Web service relation network system based on semantic meanings

Abstract

The invention discloses a web service relation network system based on semantic meanings. Web service relation networks are used for the service discovery based on semantic meanings and the combination of semi-automatic or automatic service combination. The services to be processed by the web service relation networks come from submitted services and acquired services of the web service relation networks, wherein the submitted services passively receive service registration requests, extract information and send the information to the web service relation networks, the acquired services comprise descriptive files which actively acquire services through web crawler technology, the descriptive files are added to the web service relation networks through service registration interfaces, composite services which are automatically acquired are described according to functions of a user, and the composite services are sent to the web service relation networks through service registration. The web service relation network system based on semantic meanings is more convenient for the release of web services, the service discovery based on semantic meanings and the semi-automatic or automatic service combination, can expand descriptive languages of different services and can be compatible with the descriptive languages, organizes available web services into an ecological service system and improves the operation of services by means of relation among services, such as automatic combination, searching, maintenance, and the like.

Description

technical field [0001] The present invention relates to an Internet-based network system for describing and discovering services, in particular to a Web application-based service information organization method, such as registration, management, and access mechanisms. Background technique [0002] At present, the Web service registry often adopts UDDI-like standards, uses XML documents to describe enterprises and the Web services they provide, and maintains a global directory of Web services. This UDDI-based or variant-based Web service registration model has the following disadvantages due to the lack of semantic description of the relationship between Web services: [0003] 1) The registry only stores basic information such as the name and domain of web services, and can only discover and match services based on keywords, resulting in low recall and precision rates of web services; [0004] 2) Lack of description information on the semantic attributes of Web services, res...

AI Technical Summary

Problems solved by technology

[0003] 1) The registry only stores basic information such as the name and domain of web services, and can only discover and match services based on keywords, resulting in low recall and precision rates of web services;

[0004] 2) Lack of description information on the semantic attributes of Web services, resulting in the inability to realize service query through the semantic attributes of Web services in applications oriented to business process integration;

[0005] 3) Lack of descriptive information on the relationship between Web services, unable to provide a more flexible and usable service classification mechanism;

[0006] 4) The service discovery algorithm that focuses on functional requirements cannot meet the requirements of QoS;

[0007] 5) Lack of further support for automatic composition of Web services

[0008] At present, many studies are dedicated to correcting the defects of the existing UDDI registration model, such as using ontology technology to improve the recall rate, and using hash tables to improve search efficiency, but none of them fundamentally solve the above-mentioned problems faced by the current Web service registration model. main problem
