This code contains python scripts for running the TURBOTOPICS method
on either a corpus of documents or a corpus of documents combined with
the output of LDA-C.  for both scripts, the corpus is a file of the
original text of documents, one per line.

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.
