On the composability of semantic web services

Abstract

In this chapter, we propose a multilevel composability model for automatically checking the composability of semantic Web services. The model is defined by a set of rules called composability rules. Each rule specifies the constraints and requirements for checking horizontal and vertical composability. The model provides support for partial and total composability via the notions of composability degree and τ -composability. Then, we describe rules dealing with static semantic, dynamic semantic, and business process composability. Finally, we discuss future research directions in the area of service composition.
