Workshop Report

A Summary of the presentations and papers from this workshop is available here.


Recent improvements both in Human Language Technology (HLT) and in techniques for storage and rapid analysis of large data collections have created new opportunities for automated interpretation of legal text, improved access to statutory and regulatory rules, and greater insights into the structure and evolution of legal systems. These techniques hold promise for the courts, legal practitioners, scholars, and citizens alike. These advances have coincided with a rapid expansion of interest in automated processing and understanding of legal texts on the part of industry, government agencies, court personnel, and the public.

The focus of this workshop is research on and applications of that involve interpretation of legal text, analysis of structured legal documents, improved publication and access to document collections, predictive analysis based on legal text mining, and visualization of legal corpora. The intended audience for the workshop includes researchers and practitioners from industry, academia, and government working at the intersection of HLT, artificial intelligence, social science, data and network science, and law.
