YamCha is a generic, customizable, and open source text chunker oriented toward
a lot of NLP tasks, such as POS tagging, Named Entity Recognition, base NP
chunking, and Text Chunking. YamCha is using a state-of-the-art machine learning
algorithm called Support Vector Machines (SVMs), first introduced by Vapnik in
1995.

YamCha is exactly the same system which performed the best in the CoNLL2000
Shared Task, Chunking and BaseNP Chunking task.
