A Scalable Index for Top-k Subtree Similarity Queries
Summary: Scalable top-k subtree similarity via inverted lists; processes subtrees first and supports incremental updates in linear space. Tuning-free, data-type agnostic; outperforms state-of-the-art indexes in time and memory, up to four orders of magnitude. (summarized by gpt-5-nano on Feb 09 2026)
