A Method for Establishing Multi-dimensional Semantic Model of Web Services

Abstract

The invention relates to the technical field of web services and aims to provide a web service multi-dimensional semantic model, achieve semantization of web services, and increase availability of a web service semantic descriptive model. According to the technical scheme, a model building method includes: 1, defining functional semantics of web services according to MSDL standards; 2, defining context semantics of web services according to the MSDL standards; 3, defining performance semantics of web services according to the MSDL standards and describing quality attributes of the services; 4, defining technical semantics of web services according to the MSDL standards; 5, defining interaction semantics of web services according to the MSDL standards. The method is mainly applied to web services.

Description

technical field [0001] The invention relates to the technical field of Web services, in particular to a method for establishing a multi-dimensional semantic model of Web services. 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. [0003] In order to make Web services an entity understandable by computers, Semantic Web services, which describe service functions in combination with Semantic Web and other technical means, emerged. It aims to make the automatic discovery, selection, combination, verification and execution of Web services possible. In order to realize Semantic Web Services, on the one hand, the research is dedicated to the semantic extension of existing grammar-based Web services, trying to extract semantic information from existin...

AI Technical Summary

Problems solved by technology

At present, the research results of semantic automatic annotation have improved the efficiency of service discovery and combination to a certain extent, but with the continuous increase of services, due to the limitation of domain ontology, a large number of services will not be able to find suitable annotations in the process of semantic similarity matching

[0007] 2) Most of the existing Web service semantic description languages ​​have abandoned the structure of the traditional Web service language WSDL, but the Web services published on the Internet are mainly based on WSDL descriptions. Although the existing Web service description specifications propose a new The Web Service Description Language, which greatly enhances the semantic information of Web services, but does not propose a corresponding method to bridge the difference between the WSDL language and the semantic Web service 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.

[0009] 4) The existing semantic Web service models only consider the semantics of individual Web services, and most of them only consider the functional needs of users, without comprehensively considering the semantic features of Web service interaction, time and space, and context
