Using term frequency to identify trends in the media's coverage of health.
This poster describes a method of analyzing news reports to detect emerging trends in the media's coverage of health. The method examines term frequency and term usage in overall and health-specific news coverage. Term frequency calculation and analysis algorithms have been implemented in SalientNews, a news aggregation and analysis system. By using term frequency, SalientNews is now able to assist in the identification and analysis of emerging trends in the media's coverage of health.
