영문 원어  : The present invention relates to an automatic lexicon generation method, comprising the following steps of: setting a syllable of a language corresponding to learning data as an initial lexicon; performing segmentation of a syllable level corresponding to the learning data; replacing a blank of the learning data with a blank display; generating a language model from an initial segmentation result in which the blank is replaced with the blank display; combining words by using current lexicons included in the language model; and if combined words, among the combined words, are included in the current lexicons, deriving a word of which likelihood is the maximum, and adding the word to the current lexicons. The step of combining the words within a limited range of the number of the lexicons and the step of deriving a word of which likelihood is the maximum, and adding the word to the current lexicons are repeated. Therefore, it is possible to automatically generate a lexicon with a predetermined number of words, and to successfully generate a language model from the generated lexicon.
