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 present invention provides a WEB service matching method based on overlapping directed graphs, which relates to the field of computer information analysis and data processing. By loading a large number of WEB service node description files (WSDL) into the server-side memory, a large number of WEB descriptions are formed. In order to match the source data to the specified service, a vacancy seed matching model is established, and an overlapping directed graph is constructed on this basis, and the seeds are evaluated by the two key indicators of connectivity and overlapping number, and the optimal seed is found, and finally completed Matching of WEB services is a method to quickly find suitable WEB services. The present invention can be widely applied in environments where there are a large number of WEB service nodes and the search for WEB services is highly required, such as service-oriented architecture (SOA), cloud computing and other environments.

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...
