To enable automatic processing of human knowledge, various technologies are being studied, such as knowledge graphs. In order to enable sharing or reuse of knowledge by different applications, there must be rules or guidelines so that the same knowledge can be represented with the same knowledge graphs. However, there can be multiple ways of representing the same knowledge as knowledge graphs. This paper proposes using the entity-relationship model (ERM) for defining the concepts to be used in knowledge graphs. In this approach, individual knowledge graphs are constructed by instantiating an ERM, and knowledge graphs constructed this way can be shared or reused by different applications.
