Ask in pairs on open text. We say, what's great about working for this organization and what would you do to improve working at this organization? You need t keep it open enough that people rite feel that they can write stuff in without having just sort of leading them in but not so open, like, is there anything else you want to tell us? Where that generally prompts people to be sarcastic and joking and not give you any serious responses. So we've got model and training data of somewhere in the region of 230 themes that people talk about in open questions. And then we analyze every single one of those themes by those categories using binary classification models.
