Crowdsourced Databases: Query Processing with People
Summary: Presents Qurk, a crowdsourced DBMS that exposes humans on MTurk as query operators to perform filtering, sorting, joining, and aggregation via HIT workflows. Analyzes execution and optimization challenges unique to human-in-the-loop queries—cost/latency/accuracy tradeoffs, batching, operator design, and techniques to minimize HITs and improve result quality.
