Advances in Information Systems

This volume contains the proceedings of the First International Conference on Advances in Information Systems (ADVIS) held in Izmir (Turkey), 25{27 October, 2000. This conference was dedicated to the memory of Professor Esen Ozkarahan. He was great researcher who made an essential contribution to the development of information systems. This conference was organized by the Computer - gineering Department of Dokuz Eylul University of Izmir. This department was established in 1994 by the founding chairman Professor Ozkarahan and there he worked for the last ve years of his live. The main goal of the conference was to bring together researchers from all around the world working in di erent areas of information systems to share new ideas and to represent their latest results. We received 80 submissions from 30 countries. The Program Committee selected 44 papers for presentation at the conference. The invited and accepted contributions cover a large variety of topics: - neral aspects of information systems, data bases, data warehousing, computer networks, Internet technologies, content-based image retrieval, information - trieval, constraint programming and arti cial intelligence. The success of the conference was dependent upon the hard work of a large number of people. We gratefully acknowledge the members of the Program C- mittee who helped to coordinate the process of refereeing all submitted papers. We also thank all the other specialists who reviewed the papers.
