From a list of words:

< activity, civil action, proceeding, legal proceeding, judicial proceeding, criminal procedure, administrative procedure,civil law suit;

To a structured vocabulary:Synset:a set of words that can be interchanged in a given context

JurWordNet: a Descriptive Vocabulary for Legal

Information

It is Semantic lexicon for law: extension to the legal area of the Italian part of the EuroWordNet initiative;

Methodology: - bottom-up approach; identification of the legal

relevant terms from lexical resources and from the main legal information sources;

- definition of synsets by semantic relations; - plug-in to the Italian WordNet

JurWordNet


Furore April 6-8

Jur-WordNetFigures:

1000 relevant literals selected from the Italian legislation (15,600 of 33,000 with a Italgiure’s frequency index between 15,000 and 25,000)

2000 syntagms from the 13.372 Italgiure’s syntagms automatically imported and structured

from 6495 key words of DOGI (Data bank on Legal Jurisprudence mapped into the JurWordNet DB: 486 terms overlapping, 315 new terms, 2223 syntagms automatically imported.

Objectives (general)

• Localization of WordNets for the legal domain in Italian, English, German, Czech, Portuguese and Dutch;

• Link among concepts to enable cross-lingual access.


Furore April 6-8

Objectives (User)

• Access to legislative corpora by unexperienced users;

• Better retrieval by experienced users;

• Cross-lingual retrieval across different national law collections;


Furore April 6-8

Objectives (Applications)

• Multilingual source of semantic metadata for content description (conceptual standardization);

• Automatic Classification and Indexing (structuring legal entities);

• Knowledge Representation, Norms Comparison (formalization of ontological committment).

National legal WNs

• The Lexical Data Base conceptualizes general language entities pertaining to legal theory and legal dogmatics (structured according to the EWN methodology)

• The Legislative data base (EU-National Legal Concept), populated by concepts defined in European and national legislation

The Lexical Data Base(about 1600 synsets)

synsets are linked by:

• internal relations

• cross-lingual relations:eq_synonym,eq_near_synonym,eq_has_hyperonym,

eq-has_hyponym, etc.

Lexical relations (syn, antonym, near-syn)

Semantic relations (Hyper, Hypo, Part-of, Role, Instance, etc.)
