## 限制
|
||||
|
||||
1. **复核 ≈ 生产提示,且复核模型 = 对照模型。** `REVIEW_RUBRIC` 与生产 `COLLECT_INSTRUCTIONS` 逐句对应;生成 / 复核 / 对照都是 `deepseek-flash`。进入测试集的 900 条是「Flash 用近生产提示能答对目标标签」的那 900 条,被剔的 36 条恰是 Flash 不同意的。因此来源 C 上现行 97.5% / 98.8% / 94.0% 是构造出来的上界。采集层「Jev 92.2% 未过相对门槛 94.5%」**不可当作 Jev 输给现行的证据**。
|
||||
2. **采集层 intent 错例的 gold 有争议。** 来源 C 采集层 Jev intent 错例 31 条:`provide_new_evidence → answer_current_focus` 17、`unclear → answer_current_focus` 9、`stop → unclear` 4、`ask → unclear` 1。17 条 pne 几乎全是「另外 2019 年我换工作搬了家」句式,若干尾句落在当前题域,按生产提示可读成 `answer_current_focus + unsure`。9 条 unclear(「一时半会儿真捋不明白」)按「记不清 → unsure」也读得通。两类合计 ≥ 20 条,占该层 intent 错例约 2/3。gold 来自「生成目标 + Flash 复核同意」,不等于人工真值。改写示例:
|
||||
- 「另外 2019 年换过工作,感情那会儿真没细想。」gold=provide_new_evidence;可读成在回答感情采集题。
|
||||
- 「另外 2019 年搬了家,工作那摊子反而没顾上细想。」gold=provide_new_evidence;可读成在回答工作采集题。
|
||||
- 「这事我一时真说不上来。」gold=unclear;按生产提示是 unsure。
|
||||
3. **语料仍不像真人。** 修复单 1 只把长度和人设写成硬红线(已过)。原单还要求按来源 B 的标点 / 语气词比例约束,未进红线:
|
||||
|
||||
| 指标 | 来源 B(真人) | 来源 C(模拟) |
|
||||
| --- | ---: | ---: |
|
||||
| 含标点 | 13% | 98.9% |
|
||||
| 含语气词(吧/呢/啊/嗯/哦/额/emm) | 4% | 25.6% |
|
||||
| 含年份或月份 | 81% | 47.8% |
|
||||
| 带年份句里写「2019」 | — | 236 / 429 = 55% |
|
||||
| `provide_new_evidence` 里是搬家/换工作 | — | 152 / 157 |
|
||||
|
||||
根因:生成脚本 `ALT_EVENT_HINTS` 给七个领域的「另一件事」全是搬家/换工作,年份未约束,模型收敛到「另外 2019 年搬过家」。这解释了模拟语料不代表真人的一部分,也解释了采集层错例为何长得一样。本单不修,留给产品决定是否再造一轮。

任务书:`TASK-rectification-jev-intent-classifier-research-fix2-20260919.md`。**0 token**:从 `.cache/jev_intent/jev_runs_v2.json` 聚合已跑结果,未重造语料、未重跑模型。

补进报告的三组数(来源 B 157 条):

|

| 范围 | n | Jev intent | 现行 Flash intent | Jev 高置信错误 | Jev 低置信召回 | Jev 自洽 |

| 无焦点 | 33 | 78.8% | **69.7%** | **12.1%** | 20.0% | 87.9% |
|

|

无焦点层 7 条 Jev 错全是 `unclear → answer_current_focus`。现行在无焦点上更低(69.7%),10 条错里 5 条同样是 `unclear → answer_current_focus`。说明 78.8% 主要是这 33 条难,不是单 Jev 不行。
|
||||
|
||||
采集层相对门槛改为「不可判(复核与对照同源)」。限制三节已写入报告。结论仍 **缺数据**,不上线。未立 BUG。
