It’s the end of another month in the Mauritius Leaks saga—which, astonishingly, is the longest news-related investigation in some time. The findings so far: The secretive owner of the family-owned Freeport Du Sable, responsible for a large portion of the country’s economic activity, is currently investigating multiple allegations of misappropriation of corporate funds. Two top executives at the resort were arrested for allegedly pocketing a combined sum of $200 million. The family controls the world’s biggest nickel operation.

Here’s how Quartz, one of the early outlets investigating the offshore accounts, used artificial intelligence to help reporters hunt for additional leaks at the facility.

First, researchers had to set up a secure sandbox with two channels to compare the leaks they received in real time. Those channels did not allow unauthorized access. After that, a researcher exported a file containing a machine-learning algorithm to annotate and distinguish the leaks that were shared with Quartz with the data we received. The AI draws on methods from “computational linguistic analysis” to create linguistic human biases and perform additional work on the leaks that cannot be performed by humans. It was updated several times to capture and amend significant data until we found ones that were capable of connecting the leaks we saw on our network in real time to the rest of the Leaks network.

We have more details on this and more in a new feature on the nature of the leaks here.
