Hofstadter, D. R. and Mitchell, M. (1995). "The Copycat project: A model of mental fluidity and analogy-making." Chapter 5 in D. R. Hofstadter, Fluid Concepts and Creative Analogies. http://web.cecs.pdx.edu/~mm/CopycatChapter.html http://web.cecs.pdx.edu/~mm/CopycatChapter.html "Copycat is a model of analogy making and human cognition based on the concept of the parallel terraced scan, developed in 1988 by Douglas Hofstadter, Melanie Mitchell, and others at the Center for Research on Concepts and Cognition, Indiana University Bloomington. Copycat produces answers to such problems as "abc is to abd as ijk is to what?" (abc:abd :: ijk:?). Hofstadter and Mitchell consider analogy making as the core of high-level cognition, or high-level perception, as Hofstadter calls it, basic to recognition and categorization. High-level perception emerges from the spreading activity of many independent processes, called codelets, running in parallel, competing or cooperating. They create and destroy temporary perceptual constructs, probabilistically trying out variations to eventually produce an answer. The codelets rely on an associative network, slipnet, built on pre-programmed concepts and their associations (a long-term memory). The changing activation levels of the concepts make a conceptual overlap with neighboring concepts." -- https://en.wikipedia.org/wiki/Copycat_(software) https://en.wikipedia.org/wiki/Copycat_(software) https://cogsci.indiana.edu/copycat.html https://cogsci.indiana.edu/copycat.html
