RAVINE

Note: This project ran from 2008–2010 and has now completed.

RAVINE (recombination, aggregation, and visualization of information in newsworthy expressions) was a project at Carnegie Mellon University's Language Technologies Institute. The goal of the project is to automatically produce metadata annotating freely available news articles to show statements attributed to various individuals over time, by different reporters. To do this, we will perform semantic processing on these attributions to assist in tracking multiple potentially conflicting positions over time. We are developing an interface to permit querying and browsing large collections of news stories based on this metadata, aiding humans who wish to understand not only what has been reported in the news, but also variation in news accounts around the world.
