Automatic service combination system and method based on semantics

Abstract

The invention relates to an automatic service combination system and method based on semantics. The system comprises a server terminal and a client terminal. The server terminal comprises a database constructing module, an automatic workflow generating module, a service discovering module and a service combination module. The client terminal comprises a requirement semantics inputting module and a display module. The method includes the following steps that according to input requirement semantics, a domain library and a behavior library; workflow is automatically generated; fine adjusting is carried out on the generated workflow; according to the workflow and the semantic information of a service, a candidate service set is obtained through calculation of semantics similarity; according to QoS information of the service, an executing path which can meet the QoS constraint of a user and has the optimal QoS property is chosen. Authentic automatic evolution growth of complicated software is achieved in a large scale, the workflow is provided without need of manual intervention and the service combination efficiency is extremely improved.

Description

technical field [0001] The invention relates to a semantic-based automatic service combination system and method, belonging to the technical field of computer Internet. Background technique [0002] With the rapid development of the Internet industry, more and more online business solutions have been proposed. However, any service can only meet a relatively single customer demand. Service providers eagerly hope that existing services can be conveniently combined into more powerful value-added services to meet more diverse needs, so people put forward the concept of Web service composition. At present, there are two types of methods for automatic service composition: one is to use workflow, and the other is to use AI planning. The current methods of utilizing workflow all assume that the workflow is given by the user, and cannot complete the automatic generation of the workflow. [0003] Further searching found that Chinese Patent Application No. 201110051185 discloses a s...

Problems solved by technology

[0006] The technology of the present invention solves the problem: In order to solve the problem that the workflow cannot be automatically generated and needs to be provided by the user, a semantic-based automatic service combination system and method are provided to realize the automatic generation of the workflow, so that the generation of the workflow does not require manual intervention to provide work flow, greatly improving the automation efficiency of service composition
