- Conference PaperSupporting High-Stakes Investigations with Expert-Led Crowdsourcing(Companion Proceedings of the 2023 ACM International Conference on Supporting Group Work, 2023) Venkatagiri, SukritMy dissertation introduces the concept of expert-led crowdsourcing (ELC) to support expert investigators who increasingly face limits on their time and attention. ELC combines experts’ domain knowledge and experience with the speed and scale of crowds. I study ELC in two investigative domains: journalism and law enforcement. Through four studies, I show: 1) how novice crowds can effectively augment expert investigators’ work practice; 2) the ethical tensions in conducting an ELC investigation for real-world, sensitive investigations; 3) how capture-the-flag competitions increase inter-team collaboration in ELC investigations; and 4) how different teamwork structures affect intra-team collaboration in ELC investigations.
- Conference PaperUnderstanding Young People’s Assessment of Social and Automated Approaches to Misinformation Remediation(Companion Proceedings of the 2023 ACM International Conference on Supporting Group Work, 2023) Shusas, EricaThe massive, rapid, and pervasive spread of mis- and disinformation on social media has been hailed by many as a threat to democratic processes and human rights across the globe. Young people are particularly vulnerable to this threat due in part to their proportionally high consumption of news through social media platforms. My dissertation aims to better understand how young people engage with flags to misinformation from sources such as social cues and automated tools in order to offer insights into how to build better credibility assessment tools.
