Brown Corpus 1961 / POS-CQP

CQP uses brackets for token constraints. word is the surface form, lemma is the base form, and pos is the part-of-speech tag; regular expressions can combine conditions.

Examples: [pos="NN.*"] finds nouns, [lemma="develop"] finds the lemma develop, and [word="data" & pos="NN.*"] combines word and POS constraints.
