Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the current measurement method of service combination results cannot handle the usability of sub-services, and cannot evaluate the matching degree of combination results in terms of sub-service associations and functional structures with user requests. Analyze the relationship and functional structure of services, and propose a composite similarity measurement method for the composition results of semantic Web services

Embodiment Construction

[0034] The above content has fully disclosed the present invention, and the implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited to this.

[0035] This example transforms the service composition result into a directed hierarchical graph, as shown figure 1 Shown, where,

[0036] The boxes represent the sub-services in the service composition result;

[0037] The circles represent the input, output, pre-condition and post-condition information of the sub-service. The circle above the box is the input list of the sub-service; the circle in the lower half of the box represents the output list of the sub-service; the circle on the left of the box represents the pre-conditions of the sub-service; it is located on the right of the box The circle on the side represents the post-condition of the sub-service.

[0038] The associated directed ed...

Abstract

The invention provides a complex similarity measurement method of semantic Web service composition results, which comprises the steps of showing the composition results obtained by a semantic Web service composition method with a directed hierarchy chart, analyzing a satisfactory situation of a input list of each sub-service according to the obtained directed hierarchy chart, judging the usability of the sub-services to obtain the performability of the sub-services and the composition results, analyzing the purpose of each output of each sub-service according to the obtained directed hierarchy chart, obtaining importance factors of the outputs for different purposes through analysis by an artificial intelligence method to calculate the weight of each sub-service, proposing a calculation method of association similarity of the sub-services according to the weights of the sub-services and the concept similarity of an IO (Input / output) association relationship, calculating the association similarity of the target outputs with the calculation method of the association similarity, and calculating a matching degree between the obtained composition results and a user request with the number of the sub-services in the composition results to ensure that a user can make an option on the service composition results.

Description

Technical field [0001] The invention belongs to the technical field of semantic Web service composition, and specifically relates to a method for measuring the conformity similarity of the result of semantic Web service composition. Background technique [0002] Semantic Web service composition methods are divided into: business process-driven semantic Web service composition and instant task-solving semantic Web service composition: (1) The workflow-driven service composition method uses workflow as the basic model to achieve semi-automatic service composition. Fixed process restrictions, unable to meet the needs of dynamic processes; (2) According to the user's service request, several services are selected for automatic combination in real time. There are three main categories: based on Petri net, based on AI theory and search based on graphs, but none of them Deal with complex relationships between sub-services. In the choice of the basic model of the combination algorithm, ...
