Query "Who is the current president of the United States" causes errors #2

Open zednis opened 8 years ago

zednis commented 8 years ago

Query "Who is the current president of the United States" causes exceptions to be thrown and the pipelines does not complete processing. I believe this error is caused by annotator errors that occur in process some AGU abstract candidates.

zednis commented 8 years ago

I also got a MatchFilter NullPointerException on the query "Who is the current governor of New York?"
