Abstract
The integration of knowledge can be considered as a guideline for managing problems that occur in the task of knowledge management, and more particularly, in the collaborative decision-making. Integration is necessary because it allows communication between different sources. Most of the proposed approaches provide limited support for all activities of the engineering process, in particular, the phase of integration. We propose a new approach to treat the integration of the corporate knowledge. This model exploits indexation techniques and natural language processing to increase productivity of knowledge engineering task during the integration of conceptual model. Our integration system offers several advantages, these include speed search due to the structure and integrity of indexing.
