The ER International Conference on Conceptual Modeling is a leading international forum for presenting and discussing current research and applications in which the major emphasis is on conceptual modeling. Topics of interest span the entire spectrum of conceptual modeling including research and practice in areas such as: theories of concepts and ontologies underlying conceptual modeling; methods and tools for developing and communicating conceptual models; and techniques for transforming conceptual models into effective implementations. Also of interest are topics related to the interaction of conceptual modeling techniques with business strategy models and the effects (economical, organizational, and so forth) of good conceptual modeling techniques on the development of information systems. We encourage submissions relating to all aspects of conceptual modeling and specifically encourage research on topics of emerging interest.
