Facebook chief executive officer Mark Zuckerberg will spend 2018 trying to correct persistent problems - including the proliferation of hate speech and misinformation - that have dogged his wildly popular social network for the past two years.

"We won't prevent all mistakes or abuse," Zuckerberg said in a Facebook post on Thursday morning (Friday AEDT), announcing his annual personal challenge. "But we currently make too many errors enforcing our policies and preventing misuse of our tools."

He vowed to take a comprehensive look at Facebook's role in society, recruiting experts and using his personal time to closely study issues that he said "touch on questions of history, civics, political philosophy, media, government, and of course technology". Facebook declined to make Zuckerberg available for an interview.
