Characterizing semantic web services

Semantic Web is an extension of the current web in which data contained in the web documents are machine-understandable. On the other hand, Web Services provide a new model of the web in which sites exchange dynamic information on demand. Combination of both introduces a new concept named Semantic Web Services in which semantic information is added to the different activities involved in Web Services, such as discovering, publication, composition, etc. In this paper, we analyze several proposals implementing Semantic Web Services. In order to describe them, we create a conceptual framework characterizing the main aspects of each proposal.
