Morphology

The form / lemma ratio of NUM is 1.013040 (the average of all parts of speech is 1.237686).

The 1st highest number of forms (3) was observed with the lemma “billion”: b, billion, bn.

The 2nd highest number of forms (2) was observed with the lemma “’72”: ‘72, ’72.

The 3rd highest number of forms (2) was observed with the lemma “’73”: ‘73, ’73.

NUM occurs with 4 features: NumForm (5037; 100% instances), NumType (5037; 100% instances), Abbr (84; 2% instances), Typo (2; 0% instances)

NUM occurs with 7 feature-value pairs: Abbr=Yes, NumForm=Digit, NumForm=Roman, NumForm=Word, NumType=Card, NumType=Frac, Typo=Yes

NUM occurs with 8 feature combinations. The most frequent feature combination is NumForm=Digit|NumType=Card (3774 tokens). Examples: 2, 1, 3, 5, 4, 10, 20, 6, 2005, 2003
