A tagset is a list of part-of-speech tags (POS tags for short), i.e. labels used to indicate the part of speech and sometimes also other grammatical categories (case, tense etc.) of each token in a text corpus.

Chinese NEUCSP part-of-speech tagset is available in Chinese corpora annotated by the NEUCSP tagging tool developed by the Natural Language Processing Group at Northeastern University, China.
