* TopicModelingTool is a graphical user interface (GUI) to the well-known topic modeling tool MALLET. Simon Hengchen (TIC) and Marijn Koolen added the possibility to specify a custom regular expression (RegEx) to correctly tokenize languages with accents and diacritics. The software, written in Java, now allows researchers not familiar with command line tools such as the original MALLET to easily perform (Latent Dirichlet Allocation) topic modeling! 

It can be downloaded HERE or on github (for free).
