Dataset Summary

本データセットは、多言語対応のコード検索タスクのために設計されたハードネガティブ付きTripletデータセットです。
各サンプルは以下で構成されます:

  • query_docstring: コードの自然言語記述
  • positive_code: 対応する正解コードスニペット
  • hard_negative_code: 類似度が高いが無関係なコードスニペット
  • similarity_score: クエリとポジティブコードのエンベディング類似度スコア

サポートするプログラミング言語は、Python、Ruby、JavaScript、Java、Rust、Go、PHPです。

データは、オープンソースリポジトリから収集され、ライセンスフィルタリング、重複排除、ノイズ除去を経て作成されました。
ハードネガティブ選定には、CodeSearch-ModernBERT-Crow-Plusモデルのエンベディング表現を用いた類似度推定が利用されています。
文字列ベースの手法(例: TF-IDF)ではなく、意味的な近さに基づいて選ばれているため、より難易度の高いネガティブサンプルが構成されています。 またTOP-5まで取得しているため幅広いネガティブサンプルを提供しています。

Supported Tasks and Leaderboards

  • コード検索 (Code Search)
  • コードクローン検出 (Code Clone Detection)
  • ハードネガティブ学習 (Hard Negative Mining)

Languages

  • Python
  • Ruby
  • JavaScript
