Problems solved by technology

[0020] WEB service technology is widely used in distributed computing, WebService, SOA and other modern information technologies. In an environment where there are a large number of WEB services, how to quickly find matching WEB services based on keywords is an important means for the development of modern WEB frameworks. The traditional keyword search method is inefficient and cannot adapt to the situation of massive WEB information query

Embodiment Construction

[0068] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0069] The present invention will be described in detail according to the five steps of WSDL description file loading, establishment of slot seeds, generation of overlapping directed graphs, calculation of connectivity and overlapping numbers, and matching based on optimal slot seeds:

[0070] Step 1: The server side loads a large number of WSDL description files from the WEB server in the network to form a large amount of source data of the WSDL description file on the server side. This step is a prior art.

[0071] The specific method of step 1 is: use the hypertext transfer protocol to connect all the remote WSDL file addresses required, and analyze the WEB service description file through the document object tree model. include all The nodes are loaded into the server-side me...

Abstract

The invention provides a WEB service matching method based on an overlapped oriented graph and relates to the field of computer information analysis and data processing. Description files (WSDL) of a large amount of WEB service nodes are loaded into a server side internal memory to form massive amounts of WEB description source data, a vacancy seed matching model for matching of specified service is built, the overlapped oriented graph is constructed on the basis, seeds are evaluated through two key indexes including connectivity and overlapping number to find optimal seeds, the WEB service matching is finished finally, and the WEB service matching method is quick in finding and appropriate. The WEB service matching method can be widely applied to an environment with a large amount of WEB service nodes and high WEB service finding requirement, such as a service oriented architecture (SOA) and a cloud computing environment.

Description

technical field [0001] The invention belongs to the field of computer information analysis and data processing, and in particular relates to a WEB service matching method based on an overlapping directed graph. Background technique [0002] Web service (WebService) is a service based on XML and HTTP, and each web service corresponds to a WSDL (WebServicesDescriptionLanguage) description file. WSDL description file is an XML language file used to describe Web services and explain how clients communicate with Web services. [0003] Each WSDL description file encapsulates several callable interfaces and their description documents, but when there are a large number of WSDL description files, how to quickly find the required service interface is a problem that needs to be solved. [0004] 1. WEB service description [0005] Service-Oriented Architecture (Service-Oriented Architecture, SOA) brings a new integration idea, according to which a flexible service-centric architectur...
