extends NamedEntityRecognition

NER extended with NERF disambiguation rules.
NERF (Named Entity Recognition Framework) is an semi-supervised NER system made of generated Named Entity lists and disambiguation rules.
It is based on baseline system by:

 Nadeau, D., Turney, P. D. and Matwin, S. (2006) Unsupervised Named-Entity Recognition: Generating Gazetteers and Resolving Ambiguity.
 Proc. Canadian Conference on Artificial Intelligence.
 

NERF can handle the 200 NE types as defined in the Sekine Hierarchy:

 Sekine, S., Sudo, K. and Nobata, C. (2002) Extended Named Entity Hierarchy. 
 Proc. International Conference on Language Resources and Evaluation.
