E-Discovery Triage: Using AI to Prioritize Document Review Queues
E-discovery document review is one of the most expensive phases of civil litigation. AI relevance ranking, concept clustering, and privilege flagging can dramatically reduce the number of documents human reviewers must examine, while maintaining defensible review methodology.

E-discovery economics
Document review in complex civil litigation can cost hundreds of thousands of dollars — sometimes millions — in attorney time reviewing large collections of electronically stored information (ESI). Technology-Assisted Review (TAR), also called predictive coding, uses AI to rank documents by likely relevance, allowing human reviewers to focus on high-priority items. Courts in the U.S. and UK have accepted TAR as a defensible review methodology when properly implemented.
How TAR works
A seed set of documents is reviewed and coded by a senior attorney (relevant/not relevant)
The TAR system learns from the seed set and ranks the remaining documents by predicted relevance
Reviewers focus on the high-ranked documents first, working down the ranked list
Validation samples confirm the model's accuracy at stopping points
Documents below a defensible relevance threshold may be set aside without full human review
The big idea: AI relevance ranking cuts the human review burden dramatically — but the methodology must be defensible and attorney-supervised.
