Natural Language Processing & Discrimination

The project analyzes how bias preexisting in text is diffused in models such as word embeddings and deep neural architectures. It also tries to develop automated methods for tracing and quantifying biases in text, such as sexism, racism and homophobia.

Mapping Disinformation Campaigns across Platforms: The German General Election

During the German general election in 2017, there were coordinated attempts to disturb online public opinion. Disinformation campaigns used different social media platforms like Facebook and Twitter. They managed to infiltrate the online reporting of major German news outlets. Due to the distributed character of disinformation campaigns, these attempts were hardly noticed by the public, and their real dimension has not yet been revealed. The project investigates manipulation patterns and their effects on electoral results. It is part of the Social Science One partnership with Facebook and organized by the Social Science Research Council. More here.


Bias by Us

By using natural language processing algorithms and data-intensive models, aims to uncover underlying stereotypes, associations, and modes of narration that media produces and reproduces when covering minority related events. The project is hosted at the center for civic media at the MIT media lab. More here.
