mfmt

mfmt (pronounced "em-format") is a tool for converting the output format of one morphological analyzer to another. It supports the following analyzers:

• MeCab
• Juman (Juman++)
• KyTea
• Vaporetto (bccwj-suw+unidic_pos+kana)

Install

$ pipx install mfmt

Usage

$ mfmt <command> <file>

<command> consists of the short forms of each analyzer. In mfmt, the following abbreviations are used:

• m: MeCab
• j: Juman (Juman++)
• k: KyTea
• v: Vaporetto

For example, to convert the output format from MeCab to Juman:

$ mfmt m2j mecab.txt

Conversely, to convert the format from Juman to MeCab:

$ mfmt j2m juman.txt

Please note that mfmt does not convert parts of speech. This is because it is difficult to map the part-of-speech categories between different analyzers.

Example

$ cat mecab.txt
今日	名詞,副詞可能,*,*,*,*,今日,キョウ,キョー
は	助詞,係助詞,*,*,*,*,は,ハ,ワ
よい	形容詞,自立,*,*,形容詞・アウオ段,基本形,よい,ヨイ,ヨイ
天気	名詞,一般,*,*,*,*,天気,テンキ,テンキ
です	助動詞,*,*,*,特殊・デス,基本形,です,デス,デス
。	記号,句点,*,*,*,*,。,。,。
