 In Data Matching

record linkageLet’s begin by answering a simple question- what is record linkage?

Record linkage is the capacity to find duplicate entries in large data sets. For example, duplicate entries could represent people in one or more customer databases. Also, it could represent items in your stock systems. It enables you to find them and take actions. For example, you can merge two identical records into one. Also important, it can help you identify the entries that actually are not duplicates.

How Does Record Linkage Work?

To put it simply, record linkage relies on finding unique identifiers. A unique identifier is a property that, most likely, is not going to change in the future. However, it is not so simple. Why? Becuase, in reality, things do change over time. So, the most important aspect is to identify the properties that can’t change. For people, it could be the date of birth, height, and gender. For objects, it could be shape or size.

There are two main methods of record linkage:

  • deterministic: it is determined by the number of matching identifiers
  • probabilistic: it is determined by the probability that a certain number of identifiers match

Benefits of Record Linkage

The most important benefit that record linkage brings is that it helps companies build a single customer view. Without record linkage,  you will find information about customers spread across different data sets and even multiple systems. Obviously, this makes it impossible to get useful insight and also makes it impossible for companies to make sound business decisions.

Record linkage provides the means for your company to always extract actionable data from databases and lists. With this data, you will be able to easily build a complete customer view. With a complete customer view, companies can significantly improve their marketing efforts, make more accurate business decisions, and increase overall customer loyalty.

Also, it is worth mentioning that record linkage plays an important role in the context of the new GDPR regulation. For example, one of the most important requirements introduced by GDPR is that companies need to ask for explicit permission in order use their customer’s e-mail addresses for marketing campaigns. However, businesses use more than one channel to interact with their customers. As a result,  it is practically impossible to ask for explicit permission when customer data is spread across various records or even systems.
