TAILIEUCHUNG - Báo cáo khoa học: "SOLVING ANALOGIES ON WORDS: AN ALGORITHM"

Introduction To introduce the algorithm presented in this paper, we take a path that is inverse to the historical development of the idea of analogy (see (Hoffman 95)). This is necessary, because a certain incomprehension is faced when speaking about linguistic analogy, ., it is generally given a broader and more psychological definition. Also, with our proposal being computational, it is impossible to ignore works about analogy in computer science, which has come to mean artificial intelligence. . | SOLVING ANALOGIES ON WORDS AN ALGORITHM Yves Lepage ATR Interpreting Telecommunications Research Labs Hikaridai 2-2 Seika-tyõ Sõraku-gun Kyoto 619-0288 Japan Introduction To introduce the algorithm presented in this paper we take a path that is inverse to the historical development of the idea of analogy see Hoffman 95 .

Also with our proposal being computational it is impossible to ignore works about analogy in computer science which has come to mean artificial intelligence. 1 A Survey of Works on Analogy T1ŨS paper is not intended to be an exhaustive study. For a more comprehensive study on the subject see Hoffman 95 . Metaphors or Implicit Analogies Beginning with works in psychology and artificial intelligence Gentner 83 is a milestone study of a possible modeling of analogies such as an atom is like the solar system adequate for artificial intelligence. In these analogies two domains are mapped one onto the other thus modeling of the domain becomes necessary. sun X nucleus planet -4- electron In addition properties expressed by clauses formulae etc. are transferred from one domain onto the other and their number somehow determines the quality of the analogy. attracts sun -4- attracts nucleus planet electron moremassive sun 4 moremassive nucleus planet electron However Gentner s explicit description of sentences as an A is like a B as analogies is subject to criticism. Others . Steinhart 94 prefer to call these sentences metaphors1 the validity of which rests on sentences of the kind A is to B as c is to D for which the name analogy2 is reserved. In other W ords some metaphors are supported by analogies. For instance the metaphor an atom is like the solar system relies on the analogy an electron is to the nucleus as a planet is to the sun .3 The answer of the Al .
