nltk - Frequency Distribution Comparison Python -

-

i'm using python , nltk study texts , want compare frequency distributions of parts of speech across different texts.

i can 1 text:

from nltk import *  x_tagged = pos_tag(word_tokenize(open('/users/x.txt').read()))  x_fd = freqdist([tag word, tag in x_tagged]) x_fd.plot(cumulative=true, title='part of speech distribution in corpus x')

i've tried add without luck. i've conditional frequency distribution example comparing count of 3 words across several texts, instead i'd lines represent 4 different texts, y-axis represent counts , x-axis represent different parts of speech. how compare texts y , z in same graph?

the freqdist.plot() method convenience method.

you need write plotting logic (using matplotlib) include multiple frequency distributions in 1 plot.

the source code of plotting function of freqdist might god point started. matplotlib has tutorial , beginners guide.
