A General Framework for Implicit and Explicit Debiasing of Distributional Word Vector Spaces

Anne Lauscher, Goran Glavaš, Simone Paolo Ponzetto +1

Distributional word vectors have recently been shown to encode many of the human biases, most notably gender and racial biases, and models for attenuating such biases have conseque…
