SYM: symbol
Definition
A symbol is a word-like entity that differs from ordinary words by form, function, or both.
Many symbols are or contain special non-alphanumeric characters, similarly to punctuation. What makes them different from punctuation is that they can be substituted by normal words. This involves all currency symbols, e.g. $ 75 is identical to seventy-five dollars.
Mathematical operators form another group of symbols.
Another group of symbols is emoticons and emoji.
Strings that consists entirely of alphanumeric characters are not
symbols but they may be proper nouns: 130XE, DC10; others
may be tagged PROPN (rather than SYM) even if they contain special
characters: DC-10. Similarly, abbreviations for single words are not
symbols but are assigned the part of speech of the full form. For
example, Sr. (senhor), kg (kilograma), km (quilômetro), Dr
(doutor) should be tagged nouns. Acronyms for proper names
such as PT and IBM should be tagged as proper nouns.
Characters used as bullets in itemized lists (•, ‣) and parentheses are not symbols, they are punctuation.
