Gian Piero Zarri was awarded a M.Sc. in Electronic Engineering from the University of Bologna, Italy and then a Ph.D. in Computer Science from the University of Paris-Orsay, France. He is actually Research Director at the French National Centre for Scientific Research (CNRS), where he leads a "Data Engineering" team. Dr. Zarri is known internationally for combining methods from knowledge-based systems and natural language processing, as well as databases and information retrieval systems. In the area of knowledge-based systems, inter alia, he defined and developed NKRL (short for "Narrative Knowledge Representation Language"), the knowledge representation language used in several EC-funded projects (NOMOS, COBALT, CONCERTO, EUFORBIA…). His record of research is extensive, and he is the author of more than 150 refereed papers in the fields of Artificial Intelligence (knowledge representation, expert systems, intelligent databases), Computational Linguistics, Information Retrieval, Application of Computer Science Techniques to Humanities and Social Sciences. Dr Zarri is or has been on the editorial board of some important international scientific journals and on the Programme Committee of international conferences on Knowledge-Based Systems, as the World Congress on Expert Systems, the International Symposium on Methodologies for Intelligent System, ISMIS, the International Conference on Database and Expert Systems Application, DEXA, etc. His teaching activities concern, among other things, a post-graduate course on "Knowledge Representation" at the Institut National de Langues et Civilisations Orientales (INALCO, a French Grande École) in Paris. In the past, Dr. Zarri has represented France within ECCAI (ECCAI = European Co-ordinating Committee for Artificial Intelligence), and has been an advisory trustee of the "International Association of Knowledge Engineers" (IAKE). He is currently an overseas associate of the University of London-Greenwich (UK). He has co-operated intensively with industry, and he has acted as a consultant to several European companies operating in the Artificial Intelligence domain. He has also been involved as an expert in the R&D activities of the European Union and of UNESCO.
