In recent years, comprehensive problem solving by artefact designers has been required as demands related to artefacts become greater and more complicated. In relation to this background, we have proposed Universal Abduction Studio (UAS), a computer environment that synthetically supports a creative design. However, in general, it is difficult for a designer to acquire multiple domain knowledge because this knowledge is accumulated manually. This paper proposes a Web-based knowledge database construction method for supporting design using UAS.
