A method and a system of spervised web service finding based on attribution forecast and error correction of quality of service (QoS)

Abstract

The invention discloses a method and a system of supervised web service finding based on attribution forecast and error correction of quality of service (QoS). The method and the system of the supervised web service finding based on the attribution forecast and the error correction of the QoS are mainly used for solving the problem of accurately effectively finding a credible web service meeting requirements of a user in an opened network environment, and therefore providing important technology support for the construction of a highly-credible service application system. On the one hand, the method and the system of the supervised web service finding based on the attribution forecast and the error correction of the QoS adopt a matrix compensation technology to carry out forecast or correction of the attribution of the QoS of the deficient or anamorphic services to enable the credible services based on the attribution of the QoS to be effectively implemented, on the other hand, prior class information of the services is introduced into the characteristic extraction stage indicated by the services to enhance distinguishing capability and query matching accuracy which are indicated by the services. Indicated by an evaluation result of a real web service data set, the method and the system of the supervised web service finding based on the attribution forecast and error correction of the QoS are not only high in efficiency and accuracy of service finding, but also simple to achieve, capable of enabling a system to be flexible, low in cost, and easy to popularize.

Description

technical field [0001] The invention belongs to the field of Web services, and mainly realizes a supervised Web service discovery method based on QoS attribute prediction and error correction and a system constructed by the method. Background technique [0002] With the increasingly widespread and deepening application of Internet technology, people are no longer satisfied with simply using network resources, such as browsing the web, sending and receiving emails, etc., but on the one hand hope to be able to simply and quickly publish the software resources they develop on It can be reused by others on the Internet. On the other hand, it is also hoped that the existing software resources can be reused conveniently to meet their individual needs. Software as a service is an effective way to realize the reuse of software resources, and the service-oriented architecture (Service Oriented Architecture, SOA) provides theoretical support for software as a service, which largely pr...

Problems solved by technology

This mechanism does not use the existing service category label information. Even if the extracted feature vector can express the semantic information of the service well, due to the lack of class discrimination information, the extracted high-dimensional feature vector will be in the feature space. Convergence and become inseparable, which is obviously not conducive to service discovery and lookup
