A semantic rewriting approach to automatic information providing Web Service composition

Much work has been done on automatic information providing Web Service discovery and composition, such as the query rewriting approaches proposed by the database community and planning methods in semantic web research. This paper studies the problem of semantic information providing Web Service composition. More specifically, we propose a new method to represent the semantic information providing Web Services in the CARIN language, which seamlessly integrates both database and semantic web technologies. Then, a semantic rewriting based framework and algorithm are proposed to compose the Web Services. Through a case study we show that the new method could find more compositions compared with both query rewriting and planning based Web Service composition methods.
