SkyGraph: Retrieving Regions of Interest using Skyline Subgraph Queries

Summary: SkyGraph retrieves Regions of Interest in keyword-embedded road networks via skyline subgraph queries, balancing RoI size and PoI relevance for on-foot vs. vehicle use. Since skyline set computation is NP-hard, it provides a polynomial-time approximation and a Partner Index to prune search space, delivering up to 10^3× speedups on real road networks.
