Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of automatic search of Web services based on semantics in the Internet environment, and provide a method for automatic search of Web services based on semantics. The algorithm finds the service related to the request from the publishing service library or from the Web, and returns the discovery result at the same time

Embodiment Construction

[0033] The invention aims to solve the problem of automatic discovery of Web services based on semantics in the Internet environment. The semantic web service IOPE comprehensive matching discovery system is shown in Figure 6-1. When it receives a user's service discovery request, the system finds the service related to the request from the publishing service library or from the Web through the corresponding matching algorithm, and returns the discovery result at the same time. The publishing service library is used to store the OWL-S description of semantic Web services or other forms of description in the system (such as the description of newly defined services in P / E matching based on ontology consistency detection). It is also possible to directly use services on the Web without publishing a service library, but the time spent by the system to find related services is greater.

[0034] The OWL DL ontology library is used to store ontologies in related fields, and users ca...

Abstract

The invention discloses a semantic-based Web service automatic searching method, which comprises the following steps of: 1) extracting the description information of Inputs, Outputs, Preconditions and Effects of a Web service; 2) matching the description information of the Inputs and the Outputs to obtain matching results; 3) matching the description information of the Preconditions and the Effects to obtain the matching results; and 4) performing comprehensive analysis on the matching results obtained by the steps 2) and 3) to obtain a final matching result. By the method, Web service discovery can be effectively realized, so that all Java-supporting Internet accessing terminals can perform automatic service discovery; and gaps in the field in China are filled, and positive impacts are certainly brought on the development of Web service technologies and Web service products.

Description

technical field [0001] The invention belongs to the technical field of Web services, and in particular relates to the design and realization of a semantic-based Web service automatic search method. Applying this method to semantic-based Web service automatic search can improve the recall and precision of service search. Background technique [0002] With the continuous development of computer technology, the computer applications of modern enterprises are becoming more and more complex, resulting in the enterprise's own information system becoming a complex situation of multi-platform and multi-system. Each platform and system uses its own protocol and port to transmit information, and cross-platform systems are relatively poor in data sharing. At the same time, these existing systems are difficult to adapt to the dynamic changes in the needs of enterprises. In order to solve these problems, scholars have begun to work on establishing standards for data format and data exc...
