Web service combination system and method

Abstract

The invention provides a Web service combined system. A service combined bus is established in the system; each combined part establishes communications through service combination; each combined part comprises a service demander, a service provider, a combined agent and a combination evaluator; and the service combination bus establishes a two-dimensional theme event matrix and delivers theme events related to the service combination among each combined part on the basis of the two-dimensional theme event matrix through a subscribe/publish mechanism and a request/reply mechanism. The invention further provides a service combined method which ensures that four phases of service combination are completely realized, so that an overall support from user demand to final combination result is realized. The invention is particularly suitable for supporting competitive bidding of a multiple combination agency; each combined party can know problems well in time in the combination; and the mix strategy can be adjusted in time, so as to help to improve the combination quality greatly and obtain a combined service with a highest performance-to-price ratio.

Description

technical field [0001] The invention belongs to the technical field of Web services, in particular to a Web service combination system and method. Background technique [0002] Web service is an intelligent body and information body distributed on different nodes of the network, especially the Internet. It is an extension and development of component technology. It establishes a standard mechanism based on standards that enables applications to be accessed across system architectures and platforms. [0003] Web service composition refers to the use of existing Web services to automatically select multiple Web services that meet the needs according to the user's application requirements, and to form a new and more powerful Web service under certain rules. The combined Web service must not only meet the requirements in terms of function, but also some other special service elements, such as cost, expenditure, running time, etc., may be required, that is, service quality requir...

AI Technical Summary

Problems solved by technology

[0006] (1) It only involves the development level, that is, the stage of combination and verification, and basically does not involve other stages, which is not conducive to users' convenient combination requirements and timely tracking and grasp of combination dynamics;

[0007] (2) There is no effective means to enable the parties involved in the combination to interact;

[0008] (3) The completion of a service combination usually requires a cycle of requirements, combination, evaluation, improvement, etc., and the above results lack support for this cycle
