Aggregation method to reuse knowledge from project memory

The knowledge engineering offers a rational framework allowing a representation of knowledge obtained through the experiences. This technique found a great application in knowledge management and especially to capitalize knowledge.In fact, the rational representation of knowledge allows their exploitation and their re-use.It is a necessary condition to allow are-use and a knowledge appropriation.The knowledge management must take into account this dimension, since its first concern is to make knowledge persistent, ready to be re-used.In this paper, we study the traces classifications of the design project achievements in order to have a knowledge aggregation and to thus provide a representation of handled knowledge, directives and competences organization as well as negotiation strategies and cooperative problems solving.
