Our methodology follows a top-down approach [11] which is mainly composed on two steps as shown in Fig. 1: the ‘‘Knowledge Organization’’ that corresponds to conceptualizing and representing
the knowledge in an appropriate format; and the ‘‘Knowledge Acquisition and Reuse’’ that allows the users collaboratively producing and consuming the knowledge. The ‘‘Knowledge Organization’’
represents the fundamental step. First, it identifies a core ontological model named Core Reference Ontology (CRO) describing the generic concepts and relations according to the formalized requirements. Then, it specializes these concepts to reflect the domain experts’ skills and knowledge based on their collaboration, and generates the Domain Specific Ontology (DSO). The main contribution of this methodology is to avoid conflicts and human barriers
related to the personality characteristics when communicating with experts.
