About computing text detection indicators

[HHeracles]

Thanks for your work. But I have two questions I'd like to ask.

First, how do you calculate the P, R, and F of text detection? Do you need to calculate the correct text boxes through NMS first?If so, what is the threshold for calculating the NMS?
Secondly, what is Word Spotting and E2E Recognition? What is Word Spotting and E2E Recognition? What's the difference ?
Hope to get yours.Thank you very much.
