Prisoners' Release: Artificial Intelligence
The question
To ask the Secretary of State for Justice, what assessment he has made of the potential effectiveness of using Splink to reduce the number of prisoner released in error.
Answered by Jake Richards
Splink, a probabilistic data-linking tool, is being used to deduplicate and connect records across multiple Ministry of Justice datasets. The Core Person Record service, which links data from courts, prisons and probation, leverages Splink to improve data accuracy for real-time operational decision-making. Early testing indicates this service improves the accuracy and timeliness of person-level information available to staff. We have not yet evaluated its effectiveness on reducing prisoners release in error and agree there is potential to see an indirect impact by reducing identity confusion and ensuring warrants, licence conditions and other information is always associated with the correct individual. We will continue to explore further applications of Splink to strengthen processes, such as preventing erroneous prison releases.
