"This article aims to shed light on the infodemic of disinformation, misinformation, and malinformation in the digital era of a new normal where deepfake and fake news are omnipresent. To do so, this article establishes a general theory of information and engages in big data analytics involving a scientometrics (bibliometrics) analysis with topic modeling of the major trends in the field. In doing so, this article reveals three noteworthy findings. First, infodemic is multifaceted in terms of its content, platform, manifestation, and solution. Second, infodemic research delivers the richest insights on misinformation, followed by fake news, disinformation, infodemic solutions, and malinformation. Third, interest in the dissemination of false information is greater than its creation, with the task of ascertaining the intrinsic elements (e.g. maliciousness in disinformation and malinformation) being more challenging than that of extrinsic elements (e.g. truth of misinformation). The article concludes with implications for theory and practice as well as directions for future research." (Abstract)
