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.

Spanish FreeLing part-of-speech tagset is available in Spanish corpora annotated by the FreeLing morphological tagger based on the proposals by EAGLES, which intends to enable encode all existing morphological features for most European languages.
