Centr: Political Bias Detector
Centr is a Chrome Extension that allows you to understand the bias of articles you read. This bias is not tied to the site, but to the actual text of the article! Centr scans the article you are reading and generates a Political Bias score from a variety of statistical and deep learning methods. ? After scanning your article, Centr displays a graph visualizing the bias of the article. ? The graph provided has 5 categories along the x-axis: Left: Strong liberal bias Left Leaning: Slightly liberal bias Center: Congrats! The news source you are reading is fairly objective & unbiased. Keep reading! Right Leaning: Slight conservative bias Right: Strong conservative bias Scores represent the article only, not the overall bias of the news source itself. Centr was also trained to work best on articles related to politics, so don’t read too much into the score on the sports or tech site you may be reading. ? Ok, but how does it ACTUALLY work? The Centr model was trained on over 110,000 articles from over 15 different media sources across the political spectrum. This data was supplemented with additional articles collected via web scraping. This algorithm was used to create a language model and a classifier that sorts articles into the 5 buckets mentioned above. How do you detect bias? What actually is biased? We use the wisdom of the crowds - we source popular opinions for sites that are biased in a particular direction, like All Sides and Media Bias Fact Check. Using AI and ML to interpolate between the articles, we tease out bias from the content of the text itself! There’s no way this can be accurate, right? No, it really is... However, like most things, technology can let us down from time-to-time. Centr’s model was trained on a state of the art NVIDIA GPU, producing a score with 97% accuracy. If you think Centr is blatantly wrong, drop us a line at firstname.lastname@example.org or come visit us in our dorms @ Stanford--we’d be happy to talk ? Great, but why do we need Centr? Today’s polarized political climate and information overload makes it difficult to find objective media sources. ⚖️ Centr cuts the noise and tells you how your news leans. Knowing this might not make you happy, but it's important we all recognize our news consumption biases to have better political dialogue. Pulse created Centr as a way to show how technology can help combat fake news & media bias. ? Ok, this is dope! How do I share? We’re glad you like our product!
