Problems solved by technology

[0004] Since the existing WEB service discovery is based on the UDDI registry, all clients rely on a UDDI registry, which has a certain bottleneck in performance, and some large UDDI registry announced their permanent closure a few years ago. This greatly restricts the development of WEB service discovery
[0005] Moreover, with the continuous development of WEB service technology, more and more WEB services are deployed on the network. The existing UDDI-based WEB service discovery relies on users to add WEB service registration information to their registration database. The reason is that the WEB service is not registered with it. Such a WEB service cannot be the target of WEB service discovery based on UDDI; some WEB services may have been offline, but their information is still retained in UDDI, which may lead to invalid WEB services. service found
[0006] Not only that, the above-mentioned UDDI registration center is based on the keyword matching method for WEB service discovery, the matching result will be relatively rough, and WEB services with synonym, near meaning, or high semantic similarity cannot be found

Embodiment Construction

[0036] Specific embodiments of the present application will be described in detail below. It should be noted that the embodiments described here are for illustration only, and are not intended to limit the present application.

[0037] figure 2 It is the overall planning diagram of the technical solution of the present application. Such as figure 2 As shown, the processing of WEB service discovery in this application is divided into four levels, including user interface layer, core logic layer, algorithm layer and data layer.

[0038] The query request from the service requester (user) is processed at the user interface layer, and the query request is processed at the core logic layer. These processes at the core logic layer include capturing service documents, page parsing, service extraction, and service indexing As well as functions such as service search, these processing functions are based on various algorithms provided by the algorithm layer and data provided by th...

Abstract

The invention discloses a web service discovery method and device. The method includes: receiving a web service discovery request from a user; querying the user's request through a search engine on the basis of a WSDL index, and returning a queried web service list to the user. A WSDL file is established on the basis of web services on internet. The web service discovery method and device has the advantages that web services can be searched accurately and widely.

Description

technical field [0001] The present application relates to Internet technology, in particular to a method and device for discovering WEB services. Background technique [0002] WEB Service (WEB Service) is a service-oriented architecture technology that provides services through standard WEB protocols to ensure that application services on different platforms can interoperate. On the surface, WEB service is an application program, which exposes an application programming interface (API) that can be called through WEB to the outside world, and the API executes the service request submitted by the customer through the network. Such as figure 1 As shown, the WEB service provider uses WSDL (WEB service description language) language to describe the WEB service it provides, and publishes the WEB service to the UDDI (Universal Description Discovery and Integration) registration center, and then the service requester passes The UDDI (Universal Description Discovery and Integration...
