Summary

Two forms of bias that are commonly associated with natural language processing (NLP) tasks are domain bias (implicit bias towards documents from a particular domain, with lower performance over other document types) and social bias (implicit bias towards documents authored by particular types of individuals, with lower performance over documents authored by other types of individuals). In this talk, I will discuss the importance of debiasing NLP models across these dimensions, and strategies that can be employed to achieve this. I will focus the talk on the task of language identification (i.e., identifying the language(s) a written document is authored in).
