Ed-Join: An Efficient Algorithm for Similarity Joins With Edit Distance Constraints
Summary: EdJoin leverages mismatch-based q-grams to derive two novel edit-distance lower bounds, enabling tighter filtering for similarity joins under edit-distance constraints. It dramatically reduces candidate sets and runtime, outperforming prior q-gram–based approaches on large real datasets. (summarized by gpt-5-nano on Feb 09 2026)
