Development and Use of an Activity Model Based on Structured Knowledge: A Music Teaching Support System

To collect and explicate meaningful knowledge of a community, we propose an Activity Model based on structured knowledge. The following issues arise related to the model development: (a) difficulties in capturing activities; (b) difficulty of acquiring knowledge; and (c) difficulty in optimizing the activities to newly adopted technologies. Therefore, we are developing technologies that use on-site activities and knowledge as a knowledge-based Activity Model to enhance community intelligence (observation, judgment, cooperation). As an example of its application domain, we chose classical guitar. Classical guitar was established in the late 19th century, and systematization of classical guitar rendition has not yet been completed. Therefore, instructions for playing the guitar sometimes differ greatly among teachers, which confuses students. We thus aim at developing an instruction support system which collects the knowledge of guitar rendition while recording the student improvement process. For this study, we conducted workshops by professional guitarists and structured a knowledge model that systematizes the latest acquisition process of guitar rendition. The model will allow structuring of various activities and help improve and reconstruct music teaching services.
