Owl Code Search Hard Negative Datasets
Knowledge Distillation (KD) ベースのハードネガティブ付きコード検索データセットです。
コード検索モデルShuu12121/CodeSearch-ModernBERT-Crow-v3-large-len1024-Plusを教師モデルとして、各コメントと説明コメントのペアのデータセットから各クエリに対する関数の類似度スコアを計算し、ハードネガティブ（正解に類似しているが不正解の文書）を付与しています。
概要
- 目的: コード検索モデルの Contrastive Learning / Knowledge Distillation ファインチューニング
- 言語: Go, Java, JavaScript, PHP, Python, Ruby, Rust, TypeScript（8言語）
- 総サンプル数: 4,787,740
- データサイズ: 8.73 GB（展開後） / 3.37 GB（ダウンロード時）
- フォーマット: Per-language config 形式（
scores_{lang},queries_{lang},documents_{lang}）
データ構造
各言語ごとに 3 つの config が存在します：
queries_{lang}
各クエリ（自然言語による検索文）を格納。
| カラム | 型 | 説明 |
|---|---|---|
query_id |
string |
クエリの一意識別子 |
query |
string |
自然言語のクエリテキスト（docstring / コメント） |
split |
string |
元データの分割情報 |
documents_{lang}
各文書（ソースコード）を格納。
| カラム | 型 | 説明 |
|---|---|---|
document_id |
string |
文書の一意識別子 |
document |
string |
ソースコード本文 |
split |
string |
元データの分割情報 |
scores_{lang}
教師モデルによる類似度スコアを格納。各クエリに対して、スコア順にソートされた文書 ID リストとスコアリストを保持。
| カラム | 型 | 説明 |
|---|---|---|
query_id |
string |
対応するクエリの ID |
document_ids |
list[string] |
スコア順にソートされた文書 ID のリスト |
scores |
list[float64] |
対応する類似度スコアのリスト |
split |
string |
元データの分割情報 |
スコアの解釈:
scores[0]/document_ids[0]が正例（実際のペアだったもの）score[0] = -1は正解が上位32件に検索結果が含まれていなかった場合
言語別統計
| 言語 | クエリ数 | 文書数 | スコア数 |
|---|---|---|---|
| Go | 1,361,475 | 1,361,475 | 1,361,475 |
| Java | 1,281,018 | 1,281,018 | 1,281,018 |
| JavaScript | 129,007 | 129,007 | 129,007 |
| PHP | 424,463 | 424,463 | 424,463 |
| Python | 776,900 | 776,900 | 776,900 |
| Ruby | 104,899 | 104,899 | 104,899 |
| Rust | 381,521 | 381,521 | 381,521 |
| TypeScript | 328,457 | 328,457 | 328,457 |
| 合計 | 4,787,740 | 4,787,740 | 4,787,740 |
注意点
全データをメモリに載せようとするとOOMになる可能性があります！！
使い方
基本的な読み込み
from datasets import load_dataset
# Python の scores を読み込む
scores = load_dataset(
"Shuu12121/owl_code_search_hard_negative_datasets-Pre_kd",
name="scores_python",
split="train",
)
# Python の queries を読み込む
queries = load_dataset(
"Shuu12121/owl_code_search_hard_negative_datasets-Pre_kd",
name="queries_python",
split="train",
)
# Python の documents を読み込む
documents = load_dataset(
"Shuu12121/owl_code_search_hard_negative_datasets-Pre_kd",
name="documents_python",
split="train",
)
ハードネガティブの抽出
# クエリ・文書テキストの辞書を構築
query_texts = dict(zip(queries["query_id"], queries["query"]))
doc_texts = dict(zip(documents["document_id"], documents["document"]))
# 閾値の設定
nv_threshold = 0.99 # positive スコアの 99% 未満をネガティブとする
# 1 サンプルの処理例
sample = scores[0]
query_text = query_texts[sample["query_id"]]
positive_doc = doc_texts[sample["document_ids"][0]] # scores[0] が正例
positive_score = sample["scores"][0]
hard_negatives = []
for doc_id, score in zip(sample["document_ids"][1:], sample["scores"][1:]):
if score < nv_threshold * positive_score and score != -1:
hard_negatives.append(doc_texts[doc_id])
print(f"Query: {query_text[:100]}...")
print(f"Positive: {positive_doc[:100]}...")
print(f"Hard negatives: {len(hard_negatives)}")
