METHOD AND DEVICE FOR TRAINING LANGUAGE MODEL, METHOD AND DEVICE FOR KANA/KANJI CONVERSION, COMPUTER PROGRAM, AND COMPUTER READABLE RECORDING MEDIUM

摘要

PPROBLEM TO BE SOLVED: To provide a kana/kanji conversion device for converting words defined with parts of speech based on a statistical language model. PSOLUTION: In a step S7002, a computer system prepares a set (lattice) of the combination (paths) of ID where word ID and part of speech ID are mixed from inputted hiragana 704 by using a dictionary 202 and a user dictionary. In a step S7004, probability that each path occurs is extracted from a statistical language model 304, and a path/probability correlation chart 708 where each path is correlated to probability is generated. In a step S7006, the path whose probability is the highest is selected as a conversion candidate 710 from the path/probability correlation chart 708. In a step S7008, the selected path is converted into a kana/kanji character string 712 by using the dictionary 202 and a user dictionary 206. PCOPYRIGHT: (C)2004,JPO
