Nowadays, there are a large number of Knowledge Management (KM) initiatives implemented in organizations, which often fail to manage the natural heterogeneity of organizational knowledge sources. Many approaches to KM have been only based on new information systems technologies to capture all the possible knowledge of an organization into databases that would make it easily accessible to all employees. To overcome heterogeneity, documentation overload and lack of context we propose Onto-DOM, a questionanswering ontology-based strategy within a Distributed Organizational Memory. Onto-DOM is a portable question-answering system that accepts natural language queries and, using a domain ontology, transforms and contextualizes the query eliminating the inherent natural language ambiguity. At the same time, recovers those knowledge objects with the higher probability of containing the answer.
