Google to increase number of staff detecting extremist content on YouTube

Google to increase number of staff detecting extremist content on YouTube

The announcement comes after British Prime Minister Theresa May put heavy pressure on the social media companies to remove radical content after a series of deadly terror-related attacks this year in the United Kingdom.

According to Wojcicki, YouTube spent past year "testing new systems to combat emerging and evolving threats" and invested in "powerful new machine learning technology", and is now ready to employ this expertise to tackle "problematic content".

The reports led several big brands including Mars and Adidas to pull advertising from the site.

Earlier this year, advertisers fled the site after ads appeared next to extremist content. Some 98 percent of videos that were removed were initially flagged by the "machine-learning algorithms".

Wojcicki wants to find a new approach to advertising on the platform.

In order to combat this issue, the video hosting intends to "apply stricter criteria and conduct more manual curation" while simultaneously boosting its team of human reviewers "to ensure ads are only running where they should".

Going forward, she said that YouTube would be "carefully considering which channels and videos are eligible for advertising".

Nawaz, Maryam leave for London
Sharif's sons have failed to appear in the court despite repeated summons which prompted the court to separate their case. Former prime minister and president of PML-N, Nawaz Sharif departed for London on Tuesday from Lahore airport.

"This will also help vetted creators see more stability around their revenue".

U.S. IT giant Google will increase the number of employees engaged in the detection of extremist content on its video-sharing service YouTube, as well as other materials violating the service's rules, YouTube CEO Susan Wojcicki said.

Wojcicki said machine learning is helping Youtube's human reviewers remove almost five times as many videos than previously and that today, 98 per cent of the videos removed for violent extremism were flagged by machine-learning algorithms.

"We are also taking aggressive action on comments, launching new comment moderation tools and in some cases shutting down comments altogether", she said.

"Because we have seen these positive results, we have begun training machine-learning technology across other challenging content areas, including child safety and hate speech", she said.

The chief executive of YouTube has vowed to hire more staff and use cutting-edge machine learning technology to continue its fight against violent and extremist content.
