Matching and coordination of Semantic Web Services in distributed collaborative environment

Abstract

Following the growing of the scale of distributed collaborative work, centralized registries encounter many difficulties in integration and coordination of application services. This paper proposes a token-based approach of matching and coordination for semantic Web services in distributed collaborative environment. All service nodes are organized as an associate network. A decision algorithm of token passing through the network is introduced. The paper also makes some extension to the matching algorithm so as to not only inputs and outputs but also pre-conditions and effects are considered in the matching process.
