# Exact Match

## Definition of Exact Match

Exact Match: Exact match is a term used in data science to describe a type of search algorithm that compares two strings of text and determines whether or not they are an exact match.

## What is an Exact Match used for?

An Exact Match is a type of data matching algorithm used to compare two strings of text or other data elements and determine whether they are exactly the same or if there are any differences. This type of algorithm is commonly used in machine learning and data science applications to detect fraud and duplicate records. For example, an Exact Match can be used to compare customer records from different databases and identify whether two customers have the same name, address, phone number, email address etc. An Exact Match algorithm will take these pieces of information as input and look for exact matches between them. It then outputs a comparison score that indicates how closely the two strings match each other; the higher the comparison score, the more likely it is that the two strings are an exact match. In addition to fraud detection, this type of algorithm can also be used for tasks such as clustering similar documents by their content or finding similar products in online stores. As its name implies, an Exact Match algorithm requires exact matches between two strings in order to yield accurate results – anything else will be flagged as a mismatch.
