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.

MULTEXT-East Morphosyntactic Croatian Specification is available in Croatian corpora. The MULTEXT-East resources are a multilingual dataset for language engineering research and development. See more at http://anthology.aclweb.org/W/W03/W03-2904.pdf

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