Hi,
Thanks for the confirmation. IM50re.txt is a plain text corpus. Let us say
that we want to count the words in this corpus. In the NLTK book, there is an
example.
>>> import nltk
>>> nltk.corpus.gutenberg.fileids()
['austen-emma.txt', 'austen-persuasion.txt', 'austen-sense.txt',
'bible-kjv.txt',
'blake-poems.txt', 'bryant-stories.txt', 'burgess-busterbrown.txt',
'carroll-alice.txt', 'chesterton-ball.txt', 'chesterton-brown.txt',
'chesterton-thursday.txt', 'edgeworth-parents.txt', 'melville-moby_dick.txt',
'milton-paradise.txt', 'shakespeare-caesar.txt', 'shakespeare-hamlet.txt',
'shakespeare-macbeth.txt', 'whitman-leaves.txt']
These are the texts that come with NLTK.
>>> emma = nltk.corpus.gutenberg.words('austen-emma.txt')
>>> len(emma)
192427
So this is the number of words in a particular 'austen-emma.txt'. How would I
do this
with my IM50re.txt? It seems the code "nltk.corpus.gutenberg.words" is specific
to some Gutenberg corpus installed with NLTK.
Like this many examples are given for different analyses that can be done with
NLTK. However they all seem to be specific
to one of the texts above or another one already installed with NLTK. I am not
sure how to apply these examples to my own corpus.
Thank you. You are my own source of help right now; I have been trying
to figure this out all day now.

That seems to be working then. You should be able to get a list of words with
wordlists.words('IM50re.txt')

I have no idea. Is IM50re.txt a plain text corpus? What is a package?
What is a lemmatizer?
I don't know anything about NLTK, I'm just good at reading manuals.
You have to give me more help than that. What have you tried? Can you
find an example that is similar to what you want to do? Don't assume I
know what you are talking about :-)
Kent
