Quick Note on Terminology
In this survey we're defining "TAR" as "traditional TAR": categorization (1.0) or active learning (TAR 2.0). We're using "GenAI" to mean a Generative AI-based review process (e.g. aiR, eDiscovery AI). In many important respects, GenAI can also be (or is) considered a form of TAR, but, here, we're just using "TAR" to mean "traditional TAR", to avoid any confusion.
