Social media experts testify to Congress about challenges detecting terrorist threats

Social media experts testify to Congress about challenges detecting terrorist threats. Experts at companies like Facebook testified about the lack of effectiveness AI has in detecting events like the Christchurch attacks. While the events were captured on Facebook in real-time, the social media platform explained that there wasn't enough comparable material to effectively refine an algorithm. Other factors such as internet forums expressing sympathy for the attacker's views can confuse machines. Lawmakers called for transparency for social media executives at Google, Twitter, and Facebook. Wall Street Journal
