The Socially Embedded Lab reimagines Social in the Digital Age.

Mission

The Socially Embedded Lab at Ben-Gurion University studies social behavior in large-scale, online information systems. The lab investigates areas where information systems are suboptimal for people -- for example, by not meeting people's needs, goals or expectations -- and proposes new computational measures to bridge the gaps. For example, it studies the scale and scope of fake news on social media and develops methods for limiting its spread, audits large-scale algorithmic systems such as Google Search and Gmail to reduce bias and inequality, and examines online user engagement with news in order to promote better measures for quantifying it. The lab is part of the Software and Information Systems Engineering (SISE) department at BGU.
