YouTube as a source of information: early coverage of the COVID-19 pandemic in the context of the construction industry

The COVID-19 pandemic has been the largest global crisis in recent decades. Apart from the countless deaths and health emergencies, the pandemic has disrupted several industries—including construction. For example, a significant number of construction projects have been interrupted, delayed, and even abandoned. In such emergencies, information gathering and dissemination are vital for effective crisis management. The role of social media platforms such as YouTube, Facebook, and Twitter, as information sources, in these contexts has received much attention. The purpose of this investigation was to evaluate if YouTube can serve as a useful source of information for the construction industry in emergency situations—such as during the early stages of the COVID-19 pandemic. The assessment was undertaken by distilling the coverage of the COVID-19 pandemic as it relates to the construction industry from the content shared via YouTube by leveraging Latent Dirichlet Allocation (LDA) topic modelling. The investigation also compared the timeline with which relevant content was shared via YouTube and peer-reviewed research articles to make relative assessments. The findings suggest that YouTube offered significant and relevant coverage across six topics that include health and safety challenges, ongoing construction operation updates, workforce-related challenges, industry operations-related guidelines and advocacy, and others. Moreover, compared to the coverage of the COVID-19 pandemic in the research literature, YouTube offered more comprehensive and timely coverage of the pandemic as it relates to the construction industry. Accordingly, industry stakeholders may leverage YouTube as a valuable and largely untapped resource to aid in combating similar emergency situations.
