Confusion about lable conversion.
sbmaruf opened this issue · comments
Why do we convert NER lable from iob to iobes? While evaluating we again convert the iobes to iob to calculate the f1 score. Is there any reason for that. Does that help gaining better F1 score?
Yes, IOBES helps a bit during training, because these tags basically contain more signal than IOB. But overall this doesn't make a big difference.
Thank you for your answer.
