This is a part-of-speech tagset for Qtag. When you tag your corpus using tagger, you will be able to extract words of different uses. For example, do you know which form of "left" is used mot frequently: adjective use of left indicating direction, adverbial use of left indicating direction, left as the past form of leave, left as the past participle form of leave? Or if you want to find out all instances of proper nouns, you can extract all words tagged as NP1 (singular form) and NP2 (plural form). You can do this using a tagged corpus more readily than a raw corpus.
