SoBigData applications span multiple domains where human behaviour and complex systems generate large-scale digital traces. They include social media and news analysis to track debates and misinformation; mobility and transportation analytics to optimize flows and infrastructure; financial and economic monitoring to study markets, consumption, and inequality. Other applications address health and epidemics, disaster response, and environmental risks by combining mobility, sensor, and administrative data. Across these areas, SoBigData provides reusable datasets, methods, and research spaces that translate advanced data science into decision support for policymakers, businesses, and civil society.
