Venue: EMNLP 2019
Natural language processing techniques play important roles in our daily life. Despite these methods being successful in various applications, they run the risk of exploiting and reinforcing the societal biases (e.g. gender bias) that are present in the underlying data. For instance, an automatic resume filtering system may inadvertently select candidates based on their gender and race due to implicit associations between applicant names and job titles, causing the system to perpetuate unfairness potentially. In this talk, I will describe a collection of results that quantify and control implicit societal biases in a wide spectrum of vision and language tasks, including word embeddings, coreference resolution, and visual semantic role labeling. These results lead to greater control of NLP systems to be socially responsible and accountable.

Vinodkumar Prabhakaran is a computational social scientist, doing research at the intersection of AI and society. He is currently a research scientist at Google, working on issues around ethics and fairness in AI. Prior to this, he was a postdoctoral fellow in the computer science department at Stanford University, and obtained his Masters and PhD in computer science from Columbia University in 2015. His research brings together NLP techniques, machine learning algorithms, and social science methods to identify and address large scale societal issues such as gender bias, racial disparities, workplace incivility, and abusive behavior online. His work has been published in top-tier NLP conferences such as ACL, NAACL, and EMNLP, as well as multidisciplinary journals such as the Proceedings of the National Academy of Sciences (PNAS).
