RC-Index: Diversifying Answers to Range Queries
Summary: RC-Index is an index structure for diversifying answers to general range queries over a single relation, avoiding enumeration of all valid results. It reduces retrieval substantially while providing strong approximation guarantees—the first index-based range-query diversification method with such guarantees.
