Characterizing and Selecting Fresh Data Sources
Summary: Dynamic source selection for data integration; introduces time-dependent metrics (coverage, freshness, accuracy) and statistical models to estimate them. Despite NP-hardness, presents a near-optimal algorithmic framework with theoretical guarantees, validated on real and synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
