Mecabの拡張辞書「mecab-ipadic-neologd」を導入する手順

こんにちは！シミダイ(@shimidai2100)です。

Mecabの辞書は古い！ということで、新語や固有名詞に強いとされている辞書「mecab-ipadic-neologd」を導入してみたいと思います。

MecabをまだLinuxにインストールしていない人は↓の記事を確認してください。

: LinuxにMeCabをインストールする手順

LinuxにMeCabをインストールする手順を紹介します。最終的には、Pythonを使用して「マルコフ連鎖」を使用して ...

mecab-ipadic-neologdをダウンロード

まずは「git」を使用して、「mecab-ipadic-neologd」をダウンロードします。

git clone https://github.com/neologd/mecab-ipadic-neologd

↓が実行ログです。

# git clone https://github.com/neologd/mecab-ipadic-neologd

mecab-ipadic-neologdの初期設定

gitでのダウンロードが完了したら、辞書データをコンパイルします。

なおコンパイル要件として、「メモリ空き容量が1.5GByte」必要とのことのなので注意してください。

cd mecab-ipadic-neologd
./bin/install-mecab-ipadic-neologd -n -a

↓が実行ログです。

# ./bin/install-mecab-ipadic-neologd -n -a

which: no patch in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/python/bin)
[install-mecab-ipadic-NEologd] :     patch is not found.

私の環境の場合、「patch」コマンドが使用出来ないと怒られました。

なので「patch」をインストールして再度実行します。
