Detection and characterization of tacit occupational knowledge through speech and behavior analysis

The industrial society facing a “skills drain” with a massive renewal of staffs these years, improving the training of newcomers in the companies has become a key point. More specifically, being able to integrate tacit knowledge as input data of occupational training programs is a significant issue. On the basis of recent work, we developed a protocol helping us, through replay interview of subjective video recordings of activities and additional experiments, to detect and characterize tacit occupational knowledge through speech and behavior analysis. The application case used to illustrate the benefit of the method is the profession of nuclear reactor pilot. Identification and characterization of a tacit knowledge was done and questions raised for further discussion and integration in the training process.
