COTOHA APIを使って究極の感謝を送りたい

興り

我々エンジニアは（程度の差はあれど、）臆病な生き物なので、人と話すのが苦手です。

人と話すのが嫌だからエンジニアになった、まであります。
なので専らチャットやらメールやらでやりとりするわけですが、これがまた伝わりづらい。
絵文字やスタンプなどで感情の機微を伝える方法も、、、まああるんですが、どうせなら言葉で伝えたいですよね。
感謝、ありがとうの気持ちなどは特に。

エンジニアでも感謝したい！

感謝を伝えたい、でも伝わるかわからない・・・
すごい感謝しているけどそれが伝わらなかったら・・・
どうすれば感謝が伝わるのか・・・

その悩み、技術の力で解決しましょう。

COTOHA

COTOHA® APIは、NTTグループの40年以上にわたる研究成果である日本語辞書・自然言語機能、およびCOTOHAの提供を通じて独自開発した機能をベースとした「テキスト解析」「対話」「音声認識サポート」に活用できるAPIサービスです。
Communication Engine "COTOHA® API"

公式はこちら
NTTCom社が提供している自然言語処理サービスです。

どうやって調べるか

「感情分析API」を使用します。
分析する言葉
よく言う・見る感謝のワードに副詞や助動詞、記号などをつけたり外したりして生成しました。
使用したパーツはこんな感じ

{
 prefix: ['', '超', 'マジ', '本当に', '誠に'],
 text: ['ありがとう', '感謝', '恩に着る', 'かたじけない', 'ども', 'あざす', 'ありがと', 'さんきゅ', 'サンクス', 'thx', '多謝'],
 suffix: ['', 'ね', 'です', 'ございます', 'ございました'],
 extension: ['', '。', '・・・', 'ー', '！', '〜', 'ー！', '〜！', '・・・！', '！！'],
}

リスト化すると、大体3000弱の言葉が生まれました。
これを一つ一つ感情分析します。

判断基準

使用するパラメータは**"sentiment"（感情）と"score"（センチメントスコア）**です。

「感謝」は感情的には喜んでいるはずなので、"sentiment"が"Positive"なものは感謝していると言えると思います。
また、"score"はmaxを1として、高ければ高いほど、その"sentiment"が強い、という意味です。
よって、感謝度合いとして、
「"sentiment"が"Positive"」かつ、「"score"が高い」ものがより感謝しているとします。

判定例

「ありがとう」、「ありがとう。」、「ありがとう！」を分析してみます。
それぞれこんな結果が返ってきました。

ありがとう

{
   "result": {
       "sentiment": "Neutral",
       "score": 0.3140117003315527,
       "emotional_phrase": []
   },
   "status": 0,
   "message": "OK"
}

ありがとう。

{
   "result": {
       "sentiment": "Positive",
       "score": 0.18406198502930196,
       "emotional_phrase": [
           {
               "form": "ありがとう",
               "emotion": "喜ぶ"
           }
       ]
   },
   "status": 0,
   "message": "OK"
}

ありがとう！

{
   "result": {
       "sentiment": "Positive",
       "score": 0.1823655212516051,
       "emotional_phrase": [
           {
               "form": "ありがとう",
               "emotion": "喜ぶ"
           }
       ]
   },
   "status": 0,
   "message": "OK"
}

この中だと、僅差ですが、**「ありがとう。」**が一番感謝している、と判定します。

日本語として何となく違和感を覚えますが、スコアはなんと0.65です。
「ありがとう。」が約0.2だったので、およそ3倍感謝してます。赤くなってます。というか「感謝」が総ナメです。

というわけで、エンジニアの皆さん、究極の感謝を伝えたい時は**「マジ感謝ね」**でお願いします。

以上です。

なんか、一年分くらい感謝した気がします。
