The International Workshop on Semantic Interoperability (IWSI 2011) is part of the 3rd International Conference on Agents and Artifical Intelligence (ICAART 2011). The conference was held in Rome (ITALY), a wonderful venue to exchange ideas and research on the topics of the conference. The Semantic Web would be an evolving extension of the current Web model (referred as Syntactic Web) that introduces a semantic layer in which semantics, or meaning of information are formally defined. Semantics should integrate web-centric standard information infrastructures improving several aspects of interaction among heterogeneous systems: semantic interoperability would improve common interoperability models (basic and functional interoperability) introducing the interpretation of means of data. Semantic interoperability is a concretely applicable interaction model under the assumption of adopting rich data models (commonly called Ontology) composed of concepts within a domain and the
relationships among those concepts. Semantic technologies are partially inverting the common view at actor intelligence: intelligence is not implemented (only) by actors but it is implicitly resident in the knowledge model. In other words, schemas contain information and the “code” to interpretate it. The aim of this Workshop is promoting an open international discussion among researchers from both academia and industry about Semantic Interoperability (and related issues) as well as the selection of a restricted number of high-quality selected papers about interest topics. We extend the appreciation to the authors who have prepared papers that represent the leading edge of technology, providing the foundation upon which this workshop is built. The selected papers were chosen on the basis of outstanding scientific contribution as determined by the program committee experts. The selection process began immediately after the submission deadline. Each submission was examined by at least two members of the IPC and evaluated on the criteria of scientific novelty, importance to the field and technical quality. The international technical program committee have significantly contributed to the success of this workshop. We acknowledge the support of INSTICC that makes possible the organization of this event. A special acknowledgement to Ms. Patricia Alves for the preliminary assistance as well as for the continuous help and feedback during all the steps of workshop organization. Also we would like to thank the attendees. We hope you will enjoy the workshop and your stay in Italy and be able to spend some time to visit various points of interest of Rome. We hope the workshop could contribute to the success of the conference.
