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.

Latvian part-of-speech tagset is available in Latvian corpora annotated by the LV Tagger for Latvian developed by the Artificial Intelligence Laboratory of the University of Latvia, Institute of Mathematics and Computer science Machine learning code based on the Stanford NLP kit.  The used tagset is derived from MULTEXT-East morphological specification and it is very close to this tagset format.

An Example of a tag in the CQL concordance search box[tag="ncfsg4"] finds all common feminine singular nouns in genitive of 4th declension, e.g. pilsētas, mājas (note: please make sure that you use straight double quotation marks)
