America's Next Topic Model

"How to choose the best topic model?" is the #1 question on our community mailing list. At RaRe Technologies I manage the community for the Python open source topic modeling package gensim. As so many people are looking for the answer, we've recently released an updated gensim 0.13.1 incorporating several new exciting features which evaluate if your model is any good, helping you to select the best topic model. Topic modeling is a technique for taking some unstructured text and automatically extracting its common themes, using machine learning. It is a great way to get a bird's eye view on a large text collection.
