Service assembly system and method based on service quality optimization and semantic information integration

Abstract

The invention discloses service assembly system and method based on service quality optimization and semantic information integration, which are designed mainly for improving the reliability and stability of service assembly and service quality. The service assembly system comprises a Web service network, an ontology concept network database, an index generating server, a service assembly engine server and a service assembly result executing server, wherein the Web service network provides service and a corresponding input / output data type; the ontology concept network database provides an ontology concept; the index generating server is used for establishing a service-data type-ontology index between the input / output type of the service and the ontology concept and storing the index in the index generating server; and the service assembly engine server is used for receiving the input / output data type demanded by the client end, inquiring the data type matched with the input / output data type from the service-data type-ontology index and carrying out service assembly according to a service assembly algorithm to obtain a service assembly result. The invention integrates semantic information, has optimal service quality and can efficiently process large-scale service assembly.

Description

technical field [0001] The present invention relates to the technical field of Web services and service assembly, in particular to a service assembly system and method based on service quality optimization and semantic information integration Background technique [0002] With the popularity of Internet communication technology and e-commerce applications, service-oriented architecture (Service Oriented Architecture, SOA), that is, the idea of ​​software design with service as the core, is widely used in the construction of actual large-scale systems. In recent years, as Web services are used by more and more people, many business modules need several services to cooperate to complete, which creates a demand for service assembly technology. The so-called service assembly is to automatically combine several services related to business logic in a certain way to fulfill specific user needs. Web service assembly process refers to the process that service assemblers use assembl...

Problems solved by technology

[0004] In the software design and development under the SOA framework, the workflow is usually determined by the functions provided by the service. This is a bottom-up process. Accurate predefined workflow; secondly, in the process of service discovery, the list of candidate services is actually randomly generated, and the data size is relatively large

Lack of efficient service discovery algorithms

In addition, in the industry, the method of automatic service assembly is not widely used, the candidate service list is specified by the system developer, and the number of services is very limited

The fixed workflow also makes the service assembly process inflexible

[0005] In the process of service assembly, the traditional service assembly uses the input / output data type and name of the service for matching. The disadvantage of this is that the matching accuracy and coverage are very low

First of all, many service description documents (WSDL, Web Services Description Language) are automatically generated, and parameter names do not contain information, so there will be cases where they cannot be matched or matching errors occur; secondly, parameters named using natural language , there are also a large number of polysemy or synonyms. Due to the lack of information, the matching principle can only be limited to string matching, which will also lead to wrong matches or missing correct matches.
