TMSC 
TMSC (Topics Modeling on Source Code) is a command line application to discover the topics of a repository the uses provides. A "topic" is a set of keywords, in this case source code identifiers, which typically occur together. This project has nothing to do with GitHub topics.

Automatic topic inference can be useful for cataloging repositories or mining concepts from them. The current model was trained on GitHub repositories cloned in October 2016 after de-fuzzy-forking. There is a paper on it.
