Subject Re: headword field in identifiedannotations
Date Fri, 10 Jun 2016 12:08:31 GMT
I don't see any issues with adding the additional optional
attribute... I think we already did the same for other items like
relations for similar reasons.  The only catch is probably that the
dependency will need the dictionary lookup to be run first (assuming
that the logic will be added to the DP to iterate through all NE's in
the CAS) if they want to use that attribute.
