David D. Lewis

The and the   will co-sponsor a talk on e-discovery, to be held on Oct. 25. The event has been organized in honor and memory of SU law professor . Hagelin passed away in May, and was an expert in technology innovation law.

Freelance computer scientist and consultant will deliver a talk titled “Machine Learning for Electronic Discovery in Legal Cases.”

Lewis will address changes in the U.S. Federal Rules of Civil Procedure and the ever-growing volume and complexity of digital data that have led to an explosion in costs for reviewing electronic documents in legal discovery (e-discovery).

A recent RAND study concluded that text classification based on machine learning (so-called “predictive coding”) is the only hope for meaningful cost reductions. Lewis will examine the history of the e-discovery crisis, what machine learning is, how it is used in discovery and the controversy around its application.

“Demands that machine learning be evaluated using statistical sampling procedures have led to their own controversies,” explains Lewis, “and I will briefly discuss these methods and their potential implications for legal practice.”

Lewis works in the areas of information retrieval, applied statistics and the evaluation of complex information systems. He formerly held research positions at AT&T Labs, Bell Labs and the University of Chicago. He has published more than 75 scientific papers and eight patents, and is a fellow of the American Association for the Advancement of Science. Lewis has served as a consulting or testifying expert on e-discovery issues in civil litigation, including in the Kleen Products, Actos, da Silva Moore, FHFA and Cambridge Place cases.

The talk is free and open to the public. It will be held at 3 p.m. Oct. 25 in Grant Auditorium in the Law School’s . A reception will follow the talk in the Heritage Alumni Lounge and Rotunda.
