iPhoneで使える、日本語 WordNetのObjective-Cクラスを書いてみた。

「自然言語処理は Python がいちばん」とか見てて、iPhoneで使いたかったので、Objective-Cでも書いてみようと思い、書いてみました。

日本語 WordNetデータベースにアクセスするためのObjective-Cクラス
http://nlpwww.nict.go.jp/wn-ja/

2009.4.4修正

2011.6.27
伊藤真央さんからご指摘、修正。
databaseをクローズしていない部分を修正

実用になる速度となりました。

辞書を抜いて置いてあります。
「wnjpn.db」を入れて使用してください。
