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

こんにちは！土門大貴(daikidomon)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。

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。

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

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。
