Building Language Technologies for Better Online Communities

Abstract:
We live in an era where many aspects of our daily activities are recorded as textual and activity data, from social media posts, to medical and financial records, to work activities captured by Wikipedia and other online tools. My research combines techniques in natural language processing, machine learning and theories in social science to study human behavior in online communities, with the goal of developing theories and systems to build better socio-technical systems. In this talk, I will explain my research from two specific studies. The first one studies what makes language persuasive by introducing a simple semi-supervised neural network to recognize persuasion strategies in loan requests on crowdfunding platforms.  The second focuses on modeling how people seek and offer support via language in online cancer support communities and building interventions to support patient communication.  Through these two examples, I show how we can accurately and efficiently model human communication to build better social systems.
