At Signal AI we’ve been tracking media coverage of the US Democratic Party presidential primaries – analysing media pieces from the largest set of sources in the world, in over 80 languages, crossing all sorts of media (print, online, and broadcast).
Using Artificial Intelligence, we’ve been able to track every time any candidate is referred to, even if not by name.
Between January 1 and May 31 total we’ve clocked 2,949,748 references to the major Democratic candidates, in 1,716,201 different news items. President Donald Trump, by comparison, has appeared in 8,184,437 pieces in the same period.
Over half (57.7%) of this coverage has been on four of the candidates: Sen. Bernie Sanders, Joe Biden, Sen. Elizabeth Warren, and Sen. Kamala Harris.

Our index uses Artificial Intelligence so that we can track candidates as trained ‘entities’.
Traditionally, tracking has relied on imprecise keyword searches or clunky Boolean strings. This has issues. For example, searching for ‘John Delaney’ as a key word would surface content not only about Rep. John Delaney, but also John Delaney, the Chief Executive Officer of the Football Association of Ireland. Previous analysis, by other organisations, has relied on “a name appearing in a story” to count as a mention. This leads to inaccurate and incomplete research.
An ‘entity’ can be any organisation, individual, location, or event. In this case we have trained our AI to recognise any time the Democratic candidates are mentioned. It understands context, synonyms, antonyms, and can disambiguate similar or identical keywords. This allows us to capture a much more complete picture of the candidates. For example, our AI registers if Sen. Bernie Sanders has been referred to, regardless of how he is referred to – be it “Sanders, Sen. Sanders, ‘Crazy Bernie’, United States Senator from Vermont, etc.”

Using entities allows us to build the most complete image of a candidate’s coverage in the world.
