Efficient Algorithms for Answering the m-Closest Keywords Query
Summary: mCK queries are NP-hard; a 2-approx greedy algorithm is developed. Circle-enclosure yields 2/√3 and (2/√3+ε) approximations, and an exact method uses the approximate group to beat prior work, with extensive real-dataset experiments. (summarized by gpt-5-nano on Feb 09 2026)
