I am trying to use Stanford NER tagger from the following link:NER tagger I output format I have chosen 'slashTags' and entered the following sentence:
While in France, Christine Lagarde discussed short-term stimulus efforts in a recent interview with the Wall Street Journal.
Here is what I got back:
While/O in/O France/LOCATION,/O Christine/PERSON Lagarde/PERSON discussed/O short-term/O stimulus/O efforts/O in/O a/O recent/O interview/O with/O the/O Wall/O Street/O Journal/O./O
Location, person and organization tags make sense, but what does
O tag mean?
