コンテンツモデレーションアノテーションの設定

アノテーターのウェルビーイングを考慮した、毒性検出、ヘイトスピーチ分類、センシティブコンテンツラベリングのためのPotato設定方法。

Potato Team

コンテンツモデレーションアノテーションには、アノテーターのウェルビーイングへの配慮、主観的なコンテンツに対する明確なガイドライン、堅牢な品質管理が必要です。このガイドでは、有害コンテンツ分類のベストプラクティスを説明します。

アノテーターのウェルビーイング

有害コンテンツへの暴露はアノテーターのメンタルヘルスに影響を与える可能性があります。保護措置を実施しましょう:

ウェルビーイング設定

yaml
surveyflow:
  on: true
  order:
    - pre_annotation
  pre_annotation:
    - "surveyflow/content_warning.jsonl"

コンテンツのぼかし

yaml
max_annotations_per_user: 100

ガイドラインのベストプラクティス

モデレーションガイドラインを作成する際:

  1. 明確な閾値の定義:何が「軽度」で何が「中度」か?
  2. 例の提供:説明付きのエッジケースを提示
  3. コンテキストへの対応:プラットフォーム/オーディエンスが判断にどう影響するか?
  4. 曖昧さの処理:意図が不明確な場合の対処法
  5. 定期的な更新:新しいコンテンツタイプに合わせてガイドラインを進化

アノテーターのサポート

  • ローテーション:同じ人に有害コンテンツを継続的に割り当てない
  • サポートへのアクセス:メンタルヘルスリソースへの簡単なアクセス
  • フィードバックチャネル:アノテーターが懸念を報告できる場
  • 認識:この作業の困難さを認識する
