Nexus: Correlation Discovery over Collections of Spatio-Temporal Tabular Data

Summary: Nexus aligns heterogeneous spatio-temporal tabular datasets in a large repository to support exploratory correlation discovery as a precursor to causal analysis. Key novelty: robust cross-dataset space/time alignment with missing-data handling plus ranking of “interesting” correlations, validated on Chicago open data and UN datasets.
