Abstract. We present the first open and cross-disciplinary 3D Internet research platform, called ISReal, for intelligent 3D simulation of realities. Its core innovation is the comprehensively integrated application of semantic Web technologies, semantic services, intelligent agents, verification and 3D graphics for this purpose. In this paper, we focus on the interplay between its components for semantic XML3D scene query processing and semantic 3D animation service handling, as well as the semantic-based perception and action planning with coupled semantic service composition by agent-controlled avatars in a virtual world. We demonstrate the use of the implemented platform for semantic-based 3D simulations in a small virtual world example with an intelligent user avatar and discuss results of the platform performance evaluation.

This paper discusses an innovative mean on modeldriven agent-based coordination of Semantic Web services. The general idea is to define a platform independent metamodel for Semantic Web services and integrate it into a platform independent metamodel for multiagent systems. A model-driven Semantic Web services matchmaker agent in combination with model transformations between the platform independent metamodel and existing Semantic Web service formats like OWL-S allow the seamless integration of Semantic Web services into multiagent systems.
