Abstract
To represent knowledge in a geotechnical domain, an hybrid ontology has been designed. It consists in a global ontology with concepts shared by geotechnical experts and some local ontologies representing concepts and instances of a business. Geotechnical experts cooperate thanks to the global ontologie and mappings generated between concepts of different ontologies. Following this work, we study the effects of evolution changes in the local ontologies and mappings. We propose an appropriate approach which supports these evolutions in the geotechnical domain.
