Scaling Similarity Joins over Tree-Structured Data
Summary: Dynamic decomposition of tree objects into threshold-guided subgraphs, enabling pruning without computing full tree edit distance when no common subgraph. Two-layer subgraph index yields scalable similarity joins, delivering up to an order-of-magnitude speedup over prior methods on real and synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
