Mining Social Media

Abstract: Social media holds the promise of a vast dataset that represents “what people think” about various issues. This talk covers several social media applications in various domains, including economics, politics, public health, and emergency management. A particular focus are sudden-onset events such as natural disasters or mass convergence events. We also discuss various biases that affect this research and ethical boundaries that delimit it.
