Bruce Hedin, Ph.D.

Principal Scientist

Bruce Hedin is H5’s Principal Scientist. At H5 Dr. Hedin’s areas of focus have been process design, sampling, and metrics. Previously, Dr. Hedin worked at YY Technologies, a firm developing natural language processing software. His publications include “Domain Analysis and Representation” in The Handbook for Language Engineers (2003), and “Searching in all the Wrong Places: The Effectiveness of Search Tools in E-Discovery,” Digital Discovery & e-Evidence (January 2007). Dr. Hedin is a member the Sedona Conference’s Electronic Document Retention and Production Working Group (WG1). In 2007, he was invited to serve as a coordinator for the TREC Legal Track benchmarking initiative under the auspices of the National Institute of Standards and Technology at the United States Department of Commerce and has served in that role since then. Dr. Hedin received a B.A. from Cornell University and a Ph.D. from Stanford University.

Dr. Hedin designs and oversees the execution of measurement protocols that enable H5’s clients to demonstrate that they have met their production obligations. More specifically, the protocols that Dr. Hedin designs provide statistically-sound quantitative measures of the extent to which a producing party has in fact retrieved and produced the documents it was legally bound to produce in a lawsuit or investigation; those measures provide straightforward answers to the questions at the heart of discovery disputes: has the producing party produced all of the documents responsive to the governing request? And has the producing party avoided burdening its production with documents not responsive to the request? Dr. Hedin has implemented these protocols in a wide range of matters over the course of his ten year tenure at H5 and, as called for in any given matter, has participated in meet-and-confer discussions with opposing counsel or provided testimony on H5’s methods.

In 2007, following from his experience in measuring the effectiveness of retrieval systems, Dr. Hedin was invited to serve as a coordinator for the TREC Legal Track benchmarking initiative under the auspices of the National Institute of Standards and Technology at the United States Department of Commerce. In that capacity, in which he served until the conclusion of the track in 2011, Dr. Hedin designed and oversaw the execution of evaluations that resulted in objective measures of the effectiveness of both commercial and academic information retrieval tools and methods when applied to problems in legal discovery. Dr. Hedin is a member the Sedona Conference’s Electronic Document Retention and Production Working Group (WG1) and serves on the Program Committee for the International Conference on Artificial Intelligence and Law (ICAIL).
