Description: CRFSuiteTagger
        ==============
        
        _CRFSuiteTagger_ is a sequence tagger based on the [pycrfsuite](https://github.com/tpeng/python-crfsuite "pycrfsuite") python wrapper for [CRFSuite](http://www.chokkan.org/software/crfsuite/ "CRFSuite"). It is built for chunking, NER, and other BIO (also referred to as IOB) based text annotation tasks.
        
        ### Why would you need this?
        
        _CRFSuiteTagger_ has a wide selection of common features, and the capability to easily integrate additional ones. The features are controlled using a simple string-based feature template. Additional features can be easily added through new _feature generating functions_ (see `crfsuitetagger.ftex`) passed on the `CRFSuiteTagger` constructor.
        
        ### Installation
        
        You should be able to install _CRFSuiteTagger_ as any other Python package:
        
            python setup.py install
        
        ### Dependencies
        
        You will need the following Python packages and one of my other libraries:
        
        * [pycrfsuite](https://github.com/tpeng/python-crfsuite  "pycrfsuite") - python wrapper for CRFSuite
        * [numpy](http://www.numpy.org/ "NumPy") - you should it
        * [bioeval](https://github.com/savkov/bioeval "bioeval") - my library for evaluating BIO style annotation, which replaces the perl script from [CoNLL-2000](http://ilk.uvt.nl/team/sabine/chunklink/chunklink_2-2-2000_for_conll.pl)
        
        ### TODO
        
        * command line interface
        * migrate data structure to [pandas](http://pandas.pydata.org/ "pandas")
        * more examples
