A focused fix when **language, script, or region metadata** is inconsistent across files, snippets, headers, analyzers, or indexes. Use this page to normalize BCP-47 tags, align analyzers and encoders, and lock the schema so retrieval stays stable.

|
||
## When to use this page
|
||
- Corpus claims `lang=en` in headers while HTML meta, PDF tags, or file paths imply non-English.
|
||
- Index analyzer set to `standard` but crawler stamped `lang=zh-Hant` or `lang=ja`.
|
||
- Mixed `lang` values inside one document after conversions or merges.
|
||
- Query comes from a UI locale while the text is in another, leading to wrong analyzer or stopword set.
|
||
- Re-ingest does not update stale `lang/script/region` fields and recall becomes unstable.
|
||
|
||
---
|
||
|
||
## Acceptance targets
|
||
- **ΔS(question, retrieved) ≤ 0.45** on three paraphrases.
|
||
- **Coverage ≥ 0.70** to the intended section.
|
||
- **λ stays convergent** across two seeds after metadata normalization.
|
||
- **E_resonance flat** on long windows after analyzer alignment.
|
||
|
||
---
|
||
|
||
## The core problem
|
||
Most stacks carry **only `lang`** and drop **`script`** and **`region`**, or they conflate **UI locale** with **content locale**. Encoders and analyzers then guess. That guess diverges from retrieval, chunking, and ranking, which raises ΔS and flips λ.
|
||
|
||
---
|
||
|
||
## 60-second fix
|
||
1) **Detect**
|
||
- Run lightweight LID on both **raw source** and **post-parser text**. Keep the probability.
|
||
- If `p_top − p_second < 0.20`, mark the snippet **mixed** and route to re-chunk.
|
||
|
||
2) **Normalize**
|
||
- Stamp **BCP-47** tags as three fields: `lang`, `script`, `region` where known.
|
||
- Normalize Unicode to **NFC** for CJK and most Latin, **NFKC** only when you must collapse width.
|
||
|
||
3) **Align analyzers and encoders**
|
||
- Choose analyzer by `(lang, script)` rather than UI locale.
|
||
- Record `analyzer_id`, `encoder_id`, `normal_form` in the snippet.
|
||
|
||
4) **Verify**
|
||
- Re-rank with a deterministic reranker.
|
||
- Recompute ΔS and λ across 3 paraphrases, two seeds. Ship if targets pass.

||
## Minimal contract you must carry
|
||
Add these keys to your snippet schema. See the full table in [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
|
||
|
||
```json
|
||
{
|
||
"snippet_id": "doc:123#p4",
|
||
"lang": "zh",
|
||
"script": "Hant",
|
||
"region": "TW",
|
||
"normal_form": "NFC",
|
||
"analyzer_id": "icu_zh_Hant",
|
||
"encoder_id": "e5-multilingual",
|
||
"lid": { "label": "zh-Hant", "p": 0.93, "method": "cld3|fasttext" },
|
||
"source_meta": { "declared_lang": "en-US", "html_meta_lang": "zh-Hant", "pdf_lang": "zh" }
|
||
}
|
||
````
|
||
|
||
**Rules**
|
||
|
||
* Prefer **content-derived** LID over HTTP headers or file paths.
|
||
* If `declared_lang` disagrees with LID, trust LID and record the disagreement.
|
||
* Never mix snippets with different `(lang, script)` into the same chunk group.
|
||
|
||

|
||
|
||
## Quick diagnosis → fix
|
||
|
||
* Answers oscillate per run although facts exist
|
||
→ The analyzer follows UI locale. Lock analyzer by snippet fields. See [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).
|
||
|
||
* High similarity yet wrong meaning
|
||
→ Encoded with a multilingual model but index analyzer used wrong token rules. Rebuild with aligned analyzer. See [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md).
|
||
|
||
* Mixed half width, punctuation, or digits break matching
|
||
→ Normalize to NFC or NFKC per policy and re-index. See [digits\_width\_punctuation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/LanguageLocale/digits_width_punctuation.md).
|
||
|
||
* Script switches mid-paragraph
|
||
→ Split at the switch and stamp each part. See [script\_mixing.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/LanguageLocale/script_mixing.md).
|
||
|
||
* CJK recall dips after parser change
|
||
→ Check wordbreak rules and ICU configs. See [cjk\_segmentation\_wordbreak.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/LanguageLocale/cjk_segmentation_wordbreak.md).

## Copy-paste prompt for your LLM step
|
||
|
||
```
|
||
I uploaded TXT OS and WFGY Problem Map.
|
||
|
||
My issue looks like mixed locale metadata:
|
||
- declared vs detected lang differ,
|
||
- analyzer_id does not match (lang, script),
|
||
- ΔS(question, retrieved) = {value}, λ = {state}
|
||
|
||
Tell me:
|
||
1) which layer is failing and why,
|
||
2) the exact WFGY page to open,
|
||
3) the minimal steps to align BCP-47, analyzer, and encoder,
|
||
4) a reproducible test that verifies ΔS ≤ 0.45 and λ convergent.
|
||
Use BBMC/BBCR/BBAM when relevant.
|
||
