A collaboration among interdisciplinary researchers at Concordia University and the University of Wisconsin-Madison, Project Arclight is developing a web-based tool that enables the study of 20th century American media through comparisons across time and space.
The Arclight tool uses topic modeling, named entity recognition, and ranking algorithms to analyze roughly two million pages of public domain publications digitized by the Media History Digital Library and the Chronicling America Library of Congress National Digital Newspaper Program. The results are presented as data visualizations that users may click through to access the underlying sources.
