In this paper, a new knowledge representation formalism, called the
entity model
, is introduced. This model can be used to address knowledge diversity by making the modeling assumptions of different knowledge representations explicit and by rooting them in a world representation. The entity model can be used to: 1) detect the possible ways in which the diversity appears in ER models and therefore improving their representational adequacy; 2) make the modeling assumptions behind different ER models explicit; 3) combine the different ER models in a unified view, thus enabling data integration.
