The MEKA project provides an open source implementation of methods for multi-label classification and evaluation. It is based on the WEKA Machine Learning Toolkit. Several benchmark methods are also included, as well as the pruned sets and classifier chains methods, other methods from the scientific literature, and a wrapper to the MULAN framework.
*NEW* May 27, 2014 Meka is now on Maven Central. To include it in your projects,
Download MEKA here.
Or checkout the code with subversion:
svn checkout svn://svn.code.sf.net/p/meka/code/trunk meka-code
Or get a nightly snapshot.
