Module:Sandbox/AbstractWikipedia/GrammaticalFeatures

Module documentation

This module is part of the Abstract Wikipedia Scribunto-based NLG prototype. It specifies mapping from Wikidata grammatical features to an internal representation of features (associated with categories), and provides also an ordering of the features to be used when sorting lexeme forms in lexicographic order, in the sortForms function of the lexemes module.

local p = {}

-- Mapping of grammatical feature Q-ids in Wikidata to internal representation
-- Each internal feature is associated with a category.
-- Note that a Wikidata feature may be expanded to numerous (or in rare cases
-- zero) internal features.
-- Note that the same feature values can be used with different categories, and 
-- thus the importance of the mapping.
-- We use English names for convenience (as these are also used in the Relations
-- module), but this can be revisited.
