Facebook boss Mark Zuckerberg has said his personal challenge for 2018 is to "fix" the social site and how it handles hate, abuse and fake news.
The social network platform's founder said the firm was making "too many errors" when enforcing its policies and stopping misuse of the site.
The platform has been repeatedly criticised in the past year for its attitude to removing extreme and abusive content, and faced questions over the role and ease with which fake news is able to spread.
Mr Zuckerberg said he wanted the year to be one of "self-improvement" for the social site, but stopped short of announcing any clear policy plans.
"Facebook has a lot of work to do - whether it's protecting our community from abuse and hate, defending against interference by nation states, or making sure that time spent on Facebook is time well spent," he said.
"My personal challenge is to focus on fixing these important issues. We won't prevent all mistakes or abuse, but we currently make too many errors enforcing our policies and preventing misuse of our tools."
