Abstract
The vision of the Semantic Web envisages the Web enriched with numerous domain ontologies, which specify formal semantics of data, allowing various intelligent services to perform knowledge-level information transformation, search and retrieval. Recent successful projects in the ontology area have resulted at creation of thousands ontologies, development of several ontology-based annotation tools and inference engines. However, the absence of an efficient transformation technology for distributed and evolving knowledge hampers further developments of the Semantic Web area. Preliminary non-automated knowledge transformation approaches, experimental research prototypes and early proposals of transformation languages need to evolve into a working technology with solid theoretical grounds and powerful tool support. The workshop attracted a number of high-quality submissions concerning different transformation issues and models presented in the present book. The book is opened with an extended abstract of the invited talk of F. Casati presenting a discussion about the role of services at the Semantic Web. The first section of the proceedings is devoted to model transformation approaches. The paper on ‘Effective schema conversions between XML and relational models ’ by D. Lee, M. Mani, and W. Chu is followed by the paper on ‘Transforming UML domain descriptions into configuration knowledge bases for the Semantic Web ’ by A. Felfernig, G. Friedrich, D. Jannach, M. Stumptner, and M. Zanker. Generic model transformation issues are discussed in the paper ‘On modeling conformance for
