Missing "pmi_ngram.py" file

[VincentDENGP]

Hi, thanks for sharing the code. I'm trying to run your code but seems missing one file "pmi_ngram.py"? Does this file be supposed to implement by myself?

Hi, I have uploaded the pmi_ngram.py. Hope it helps.
This is an example script for extracting domain-specific words/ngrams and you may find more effective strategies to extract useful ngrams.
In addition, you could tune the hyper-parameters of min_pmi, min_count, ngram_freq_threshold to build a better domain-specific vocabulary list.
Sorry for my late reply!
