Facebook News Feed Integrity, by Lluís Garcia-Pueyo (Engineering Manager, Facebook). July 10th, 15:30h, room 55.309

Abstract: 

Facebook goal with News Feed is to show people the stories that matter most to them, every time they visit Facebook. News Feed is a personalized, ever-changing collection of photos, videos, links, and updates from the friends, family, businesses, and news sources they've connected to on Facebook. People on Facebook value meaningful, informative stories, and accurate and authentic content. Integrity teams within Facebook are responsible to maintain and enforce Community Standards that reflect our collective values for what should and should not be allowed on the platform. In this talk, I'll give an overview of how the News Feed works, and how we enforce Integrity in the News Feed, as well as the challenges in combining maximizing relevance while minimizing bad experiences.
