A Java-based package for statistical natural language processing, document classification, clustering, topic modeling, information extraction, and other machine learning applications to text.

MALLET (MAchine Learning for LanguagE Toolkit) is a comprehensive Java-based framework designed for statistical natural language processing and machine learning applications related to text. It provides a rich set of tools for document classification, clustering, topic modeling, and information extraction. The toolkit offers efficient routines for converting text into features, supports various classification algorithms such as Naïve Bayes, Maximum Entropy, and Decision Trees, and includes evaluation metrics for assessing classifier performance. MALLET incorporates sequence tagging capabilities with algorithms like Hidden Markov Models, Maximum Entropy Markov Models, and Conditional Random Fields. Its topic modeling toolkit features implementations of Latent Dirichlet Allocation, Pachinko Allocation, and Hierarchical LDA. MALLET also includes numerical optimization methods like Limited Memory BFGS and flexible 'pipes' for text transformation, enabling tokenization, stopword removal, and conversion to count vectors. Additionally, MALLET provides support for general graphical models and CRF training through the GRMM add-on package, all under the Apache 2.0 License.
