In the ever-evolving landscape of data management, the challenge of maintaining accurate and consistent records across various databases is a common hurdle for many organizations.

This is where the concept of entity resolution becomes pivotal, particularly when blending data from diverse sources.

But what exactly is entity resolution, who needs it, and how can DataWalk streamline this process?

Let’s delve into these questions.

What is Entity Resolution?

At its core, entity resolution is the process used to identify, link, and merge records from one or more datasets that correspond to the same real-world entity, such as a person or a company.

Given the vast amounts of data generated and stored in different formats, it’s not uncommon to find multiple, varying records for a single entity. The challenge lies in accurately determining whether these records represent the same entity or different ones.

Example of Entity Resolution in Action

Imagine encountering multiple records with slight variations in names, addresses, or phone numbers. For instance, “Robert Smith” at “123 Main Street” in one record might appear as “Rob Smith” at “123 Main St.” in another. The process of entity resolution evaluates such records, considering discrepancies and similarities, to ascertain if they indeed refer to the same individual.

Who Benefits from Entity Resolution?

For companies, a comprehensive understanding of their customer base is crucial. Entity resolution aids in achieving a 360-degree view of customers by correlating fragmented data across multiple sources.

Law Enforcement and Anti-Fraud Agencies:

These organizations leverage entity resolution to detect and investigate instances of fraud, identity theft, and other deceptive practices by linking disparate pieces of information.
