 A theory‐driven machine learning system for financial disinformation detectionXiaohui Zhang, Qianzhou Du and Zhongju Zhang Production and Operations Management, 2022, vol. 31, issue 8, 3160-3179 Abstract: Maliciously false information (disinformation) can influence people's beliefs and behaviors with significant social and economic implications. In this study, we examine news articles on crowd‐sourced digital platforms for financial markets. Assembling a unique dataset of financial news articles that were investigated and prosecuted by the Securities and Exchange Commission, along with the propagation data of such articles on digital platforms and the financial performance data of the focal firm, we develop a well‐justified machine learning system to detect financial disinformation published on social media platforms. Our system design is rooted in the truth‐default theory, which argues that communication context and motive, coherence, information correspondence, propagation, and sender demeanor are major constructs to assess deceptive communication. Extensive analyses are conducted to evaluate the performance and efficacy of the proposed system. We further discuss this study's theoretical implications and its practical value.
