JAPANESE TEXT CORRECTION CANDIDATE EXTRACTING DEVICE

摘要

PURPOSE:To perform the extraction of a candidate with high correction accuracy and the selection of a right answer candidate even for an error in which the erratum or the omission of a declensional KANA (Japanese syllabary) ending appears by using a conjugate character table and a conjugate word ending table. CONSTITUTION:The conjugate character table 7 storing the header of a word which becomes the verb of one KANJI(Chinese character), conjugate information in which the conjugate type and the conjugate row of the word is made into codes, a part of speech, and the precedence of the word in advance, and the conjugate word ending table 8 storing a HIRAGANA(cursive form of Japanese syllabary) which becomes the conjugate word ending of the conjugate of the verb in advance are generated. When an unknown word is generated in a HIRAGANA string just behind a KANJI string or when it is generated in the word of two KANJI characters, a correction candidate character with conjugate word ending is extracted at an extraction part 9, and furthermore, a correction candidate in which grammatical relation with a succeeding character is established is selected at a selection part 10. In such a way, it is possible to improve the correction accuracy and processing capacity, and to extract the correction candidate corresponding to the error due to omission.
