In my talk, I will present a unified framework that bridges the gap between the two disciplines. The framework combines topic models, sentiment analysis, regression models and network analysis. I will present results from the political domain showing how we can detect patterns of coordinated campaigns for agenda setting, framing and political spin, based on automatic analysis of large collection of public statements made by members of the US Congress. If time (and questions) permit I’ll conclude with some initial results derived from automatic construction of political networks of cooperation and influence.  </span></span></p><p></p><p><drupal-media data-entity-type="media" data-entity-uuid="52d5ece5-d7ec-439c-9cc7-d04d77c7afee"></drupal-media></p><p><span style="font-size: 15px; line-height: 1.15; background-color: transparent;"><strong>Biography:</strong> </span></p><p></p><p style="color: #222222; font-family: arial,sans-serif; font-size: 12.8px; white-space: normal; line-height: 1.15; margin-top: 0pt; margin-bottom: 0pt; text-align: right;"><span style="font-size: 15px; font-family: Arial; color: #000000; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;"><drupal-media data-entity-type="media" data-entity-uuid="389b097e-9ace-4df2-a3ac-e4b17033af92" data-align="left" alt="Oren Tsur"></drupal-media>Oren Tsur is a postdoctoral fellow at Harvard University (SEAS &amp; IQSS) jointly with Lazer's lab at Northeastern University.
