Scientists Analyse Millions of News Articles
A study led by academics at the University of Bristol’s Intelligent Systems Laboratory and the School of Journalism at Cardiff University have used Artificial Intelligence (AI) algorithms to analyse 2.5 million articles from 498 different English-language online news outlets over ten months. The researchers found that:
Nello Cristianini, Professor of Artificial Intelligence at the University of Bristol, speaking about the research, said: “The automation of many tasks in news content analysis will not replace the human judgement needed for fine-grained, qualitative forms of analysis, but it allows researchers to focus their attention on a scale far beyond the sample sizes of traditional forms of content analysis.”
Professor Justin Lewis, Head of the School of Journalism, Media and Cultural Studies at Cardiff, said that “even some of the more predictable finding give us pause for thought. The extent to which news is male dominated shows how far we are from gender equity across most areas of public life. The fact that articles about politics are the least readable might also explain widespread public disengagement.”
