English TreeTagger PoS tagset with Sketch Engine modifications
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.
Modified English TreeTagger part-of-speech tagset is available in English corpora annotated by the tool TreeTagger that was developed by Helmut Schmid in the TC project at the Institute for Computational Linguistics of the University of Stuttgart and containing modifications developed by Sketch Engine (currently pipeline version 2).
