✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on eight benchmark datasets demonstrate consistent improvements over seven representative counterparts, with gains of 19-27%.

C2weakest assumption

That LLM-generated descriptions of attribute values provide reliable, unbiased semantic knowledge that meaningfully complements the original categorical metric space without introducing hallucinations or domain mismatches.

C3one line summary

ARISE integrates LLM-generated semantic embeddings with categorical data representations to bridge the similarity gap, achieving 19-27% gains over seven baselines on eight benchmark datasets.
