If you attended LegalTech in April, you certainly noticed the great number of vendors offering “predictive coding,” typically as part of a “technology assisted review” process intended to reduce the time and cost required for document review.

What is predictive coding? In simplified terms, predictive coding is a technology-based workflow that allows a computer application to “read” and sort or organize electronic documents. In a typical workflow, human reviewers code a limited number of random documents, and the technology applies those decisions to a much larger document set based upon patterns of relevance. Human reviewers then spot check the coded documents, creating a feedback loop that improves results.
