Abstract

Translate

A computer program for automatic extraction of case summaries and dispositions from the decisions of legal courts is now operational. The level of perform- ance 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.
