I don't know if that sentence is a grammatical correct sentence in English. Moreover, I don't know what the meaning of the sentence.

I wonder how the other NLP tools parse that sentence. These are the results:

* Spacy [1]

  Buffalo/NNP
  buffalo/NN
  Buffalo/NNP
  buffalo/NN
  buffalo/NN
  buffalo/NN
  Buffalo/NNP
  buffalo/NN

* NLP4J [2]

  Buffalo/NNP
  buffalo/NNP
  Buffalo/NNP
  buffalo/NNP - pos2=CD
  buffalo/NNP - pos2=CD
  buffalo/NNP
  Buffalo/NNP
  buffalo/NNP

Well, that sentence really makes NLP tools confused.
