Confusion about lable conversion.

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.
