Splink
Benefits
The introduction of Splink increases the speed and accuracy of linkage. The availability of linked data has a variety of benefits such as: More reliable research and policy analysis – Analysts can now generate insights based on linked justice system data rather than fragmented datasets, supporting evidence-based decision-making. Reduction in data duplication – By deduplicating records, Splink ensures that justice system statistics and analytics reflect unique individuals rather than multiple records of the same person. Improved operational efficiency – The ability to track individuals across the justice system more accurately supports better resource allocation and case management.
