Loading location model for English NER in OpenNLP 1.5.3

I am using OpenNLP 1.5.3 and I would like to perform NER for location names in English texts. For this purpose I have downloaded the corresponding model (en-ner-location.bin) from the next url:

http://opennlp.sourceforge.net/models-1.5/

The problem is that when I try to perform NER in a text using this model with the following command:

./Opennlp/bin/opennlp TokenNameFinder en-ner-location.bin < Text.txt > Text.txt.ner_en_loc

I get the following error:

Loading Token Name Finder model ... failed
IO error while loading model file 'en-ner-location.bin'

Is there something wrong in my command or is it a bug for this model in OpenNLP 1.5.3?

Solution

  • The file was damaged. I downloaded it again and everything worked correctly.
