Technological advances have democratized the analysis of huge suites of material culture data, providing the necessary framework for large-scale regional studies of social interaction. As the only tangible archaeological signature of social activity, material culture is a crucial aspect of archaeological studies of community interaction across time and space. The goal of this session is thus to present a range of approaches that employ big data to model community interaction through spatial and temporal analyses of material culture at the regional scale. Submissions from graduate students are encouraged.
