Generalized Entity Matching with Adaptivity via Large Language Models
Unlocking Enterprise AI Potential
This research presents GLEAM, an end-to-end unsupervised framework for generalized entity matching that dynamically adapts to data structure and domain characteristics, leveraging large language models (LLMs). It achieves up to 25.7% F1 improvement over state-of-the-art supervised methods while maintaining high efficiency across diverse, heterogeneous datasets. This significantly reduces the need for costly labeled data and manual tuning in complex data integration scenarios.
Executive Impact Summary
GLEAM's advancements translate into tangible benefits for enterprise data management, offering unprecedented efficiency and adaptability in complex data environments.

LLM-Guided Blocking
GLEAM introduces an LLM-guided structural weighting scheme that incorporates attribute importance into a heterogeneous graph, enabling adaptive blocking without labeled data. This ensures high-recall candidate generation even with schema heterogeneity.
90%+ Recall in BlockingAdaptive Matching Flow
A novel adaptive connector dynamically adjusts matching thresholds based on proximity scores and real-time feedback from the LLM, optimizing computational efficiency by preventing unnecessary LLM calls.

Hierarchical LLM Reasoning
The framework uses a two-stage LLM approach: triage identifies domain and attribute hierarchies, and a domain expert LLM performs comparative selection. This adaptive prompting ensures robust matching across diverse schemas.

Significant Cost Reduction
On datasets like SEMI-TEXT-W, GLEAM maintains a flat token cost of 143M, whereas baselines like ComEMmatch and GLEAMmatch grow from 4.9M to 396M and 7.7M to 419M, respectively. This represents a 75%+ reduction in token consumption by dynamically controlling exploration depth.
