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.


The series of European – Japanese Conference on Information Modelling and Knowledge Bases (EJC) originally started as a co-operation initiative between Japan and Finland in 1988 as a continuum to the series of Scandinavian conferences since 1982. The practical operations were then organized by professor Ohsuga in Japan and professors Hannu and Hannu Jaakkola in Finland. Geographical scope was expanded to cover first Europe and further other countries.

Working principles

The total number of participants is limited to 50 (30 papers). We want to provide time enough for the presentations and discussions. The conference is an excellent forum for networking with active research community in this important topic area. The authors must present their paper at the conference. The papers are published first by the local organizers as the conference (e-)proceedings and after the conference the improved versions of the papers in a journal print in the Series of "Frontiers in Artificial Intelligence" by IOS Press (Amsterdam). The books "Information Modelling and Knowledge Bases Vol. n" are edited by the Editing Committee of the conference.
