There are 7 SYM lemmas (0%), 7 SYM types (0%) and 1260 SYM tokens (0%). Out of 17 observed tags, the rank of SYM is: 15 in number of lemmas, 16 in number of types and 15 in number of tokens.

The 10 most frequent SYM lemmas: %, x, +, =, /, *, $

The 10 most frequent SYM types: %, x, +, =, /, *, $

The 10 most frequent ambiguous lemmas: x (SYM 120, NOUN 70, PUNCT 3), / (PUNCT 700, SYM 18), * (PUNCT 655, SYM 10)

The 10 most frequent ambiguous types: x (SYM 120, NOUN 41, PUNCT 3), / (PUNCT 700, SYM 18), * (PUNCT 655, SYM 10)

Morphology

The form / lemma ratio of SYM is 1.000000 (the average of all parts of speech is 2.181849).

The 1st highest number of forms (1) was observed with the lemma “$”: $.

The 2nd highest number of forms (1) was observed with the lemma “%”: %.

The 3rd highest number of forms (1) was observed with the lemma “*”: *.

SYM occurs with 1 features: ConjType (120; 10% instances)

SYM occurs with 1 feature-value pairs: ConjType=Oper

SYM occurs with 2 feature combinations. The most frequent feature combination is _ (1140 tokens). Examples: %, +, =, /, *, $
