AI Approaches to the Complexity of Legal Systems

topology, since the set of nodes with highest degree represents the main core of thetaxonomywith the shortestaveragedistance-concepts.The domainofmul- system and multi-lingual ontologies o?ers the opportunity to integrate arti?cial intelligence not only with legal theory,but also with further, more empirical and comparative, legal studies. The relation of legal ontologies, multi-agent systems, and distributed n- works, is only one, albeit important, among many other examples of research in AI and law. The aim of the AICOL workshops is thus to o?er e?ective support for the exchange of knowledge and methodological approaches between scholars from di?erent scienti?c ?elds, by highlighting their similarities and di?erences. The comparison of multiple formal approaches to the law such as logical m- els, cognitive theories, argumentation frameworks, graph theory, game theory, as well as opposite perspectives like the internal and the external viewpoints should stress possible convergences, as for instance in the realms of conc- tual structures, argumentation schemes, emergent behaviors,learning evolution, adaptation, and simulation.

Giovanni Sartor is Marie-Curie Professor of Legal Informatics and Legal Theory at the European University Institute of Florence and Professor of Computer and Law at the University of Bologna (Italy), after obtaining a PhD at the European University Institute (Florence), working at the Court of Justice of the European Union (Luxembourg), being a researcher at the Italian National Council of Research (ITTIG, Florence), and holding the chair in Jurisprudence at Queen s University of Belfast (where he now is honorary professor). He is author of ten books and has published widely in legal philosophy and legal theory, legal informatics (artificial intelligence and law), computational logic, legislation technique, and computer law.

Klappentext

The inspiring idea of this workshop series, Artificial Intelligence Approaches to the Complexity of Legal Systems (AICOL), is to develop models of legal knowledge, concerningorganization, structure and content, in order to promote mutual understanding and communication between different systems and cultures.Complexity and complex systems describe recent developments in AI and law, legal theory, argumentation, the Semantic Web, and multi-agent systems. The aim of the AICOL workshops is thus to offer effective support for the exchange of knowledge and methodological approaches between scholars from different scientific fields, by highlighting their similarities and differences. The comparison of multiple formal approaches to the law (such as logical models, cognitive theories, argumentation frameworks, graph theory, game theory), as well as opposite perspectives like internal and the external viewpoints, this volume stresses possible convergences, as, for instance, are possible in the realms of conceptual structures, argumentation schemes, emergent behaviors, learning evolution, adaptation, and simulation.This volume assembles 15 thoroughly refereed and revised papers, selected from twoworkshops organized at the XXIV World Congress of Philosophy of Law and Social Philosophy (IVR, Beijing, China, September 15-20, 2009) and at JURIX-09 (December 16-19, 2009, Rotterdam). The papers are organized in topical sections on language and complex systems in law, ontologies and the representation of legal knowledge, argumentation and logics, as well as dialogue and legal multimedia.
