Problems solved by technology

It solves the problem that the composition of Web services in the prior art is limited by actual application scenarios and the quality of composition is low
Solve the problem that the method for avoiding the occurrence of loops in the prior art can only be applied to a single input parameter and a single output parameter

example

[0135] Example: A user wants to get the weather conditions on the day of a repertoire, and the service request WSR=((play, date_time), weather_condition, show), takes the repertoire play and performance time date_time as input, and the weather condition weaher_condition as output, this WSR belongs to the show field. Here, the minimum threshold of semantic similarity is 0.85. All the Web services used in this instance are shown in Table 1.

Abstract

The present invention provides a semantic Web service automatic combination method based on a body. The method comprises the steps of obtaining a Web request service; searching all Web services (WS) of which the exit semantics match the exit semantic of the Web request service from a Web service list; using a from-right-to-left matching combination algorithm, searching all WS' of which the exit semantics match the entrance semantics of the WS from the Web service list, and combining the WS and the WS' into the new WS until all entrance semantics of the Web request service match the WS. The semantic Web service automatic combination method based on the body of the present invention solves the problems in the prior art that the Web service combination is limited by the actual application scenes, and the combination quality is low.

Description

technical field [0001] The invention relates to Web service composition technology, in particular to an ontology-based Web service composition method, specifically an ontology-based semantic Web service automatic composition method. Background technique [0002] Web services can overcome the heterogeneous problems in the system development process, and can avoid repeated development of repeated functions, and improve development efficiency and quality. However, the functions of Web services are usually relatively simple and cannot meet the needs of all users. Through Web service composition technology, multiple Web services with single functions can be combined to achieve stronger functions. At the same time, due to the large number of Web services, manual composition is time-consuming and labor-intensive and has poor flexibility. Therefore, it is necessary to study the automatic composition technology of Web services. [0003] Web service automatic composition technology i...
