Different Approaches to Build Brief Ontologies

This paper introduces the problem of building brief ontologies in order to use only a relevant portion of an ontology. It describes the procedure of generation that preserves partially the original taxonomy. Therefore, concepts definitions, ranges and properties domains are processed in order to be generalized. The paper also presents a methodology consisting of seven steps to build a brief ontology. This method is applied to an ontology for environmental assessment in order to build a specific brief ontology for floods.
