Journalism is at a crossroads. Traditionally, we have relied on news organizations to hold governments, corporations, and individuals accountable to society. In recent years, there has been an alarming trend in the increasing amount of misinformation, compared with stagnant resources and talents devoted to investigative reporting and fact-checking. Computational journalism aims at bridging this divide, by inventing computational techniques and tools to increase effectiveness and broaden participation for journalism—especially public interest journalism, to help preserve its watchdog tradition. Duke Computer Science, in collaboration with the School of Public Policy and practicing journalists, has pioneered research on computational fact-checking to help combat outrageous lies as well as factually correct but still misleading claims.
