The 2nd highest number of forms (2) was observed with the lemma “billion”: billion, bn.
The 3rd highest number of forms (1) was observed with the lemma “1”: 1.
NUM occurs with 3 features: NumForm (464; 100% instances), NumType (464; 100% instances), Abbr (4; 1% instances)
NUM occurs with 6 feature-value pairs: Abbr=Yes, NumForm=Digit, NumForm=Roman, NumForm=Word, NumType=Card, NumType=Frac
NUM occurs with 5 feature combinations.
The most frequent feature combination is NumForm=Digit|NumType=Card (288 tokens).
