Abstract

Semantic Web service composition is a discovery process in which a given set of requirements are fulfilled by dynamically locating and assembling semantically annotated services [5,6]. Semantic annotation of Web services is a set of models that describe its properties (e.g., inputs, outputs, process), in a formal language such as OWL-S [2]. These models provide an unambiguous description of service properties by relating them to concepts belonging to Web ontologies. While dynamic service composition provides a flexible applications which can change according to service failures and other factors, it raises several questions regarding the way users interact with the generated applications. Specifically, it raises a challenge for usability, which is defined as the effectiveness, efficiency and satisfaction in which users perform tasks using a given system [1].
