I want to create a library to get the metrics of arXiv:1910.10872 given a model o names entity recognition, but i think it would be good if its implemented on fairlearn instead of other library.

Describe the solution you'd like

Given a model of name entity recognition, templates according to the paper or created by the user and frequency of name in a region, I want to calculate all errors described in this paper for gender bias analysis,

Describe alternatives you've considered, if relevant
