Web Service Selection Method Supporting Dynamic Correction of Preference Degree

Abstract

The present invention discloses a Web service selection method for supporting preference degree dynamic modification and belongs to the technical field of service selection. pruning a service list provided by a service provider by using a corresponding filtration rule according to the type of user demand detailed information to obtain a Skyline service set, ranking the Skyline service set by combining the expectation preference degree of a user for a selected service and using a weighing relative entropy to obtain a service ranking list, and dynamicly modifying the expectation preference degree of the user for the selected service according to the rank of the service selected by the user in the service ranking list and updating the service ranking list. The Web service selection method for supporting preference degree dynamic modification provided by the present invention solves the problem of low service selection efficiency on a large scale service set, difficulties of setting user preference in service selection and dynamic migration, and the like, optimizing the service selection process, provides guidance for user preference setting, makes the setting of user preference more reasonable and convenient, and provides a powerful method and tool for the service selection.

Description

technical field [0001] The invention discloses a Web service selection method supporting dynamic modification of preference degree, and belongs to the technical field of service selection. Background technique [0002] Against the backdrop of global economic integration and informatization progressing in depth, the software and information technology service industry is accelerating its evolution towards networking, service, systematization and integration.
