Frequency Timeline

Keyword mentions over time. Default aggregated by week. Select sources to compare against the People's Daily baseline.

Count shows the total number of articles containing this keyword per source. Density shows keyword frequency as a proportion — articles containing this keyword divided by total articles published by that source in the same period. This controls for differences in publication volume: a source publishing 50 keyword mentions out of 500 total articles (10%) is less saturated than one publishing 20 out of 100 (20%), even though its absolute count is higher.
