Final Report: Privacy-Protected Environment for Gathering and Analyzing Social Information Spread (PEGASIS)

DARPAs Computational Simulation of Online Social Behavior program (SocialSim) sought to develop innovative technologies for high-fidelity computational simulation of online social behavior, focusing primarily on information spread and evolution within and across social media platforms. The Leidos team provided continuous and continually growing support to DARPA Social Sim from program inception in 2017 through the end of the program in 2022. Originally established as the Data Provisioning team, Leidos was responsible for data gathering and anonymization, data enrichment, gold standard ground truth delivery, and coordination with the Test and Evaluation team on challenge problem development. By mid-2019, Leidos assumed lead responsibility for challenge problem scenario development, to align the program more clearly with DoD missions and potential end-users. In mid-2020,our role on the program again expanded to include test and evaluation, the development of a visualization user interface, and the organization of outreach engagements with potential transition partners.
