Androidで形態素解析する方法を以前書きました。
今回は、Windows/Pythonで形態素解析を行う方法です。
Pythonで形態素解析はMeCabを使って行えます。
Python用ライブラリのインストール
コマンドプロンプトを開き、以下を入力して" mecab-python3"をインストールします。pip install mecab-python3
続いて辞書ライブラリをインストールします。
pip install unidic
辞書ライブラリに辞書自体が含まれないので以下のようにしてインストールします。
python -m unidic download
辞書をインストールしないとMeCab実行時に以下のようなエラーが出るので注意してください。
------------------- ERROR DETAILS ------------------------ arguments: [ifs] no such file or directory: I:\python\Lib\site-packages\unidic\dicdir\mecabrc ----------------------------------------------------------
Pythonでの形態素解析の実行
MeCabとライブラリ、辞書のインストールが終わったら以下のコードで動作確認をしましょう。
import MeCab
tagger = MeCab.Tagger()
result = tagger.parse("MeCabとライブラリ、辞書のインストールが終わったら以下のコードで動作確認をしましょう。")
print(result)
以下の結果となります。
