Entity Matching Using Generative AI

December 27, 2024

Business Challenge

Situation

A leading healthcare organization faced significant challenges in matching records to ensure correctness and completeness of data. The existing system relied on basic fuzzy matching techniques and manual efforts, which were:

Inefficient

Only 15-20% of records were matched automatically, leaving 80% to be processed manually.

Error-prone

Manual matching increased the likelihood of inconsistencies and errors.

Time-consuming

Processing 100,000 to 150,000 records weekly required considerable resources, leading to operational inefficiencies and delays.

As the volume of records continued to grow, it became imperative to adopt a forward-thinking solution to improve data matching accuracy, reduce manual intervention, and ensure scalability for future demands.

Goals

The primary goals were:

Achieving high accuracy in matching while minimizing false positives.
Reducing the manual effort required for data processing.
Creating a scalable and sustainable solution that integrates seamlessly with existing workflows.
A cutting-edge, AI-driven solution was implemented to revolutionize entity matching. The approach included:
