Tacit Skills Discovery by Data Mining
The aim is to extract only experts’ “skills” without “individual habits” by extracting data of postures and actions of expert Japanese drum players and then conducting data mining of the collected data. In order to discover the skills of the experts, we obtain data of postures and actions of novices to compare them with the data of the experts to extract skills. As a stage before automated skill extraction, in the present study, we examined whether it is possible to extract skills from limited data. We found that recording the positions of joints, grip strengths, and the accelerations of the drumstick allowed extraction of Japanese drum playing skills. By comparing the experts’ movements with the novices’ ones, we also found skills common to the experts. Further, we could create a model of automated skill extraction from experts’ movements and body dimensions.
