Lenat was also careful to note that AM’s success, such as it was, was very much due to the fact that LISP’s “vocabulary” started with a strong relation to mathematics. EURISKO didn’t show anything like reasonable performance until he realized that the vocabulary it was manipulating needed to be “close” to the modeled domain, in the sense that interesting (to Lenat) statements about the domain needed to be short, and therefore easy for EURISKO to come across.
