Abstract: A computer program for automatic extraction of case summaries and dispositions from the decisions of legal courts is now operational. The level of performance of this program known as LEXtractor is high. In a recent computer run, LEXtractor scanned the full texts of 249 reported cases (some 650,000 words of text) and extracted correctly 92% of case summaries (15 false drops occurred) and 93% of case dispositions (no false drops occurred). This paper outlines the structure of LEXtractor, describes and analyzes its cost and performance, and discusses some relevant issues in text editing.
