RATIONALE "Goel, Analogy & Creativity survey" A. K. Goel, "Design, Analogy, and Creativity", IEEE Intelligent Systems, vol. 12, no. 3, pp. 62-70, May-June 1997 This is a detailed and oft-cited survey: "In briefly reviewing recent research on analogy-based creative design, this article first examines characterizations of creative design and then analyzes theories of analogical design in terms of four questions: why, what, how, and when. After briefly describing recent AI theories of analogy-based creative design, the article focuses on three theories instantiated in operational computer programs: Syn, Dssua, and Ideal. From this emerges a set of research issues in analogy-based creative design. The main goal here is to sketch the core issues, themes, and directions in building such theories." [from the Abstract]
