Embodiment Construction

[0029] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the semantic service automatic composition method of the service-oriented architecture of the present invention comprises the following steps:

[0031] S1. Build a basic development platform. The present invention is an open source development platform based on Eclipse built under the J2EE platform, and uses the open source software Struts as the presentation layer of the development platform, Spring as the business layer of the development platform, and Hibernate as the persistence layer of the development platform . Axis is used as the basic open source software for Web service development, Protégé is used as ontology-based semantic modeling, and OWL-S API is used as basic semantic reasoning, etc. MySQL is used as the data storage database and data warehouse of the development platform, Tomcat is used...

Abstract

The invention provides a semantic service automatic combination method facing to a service system structure with compact structure and semantics, which comprises the following steps: (1) establishing a universal and uniform service access model aiming at all World Wide Web sources; (2) extracting reasonable services from the uniform service access model; (3) gathering, classifying and identifyingthe extracted services; (4) converting the gathered, classified and identified extracted services; (5) loading the converted services; (6) finishing exchange, dispatch and distribution of the services; (7) carrying out mapping and matching of the services so as to precisely position required services; and (8) carrying out service combination and evaluation on the matched services so as to select a best service. Compared with the prior art, the method can automatically match, discover and dispatch Web services by utilizing the loosecoupling characteristics of the Web services and a semantic network to provide semantic information for the Web services so as to dynamically generate and execute a service flow and better realize the semantic service combination.

Description

technical field [0001] The invention relates to a service automatic composition method, in particular to a service architecture-oriented semantic service automatic composition method. Background technique [0002] Service-Oriented Architecture (Service-Oriented Architecture, SOA) refers to a software system architecture realized by connecting independent functional entities that can complete specific tasks in order to meet the needs of business integration. SOA is a component model that links different functional units of an application (called services) through well-defined interfaces and contracts between those services. The interface is defined in a neutral way, independent of the hardware platform, operating system, and programming language that implements the service. This allows services built into various such systems to interact in a unified and common way. The current service-oriented architecture mainly adopts Simple Object Access Protocol (SOAP), Web Services De...
