Identifying Semantically Similar Elements in Heterogeneous Spatial Databases Using Predicate Logic Enificant differences between the concepts that participants in the integration exercise hold for the same real world entity. A possible method for identifying semantically similar elements prior to integration is based on cognitive science theory of concept attainment. The theory identifies inclusio
