Metro Maps of the News

Metro maps are a visual metaphor for complex, interdependent story lines developed by Dafna Shahaf. Dafna’s thesis involved techniques for automatically taking a corpus of news articles and extracting a coherent narratives that covered the overall space. For our final CS448b project, we took one of the narratives Dafna had generated and created a system for displaying the maps. (The demo is best viewed on a large monitor.)


We only had enough time to get the viewer aspect polished, but we think that it would not be too difficult to extend this framework for the construction of metro maps (in case you don’t have access to Dafna’s algorithm).

This is joint work with Russell Chou and Jacob Jensen.
