You could write a function like accuracy that takes in a "gold standard" of tagged sentences. Untag each sentence and run your tagger over it and compare it to the gold sentence. Count all the correct tags along with the total tags, then when it's finished you can calculate precision. I think you'll have to collect the stats manually.

how we can find precision ,recall and f,measure by using brill tagger,as brill's only displaying accuracy.and if we look at precision ,its formula is:

precision = Correctly tagged words by system
————————————————— x 100%
Total no. of words tagged by taggers

so from where to get tagged words, that are Correctly tagged by nltk's brill.

i've successfully run brill tagger over Urdu language,nad prb is brill takes hexadecimal code ov urdu and also showing it in hexadecimal for urdu language.bt i need to know precision ,recall and f measure to quote in my FINAL Presentation, and my MS thesis plz…
i m short with time so help me out plzzzz.

It's much more accessible than the NLTK documentation, which I now only had to use to understand some specific details. Thanks a lot!
