Compound word segmentation device and Japanese dictionary creation device

摘要

PROBLEM TO BE SOLVED: To provide a compound word dividing device for easily dividing a compound word with high accuracy. SOLUTION: As word dividing processing, first of all, a number of characters in the KANJI stream part of inputted words is set and a frequency information array, a word division index array and a division identifier array are cleared (step S11). Next, on the basis of a dictionary having frequency information for a pair of two KANJI characters to appear in the word head and word end of a character string, the frequency information is set to a character boundary (step S12) and a basic word division index and an affix division index are set to the character boundary (step S13). Finally, the compound word is divided to the KANJI word base of two characters and the affix (prefix or suffix) of one character by the set index (step S14).
