I'm the maintainer of human-learn. While I cannot speak on behalf of the maintainer of DataQA, but it does seem like this tool is more specific to the entity detection use-case. I imagine it has better support for tools that deal with text.

Human-Learn, on the other hand, is more focussed on tabular data and the scikit-learn stack. Since scikit-learn doesn't have a convenient pipeline for entity detection, I would certainly recommend exploring other tools than human-learn for this use-case.

I've not used DataQA before, but figured it'd be relevant to share my input.
