TV News Archive - Multimodal Topic Detection

Introduction

TV has been the most influential news channel for decades. Understanding its behaviors and impacts is a core problem in communication and journalism, but it has been challenging to manage the massive amount of multimodal data. Our goals in this project are to develop a fully-automated computational pipeline to process news videos by large-scale computer vision, machine learning, and NLP techniques, to detect news events, actors, sentiments, topics and their associations, and to systematically quantify the characteristics and effects of the mass media such as media bias or agenda-setting.
