WFGY/ProblemMap/GlobalFixMap/Language

Language & Multilingual — Global Fix Map

A compact hub to stabilize cross-lingual retrieval and reasoning. Use this folder when your corpus or queries span CJK, RTL, Indic, Cyrillic, accented Latin, or when users code-switch.

Quick routes to per-page guides

• Tokenizer mismatch → tokenizer_mismatch.md
• Script mixing in one query → script_mixing.md
• Locale drift and normalization → locale_drift.md
• End-to-end overview and recipes → multilingual_guide.md

---

When to use this folder

• High similarity yet wrong meaning on bilingual or mixed-script corpora
• Citations point to the wrong section after translating the question
• Hybrid retrievers underperform a single retriever across languages
• Index “looks” healthy while coverage remains low for non-Latin scripts
• Names flip between native, transliteration, and English aliases
• zh-Hans and zh-Hant never co-retrieve, Thai recall collapses without clear reason

---

Acceptance targets

• ΔS(question, retrieved) ≤ 0.45 across language variants
• Coverage of the target section ≥ 0.70 after repair
• λ remains convergent across three paraphrases and two seeds
• E_resonance stays flat on long windows that mix scripts

Map symptoms → structural fixes (Problem Map)

Symptom	Likely cause	Open this
Wrong-meaning hits despite high similarity	Embedding not multilingual or pre-norm mismatch	embedding-vs-semantic.md
Citations jump sections after translation	Snippet schema too loose	data-contracts.md, retrieval-traceability.md
zh-Hans/zh-Hant never co-retrieve	Variant mapping missing	locale_drift.md
Thai/CJK recall collapses	Tokenizer mismatch, missing segmenter	tokenizer_mismatch.md
Mixed Latin + CJK query under-recalls	Analyzer split across scripts	script_mixing.md
Hybrid retriever worse than single	Query parsing split, mis-weighted rerank	patterns/pattern_query_parsing_split.md, rerankers.md

Fix in 60 seconds

1. Measure ΔS across variants Run question in source language, target language, and a code-switched version. If ΔS improves only after transliteration or segmentation, language handling is the failing layer.

2. Probe λ_observe Hold citations fixed and flip only script or segmentation. If λ flips, lock schema and unify analyzers.

3. Apply the smallest change

• Unify index and search analyzers, add Thai/CJK segmenters
• Map zh-Hans ↔ zh-Hant at ingest or store in variant subfields
• Add alias fields for proper nouns: native, romanized, normalized
• Normalize digits, punctuation, and diacritics for RTL/Indic consistently
• Use a multilingual embedding; otherwise add a lexical sidecar and deterministic rerank

4. Verify Coverage ≥ 0.70 and ΔS ≤ 0.45 across two languages and one mixed query. λ convergent on two seeds.

Store-agnostic quick recipes

• Elasticsearch/OpenSearch: ICU normalization, width fold, bigram analyzers for CJK, Thai segmenter, keyword subfields for product names.
• Vector stores: pre-normalize identically for corpus and queries, validate with a bilingual gold set, rerank deterministically if embeddings are monolingual.
