Problems solved by technology

[0005] To sum up, although there have been many related researches on Web services, there are few practical technologies in reality. There is still a huge gap between the actual situation of Web service applications and cutting-edge theoretical research. Promoting the development of Web service technology should become an important content of current research

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] see figure 1 , to extract the semantics of the Web service from the WSDL file, the following regeneration steps are required:

[0049] 1) Read the WSDL file that needs to be parsed, create a type set and initialize an empty ontology set to temporarily store the ontology obtained from the WSDL file, and proceed to step 2);

[0050] 2) Take out an unprocessed label from the type collection, find out whether there is an ontology with the same name as the current label to be processed in the ontology collection, if it exists, go to step 4), otherwise use the label as the name of the ontology to construct a new ontology object And add it to the ontology set, enter step 3);

[0051] 3) First analyze the grammatical structure of the label, establish the corresponding ontology and the relationship between the ontology according to the corresponding semantic ...

Abstract

Based on body learning, the invention relates to a Web service semantic extraction method, which comprises steps as follows: firstly, extracting semantic information of a current WSDL file: successively analyzing grammatical structure and type definition structure of each type by reading the type definition information of the WSDL file, and building a corresponding body structure; secondly, after completing the analysis of the current WSDL file, loading the obtained body into a database and completing a refining process to the body: successively extracting the body obtained after the analysis, searching the body library for the same or related bodies, acquiring implicit relationship between the bodies by direct comparison of the bodies, enriching the body structure, and after the completion of the process, loading the body and the comparison result into the database; and finally, building a relationship between service and the body by analysis of service-related information of the current WSDL file. The method can automatically add corresponding semantic information for service with non-semantic information by adopting the body learning method, and can be used in the service discovery field, so as to improve the efficiency of service discovery.

Description

technical field [0001] The invention relates to a method for extracting semantics of Web services, in particular to a method for extracting semantics of Web services based on ontology learning. Background technique [0002] With the maturity of Web service technology, the industry has begun to widely use Web service as a new distributed software component. However, the widespread use of Web service has also led to a sharp increase in the number of Web services available on the network. Finding, accessing, and maintaining is becoming increasingly difficult. [0003] At present, Web services are basically described by WSDL files, and UDDI (Unified Description, Discovery and Integration) technology supports the release, storage and search of Web services. This technology mainly relies on the name and description of the service for keyword search. It loses a lot of original information in the service description file, and the efficiency of users querying services is low. It can...
