In-context Clustering-based Entity Resolution with Large Language Models: A Design Space Exploration

Summary: In-context clustering: prompt LLMs to cluster record sets directly (vs pairwise), reducing API calls/time and improving scalability. LLM-CER maps the design space (set size, diversity, ordering), adds cluster-merging and hallucination mitigation, yielding up to 150% accuracy gains and 5× fewer API calls.
