NUM: numeral

Definition

A numeral is a word, functioning most typically as a determiner, adjective or pronoun, that expresses a number and a relation to the number, such as quantity, sequence, frequency or fraction.

Cardinal numerals are covered by NUM whether they are used as determiners or not (as in Windows Seven) and whether they are expressed as words (four), or digits (4).

There are numerals belonging to other parts of speech in the universal tagging scheme, based mainly on syntactic criteria: e.g. ordinal numerals are tagged as adjectives or pronouns (first, second, third, …). In Italian there are no adverbial numerals like [cs] poprvé “for the first time” nor multiplicative numerals such as [en] (once, twice).

Note that, since Roman numerals (IV) are only used as ordinal numerals in Italian (Enciclopedia Treccani), are tagged ADJ for coherence with other ordinal numerals. In this case we specify NumType=Ord as morphological feature. A similar treatment is reserved to a cardinal with a suffix such as a, o, esimo, esima, or the symbol ° (similar to the English use of the suffix “th”).

Other words functioning as determiners (including quantifiers such as many and few) are tagged DET.

Treebank Statistics (UD_Italian)

There are 1117 NUM lemmas (6%), 1128 NUM types (4%) and 5041 NUM tokens (2%). Out of 17 observed tags, the rank of NUM is: 5 in number of lemmas, 5 in number of types and 12 in number of tokens.

The 10 most frequent NUM lemmas: due, 1, 2, tre, 3, cinque, 4, mila, quattro, 5

The 10 most frequent NUM types: due, 1, 2, tre, 3, cinque, 4, mila, quattro, 5

The 10 most frequent ambiguous types: 1 (NUM 178, PROPN 1), 4 (NUM 69, PROPN 1), 5 (NUM 58, PROPN 1), sei (NUM 35, VERB 5, AUX 4), 7 (NUM 34, PROPN 1), 1994 (NUM 31, NOUN 1), dieci (NUM 26, PROPN 2), venti (NUM 20, NOUN 4), un (DET 2359, NUM 16, PRON 1), 22 (NUM 16, PROPN 1)

Morphology

The form / lemma ratio of NUM is 1.009848 (the average of all parts of speech is 1.488836).

The 1st highest number of forms (3) was observed with the lemma “cinquanta”: cinquant’, cinquanta, cinquant’.

The 2nd highest number of forms (3) was observed with the lemma “uno”: un, una, uno.

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

NUM occurs with 1 features: it-feat/NumType (5041; 100% instances)

NUM occurs with 3 feature-value pairs: NumType=Card, NumType=Gen, NumType=Range

NUM occurs with 3 feature combinations. The most frequent feature combination is NumType=Card (5016 tokens). Examples: due, 1, 2, tre, 3, cinque, 4, mila, quattro, 5
