Problems solved by technology

[0007] In order to overcome the problems of incomplete consideration and poor effectiveness of existing Web service evaluation methods, the present invention proposes a more comprehensive and effective Web service comprehensive score calculation method based on OWL-S. An extension of OWL-S based on ontology, which adds non-functional description (QoS) to Web service description, making the service more comprehensive

Embodiment Construction

[0104] The present invention will be further described below in conjunction with the accompanying drawings.

[0105] refer to figure 1 , a method for calculating the comprehensive score of Web services based on OWL-S. The calculation of the comprehensive score of the service needs to be calculated by weighting the QoS score and the functional similarity (the result of the functional similarity measure), where the functional similarity measure considers the input and The domain ontology concept of the output, the matching between the input (output) mainly refers to the matching of concepts related to the input (output). In order to calculate the similarity of two concepts A and B, the relationship between the two concepts in the domain ontology needs to be considered.

[0106]A domain ontology is a specialized ontology that describes the knowledge of a specified domain. The "domain" here is established according to the needs of the ontology builder. It can be a subject domain,...

Abstract

An OWL-S-based method for calculating the comprehensive score of Web services , includes the following steps: first, calculating the semantic similarity between two concepts A and B in the domain ontology; 2, giving a method for calculating the input similarity degree Simput of the service S1 and the service S2; 3, giving the calculation method of the output similarity Simoutput of the service S1and the service S2; Fourth, calculating the functional similarity FunctionalSim (S1, S2) between the service S1 and the service S2; 5, calculating weights of QoS attributes set by users; 6, verifyingthe consistency of the user judgment according to the paired comparison matrix A constructed in the fifth step and the weight vector W obtained in the fifth step; 7, calculating the weighted result ofthe QoS score and the functional similarity to obtain the comprehensive score result of the service. The invention has more comprehensive consideration angle and better effectiveness.

Description

technical field [0001] The invention relates to the field of Web service matching, in particular to an OWL-S-based calculation method for comprehensive scoring of Web services. Background technique [0002] A web service is a software system designed to support cross-network interaction between machines. There are currently two main types of Web services: one based on SOAP and the other based on REST. The difference between the two is the different interfaces used. SOAP-based Web services use SOAP interfaces to transmit messages, and use Web Services Description Language (WSDL) to describe Web services. WSDL specifies the use of protocols and encoding independent mechanisms for Web service providers. It is an XML vocabulary that describes services accessible on the network and maps them into a collection of communication endpoints with messaging capabilities. Web services using REST interfaces use common HTTP methods (GET, DELETE, POST, and PUT) to describe, publish, and c...
