Top-k Queries over Digital Traces

Summary: Top-k queries over digital traces are accelerated with association functions, dimensionality reduction, and a hierarchical index that co-locates entities. Mobility-model pruning is analyzed and validated on real and synthetic data, outperforming baselines. (summarized by gpt-5-nano on Feb 09 2026)
