availability of topic coherence measure

[kevinbsc]

Hi, I am running topic modeling on the data from Web of Science. Is there a method available with tethne to determine a suitable number of topics for topic modeling? I was thinking about something like topic coherence measure discussed in such papers as http://dirichlet.net/pdf/mimno11optimizing.pdf (David Mimno et al. Optimizing Semantic Coherence in Topic Models) and http://svn.aksw.org/papers/2015/WSDM_Topic_Evaluation/public.pdf

@kevinbsc Whoops, somehow missed this. Not implemented yet, but certainly possible. Coherence in Mimno et al 2012 looks pretty easy to implement. I've created TETHNE-142 for this.
