A planner for implementing semantic service agents based on Semantic Web Services initiative architecture

Abstract

The Semantic Web Services Initiative Architecture (SWSA) describes the overall process of discovering and interacting with Semantic Web services in three phases and defines a conceptual model to accomplish the specified requirements of these phases. This conceptual model is based on semantic service agents that provide and consume semantic web services and includes architectural and protocol abstractions. In this paper1, a software platform is defined which fulfills fundamental requirements of SWSA's conceptual model including all its sub-processes. Based on this software platform, requirements of the planner module are identified and such a planner has been implemented. The developed planner has the capability of executing plans consisting of special tasks for semantic service agents in a way that described in SWSA. These special tasks are predefined to accomplish the requirements of SWSA's sub-processes and they can be reused in real plans of semantic service agents both as is and as specialized according to domain requirements.
