Keyword-aware Optimal Route Search
Summary: Defines keyword-aware optimal route (KOR) queries requiring keyword coverage, a travel budget, and optimal route objective; KOR is NP-hard. Proposes OSScaling with provable bounds, plus BucketBound and Greedy variants; empirical results show scalable, fast solutions with bounded approximation. (summarized by gpt-5-nano on Feb 09 2026)
