A Taxonomy of Bias-Causing Ambiguities in Machine Translation
Michal Měchura · 2022
This paper introduces a taxonomy of phenomena which cause bias in machine translation, covering gender bias (people being male and/or female), number bias (singular you versus plural you) and formality bias (informal you versus formal you).Our taxonomy is a formalism for describing situations in machine translation when the source text leaves some of these properties unspecified (eg.does not say whether doctor is male or female) but the target language requires the property to be specified (eg.because it does not have a gender-neutral word for doctor).The formalism described here is used internally by Fairslator 1 , a web-based tool for detecting and correcting bias in the output of any machine translator.
