Objective
Information modelling is becoming more and more important topic for researchers, designers, and users of information systems. The amount and complexity of information itself, the number of abstraction levels of information, and the size of databases and knowledge bases are continuously growing. Conceptual modelling is one of the sub-areas of information modelling. The aim of this conference is to bring together experts from different areas of computer science and other disciplines, who have a common interest in understanding and solving problems on information modelling and knowledge bases, as well as applying the results of research to practice. We also aim to recognize and study new areas on modelling and knowledge bases to which more attention should be paid. Therefore philosophy and logic, cognitive science, knowledge management, linguistics and management science are relevant areas, too. In the conference, there will be three categories of presentations, i.e. full papers, short papers and position papers.

Papers may be submitted in the following categories:

•Scientific/Technical Paper: You may submit your paper either as a full paper (of max. 20 pages), or as a short paper (of max. 8 pages).
•Position Paper: Research projects of any scale are invited to illustrate innovative concepts, theories, prototypes, or experiences. Your position paper (work-in-progress) should be no longer than 5 pages.
The pre-print will be distributed in the conference. The finalproceedings including the papers presented in the conference will bedistributed after the conference and published by IOS Press (Amsterdam) for international distribution.
