Frans Faase writes "By basing its strategies on the text of a
manual, a computer infers the meanings of words without human
supervision. The paper Learning to Win by Reading Manuals in a
Monte-Carlo Framework (PDF) explains how a computer program
succeeds in playing Civilization II using the official game
manual as a strategy guide. This manual uses a large vocabulary
of 3638 words, and is composed of 2083 sentences, each on
average 16.9 words long. By this the program improves it success
rate from 45% to 78% in playing the game. No prior knowledge of
the language is used."
