HELIC-II: As a legal argumentation support system

Summary form only given. The authors present HELIC-II, a legal reasoning system on the parallel inference machine. HELIC-II draws legal conclusions for a given case by referring to a statutory law (legal rules) and judicial precedents (old cases). This system consists of two inference engines. The rule-based engine draws legal consequences logically by using legal rules. The case-based engine generates legal concepts by referencing similar old cases. These engines together draw all possible conclusions, and output them in the form of inference trees. Using these inference trees HELIC-II can support arguments in a legal suit. HELIC-II can draw conclusions quickly by parallel inference
