# Wapiti - A linear-chain CRF tool

    Copyright (c) 2009-2013  CNRS
    All rights reserved.

For more detailed information see the [homepage](http://wapiti.limsi.fr).

Wapiti is a very fast toolkit for segmenting and labeling sequences with
discriminative models. It is based on maxent models, maximum entropy Markov
models and linear-chain CRF and proposes various optimization and regularization
methods to improve both the computational complexity and the prediction
performance of standard models. Wapiti is ranked first on the sequence tagging
task for more than a year on MLcomp web site.

Wapiti is developed by LIMSI-CNRS and was partially funded by ANR projects
CroTaL (ANR-07-MDCO-003) and MGA (ANR-07-BLAN-0311-02).
