Hi, Sumit.
This is not a "bug" so much as a quirk of the machine-learned model used by the POS. Currently, POS and Chunker make predictions in a pipelined fashion -- the Chunker uses POS tags as features when determining the label of a given chunk, but it also considers lexical features -- in this case, the evidence from the non-POS features appears to be strong enough to outweigh the incorrect signal from POS.
Regards,
Mark

Hi,
I am using Illinois POS tagger and Illinois Chunker. For the following sentence the chunk output is fine but the POS coming is bit surprizing."I have an ipod mini and it is a great buy but I'm probably the only person that dislikes the itune software."
Chuck for dislikes is VP but POS for dislikes is NN
Can you please look into this.
Thanks & Regards
