MALLET is an open source toolkit for statistical natural language processing (NLP), topic modeling, clustering, and other machine learning (ML) applications over text.
Topic modeling is a ML approach to analyze large volumes of unlabeled data and automatically extract latent "topics" from the text. Such topics can be used to identify document similarity in a deeply contextual way.
In this session, we demonstrate how to use the open source tool MALLET for textual ML including topic modeling. We then go on to demonstrate how we have applied this ML technique to develop an application for fast, deep document similarity matching.
