The linked legal data landscape: linking legal data across different countries

The European Union is working towards harmonizing legislation across Europe, in order to improve cross-border interchange of legal information. This goal is supported for instance via standards such as the European Law Identifier (ELI) and the European Case Law Identifier (ECLI), which provide technical specifications for Web identifiers and suggestions for vocabularies to be used to describe metadata pertaining to legal documents in a machine readable format. Notably, these ECLI and ELI metadata standards adhere to the RDF data format which forms the basis of Linked Data, and therefore have the potential to form a basis for a pan-European legal Knowledge Graph. Unfortunately, to date said specifications have only been partially adopted by EU member states. In this paper we describe a methodology to transform the existing legal information system used in Austria to such a legal knowledge graph covering different steps from modeling national specific aspects, to population, and finally the integration of legal data from other countries through linked data. We demonstrate the usefulness of this approach by exemplifying practical use cases from legal information search, which are not possible in an automated fashion so far.

Moving Picture Experts Group (MPEG) is an ISO/IEC working group developing media coding standards. This includes a set of ontologies for the codification of intellectual property rights (IPR) information related to media. The Media Value Chain Ontology (MVCO) facilitates rights tracking for fair, timely and transparent payment of royalties by capturing user roles and their permissible actions on a particular IP entity. The Audio Value Chain Ontology (AVCO) extends MVCO functionality related to description of IP entities in the audio domain, e.g., multi-track audio and time-segments. The Media Contract Ontology (MCO) facilitates the conversion of narrative contracts to digital ones. Furthermore, the axioms in these ontologies can drive the execution of rights-related workflows in a controlled environment, e.g. blockchains, where transparency and interoperability is favoured towards fair trade of music and media. Thus, the aim of this article is to create awareness of the MPEG IPR ontologies developed in the last few years and the work that is currently taking placeaddressing the challenge identified -towards their execution as smart contracts on blockchain environments. BACKGROUND MOTIVATIONCopyright legislation has continuously evolved with the aim to revive the music industry, in terms of fair and increased revenues returned to artists and rights holders, improved multiterritory licensing, timely payments, and overall more transparency, e.g., US Music Modernisation Act [1] and EU Copyright Directive Reform [2]. Meanwhile, several key artists and musicians have turned their hopes for resolving these issues to technology and in particular, towards blockchain [3][4]. Blockchain emerged in 2008 as the technology that underpins bitcoin. It operates as a shared ledger, which continuously records transactions or information. Its database structure, where

“…Ontologies are the powerful conceptual tools that communities use to share knowledge in the Semantic Web. There are ontologies with a general vocation, covering a wide range of fields, such as those used by DBPedia 17 , schema.org 18 , etc., and ontologies more specific to a given domain, such as geographic information systems [36], [37], or to the legal domain [38]- [40]. Ontologies also provide a support for describing and linking resources based on the properties shared [41].…”

Thesauri are Knowledge Organization Systems (KOS), that arise from the consensus of wide communities. They have been in use for many years and are regularly updated. Whereas in the past thesauri were designed for information professionals for indexing and searching, today there is a demand for conceptual vocabularies that enable inferencing by machines. The development of the Semantic Web has brought a new opportunity for thesauri, but thesauri also face the challenge of proving that they add value to it. The evolution of thesauri toward their integration with the Semantic Web is examined. Elements and structures in the thesaurus standard, ISO 25964, and SKOS (Simple Knowledge Organization System), the Semantic Web standard for representing KOS, are reviewed and compared. Moreover, the integrity rules of thesauri are contrasted with the axioms of SKOS. How SKOS has been applied to represent some real thesauri is taken into account. Three thesauri are chosen for this aim: AGROVOC, EuroVoc and the UNESCO Thesaurus. Based on the results of this comparison and analysis, the benefits that Semantic Web technologies offer to thesauri, how thesauri can contribute to the Semantic Web, and the challenges that would help to improve their integration with the Semantic Web are discussed.
