Corpus error detection / correction processing apparatus, corpus error detection / correction processing method, and program recording medium therefor

摘要

PROBLEM TO BE SOLVED: To detect various errors in a tagged corpus and to automatically correct the detected errors. SOLUTION: An error candidate segmenting part 11 segments an error candidate from the tagged corpus, an error place detecting part 12 evaluates whether the tag of the segmented error candidate is wrong by calculating the correct answer probability of the error candidate, the error probability of the error candidate and the correct answer probability of a changeable correction candidate, and an error place correcting part 13 presents the correction candidate or outputs a corrected corpus 22 on the basis of evaluation results.
