How to achieve equity in science and technology communication is a core issue across social science and STEM disciplines. In this seminar, Chen will first share her work that employs various computational social science methods (e.g., NLP, Computer Vision, Network Analysis) to uncover the sociopolitical mechanisms involved in excluding certain communities’ voices in computer-mediated communication, from digital public spheres to the emerging conversational AI systems. Chen will then introduce how to design deliberative technologies, drawing from theories in deliberative democracy and social computing, to empower under-served communities in science and technology policymaking.
