Google steps up efforts to block extremism, following Facebook

Google is stepping up its efforts to block "extremist and terrorism-related videos" over its platforms, using a combination of technology and human monitors. The measures announced on Sunday come on the heels of similar efforts unveiled by Facebook last week, and follow a call by the Group of Seven leaders last month for the online giants to do more to curb online extremist content. "While we and others have worked for years to identify and remove content that violates our policies, the uncomfortable truth is that we, as an industry, must acknowledge that more needs to be done," said a blog post by Google general counsel Kent Walker. Walker said Google would devote more resources to apply artificial intelligence to suppress YouTube videos used in support of extremist actions. "This can be challenging: a video of a terrorist attack may be informative news reporting if broadcast by the BBC, or glorification of violence if uploaded in a different context by a different user," he said. "We will now devote more engineering resources to apply our most advanced machine learning research to train new 'content classifiers' to help us more quickly identify and remove extremist and terrorism-related content." Google acknowledged that technology alone cannot solve the problem, and said that it would "greatly increase the number of independent experts" on the watch for videos that violate its guidelines. "Machines can help identify problematic videos, but human experts still play a role in nuanced decisions about the line between violent propaganda and religious or newsworthy speech," Walker said. Google plans to add 50 non-government organisations to the 63 it already works with to filter inappropriate content.
