Analysis and Modeling of Common Concept Structure of Manufacturing Skilled Workers by Action Decomposition Tree Method: Ceramic skilled workers as a case study

Abstract

We extracted the conceptual structure of skilled workers' manufacturing using ceramic artisans as a case study, and modeled the common conceptual structure using the action decomposition tree method, one of the methods of ontology engineering. In addition, we conducted an Internet survey to analyze the extent to which survey respondents who are engaged in manufacturing themselves have acquired and recognized common conceptual structures, with the aim of explicating the concepts of skilled workers and the process by which they are acquired. As a result, 19 common conceptual structures were extracted by the action decomposition tree method, and the model was made explicit. The survey results also suggested that the concepts needed or used differ depending on the type of manufacturing and years of experience, as well as the order in which the upper ranked concepts of manufacturing and the lower ranked concepts to achieve them are acquired and recognized.
