Applications of WSMO

11.4 Summary

This chapter has examined examples of applications in order to illustrate and demonstrate the benefits attainable with Semantic Web service technology. We observe that the benefits for these applications provided by new technologies are similar in many application areas. In a nutshell, the essential ingredients are as follows:

• 1. Ontologies provide formalized terminology and domain knowledge definitions, which can serve as the basis for advanced, automated information organization, management, and processing.

• 2. Web services provide a means for making computational facilities accessible and usable over the Internet via standardized interfaces.

• 3. Semantic Web services provide semantically enabled technologies for automated Web service discovery, and composition, and execution of semantic annotation of Web services.

• 4. The WSMO Framework allows Semantic Web services to be realized and and incorporates two additional top-level notions that denote core components of Web-service-based systems: Goals for semantically specifying client requests, and Mediators for handling potential mismatches that would hamper successful interaction.
