Abstract
In service design, it is important to use the knowledge of various areas effectively. Authors have proposed a method to acquire the design knowledge from Web which includes a large amount of information, and a method to use it for service design. It is confirmed that providing a large amount of knowledge is useful for service design, however, on the other hand, a large amount of knowledge place a burden on designers. In this paper, for the purpose of constructing a data base for service design, a method to manage service design knowledge by tagging the knowledge using service quality elements is proposed. And the effectiveness of the tag is analyzed by a comparative verification.
