I’ve been working with Dorota Glowacka of University of Helsinki on a search system built on the ArXiv.org. We have a demo appearing in SIGIR 2016. Here is a model with 100 topics built using normalised gamma priors on topics (giving each topic a variance parameter as well as a mean parameter) on the 1.1 million abstracts to March 2016. The model took about 6 hours to run on my desktop.
