Legal entity recognition in an agglutinating language and document connection network for EU Legislation and EU/Hungarian Case Law
We have developed an application aiming atfederated search for EU and Hungarian legislation andjurisdiction. It now contains above 1 million documents, withdaily updates. The database holds documents downloadedfrom the EU sources EUR-Lex and Curia Online as well aspublic jurisdiction documents from the Constitutional Courtof Hungary and The National Office for The Judiciary. Theapplication is termed Justeus. Justeus providescomprehensible search possibilities. Besides free text andmetadata (dropdown list) searches, it features hierarchicaldata structures (concept hierarchy trees) of directory codesand classification as well as subject terms. Justeus collects alllinks of a particular document to other documents (courtjudgements citing other case law documents as well aslegislation, national court decisions referring to EU regulationetc.) as tables and directed graph networks. Choosing adocument, its relations to other documents are visualized inreal time as a network. Network graphs help in identifying keydocuments influencing or referred by many other documents(legislative and/or jurisdictive) and sets of documentspredominantly referring to each other (citation networks).
