Dynamic service combination and selection method and system based on demands

Abstract

The invention discloses a dynamic service combination and selection method and system based on demands. The method includes the steps that a service request of a user is received and analyzed; an atomic service library is searched for multiple groups of initialization services matched with the service request and corresponding termination services according to an analysis result, each initialization service and the corresponding termination service form a service group, and the multiple groups of initialization services are sequentially numbered as 1, 2, 3, ..., n; as for the ith service group, the initialization service is taken out, and the atomic service library is searched for a follow-up service matched with the initialization service; whether the follow-up service acquired in the previous step is the termination service in the service group numbered as i or not, and if yes, a combination sequence Qi is acquired and added into a combination scheme set {S}, wherein the combination sequence Qi comprises the initialization service, the follow-up service and the termination service. The dynamic service combination and selection method and system based on the demands solve the problem that service quality of an existing service selection technology can not fully meet the individual demands of users.

Description

technical field [0001] The invention belongs to the field of information services, and more specifically relates to a demand-based dynamic service combination and selection method and system. Background technique [0002] With the development of the Internet and the integration of networks, there are more and more web services. At the same time, users have higher and higher requirements for services, and even hope to customize and generate services that meet their own needs. However, the functions provided by a single service are limited, and relying solely on service providers to design and develop new services is far from meeting the diverse and personalized needs of users. Therefore, it is necessary to combine existing web services and integrate existing multiple web services. Heterogeneous services are generated to generate new services that meet user requirements. [0003] Today's service composition research can be divided into two directions: academic research focuse...
