'Misinformation and disinformation on the web are problems we face as a society, and this book is for anyone looking for hope for the future! Well-regarded authors in various disciplines contribute enjoyable and informed chapters on theoretical accounts of perspectives and how they work, practical methods for discovering and measuring bias, and computational procedures for identifying and fixing perspectives at web scale with consistent and reliable results.' Eduard Hovy, Carnegie Mellon University
