Notes:
STTS/HW lacks generic tags for punctuation and other: They could be supplemented as $ (for punctuation) and X (for other)
UP-12 lacks a tag for interjection; interjections are mapped to the class X (c.f. https://code.google.com/p/universal-pos-tags/source/browse/trunk/nl-alpino.map)
UP-12 and UD-17 lack a tag for article, it is absorbed into the determiner class.
UP-12 and UD-17 have a class determiner mostly separated out of the pronoun class; this separation is completely unnatural to German speakers, compare the translation from STTS to UD-17
The use of DET is inconsistent in UD-17; e.g., Latin seems to have no determiners at all (c.f. Tagset la::conll).
TANL lacks the category particle, the Italian negation particle non is classified as an adverb.
TANL considers article, determiner, predeterminer, and pronoun as first-class citizens in parts-of-speech.
TANL has one-letter class names: elegant, but not necessarily mnemonic.
