Reactive Planning Model for Web Service Composition under Time Restrictions

This paper describes a reactive planning model which is specifically designed to handle OWL-S Semantic Web Service Composition problems. This model uses a planning technique which alternates planning and execution stages performing the composition service in order to face problems related to this task, such as the partial observability of the environment and the handling of unexpected events which had not been foreseen beforehand by the planner, providing a better reactivity and shorter total composition and the execution time of the service comparing to other proposals.
