12.5TB of data processed and reviewed within 7 days for regulatory collusion case

Salient uses innovative parallel processing techniques, AI and keyword search to rapidly and accurately surface 2500 responsive documents out of an initial dataset of 12.5TB.

Client Sector: Large Insurance Firm
Technology Used: AI eDiscovery

The Challenge

Large data volumes, tight timelines, limited budget

Salient was recommended to the client (a large insurance company) by their law firm. They approached us to assist in a regulatory collusion case with large volumes of data (12.5TB) resulting from a wide date range.

The client and their legal counsel hoped to optimise the time- and cost-implications of the large data volumes through intelligent culling in order to remain in-budget and one step ahead of the regulator.

Our Solution

Parallel pre-processing, processing and review

Salient ran the data through pre-processing to deduplicate and de-NIST it, applying filters to move it onwards to processing in the eDiscovery platform. Pre-processing was done in parallel with processing and moving data on to review. This enabled us to significantly reduce overall processing times.

AI for ECA and keyword search

AI was then utilised for early case assessment (ECA), along with keyword search to surface responsive documents.

Outcome

Rapid turnaround at a reduced cost with ongoing investigation in progress

From data collection to review, Salient successfully dealt with six priority custodians in 7 days, reducing 15 million documents to just 7 million documents within a week of ingestion into Reveal. Keyword search surfaced 2500 responsive documents, enabling the client to achieve their goal of fast, cost-effective preliminary insight into the suspected regulatory collusion matter.

The investigation is ongoing and Salient continues to assist the client by using Reveal’s AI capabilities to gain insights through the identification of cluster wheels, similar concepts, entities and players, and interactions outside the organisation.
