KISTI (Korea Institute of Science and Technology Information) and MOJ (Ministry of Justice of Korea) have provided a W3C Semantic Web Case Study on an intelligent Legislation Support System (iLaw). The system integrates legislation texts and academic articles from the USA, Japan, the European Union Countries, and Korea using Semantic Web technologies. Using locally developed ontologies, iLaw provides further relationships, shows trends and related hierarchical information connected with a legal term to local government departments; in doing so, iLaw helps legislators to review bills or legal cases in a wider, more comprehensive and international legal framework.
