以前、sudachiのユーザ辞書を作成しましたが、 今回は、同じユーザ辞書を用い、ブラウザ環境で形態素解析を行います。
参考url
- sudachipy for python (miniconda for win)による sudachiユーザ辞書作成 - end0tknr's kipple - web写経開発
- sudachipy for python による sudachiユーザ辞書の利用 (形態素解析) - end0tknr's kipple - web写経開発
- kuromoji.js + SudachiDict で形態素解析（辞書のビルド、IPADic・UniDic との比較） #JavaScript - Qiita
事前準備 1 - node.js v10.16.3 のインストール
https://github.com/coreybutler/nvm-windows/releases/download/1.1.12/nvm-setup.exe
nvm for winのインストーラが上記urlにありますので、 インストール後、以下のコマンドを実行
DOS> nvm --version 1.1.12 DOS> nvm install v10.16.3 DOS> nvm use 10.16.3 Now using node v10.16.3 (64-bit) DOS> node --version v10.16.3
事前準備 2 - kuromoji.js のインストール
DOS> npm install kuromoji ＜略＞ + kuromoji@0.1.2 DOS> cd node_modules/kuromoji DOS> npm install
上記のようにインストールすると、 以下のように辞書ファイルを作成できます。
DOS> npm run build-dict DOS> dir dict ドライブ C のボリューム ラベルがありません。 ボリューム シリアル番号は 00DD-2D3B です 2024/09/18 09:09 <DIR> . 2024/09/18 09:05 <DIR> .. 2024/09/18 09:08 55,873,342 base.dat.gz 2024/09/18 09:08 25,614,933 cc.dat.gz 2024/09/18 09:08 48,926,448 check.dat.gz 2024/09/18 09:08 12,272,244 tid.dat.gz 2024/09/18 09:09 10,529,545 tid_map.dat.gz 2024/09/18 09:09 36,804,066 tid_pos.dat.gz 2024/09/18 09:09 10,491 unk.dat.gz 2024/09/18 09:09 320 unk_char.dat.gz 2024/09/18 09:09 338 unk_compat.dat.gz 2024/09/18 09:09 1,141 unk_invoke.dat.gz 2024/09/18 09:09 1,177 unk_map.dat.gz 2024/09/18 09:09 10,524 unk_pos.dat.gz
kuromoji.js + SudachiDict 環境での ユーザ辞書作成
作成の手順は、参考urlの通りですが、 手間なので、以下のようにpython scriptにしてみました
