Problems solved by technology

However, there are few studies on the generation of service composition candidate sets. The generation methods of service composition candidate sets mainly focus on traditional web service composition, but this method lacks dynamics and low efficiency.
On the other hand, as an open and shared manufacturing service platform, cloud manufacturing has a large number of services with the same functions but different non-functional information. The existence of these services intensifies the difficulty of searching and matching service combinations

Embodiment 1

[0077] figure 1 It is a flowchart of a method for constructing a service combination candidate set provided in Embodiment 1 of the present invention.

[0078] refer to figure 1 , the method includes the following steps:

[0079] Step S110, collecting clustering index information in specific services;

[0080] Specifically, sort out the specific services registered to the cloud platform, extract the basic information description, specific input information, and specific output information of the specific service, and put the basic information description, specific input information, and specific output information into three sets respectively In , the clustering index information used as the basis for clustering.

[0081] Step S120, performing similarity calculation on the clustering index information to obtain multiple abstract services;

[0082] Specifically, the similarity calculation is performed on the clustering index information to find out the specific services whos...

[0117] Figure 6 It is a schematic diagram of a system for constructing a service combination candidate set provided in Embodiment 2 of the present invention.

[0118] refer to Figure 6 The service combination candidate set construction system includes: a clustering index information collection unit 100, an abstract service acquisition unit 200, an abstract service network construction unit 300, and a service combination candidate set acquisition unit 400;

[0119] A clustering index information collection unit 100, configured to collect clustering index information in a specific service;

[0120] An abstract service acquisition unit 200, configured to perform similarity calculation on the clustering index information to obtain multiple abstract services;

[0121] The abstract service network construction unit 300 is used to separately count the abstract in-out information in each abstract service, and calculate the similarity of the abstract in-out information to construct...

Embodiment 3

[0146] Figure 7 It is a schematic structural diagram of a system for constructing a service combination candidate set provided in Embodiment 3 of the present invention.

[0147] refer to Figure 7 , on the one hand, an abstract service network is established offline. Specifically, provider services are specific services. There are a large number of specific services on the cloud platform. The same type of specific services are aggregated to obtain abstract services, and an abstract service network is formed based on the connection relationship of abstract services. On the other hand, the service composition candidate set is constructed in the online situation. Specifically, the demander provides a specific task requirement, and according to the task requirement, searches the abstract service path in the abstract service network to obtain a service combination candidate set.

Abstract

The invention provides a service composition candidate set construction method and system, and relates to the technical field of distributed manufacturing system information integration. The method comprises the steps that clustering index information in a specific service is collected; similarity degree calculating is carried out on the clustering index information to acquire a number of abstract services; abstract access information in each abstract service is calculated, and the similarity degree of the abstract access information is calculated; an abstract service network is constructed; and searching is carried out in the abstract service network according to task requirements to acquire a service composition candidate set. According to the invention, the efficiency, the adaptability, the operability and the convenience of service composition candidate set construction can be improved.

Description

technical field [0001] The invention relates to the technical field of distributed manufacturing system information integration, in particular to a method and system for constructing a service combination candidate set. Background technique [0002] Cloud manufacturing, as a "manufacturing as a service" business paradigm, has received extensive attention since it was proposed. In the cloud manufacturing environment, distributed manufacturing resources are packaged into cloud services, and cloud platform users can put forward task requirements for the cloud platform in all stages of the production and manufacturing life cycle such as product design, manufacturing, and testing. There are many key technologies involved in cloud manufacturing, among which service composition, as an important means of service circulation, sharing and value-added, plays an important role in the cloud manufacturing platform. [0003] Service composition in the cloud manufacturing environment faces...
