Kathleen Carley (School of Computer Science) says Musk’s wide reach on X helps spread false election information to other platforms, like Reddit and Telegram. She explains that X acts as a “conduit,” allowing misleading content to move easily from one social media site to another.

Further, the responses from AI conversation tools depend heavily on the text with which the model is trained, Kathleen Carley, another professor of computer science at Carnegie Mellon University. "There's this view that the majority of information that it was trained on is more left-leaning and has certain political biases and certain political agendas built into it," Carley said. "That's where that argument is coming from."
Twitter Bots Are Promising Cheap Guns to Anyone Using the N-Word

Kathleen Carley spoke to concerns that bot accounts on Twitter, using a crude form of racial profiling, were targeting specific accounts with messages promoting gun sales. “This looks like a coordinated attempt at provoking harm,” she said. “There may be multiple motivations: to sow dissension, to increase polarization, to encourage racial prejudice. All of these are achieved by these messages.”

"Kathleen Carley is a computer science professor at the Institute for Software Research at Carnegie Mellon University who has helped develop two bot-detection tools: BotHunter and BotBuster. Carley defines a bot as 'an account that is run using completely automated software,' a definition that aligns with Twitter’s own."

The 2020 (virtual) symposium, entitled “Applying Principled Leadership in Uncertain Times,” was hosted by the Tepper School of Business at Carnegie Mellon University. Featured presenters included Kathleen Carley of Carnegie Mellon, who spoke on disinformation in cyberspace, and Nicole Lindsay of the Mastercard Center for Inclusive Growth, who spoke about sustainable social impact in business. The social impact experience took place in Chicago and was focused on youth experiencing homelessness.
Researchers: Nearly Half Of Accounts Tweeting About Coronavirus Are Likely Bots

"We do know that it looks like it's a propaganda machine, and it definitely matches the Russian and Chinese playbooks, but it would take a tremendous amount of resources to substantiate that," said Kathleen Carley, a professor of computer science at Carnegie Mellon University who is conducting a study into bot-generated coronavirus activity on Twitter that has yet to be published.

Investigating coordinated account creation using burst detection and network analysis
Journal of Big Data2023
Democracies around the world face the threat of manipulation of their electorates via coordinated online influence campaigns. Researchers have responded by developing valuable methods for finding automated accounts and identifying false information, but these valiant efforts often fall into a cat-and-mouse game with perpetrators who constantly change their behavior. This has forced several researchers to go beyond the detection of individual malicious actors by instead identifying the coordinated activity that propels potent information operations.
Role of masks in mitigating viral spread on networks
Physical Review E2023
Masks have remained an important mitigation strategy in the fight against COVID-19 due to their ability to prevent the transmission of respiratory droplets between individuals. In this work, we provide a comprehensive quantitative analysis of the impact of mask-wearing. To this end, we propose a novel agent-based model of viral spread on networks where agents may either wear no mask or wear one of several types of masks with different properties (e.g., cloth or surgical). We derive analytical expressions for three key epidemiological quantities: The probability of emergence, the epidemic threshold, and the expected epidemic size.
Bridging online and offline dynamics of the face mask infodemic
BMC Digital Health2023
Online infodemics have represented a major obstacle to the offline success of public health interventions during the COVID-19 pandemic. Offline contexts have likewise fueled public susceptibility to online infodemics. We combine a large-scale dataset of Twitter conversations about face masks with high-performance machine learning tools to detect low-credibility information, bot activity, and stance toward face masks in online conversations. We match these digital analytics with offline data regarding mask-wearing and COVID-19 cases to investigate the bidirectional online-offline dynamics of the face mask infodemic in the United States.
A Weakly Supervised Classifier and Dataset of White Supremacist Language
arXiv:2306.157322023
We present a dataset and classifier for detecting the language of white supremacist extremism, a growing issue in online hate speech. Our weakly supervised classifier is trained on large datasets of text from explicitly white supremacist domains paired with neutral and anti-racist data from similar domains. We demonstrate that this approach improves generalization performance to new domains. Incorporating anti-racist texts as counterexamples to white supremacist language mitigates bias.
#WhatIsDemocracy: finding key actors in a Chinese influence campaign
Computational and Mathematical Organization Theory2023
The rapid increase in China’s outward digital presence on western social media platforms highlights China’s priorities for promoting pro-Chinese narratives and stories in recent years. Simultaneously, China has increasingly been accused of launching information operations using bot activity, puppet accounts, and other inauthentic activity to amplify its messaging. This paper provides a comprehensive network analysis characterization of the hashtag influence campaign China promoted against the US-hosted Summit on Democracy in December 2021, in addition to methods to identify different types of actors within this type of influence campaign.
