Embodiment Construction

[0057] The core idea of ​​the present invention is: introduce QoS ontology to describe QoS information, and expand the QoS ontology that describes QoS information; Adopt QoS comprehensive similarity based on semantic matching to represent the similarity and correlation degree between QoS information, fully Utilizing the semantic factors in QoS information, it can handle heterogeneous QoS information, and increases the flexibility and accuracy of Web service selection.

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0059] Such as figure 1 As shown, a QoS ontology-based Web service selection system includes: a QoS ontology extension unit 1 , a QoS request vector formation unit 2 , a QoS advertisement vector formation unit 3 and a Web service selection realization unit 4 . Among them...

Abstract

The invention discloses an Internet (Web) service selection system based on a service quality (QoS) body. The system comprises a QoS body expansion unit, a QoS request vector composition unit, a QoS advertisement vector composition unit and a Web service selection realization unit; the Web service selection realization unit is used for obtaining and calculating the QoS information comprehensive similarity degree between QoS information in a QoS request vector and QoS information in a QoS advertisement vector, and being matched with the demands of a service request terminal and services provided by a service provision terminal. The invention also discloses a Web service selection method based on the QoS body, and the method comprises the following steps: obtaining and calculating the QoS information comprehensive similarity degree between the QoS information in the QoS request vector and the QoS information in the QoS advertisement vector, and being matched with the demands of the service request terminal and the services provided by the service provision terminal. The needs of Web service selection based on semantics can be satisfied by adopting the system and the method.

Description

technical field [0001] The invention relates to Internet (Web) service selection technology, in particular to a Web service selection system and method based on Quality of Service (QoS) ontology. Background technique [0002] With the rapid development of the Internet, the application of the network has penetrated into many aspects of society. The services available on the Web have increased dramatically, and the information on the Internet has grown exponentially. Maintenance becomes increasingly difficult. How to effectively obtain the required functional Web service from the huge service group and how to find the most satisfying service among the similar functional Web services have become issues worthy of attention, and these are the tasks of Web service selection. Web service selection technology refers to: According to the QoS information of Web services, select a Web service that best meets the individual needs of service requesters in terms of Qos from many Web serv...
