WeST and GESIS have opened a Topic Modeling portal under http://topicmodels.west.uni-koblenz.de. The portal collects and provides tools under a free license as well as tutorials for researchers from Web Science and Computational Social Science.
Currently there are materials from the Topic Model tutorial available that was given by Christoph Carl Kling, Lisa Posch, Arnim Bleier and Laura Dietz at the Web Science conference 2016 (WebSci’16). In addition it provides the „Promoss“ Topic Modelling toolbox. It was developed at WeST and GESIS and allows for an efficient implementation of Latent Dirichlet Allocation (LDA).
