A model of normative provisions and related axioms represented by using RDF(S)/OWL are presented as a contribution to implement the semantic web in the legal domain. In particular, a pattern able to implement the Hohfeldian legal fundamental relations between provisions using OWL-DL expressivity is proposed. Moreover, a query-based approach able to deal with relations between provision instances is described. An example of advanced access and reasoning over provisions using the proposed approach, as well as a prototype architecture of a provision retrieval system, are shown. The main benefit is represented by the ability of the approach to keep the complexity of the problem within a description logic computational tractability. © 2014, Springer Science+Business Media Dordrecht.

The creation of a pan-European area of Justice is one of the leading policies of the EU: to this aim the development of e-Justice services across Europe has been promoted within the e-CODEX project. In this paper an overview of the e-Justice platform architecture developed by e-CODEX, as well as the semantic solution conceived to transmit business documents in the domain of Justice within a scenario characterized by different languages and different legal systems, are described. © 2014 Springer International Publishing.

Semantic Web | Year: 2016

A Semantic Web approach for an advanced access to legislative documents is presented in terms of a model of normative provisions and related axioms. In particular, relations between provisions are identified and modeled by introducing patterns able to describe Hohfeldian legal fundamental relations. Moreover, a query-based approach able to deal with relations between provision specific instances is described. Examples of semantic annotation of legal textual resources using RDF/OWL standards, as well as advanced access and reasoning facilities over provisions using SPARQL, are shown. The main benefit of the approach is represented by the ability to keep the complexity of the problem within a description logic computational tractability.

The paper examines the citation network of the via incidentale rulings of the Italian Constitutional Court ("ICC"), vis-à-vis the web of scholarly opinions, comments, and annotations, devoted to such cases. The aim is to deepen the notion of legal relevance. On the one hand, a remarkable number of cases that are considerably discussed by experts, are neither hubs nor authorities in the ICC citation network. On the other hand, cases that are relevant in the ICC citation network are scarcely debated, or even ignored, by scholars. This twofold outcome suggests that we should combine research on the citation network of the courts with the web of scholarly opinions, to obtain a more detailed picture of which decisions and verdicts have to be reckoned as relevant in a given legal system. © 2015 ACM.

The paper examines two different sets of rulings by the Italian Constitutional Court ("ICC"), namely the in via incidentale ("IVI"), and the in via principale ("IVP"), rulings, vis-à-vis the web of scholarly opinions ("WSO"), devoted to such cases. On the one hand, the paper shows that all such networks, i.e. IVIN, IVPN, and WSO, follow power laws patterns of informational distribution. On the other hand, this stance allows us to deepen the meaning of legal relevance. In addition to the ICC decisions widely debated by scholars, we should take into account cases that are relevant in both IVIN and IVPN and still, WSO scarcely debates them. This is the class of legal cases that scholars ignore at their own risk, since the higher a case is ranked in the citation network of the court, the higher the probability that scholars will have to reflect on such case soon. © 2015 The authors and IOS Press.
