Create and Modify Named Entity Recognition Grammars

Named Entity Recognition uses grammar files to identify and tag entities in documents. They are written in XML in a format specific to Named Entity Recognition. They are then compiled, using the Named Entity Recognition command-line tool, into ECR files that Named Entity Recognition can easily read at runtime.

Named Entity Recognition includes a collection of standard grammar files that make it easy to identify common entities such as names and phone numbers. These are described in Standard Grammars.
