The Generalized Upper Model (GUM) (UX3)
The Generalized Upper Model is a general task and domain independent `linguistically motivated ontology' intended for organizing information for expression in natural language. The categories of the ontology enforce a consistent modelling style on any domain which is also guaranteedly appropriate for flexible expression in natural language. The Generalized Upper Model attempts to be multilingual as far as possible. (UX4)
GUM is now maintained by the Bremen Ontology Research Group. (UX5)
