Note that neither script requires specifying how large N should be in the N-grams. For more information about the method, see the paper at http://arxiv.org/abs/0907.1013 The two scripts are compute_ngrams.py: Compute recursive multi-word expressions from a corpus. This will write out a file of vocabulary (including multi-word expressions) and their counts. lda_topics.py: Compute multi-word expressions per-topic from a corpus and LDA-C fit. (Note: the argument --ntopics is the same as K in LDA-C.) This will write out a file for each topic with the expressions and counts. Again, see the paper for details. Any questions/comments about this code should be posted to the topic models mailing list. Subscribe at https://lists.cs.princeton.edu/mailman/listinfo/topic-models
