We propose a planning technique for the automated composition of web services described in OWL-S process models, which can deal effectively with nondeterminism, partial observability, and complex goals ...
However, in realistic cases, the planning problem is far from trivial: the planner needs to deal with the nondeterministic behaviour of web services, the partial observability of their internal status, ...

Conclusion In this paper we studied how to synthesize a composition to realize a client service request expressed as a target service a la [3, 4] , in the case where available services are only partially ...
