Service neighborhood based Web Service quality prediction method

Abstract

The invention relates to the field of web service quality prediction, and discloses a service neighborhood based Web Service quality prediction method. The method is characterized by including the following specific steps of similarity calculation, neighbor selection, model establishment, model solution and prediction. A prediction model obtained by neighbor user based feature vector learning is established, and is solved through a gradient iteration descent method, and finally a predicted value of web service quality of a target user is obtained. Meanwhile, the invention discloses a device applying the Web Service quality prediction method. The method and the device have the advantages that accuracy is high, the problem about prediction of web service quality in the cold boot process is solved by separating feature vectors of target services and feature vectors of neighbor services, and application value is high.

Description

technical field [0001] The invention relates to the field of web service quality prediction, in particular to a service neighborhood-based Web Service service quality prediction method, and discloses a device for applying the service neighborhood-based Web Service service quality prediction method. Background technique [0002] Web Service is a kind of application used to realize the interoperability and accessibility of resources on the network, and this kind of application is self-describing and programmable. Web Service is generally implemented using a standard well-defined language and published through a standardized protocol. Based on the SOA architecture, Web Service has become an important means of realizing information systems within and between enterprises. At the same time, because Web Service technology is widely used in cloud computing, especially on SaaS platforms, the number of Web Services is growing rapidly. [0003] Service quality is a general term for n...
