LOAIT 2010

4th Workshop on Legal Ontologies and Artificial Intelligence Techniques
Legal Concepts and Ontologies: knowledge representation, comparison, harmonization and learning

July 7th, 2010, Fiesole (Florence), Italy

held in conjunction with Deon-10

Paper submission: May 3rd, 2010 (***Extended deadline: May 16th, 2010***)


The LOAIT workshop aims to offer an overview of theories and well-founded applications that combine Legal Ontologies and AI techniques, with regard both to theories and implementations.
Over the last years the management of legal information has been significantly influenced by approaches from Artificial Intelligence (AI). In particular, legal reasoning, advanced semantic and cross-language legal information retrieval, legal drafting and document classification, have proved to be fertile areas where ontologies are successfully applied.
The first three editions of the LOAIT Workshop were held in conjunction with ICAIL Conference ('05 (Bologna), '07 (San Francisco), '09 (Barcelona)), provided a valuable opportunity for researchers and practitioners in Artificial Intelligence and Law to discuss problems, exchange information and compare perspectives on Legal Ontologies and their automatic use.
A selection of papers of LOAIT '07 were published in the volume J. Breuker, P. Casanovas, M. Klein, E. Francesconi (eds.) Law, Ontologies and Semantic Web (IOS Press, 2009), collecting state-of-the-art contributions on legal ontologies. These results point at an increasing interest of the larger AI&Law community in the study and the use of Legal Ontologies as well as in Natural Language Technologies for legal information extraction.
Recently ontology learning approaches for the legal domain were discussed in the LREC 2008 Workshop on “Semantic Processing of Legal Texts”, and selected contributions will be published in a Springer volume (Francesconi E., Montemagni S., Peters W., Tiscornia D. (eds.)). These results pointed, and still do, at an increasing interest of the larger AI&Law community in the study and the use of Legal Ontologies.
In this LOAIT edition, we would like to deal with legal knowledge modelling focusing on ontologies for legal concepts description (deontic/normative notions as well as domain concepts).
Legal knowledge modelling addresses key issues related to the support of legal reasoning. Here, ontologies play the role of a shared vocabulary or of a (formal) conceptualisation of legal notions. These ontologies often stand in the tradition of legal theory and philosophy, but may be grounded in common sense as well.
Roles of legal ontologies will be discussed as regards different applications as multilingual document annotation and drafting, multilingual legal information retrieval, legal reasoning, case-based reasoning, legal assessment, legal concepts comparison and harmonization as well as ontology learning. The ways in which ontologies are developed and used (as either bottom-up or top-down) will be addressed as well.
The workshop constitutes a valuable opportunity for researchers and practitioners in AI, AI&Law, Legal Ontologies and related fields to discuss problems, exchange information and compare perspectives.
Authors are invited to submit papers describing original completed work, work in progress, interesting problems, use cases or research trends related to one or more of the topics of interest listed below. Submitted papers will be refereed by two experts based on originality, significance and technical soundness.

Topics of Interest include but are not limited to:

  • Knowledge discovery and organization by AI approaches
  • Design Patterns in Legal Ontologies
  • Ontologies, Legal Standards and machine learning
  • Ontologies and machine learning for classification tasks
  • Text Categorization and Ontology
