DEVICE FOR AUTOMATICALLY DETECTING AND CORRECTING ERROR IN JAPANESE SENTENCE

摘要

PURPOSE:To detect the homonym error of a single word by extracting the objective case of verification shown by a verification object case determination dictionary out of a clause to modefy the objective word of verification and verifying a connecting relation in the manner of semantics between the semantic category equipped with this objective case and the objective word of verification. CONSTITUTION:The presence / absence of the connecting relation in the manner of semantics between the appearance of the verification object word and the semantic category equipped with case elements to be shown by a verification object case determination dictionary 7 out of the clause to modefy the objective word of verification is calculated while retrieving a semantic connection dictionary 8, to which these connection possibility information are described in advance, with the appearance of the verification object word and when there is no connecting relation in the manner of semantics, the objective word of verification is detected as homonym error. In respect to the detected homonym error, a word equipped with the same reading is extracted as a correction candidate and this correction candidate is replaced with the word which is verified as the homonym error. Then, verification is executed by using the semantic connection relation and the connectable correction candidate is defined as a correct candidate to the homonym error. Thus, only the correct candidate of the homonym error can be extracted.
