Embodiment Construction

[0032] The present invention will be described in detail below. The service discovery tool established by the present invention can be divided into three parts:

[0033] (1) Establish an abstract index layer, match requirements through the abstract index layer, discover services in a constant order of time, and improve efficiency.

[0034] Assuming that for each service request model, it is necessary to traverse the entire service network and match all services. This method is undoubtedly too large and inefficient. The present invention solves this problem. By establishing an abstract index layer, for each service request, the time complexity is changed from O(n) to O(1), thereby greatly improving the efficiency of service discovery.

[0035] The corresponding relationship between the index layer and the specific service layer is as follows figure 2 Shown.

[0036] The establishment process of the label index layer, see image 3 . First, extract all service tags from specific servic...

Abstract

The invention belongs to the technical field of the computer service network, and relates to a method for establishment of a service discovery tool based on a service network, which comprises the following steps: extracting service tags from specific services, and removing repeated tags; for the service tags, finding a specific service comprising a corresponding service tag; establishing a corresponding relationship between each tag and a specific service; creating a tag index layer; positioning center services; for the center services, establishing expansion services between the center services and relevant services, wherein an expansion service list comprises a center service ID, a relationship type and services related to the center service; extracting service information from the service network, and working out a service discovery program based on the service network; and carrying out application program interface packaging for the service discovery program. The service discovery tool established in the invention can fully utilize the structure of the service network, and feedback the service to the user comprehensively, accurately and quickly, thereby satisfying the needs of the user.

Description

Technical field [0001] The invention relates to a semantic-based service network, in particular to a semantic-based service network service discovery tool. Background technique [0002] Web service discovery is the process of locating or discovering one or more documents describing a particular Web service. Service discovery tools can find many different types and forms of Web services provided by Web service providers, and execute Web service requests. [0003] The service discovery tool of the present invention is designed and implemented on the basis of the service network. The service network and current service discovery at home and abroad are introduced as follows. [0004] 1. Service network [0005] A service network is a network composed of services and relationships between services. It takes services as nodes and the relationships between services as edges. Among them, services can be divided into abstract services and specific services. The relationship between servic...
