Abstract

LawProp is an online tool that extracts and displays the key “legal propositions” expressed by judicial opinions. These propositions are quite simply the passages of an opinion that are quoted directly by other, subsequently issued opinions. By analyzing these subsequent quotations it is possible to create a database of legal propositions containing measures of importance and relatedness. Furthermore it is possible to automatically generate and display useful “headnotes” for opinions without a manual editorial process.
