Abstract
The vision of the Semantic Web is to make Web data machine processable, and rests on the premise that to do so we need to accommodate, somehow, the semantics of these data. Many technologies and methodologies are being developed within Artificial Intelligence, Databases, Software Engineering and Information Systems that can contribute towards the realization of this vision.
This tutorial focuses on:
| - |
Description languages for Semantic Web Services : We will investigate formal languages with well defined semantics |
| - |
Automatic Web Services discovery and selection : This involves locating Web services that provide a particular service and that adhere to requested properties. With semantic markup of services, we can specify the information necessary for Web service discovery as computer-interpretable semantic markup at the service Web sites, and a service registry search engine can automatically locate appropriate services |
| - |
Automatic Web service execution : it involves a computer program or agent automatically executing an identified Web service. Semantic markup of Web services provides a declarative, computer-interpretable API for executing services. The markup tells the agent what input is necessary, what information will be returned, and how to execute |
| - |
Automatic Web service composition and interoperation: this task involves the automatic selection, composition, and interoperation of appropriate Web services to perform some task, given a high-level description of the task's objective. Currently, if some task requires a composition of Web services that must interoperate, then the user must select the Web services, manually specify the composition, ensure that any software for interoperation is custom-created, and provide the input at choice points. With semantic markup of Web services, the information necessary to select, compose, and respond to services is encoded at the service Web sites. |
