Robust Local Community Detection: On Free Rider Effect and Its Elimination
Summary: Systematic analysis of metrics exposes free rider effects; a query-biased node weighting suppresses irrelevant subgraphs. Defines query-biased density, formulates QDC, analyzes its complexity, and offers efficient algorithms with extensive experiments. (summarized by gpt-5-nano on Feb 09 2026)
