Notes:

  1. You can use any combination of the models. If you are interested in only the LOCATION names, then skip other NER models save LOCATION.

  2. NER Models for other languages are also available http://opennlp.sourceforge.net/models-1.5/ . If you choose to use different language, use those URLs in the below script.
