| """用**规范 OTSL**(PaddleOCR-VL 1.6 原生约定)重建评测 pack 的 GT 列。 | |
| 为什么 | |
| ---- | |
| 现有两个 pack 都有问题: | |
| - /autodl-tmp/reshard : 数据集自带 OTSL —— 补 `<ecel>` 到固定列数, | |
| 且含 `<ulcel>`(1.6 词表里没有, 模型吐不出来) | |
| - /autodl-tmp/reshard_fixgt : 我们用 html_to_otsl 重建的 —— 不补了, 但 | |
| rowspan 被拼成 `<fcel><ulcel>...`(同行标记), | |
| 续接行没有占位, 跟 1.6 的解析语义对不上 | |
| 实测 `<ulcel>` 出现在: pubtables1m 37% / ccocr 33% / omnidocbench16 25% / | |
| pubtabnet 23% / tablet 22% / omnidocbench15 20% / ocrbenchv2 17% 的 GT 行里, | |
| 而评测器 `canonical_teds.py` 的 OTSL_KNOWN_FOREIGN 没收录它 → 被当成**正文**吞掉。 | |
| 做法: 从 pack 的 html 列按 1.6 官方语义重建(rowspan 续接是独立的 `<ucel>` 行), | |
| 写进新的 `otsl` 列, 图片等列原样搬运。定位符 `shard#rg#idx` 保持不变, | |
| 所以历史预测可以直接 join 回来重打分。 | |
| 用法: | |
| python3 src/build_norm_pack.py --src /autodl-tmp/reshard_fixgt --out /autodl-tmp/reshard_normgt | |

| # 有些 cohort 的 pack 里 html 列只是**空壳**(文字在源 OTSL 里): | |
| # synthtabnet 29990 行没有 <table> / fintabnet 9569 行 html 全是 <td></td> / | |
| # tabrecset_en 2162 行 / tabrecset_zh 全部。 | |
| # 从空壳重建会把 GT 的文字全冲掉(实测 tabrecset_en 0.8275 -> 0.3362)。 | |
| # 所以规则: **只有当 HTML 重建出的文字量不显著少于源 OTSL 时才用它**, | |
| # 否则保留源 OTSL(这些源的源 OTSL 本身没有 <ulcel>, 是干净的)。 | |
