自然言語処理やってみた
2.
概要 ・Kaggleのデータセットを使用し、 ツイート (英語) の内容が、災害に関するもの
(1) か否 (0) か分類 2
3.
Kaggleとは 組織 (企業や政府) と、データサイエンティストや機械学習エンジニアを繋げ るプラットフォーム ・組織がCompetition形式で課題を掲載 ・データサイエンティスト、機械学習エンジニアがモデルの精度を競う ・組織が最も精度の高いモデルを買い取る(賞金) 3
4.
自然言語処理とは 自然言語 (人間が使う言葉など) を、機械で処理し内容を抽出する ・自然言語にはほとんどの場合、曖昧さがある →「〜〜〜〜
“ 東京都 “ 〜〜〜。」この文章は、 「〜〜〜〜 “ 東京 / 都 “ 〜〜〜。」or「〜〜〜〜 “ 東 / 京都 “ 〜〜〜。」 ・上記のような曖昧な表現を、機械でも正しく解釈できるようにしたい → 自然言語処理 4
5.
補足:日本語の自然言語処理の難しさ ・形態素解析が難しい → 単語の切れ目が分かりにくい(英語などはスペースがあるため、切りやすい) ・機械翻訳の場合、英語などと文構造が大きく異なる ・敬語などの存在 ・ ・ ・ 5
6.
自然言語処理のタスク ・形態素解析:文章を単語に分割し、品詞を付与する ・構文解析:文の構造を明らかにする(係り受け解析など) ・意味解析:文章の意味を決定する ・文脈解析:複数の文章の繋がりに関する解析を行う(照応解析など) 6
7.
データセットについて ・id:ツイートのID ・keyword:ツイートのキーワード(らしい)、欠損値あり ・location:ツイートされた位置、欠損値あり ・text:ツイート本文 (英語) ・target:正解ラベル(0 or
1) 7
8.
学習の流れ ① データを読み込む(訓練データ、テストデータをわける など) ② データの処理(欠損値を埋める、形態素解析 など) ③ 学習モデルを作成して、訓練データで学習 ④ テストデータを、③のモデルを使って予測 8
9.
データの処理 ー 使用するモデル・関数 ・ツイート本文を形態素解析する ・辞書
(単語にIDがマッピングされている)を基に、単語をIDに変換する 9
10.
データの処理ー実際に実行する ・単語数を最大50に設定する 10
11.
学習モデルの作成・学習 11
12.
テストデータを学習モデルで予測 ↓ ・Kaggleでは、テストデータに正解ラベルがなく、決められた形式で予測結果を 提出す る(Kaggle側で精度を出してくれる) 12
