nltk, python: collocation strength of hashtags in tweets? -


i wondering if there way adapt nltk's collocation package measure collocation strengths of 2 hashtags in collection of tweets.

suppose tweet can contain 0 or multiple hashtags , extract list of hashtags each tweet in collection. calculate, e.g., pmi of each pair of tags, based on frequency pair co-occur in same tweet.

certainly can write own program wonder if there's python package can adapted this?

for example, nltk collocation package closest know of, using collocation extract n-grams, , not know if can customise http://www.nltk.org/howto/collocations.html
