Penn StructLearn

These pages describe briefly Penn's StructLearn software suite. This library contains tools for both classification and sequence learning using online algorithms.

Please read the README file to learn about usage and input/output format.

Tagger

The library can also be integrated with MALLET and used as a Mallet classifier.
