Problems solved by technology

The disadvantage of this organization is obvious
That is, on the one hand, due to the lack of structure of this kind of web service organization, the efficiency of web service discovery is relatively low; It is difficult to find web services that meet user needs
In addition, the needs of users are becoming more and more complex. Generally, only relying on a s

Embodiment Construction

[0029] Since the Web service ontology contains rich semantic information, the ontology concept can be used to mark the input and output parameters of the Web service ontology, and the semantic relationship of the Web service ontology concept can be used to fully mine the parameter relationship, operation relationship, and service relationship. Describe the hierarchical structure of the parameter relationship, operation relationship and service relationship in the web service ontology from two aspects of semantics and syntax, such as figure 1 shown. For each web service ontology described in a WSDL file, it can be divided into three parts: parameter layer, operation layer, and service layer, which respectively include syntax layer service relationships and semantic layer service relationships. For each operation, there are several input parameters and output parameters, so each operation can be regarded as a specific service to realize specific service functions. The service ...

Abstract

The invention discloses a service semantic relationship mining method, which comprises the following steps: mining parameter relationship; merging specific services with identical functional semantics to generate abstract services, wherein the identical functional semantics refers to identical semantics of input parameter sets and output parameter sets which form the specific service operation; mining the relationship between abstract services based on comparison between the input parameter sets and the output parameter sets; verifying whether specific service relationship exists, if yes, persisting into a database. The method can efficiently organize and manage the web services, can efficiently narrow the searching space during service discovery and service composition, brings convenience for realization of automatic service discovery and composition, and meanwhile, provides information for a service provider for maintaining vital services and developing new services by means of analytical investigation on service networks.

Description

technical field [0001] The invention relates to the organization and management technology of Web services, in particular to a method for mining semantic relations of Web services. Background technique [0002] With the continuous development and improvement of web service technology, more and more companies start to provide web service or use web service technology. Nowadays, the number of web services on the Internet is huge and widely used, such as weather query services on smartphones. [0003] The loose coupling and cross-platform characteristics of web services make it flourish on the Internet. As the number of web services increases, it becomes more and more difficult to organize web services. Under the traditional web service organization method, web services are classified according to domains and managed through directories, and only APIs with limited capabilities can be provided for users to call. The disadvantages of this organizational approach are more obviou...
