Bridging Dictionary

[A] dynamic prototype from MIT’s Center for Constructive Communication that identifies how words common in American political discourse are used differently across the political divide

MIT Media Lab

Utilizing natural language processing, the Bridging Dictionary compares how two media outlets on the opposite sides of the US political spectrum–foxnews.com on the right, and msnbc.com on the left–differ in the meanings assigned to the same words or phrases. This involved gathering approximately 18,000 articles from foxnews.com and 13,000 from msnbc.com published since 2021. The content was then split into millions of sentences for analysis. The first analysis measured the differences in usage frequency and sentiment. For those terms that show significant differences, a further qualitative comparison was done using a large language model (LLM) to describe the way the usage varies between the two outlets. The LLM was then prompted to provide evidence for its conclusions by citing specific references, as well as alternative "bridging" terms.
