Computational Social Science is the interdisciplinary science of complex social systems and their investigation through computational models and related tools. The field is at the intersection of social science and computer science and spans anthropology, economics, political science, sociology, and social psychology—the classical social sciences—as well as allied disciplines such as geography, history, organization theory, regional science, communication, and linguistics. Computational approaches include agent-based social simulation models (multi-agent systems), social network analysis, mathematical analysis based on complexity theory, social geospatial modeling methods, and automated information and content analysis methods.
