Years after Judge Andrew Peck, US Magistrate Judge, declared it to be “black letter law” in Rio Tinto Plc v. Vale S.A., 2015 U.S. Dist. LEXIS 24996, 8 (S.D.N.Y. March 2, 2015), technology-assisted review has finally entered the mainstream among a growing suite of technology-driven eDiscovery tools. While these tools can assist practitioners with document review across large data populations, it is important to remember the critical first step of information retrieval. The traditional approaches for information retrieval no longer apply as volumes of documents continue to expand. It is important to understand that the scientific disciplines now marshalled for an effective information retrieval effort (data science, linguistics, and statistics) are essential to the successful conduct of document review. IntelligENS data scientists can assist with this crucial information retrieval task.
