Lemmatization doesn't work on corenlp.run

[lengockyquang]

As i know, lemmatization will return the base form with different word forms. When i used corenlp.run to pos tag, lemmtize and ner, lemmatization seem doesn't work.

I think it should return "Thank , Tom" instead of "thanks ....."

This is just a failure of the lemmatizer in general to handle the word "thanks."
