Constructor Details

#initialize(han_range: (1..Float::INFINITY), min_han_ratio: 0.0, max_tier: :rare, allow_latin: true, orthography_rejects: true, prc_topics_reject: false, punctuation: :wide, soft_lexicon_rejects: false, wenyan_min_han: 8, wenyan_min_hits: 2, wenyan_max_density: 0.05, block_tolerance: 0.0, evidence_per_100: 1.0) ⇒ Policy

Defaults impose no shape constraint. Literary-Chinese density fires only above 8 Han characters and 2 particle hits, since the ratio is unstable on shorter spans; 0.05 is the observed ceiling for modern prose quoting classical text. Block tolerance 0.0 rejects a window on one failing member; 1.0 evidence per 100 sentences is the floor below which a window carries no Taiwan-specific signal.

Class Method Details

.corpus ⇒ Policy

6..60 Han characters spans a usable sentence; 0.65 Han excludes list and table fragments while admitting embedded Latin and numerals.

Returns:



50
 
# File 'lib/twfilter/policy.rb', line 50

def corpus = new(han_range: (6..60), min_han_ratio: 0.65)

.permissive ⇒ Policy

Returns:



65
 
# File 'lib/twfilter/policy.rb', line 65

def permissive = new

.publishable ⇒ Policy

Tighter bounds for material shown to learners: 40 Han is a readable card, 0.70 suppresses code-mixed text, and the 常用 chart is the pedagogical inventory.
