This case study was produced in cooperation with Brainspace
To support a litigation case involving breach of contract, CDS was hired to deploy technology assisted review capabilities in order to meet a tight production deadline.
Challenge: “Low Richness Makes It Hard to Find the Signal in the Noise”
After collecting email data from five key custodians and running agreed-upon search terms, the firm was left with approximately 125,000 documents for review. The firm agreed to make rolling productions and, following some sampling, knew that the agreed upon search terms would return mostly false positives. Using industry-standard estimates for contract attorneys, linear review of 125,000 documents could cost $140,000 to $150,000. Worried they might fall behind production schedule, the law firm inquired about CDS’s technology assisted review capabilities.
Using Brainspace, the leader in advanced eDiscovery data analytics, a small sample of 400 documents was reviewed and used to train a Continuous Multimodal Learning (CMML) model. CMML is an integrated set of features designed to support flexible interactive supervised learning workflows. The Predictive Ranks from the CMML model were then used to prioritize review ensuring the most relevant documents were reviewed first. Additionally, Brainspace’s patented Diverse Active Learning was used to build a small training round from a widely diverse data set to ensure that no pockets of relevant documents had been missed.
By using Brainspace’s Continuous Multimodal Learning, CDS was able to help their client reduce the review population to 70,000 from 140,000, a 50% reduction in review volume. In addition, CMML produced an initial 75% richness level in a low richness data set. With CMML, CDS and their client were able to find more relevant content faster, while reviewing far fewer documents. Together they were able to save approximately 1,750 hours of review time. By leveraging Brainspace CMML, CDS was able to meet the tight deadline – and save their client over $70,000 in attorney review fees.
