GoldenMatch is an advanced entity resolution toolkit designed to deduplicate records, match data across diverse sources, and synthesize accurate golden records. It works efficiently on files or live databases.

Can GoldenMatch handle sensitive or private data matching?

Yes, GoldenMatch features Privacy-Preserving Record Linkage (PPRL) with auto-configured bloom filters, enabling secure record matching across organizations without sharing raw Personally Identifiable Information (PII).

How does GoldenMatch ensure high accuracy in data matching?

It leverages Fellegi-Sunter probabilistic matching with EM-trained probabilities, offers an optional LLM scorer for enhanced accuracy on challenging product matching tasks, and supports active learning to refine results.

What are the primary ways to use GoldenMatch?

GoldenMatch supports zero-config operation with auto-detection, a comprehensive Python API, an interactive TUI, and integrations with dbt, databases (Postgres, Snowflake), and cloud storage, making it highly versatile.

Deduplicate records, match across sources, and maintain golden records using advanced entity resolution techniques.

GoldenMatch is a comprehensive entity resolution toolkit engineered to deduplicate records, match data across disparate sources, and synthesize authoritative golden records. Built with high-performance libraries like Polars and RapidFuzz, it offers a zero-configuration mode for immediate use, automatically detecting data types and selecting optimal scoring methods. For complex datasets, it incorporates optional LLM (Large Language Model) boosting and Fellegi-Sunter probabilistic matching to achieve high accuracy at minimal cost, running efficiently on files or live databases.
