SudachiPy にて未知語を判定する

Posted at

Sudachi はUniDic品詞体系なので、品詞として未知語は存在しません。
SudachiPy を利用して形態素解析を行う場合、未知語を判定したい場合があります。

手元の環境は以下になります。

  • Ubuntu 22.04.2 LTS
  • Python 3.10.6
  • SudachiDict-core==20221021
  • SudachiPy==0.6.6

未知語を判定したい場合は以下のようにis_oov()を使って実装します。

from sudachipy import tokenizer
from sudachipy import dictionary

tokenizer_obj = dictionary.Dictionary().create()
mode = tokenizer.Tokenizer.SplitMode.A

contents = 'ChatGPTに質問する'

for m in tokenizer_obj.tokenize(contents, mode):
    word = m.normalized_form()
    print(word + ':未知語判定 ' + str(m.is_oov()))

上記のコードを実行すると以下のような結果になります。

chatgpt:未知語判定 True
に:未知語判定 False
質問:未知語判定 False
為る:未知語判定 False
