Online interactions can range from an inconsequential ‘like’ of a friend’s post or picture to nationally important conversations between citizens and their elected representatives. In this talk I will describe a number of machine learning and data analysis-based approaches to answer three high level questions: </div> <div> 1. What can social network interactions tell us about ourselves? </div> <div> 2. How can we co-ordinate disparate and independent user actions to learn new information about the content being generated? </div> <div> 3. Are online conversations bring us together or driving us apart? </div> <div> <br /> </div> </div> <div class="row lecture__section"> <h2>About this Lecture</h2> <span> <strong>Number of Slides:
