A typical business stores data across multiple systems, including ERPs for operations, a CRM for marketing, files, notebooks, and BI apps for other purposes. Records of the same customer (entity) exist in multiple places, likely not in sync across nor unique within sources. This inconsistent situation generates an opportunity for us to drive business value by cross-referencing and deduplicating records with entity resolution.

This course covers business acumen and hands-on coding. It starts with several business cases and a quick introduction to entity resolution in Python. Then, it explores semantic-preserving preprocessing, similarity feature engineering, graph clustering, weak supervision, confident learning, and integration.

As a developer, you’ll increase your company’s business value by developing and deploying entity resolution pipelines. As a decision-maker, you’ll know which solution best suits your business cases and how to negotiate the best value for your money.

An Introduction to Entity Resolution in Python

This lesson is about how to put resolved data into action to improve decision-making. The `restaurants` data contains customer records with hidden duplicates. The `cross_ref` table encodes our resolution. It is time to use the resolved data and address the needs of the business.

Our `cross_ref` table covers only those original customer IDs with at least one match. We parse the values to strings and expand that table to cover all restaurants for joining with transactional data.

Utilize resolved restaurant records to support marketing campaigns with insights.
