 CRF++ is a simple, customizable, and open source
 implementation of Conditional Random Fields (CRFs)
 for segmenting/labeling sequential data. CRF++ is
 designed for generic purpose and will be applied to
 a variety of NLP tasks, such as Named Entity Recognition,
 Information Extraction and Text Chunking.
