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

We are humans with intuition, have prior experience with similar tasks, or did a great job preparing by reviewing the data. Now, we (believe to) know how to distinguish between a match or no-match for any pair of customer records. Let's implement this knowledge and translate it into a policy combining a few plausible rules.

Below, we define four matching rules and predict a match if any of those applies.

Combine individual scores into a match vs. no-match prediction policy using plausible rules.
