The CBC newsworld holodeck

Abstract

For the past 73 years, the CBC has disseminated a unique Canadian perspective across the world, producing a phenomenally rich multimedia record of the country and our social, political and cultural heritage and news. This project utilizes visualization and sonification of portions of an enormous historical CBC Newsworld data corpus to enable an "on this day" experience for viewers. The digitized collection of 24-hour news videos spans a 24-year period (1989-2013) within an immersive multiscreen environment, to enable gesture-driven context-aware browsing, information seeking, and segment review. Employing natural language processing technologies, the interface displays keywords and key phrases identified in the transcripts, enabling serendipitous video search and display and offering a unique browsing opportunity within this rich "big data" corpus.
