Numbers, Numeral Classifiers and more
Kanji Numbers
These are parsed using the normal grammar, as described in Bender (2002).
Hindu-Arabic numbers
What we should do is parse numbers and pass them through using SMAF.
ChaSen settings
We set ChaSen to join numbers together:
(連結品詞 ((名詞 数))
((記号 アルファベット)))
(COMPOSIT_POS ((名詞 数))
((記号 アルファベット)))
Work Around
Until we have a proper preprocessor, we just add all numbers from 0--999, using the script utils/make-num.perl. We add fullwidth and halfwidth (marked -a for ascii) versions. We could add more as needed.
n_card-42 := card_2_no_valence & [ STEM < "４２" >, SYNSEM.LKEYS.KEYREL.CARG "42" ]. n_card-42-a := card_2_no_valence & [ STEM < "42" >, SYNSEM.LKEYS.KEYREL.CARG "42" ].
