# search_jev_unified_v2 数据报告(2026-09-29 更新)



对象:本目录 `train/val/test.jsonl` + `*_index.jsonl`(正式版,897,035 行)。
全部数字由全量扫描得出(扫描前已按 `manifest.json` 复核六文件 SHA-256),
机器可读版本见 [`data_report.json`](data_report.json)。

## 1. 总量

| 切分 | 行数 | 题数 | choice | score | noul |
|---|---:|---:|---:|---:|---:|
| train | 487,012 | 683,315 | 204,609 | 255,190 | 223,516 |
| val | 159,124 | 200,228 | 48,329 | 52,639 | 99,260 |
| test | 250,899 | 295,675 | 83,850 | 36,253 | 175,572 |
| 合计 | 897,035 | 1,179,218 | 336,788 | 344,082 | 498,348 |

- train 平均 1.40 题/行(qd_quality 每行 2–5 题、helpsteer2 5 维,其余多为 1–2 题)。

- 2026-09-29 屏蔽了不可判定题(见第 10 节第 5 条),题数因此比 09-28 版少 38,963 道,行数少 2,013 行。

- 输入级检查:三切分内同 (state, questions) 重复 0、同输入标签冲突 0。

- 指令多样化行:train 252,752 / val 31,996 / test 41,328(索引带 `instruction_variant`)。

## 2. 任务族

| task_family | train | val | test | 合计 | train core | train aux |

|---|---:|---:|---:|---:|---:|---:|

| `retrieval_judgment` | 153,990 | 43,446 | 18,080 | 215,516 | 66,482 | 87,508 |

| `sealed_evaluation` | – | – | 112,666 | 112,666 | – | – |

- train:core 230,227(47.3%)/ aux 256,785(52.7%)。val/test 行无 `training_lane`。
- `sealed_evaluation`(只在 test):qrecc_test_equivalence 28,222、candy_evidence 39,989、search_arena_intent 20,127、

  ragtruth 17,721、frames 5,976、agentrewardbench 631。它们是封存官方评测源,训练中无同源数据,单独报告。

- val 中 query_understanding 占 30%(atec 19,357 行),test 中 sealed_evaluation 占 45%;

  **不要直接看 val/test 总体准确率**,按族 / 来源分层汇总。

query_classification 补充行(banking77 / clinc150 / massive_zh)索引无 `language_heuristic`,上表语言按源数据集标注。

只有 train、无评估切分的来源:cfever_ev、vitaminc、chip_sts、kuake_qqr、kuake_qtr;这些能力只能在同族其他来源上评估。
afqmc、multi_cpr_* 无 test,banking77 无 val。

- train 按 `supervision`:original 205,714 / derived 161,787 / weak 88,137 / 未标(query_addon)31,374;`weak=true` 92,937 行(19.1%)。

- train 中 LLM 参与定标的行(llm_teacher + llm_vote + llm_generated + derived_llm_filtered)共 164,075 行,占 33.7%。

## 5. 难度

| difficulty | train | val | test |
|---|---:|---:|---:|
| 1 | 27,579(5.7%) | 8,546 | 17,973 |
| 2 | 248,649(51.1%) | 96,690 | 144,315 |
| 3 | 132,483(27.2%) | 48,283 | 66,248 |
| 4 | 59,577(12.2%) | 3,740 | 20,490 |
| 5 | 18,724(3.8%) | 1,865 | 1,873 |

train 各族档位占比:

| task_family | 1 | 2 | 3 | 4 | 5 |

|---|---:|---:|---:|---:|---:|

| general_understanding | 21.2% | 22.4% | 43.7% | 10.0% | 2.7% |
| evidence_judgment | – | 40.1% | 34.7% | 24.3% | 1.0% |

| retrieval_judgment | 6.2% | 41.1% | 17.6% | 24.4% | 10.7% |
| query_understanding | 6.7% | 90.9% | 2.4% | – | – |

| query_assessment | – | 38.2% | 61.8% | – | – |
| search_action | – | 50.5% | 48.3% | 1.3% | – |

| query_classification | – | 100% | – | – | – |

- 4–5 档几乎全部来自 qd_quality(4–5)、search_hardneg(hn_suff 4–5、hn_gain/hn_query_fit 3–4)与 helpsteer2/logiqa;
  val 的 4–5 档只有 5,605 行,4–5 档指标主要看 test(其中 sealed 源 ragtruth/agentrewardbench 贡献 4 档 16,934 行)。
- 59 个来源中 31 个只有单一档位(如 query_classification、intent_equivalence 全为 2 档),档内无区分度,按难度加权时注意。

## 6. 置信度(软标签)

按题统计 `confidence`(索引镜像;noul 题为 max(p, 1−p) 对应的校准值):

| 区间 | train | val | test |
|---|---:|---:|---:|
| [0.95, 1.00] | 282,690(41.4%) | 100,049 | 189,847 |
| [0.90, 0.95) | 117,044(17.1%) | 35,047 | 23,616 |
| [0.85, 0.90) | 196,745(28.8%) | 35,541 | 33,751 |
| [0.75, 0.85) | 65,140(9.5%) | 11,367 | 24,788 |
| [0.60, 0.75) | 20,795(3.0%) | 17,708 | 23,222 |
| [0.00, 0.60) | 901(0.1%) | 516 | 451 |

各族题均值(全切分):query_classification 0.970、general 0.961、query_understanding 0.940、sealed 0.941、
query_assessment 0.898、evidence 0.875、retrieval 0.867、search_action 0.849。
最低的层:weak_demonstration / weak_negative 恒为 0.70,llm_teacher 0.61–0.85(均值 0.831),

llm_vote 0.45–0.95(均值 0.870)。

## 7. 标签分布(train)

- 二分类(noul)大多接近均衡;偏斜较明显的:atec 负例 85.9%、query_info.ambiguous 负例 73.3%、duretrieval / t2retrieval

  正例 71.5%、afqmc 负例 68.6%、multi_cpr_* 负例约 66%、cfever_ev 负例 64.8%。search_hardneg 四个集为构造性 50/50。

- 多分类最高类占比:trendfact_verdict refutes 55.6%、vitaminc supports 50.2%、query_noise「有效查询」63.2%、

  query_info.missing_main「无明显缺失」49.8%、qd_quality.query_freshness never 49.9%、kuake_qic「治疗方案」35.2%;
  hn_next_hop 四个选项位置均衡(最高 25.3%)。无任何 (来源, 题目) 的最高类占比 ≥ 0.9。
- score 题(按软分 Σ档×概率):qd_quality relevance 均值 1.52、satisfaction 1.15(0–3 档,偏低)、timeliness 1.43(屏蔽无时间信息的题后)、

  authority 2.16;kuake_qqr 均值 0.63(0–2,偏低档);jd_review 中位数落在最高档(源分布偏 5 星)。



逐 (来源, 题目) 明细见 `data_report.json` 的 `train_label_balance`。

## 8. 指令多样性(train)

66 个 (来源, 题目) 中:54 个 ≥ 10 种指令,5 个 4 种(search_hardneg 四集、query_noise.noise),
3 个 3 种(query_info.info_level、query_need.need_level、query_noise.noise_type),
4 个 2 种(query_info.ambiguous / info_pair / missing_main、query_need.freshness);**单一指令 0 个**。
query_assessment 与 search_hardneg 是剩余的低多样性来源。

## 9. 输入长度

`state` 序列化(`json.dumps(ensure_ascii=False)`)字符数,全切分:

| task_family | 行数 | p50 | p95 | max | >1024 | >2048 |

|---|---:|---:|---:|---:|---:|---:|

| general_understanding | 74,361 | 65 | 1,578 | 22,140 | 7.5% | 3.6% |
| evidence_judgment | 100,518 | 375 | 2,785 | 5,917 | 18.8% | 11.1% |

| retrieval_judgment | 215,516 | 283 | 1,410 | 4,172 | 17.6% | 1.4% |
| query_understanding | 167,542 | 55 | 276 | 2,740 | 1.2% | 0.1% |

| query_assessment | 93,329 | 13 | 53 | 135 | 0 | 0 |
| search_action | 83,414 | 250 | 3,667 | 4,074 | 24.9% | 24.5% |

| query_classification | 49,689 | 33 | 80 | 435 | 0 | 0 |
| sealed_evaluation | 112,666 | 225 | 3,598 | 12,580 | 21.7% | 13.4% |



不含 questions 文本;按 token 估算时中文约 1 字 ≈ 1 token、英文约 4 字符 ≈ 1 token。



## 10. 使用时需要注意



1. **语言**:train 中中文主导 63.7%、拉丁文主导 29.7%;search_action / hn_* / evidence 的 vitaminc 系列全部是英文,

   search_action 族目前没有中文行。
2. **评估切分构成不均**:val 被 atec(19,357)、qbqtc(18,734)、vitaminc_conflict(18,628)主导;test 45% 为 sealed。

   汇总指标请按来源宏平均。

3. **弱标签层**:weak_demonstration(xyz_aquila 示范动作)与 weak_negative(改写等价的构造负例)置信度 0.70,
   qd_quality 为 LLM 教师标签——按 README「使用建议」降权。

4. **已移除的冲突样本**:同输入但标签不一致的 56 行(train 32 / val 18 / test 6)已整组移除,不在本数据中。

5. **2026-09-29 修订**(软标签不变):

   - 屏蔽不可判定题:删除该题,索引 `masked_questions` 记录原因;一行里的题全被删掉则整行移除。
     - qd_quality timeliness:无发布时间且无查询时间 23,400 道,无发布时间却标 3 档 569 道。

     - qd_quality query_freshness:同一 (query, query_time) 在不同文档下标签不一致,12,981 道。
     - qrecc:上下文为空且改写引入了新实体的正例,2,013 行,整行移除(train 281 / val 250 / test 1,482)。
   - HelpSteer2 complexity / verbosity 量表按 NVIDIA 原始定义重写。
   - 句对等价任务的 state 改为 `{query_a, query_b}`(paws_x_zh 为 `{text_a, text_b}`)。
   - vitaminc / cfever_ev 的 state 改为 `{claim, evidence}`,instructions 同步改名。

   - xyz_aquila 删去 `oxed{}` 格式尾巴。
   - 意图迁移源(query_addon)的索引 `gold` 由 answers argmax 回填。

6. **2026-09-29 修订:clue_tnews 类别映射修复**:原 label id→类名映射自 105 起错位(CLUE 官方无 105/111),

   112 旅游与 116 游戏同被映射为"股票",且缺"房产"类,约 64% 的行类别错误。已按原始数据回查 id、改用官方映射:

   改标 3,710 行(train 3,204 / val 243 / test 263),全部 5,800 行的选项扩为 15 类(补"房产"),

   概率按原置信度 0.97 重算,索引 `gold` / `original_domain_unverified` 同步;行数与其他来源不变。

7. **2026-09-29 修订:helpsteer3_chinese 偏好方向修复**:原转换把 overall_preference>0 当作 response1 更好,与 HelpSteer3 约定(及原始 best_response 字段)相反,导致全部偏好标签反向。已逐行按原始 best_response 定位更好的回复,翻转 974 行(train 945 / val 12 / test 17)的 choice / probabilities 与索引 `gold`;回复位置、置信度与行数不变。
8. **2026-09-29 修订:ragtruth / frames 字段修复**:ragtruth 原把上文截到 800 字(97% 行被截)、回复截到 1,000 字且丢了任务说明,字段还误名为 question/passage;已按原始 RAGTruth 重建为 `{query, context, response}` 全文(17,721 行逐行回查、标签一致),ragtruth 不受 4,000 字 state 上限约束(截断会让幻觉标签无从判断),因此 sealed_evaluation 的长度统计上升。frames 的 `passage` 实为维基百科 URL,改为 `{question, wiki_url, wiki_title}`(标题由 URL 解码,6 条补协议头,3 条 w.wiki 短链无标题)。题目、答案、索引与行数均不变。
