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.

Norwegian part-of-speech tagset is available in Norwegian corpora annotated by the Oslo-Bergen Tagger.

An Example of a tag in the CQL concordance search box[tag="S[AP].*"] finds all nouns including proper nouns, e.g. Noreg, dag (note: please make sure that you use straight double quotation marks)
