Introduction to Gen AI in Legal Document Review

• Gen AI is transforming legal workflows, especially document review, by automating tedious, high-volume tasks and increasing efficiency and accuracy.

• Legal professionals see document review as the area most impacted by Gen AI, with 81-92% of poll respondents highlighting its significance.

• Key challenges in document review include growing data volume, time and cost constraints, and inconsistent human accuracy.

AI Methodologies and Large Language Models (LLMs)

• AI in legal review uses both unsupervised (e.g., clustering, anomaly detection) and supervised (e.g., TAR) learning.

• LLMs are trained on vast human-generated data and excel at extracting and processing text, but require clear, specific instructions.

• LLMs can be literal and context-dependent, making instruction clarity crucial for optimal results.

Gen AI vs. Traditional Review Processes

• Both human and Gen AI-powered reviews start with protocols and iterative quality control, but Gen AI enables rapid, scalable review with measurable recall and precision.

• TAR learns from examples provided by users, while Gen AI follows natural language instructions to identify relevant documents.

• Gen AI offers transparency by providing explanations for each tagging decision, aiding in process validation and improvement.
