Problems solved by technology

[0005] In addition, in the existing service selection process, people often do not consider the overlapping problem of discovery. For some keywords with high user query frequency, the service discovery process will be repeated many times, which not only wastes resources, but also affects discovery efficiency

Embodiment Construction

[0038] In this embodiment, the discovery method divides the process of service discovery into four levels: service selection layer, service cache layer, adaptation layer and heterogeneous discovery layer, and each level independently completes the corresponding stage of service discovery without relying on other levels task. in:

[0039]1. The main responsibility of the service selection layer is to perform service selection on the service discovery results returned by the Service Cache layer located at the lower layer. Service selection includes two steps: filtering and sorting. The filtering process is based on the user's context information, intercepting services that do not match the user's context information, and selecting services that are more relevant to the user's request; the sorting process is based on the user's preference information for the retrieved services. Perform a sorting to ensure that the services that the user is most interested in are ranked first.

Abstract

This invention relates to a service discovery method based on Service Cache, including: dividing process of service discovery into two hierarchies as service selection layer, Service Cache layer, adapting layer and an isomerism discovery layer; wherein the service selection layer is for carrying out service selection to service discovery result returned by the Service Cache layer on lower layer; the Service Cache layer only stores already received inquiry and result, and replaces the stored data when it is in short of storage space; the adapting layer consists of plural adapters for achieving adaptation from unique inquiry to isomerism delivery domain inquiry language; the isomerism delivery layer consists of isomerism delivery domains formed in specific delivery protocol, which complete interaction via upper layer from which the services inquired by the user are acquired. This invention overcomes overlapping problem of service delivery, enhances delivery efficiency of service, integrates isomerism of delivery protocol, enhances mutual operability of different delivery domains, and improves accuracy rate of service delivery as well.

Description

technical field [0001] The invention belongs to the technical field of service discovery of web services, in particular to a service discovery method based on Service Cache. Background technique [0002] Web Service (Web Service) technology is proposed to solve the problem of network application integration, so that applications can communicate with each other in a platform- and programming-language-independent manner. The Web service technology with XML / SOAP (Simple Object Access Protocol) / WSDL (Web Services Description Language) / UDDI (Uniform Description, Discovery and Integration Protocol) as the backbone endows Web services with an Its architecture eliminates the differences between systems that use different component models, operating systems, and programming languages, enabling heterogeneous systems to work together as a single computing network. With the increase of the number and types of Web services in the Internet, how to conveniently and effectively conduct ser...
