Co-Prot é g é : Collaborative Ontology Building with Divergences

In this paper we present an innovative approach to develop a domain ontology in collaborative fashion. This approach is synthesized in a groupware application which is called Co-Protégé, a set of plug-ins which extends Protégé. This approach is innovative because Co-Protégé enables the coexistence of divergent conceptualizations and the discussion thread in order to record the ontology evolution.
