This thesis focuses on the transfer of scientific knowledge on recovered wood to practitioners of the wood sector. The research question is: how to transfer the scientific knowledge (collect and representation of knowledge and the transmission medium) on the recovered wood so that they may assimilate and used by non-scientific personnel of the wood sector ? Knowledge was first collected through interviews with specialists in the re-use of recovered wood and combined with acquisition of knowledge from scientific publications. The collected knowledge was then reformulated to facilitate its transfer to practitioners in the wood sector. The relevant concepts, the influences between concepts and relevant scientific results werere spectively represented via concept maps, influence graphs, and knowledge sheets. A canonical model of concept maps is proposed to enable a homogeneous representation of concepts. Transmission, assimilation and potential utilization of knowledge transfer were treated as follows : The transmission is proposed via an electronic (hypermedia) knowledge-book, the assimilation (absorption) has been taken into account through the reformulation of knowledge and a graphical representation of knowledge following a canonical concept map and sheets with a predefined format and The potential use of the transferred knowledge is facilitated by the representation of the action levers on the domain concepts in the form of influence graphs. The efficiency of knowledge transfer via the knowledge book has been evaluated according to the degree of understanding of the book content, the cognitive load of the user during use of the knowledge-book and the disorientation it caused. The experience has shown that the developed canonical form is intuitive and, like navigation in the book, does not cause disorientation or cognitive over load to the user. This promotes the assimilation and the use of the knowledge-book content. The obtained results indicate that the representation of relevant knowledge in a knowledge-book should facilitate for the transfer of scientific knowledge to professionals in the wood sector.
