006] 1) Existing methods for semantic extension of Web services are completely based on the architecture of traditional Web services, and the degree and ability of semantic extension of services are very limited. Most of the extension algorithms only increase the functional semantics of services, but lack other Aspect semantics, such as contextual semantics for services

[0007] 2) Although the existing Web service description specifications proposed a new Web service description language, which greatly enhanced the semantic information of Web services, they all abandoned the structure of the traditional Web service language WSDL, and did not propose corresponding methods to bridge the gap between the WSDL language and the Semantic Web Services language

[0008] 3) The existing semantic models of Web services are not unified, and there are differences in description methods

For example, due to the lack of common semantic constraints on Web services between service providers and between service providers and users, the interoperability between Web services and the efficiency of service discovery and composition are hindered.
