Implementation for the Bigram Anchor Words Topic Model paper. Bag of words is very poor text representation, since that, in traditional topic models, we are losing a lot of information. The project goal is to combine linguistic with statistical topic models. We propose new Anchor Words Topic Model [1] such as bigrams also could be anchor words.

Here are an example of anchor words. Metrics are also good and could be found in the paper.

You could use following code to repeat published results. A simple way to repeat experiments is to try to understand examples =) I'm sorry that documentation is absent.

cd bigram-anchor-words
ipython ./examples/{corpus}/{model}.py
