An ISAL Approach for Design Rationale Discovery Using Patent Documents

摘要

The management of design rationale (DR) is an important task in design study. However, existing DR approaches are unable to discover DR from the large amount of archived design documents. It motivates us to propose a new DR representation model, ISAL (issue, solution and artifact layer), using patent documents. In this chapter, we first reviewed existing DR approaches. Then, we proposed an ISAL for DR discovery. Finally, we have conceptually evaluated ISAL and IBIS (Issue-based information system) using sample patents of inkjet printer. The results demonstrate the merits of ISAL model proposed.
