Query: On Minimizing Cost in Legal Document Review Workflows   Technology-assisted review (TAR) refers to human-in-the-loop machine learning
workflows for document review in legal discovery and other high recall review
tasks. Attorneys and legal technologists have debated whether review should be
a single iterative process (one-phase TAR workflows) or whether model training
and review should be separate (two-phase TAR workflows), with implications for
the choice of active learning algorithm. The relative cost of manual labeling
for different purposes (training vs. review) and of different documents
(positive vs. negative examples) is a key and neglected factor in this debate.
Using a novel cost dynamics analysis, we show analytically and empirically that
these relative costs strongly impact whether a one-phase or two-phase workflow
minimizes cost. We also show how category prevalence, classification task
difficulty, and collection size impact the optimal choice not only of workflow
type, but of active learning method and stopping point.
