Information modelling is becoming increasingly important for researchers, designers, and users of information systems with artificial intelligence. The amount and complexity of information, the number of abstraction levels, and the size of databases and knowledge bases are continuously growing. Conceptual modelling is one of the sub-areas of information modelling and AI modelling. The aim of this conference is to bring together experts from different areas of computer science, AI 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 of Information modelling, knowledge bases and AI to which more attention should be paid. Philosophy and logic, cognitive science, knowledge management, linguistics and cyber-physical modelling are relevant areas, too. The conference will have three categories of presentations, i.e. full papers, short papers and position papers.

The series of European – Japanese Conferences on Information Modelling and Knowledge Bases (EJC) originally started as a cooperation 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 Kangassalo and Hannu Jaakkola in Finland. The geographical scope was expanded to cover first Europe and further other countries.
