Abstract

The embodiment of the invention provides a web service composition method and system. The method comprises the following steps: conducting visualized design to base service so as to form the visualized element of the base service; mapping the visualized element to the ontology relational algebra expression; analyzing the ontology relational algebra expression so as to obtain each ontology and ontology relationship of the ontology relational algebra expression; finding the ontology corresponding to the analyzed ontology in a preset domain ontology library, and searching the service corresponding to the analyzed ontology relationship in the preset domain service library; and conducting automatic packaging to the searched service according to the relationship the ontology relational algebra expression reflects so as to generate the service flow chart. According to the web service composition method provided by the embodiment of the invention, the mapping relationship between the service and the ontology relation can be simply and directly built, so as to facilitate conducting service library-oriented service combination by combining semantic service search method.

Description

technical field [0001] The present invention relates to the technical field of web services, and more specifically, to a method and system for combining web services. Background technique [0002] In recent years, with the development trend of Web resource distribution from centralized to distributed, Web Service (Web Service) technology, as a new distributed computing model, has been widely used in research and application. However, in practical applications, although users can use a single Web service to extract the required information from public and commercial resource libraries, it still cannot meet the requirements of loose coupling and high cohesion of software entities. Therefore, it is necessary to combine multiple Web services to form collaborative work among multiple services to improve service reusability. At the same time, in the face of increasing Web services in various fields, more urgent requirements are put forward for service composition methods. [000...
