From 683e940f7009487fd05667e623a775e734c27c9d Mon Sep 17 00:00:00 2001 From: Lman Chu Date: Thu, 16 Apr 2026 17:43:09 +0800 Subject: [PATCH 1/2] feat(i18n): add Traditional + Simplified Chinese entity detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit zh-TW and zh-CN previously had no `entity` section. Calling `detect_entities(..., languages=("zh-TW",))` silently fell back to English patterns (i18n/__init__.py:231-233), so no Chinese names were ever extracted — Chinese-speaking users got zero people or projects detected from their own notes. This adds entity sections for both locales: - `candidate_pattern`: common-surname-prefixed CJK n-grams (~100 surnames covering >95% of Taiwanese / PRC names), length capped at {1,2} trailing chars so greedy matches don't swallow the trailing verb character (e.g. 朱宜振說). - `boundary_chars`: `\u4E00-\u9FFF` so the i18n loader's script-aware wrap (introduced in #932) fires `\b` at CJK↔non-CJK transitions. This is the same mechanism used for Devanagari, applied to the CJK range. - `person_verb_patterns`: Chinese verbs attach directly to the name with no whitespace, so patterns are written as `{name}說`, `{name}問`, `{name}決定` — no `\b` or `\s+` separators. - `dialogue_patterns`: full-width colon `:`, Chinese quotes 「」『』, plus the standard Latin forms. - `pronoun_patterns`: 他 / 她 / 它 / 他們 / 她們 / 您 / 咱. - `stopwords`: ~140 common particles, pronouns, time expressions, question words, conjunctions, UI nouns, and politeness forms. **Known limitation** (explicitly covered by a test): CJK scripts have no word delimiters, so a name flanked by CJK on both sides with no punctuation or whitespace break is not extracted. This is a fundamental limit of regex-based CJK entity detection — resolving it would require a dictionary tokeniser. Realistic Chinese technical writing contains enough non-CJK neighbours (bullet lines, inline English, full-width punctuation, newlines) that 3+ occurrences normally produce matches. Verified against a realistic zh-TW PKM note: 朱宜振 extracted 11x from 8 sentences with 0.99 person-classification confidence. **Follow-ups** (separate PRs): same pattern for `ja` and `ko`, both of which currently share the silent fallback-to-English bug. Tests: 7 new tests in `tests/test_entity_detector.py`: - `test_zh_tw_candidate_extraction_at_boundaries` - `test_zh_tw_person_classification` - `test_zh_tw_stopwords_filter_common_particles` - `test_zh_tw_falls_back_to_english_for_non_cjk_names` - `test_zh_cn_candidate_extraction` - `test_zh_cn_and_zh_tw_union_covers_both_variants` - `test_zh_tw_known_limitation_inline_name_no_boundary` Full suite: 957 passed, 0 failed. --- mempalace/i18n/zh-CN.json | 88 ++++++++++++++++++++++++++++ mempalace/i18n/zh-TW.json | 88 ++++++++++++++++++++++++++++ tests/test_entity_detector.py | 107
