EdgeRack: Understanding the algorithmic basis of Facebook’s news feed

Reid Goldsborough describe the algorithmic basis for Facebook’s news feed, writing “The ever-changing algorithm behind Facebook’s news feed, called EdgeRank, is … crucial in today’s social media-infused world. It determines what you see when you check Facebook,” … adding … “Facebook is largely mum about EdgeRank, keeping many things private for competitive reasons. But based on what is publicly known as well as EdgeRank’s behavior, Facebook uses EdgeRank to help create your news feed mostly through Affinity Score, Edge Weight, and Time Decay.” Goldsborough proceeds by describing Affinity Score, Edge Weight, and Time Decay in layman’s terms. He also comments on the echo chamber effect of Facebook’s news feed in his Information Today article. Informative. — Joe
