Welcome to the pages of the Leibniz Center for Law of the University of Amsterdam. As an interdisciplinary research group, we develop intelligent technology to support legal practice both in the private and in the public sector. We apply Artificial Intelligence techniques to problems in legal theory, legal knowledge management and the field of Law in general. In this capacity, we participate in many (inter)national research initiatives and maintain strong ties to the international research community and government agencies.
We have longstanding experience in the development of legal ontologies, automatic legal reasoning and legal knowledge-based systems, (standard) languages for representing legal knowledge and information, user-friendly disclosure of legal data, and the application of information technology in education and legal practice. As an academic partner, the Leibniz Center provides advice on change-management issues of knowledge-intensive legal processes and the improvement of knowledge-productivity in legal organisations.
The Leibniz Center for Law has its roots in the former department of Computer Science & Law (est. 1989) of the Law Faculty of the University of Amsterdam, and currently houses about 15 researchers.
For more background on the Leibniz Center, see our general information pages, and have a look at current projects.
The Leibniz Center for Law, together with the Institute for Information Law (IViR) and international partners, obtained a European grant for the project OpenLaws.eu.
Of the 96 proposals submitted, OpenLaws.eu finished first. The aim of the project is to use innovative resources to make law and legal information more accessible by linking and enrich these with metadata. The Leibniz Center for Law leads the consortium. Technical partners are the Fachhochschule Salzburg, Aplenite (IT) and BY WASS (Aus). IViR, together with Sussex University and the London School of Economics and Politics are
responsible for the legal and economic aspects.

The Leibniz Center for Law of the University of Amsterdam has made all Dutch legislation available as CEN MetaLex and Linked Open Data through the MetaLex Document Server portal (MDS). “The XML source documents currently made available by the Dutch government are simply not good enough”, says Rinke Hoekstra, researcher at the Leibniz Center, and the Knowledge Representation group of the VU University Amsterdam.
The MetaLex Document Server improves over the XML API of the official portal by:
- Providing persistent, versioned identifiers of all elements of regulations.
- Maintaining source XML for all versions of legislation since May 2011, rather than only the latest version.
- All metadata is published as RDF Linked Data, is linked to the original legislative sources, and uses standard vocabularies such as the MetaLex Ontology, Dublin Core, Open Provenance Model Vocabulary, Simple Event Model, FOAF, etc.
- All documents and metadata are available through ‘content negotiation': content can be retrieved by using the URI (identifier) of an element as a URL.
- Metadata is accessible through a SPARQL endpoint
- Citations between regulations are made available in a format suitable for social network analysis (Pajek/Gephi)
- A generic conversion script for transforming any legislative XML to CEN MetaLex
For more information, have a look at the presentation on slideshare, or contact Rinke Hoekstra directly.
A report on this work will be published as part of the proceedings of the International Semantic Web Conference (ISWC) 2011: “Rinke Hoekstra. The MetaLex Document Server – Legal Documents as Versioned Linked Data”

On behalf of the Faculty of Law of the University of Amsterdam, the Leibniz Center for Law has entered a collaboration with the Network Institute of the VU University Amsterdam.
“The Network Institute’s research mission is to come to a better scientific understanding of the emerging networked world in all its technological, economic and social aspects, and to help further its proper development.
The Network Institute brings together researchers from many different academic disciplines, including information systems, communication science, computer science, business and management research, knowledge management, marketing and strategy, economics, artificial intelligence, mathematics, and organization science.”
Collaborating with the Network Institute will allow the Leibniz Center to tap into a rich source of likeminded researchers, and at the same time brings the challenges of the field of AI and Law to the attention of a multidisciplinary research network.
For more information, please contact Rinke Hoekstra.

On Thursday May 14 2009 Radboud Winkels and Emile de Maat of the Leibniz Center for Law will give a lecture for the Amsterdam Circle for Law and Language with the title: From Legal Language to Computer Language (Van Juridische Taal naar Computertaal).
The Leibniz Center for Law develops computer models of statutes as well as methods by which the ‘translation’ from legal language to computer language may become automated. A trustworthy, neutral interpretation of the legal text, without added details, is of great importance. In the presentation the speakers will explain these ‘translation’-methods and their ‘technical’ approach to legal interpretation with examples from various areas of law.

The TRIAS Telematica project, coordinated by the Leibniz Center for Law, has been selected as one of the five best e-Learning practices in Europe. The methods used to arrive at this conclusion were a combination of desk research, reports and project conclusions deriving from five years, thematic discussions and the validation of conclusions and recommendations in two thematic seminars in Sofia and Copenhagen.
The aims of TRIAS Telematica are to identify the training needs of change agents, process innovators in government agencies who request rethinking of eGovernment services and to create an infrastructure for the exchange of best practices, the exchange of project leaders and students, and the exchange of qualified people among European countries.
For this purpose an e-Learning environment was developed using semantic wiki and various training methods including a simulation game.
A successor project is being planned as well as a second summer course.
For more information on the project see: http://www.triastelematica.org/

We are pleased to announce the release of the LKIF core ontology of basic legal concepts. This ontology was developed within the ESTRELLA project to provide a standard vocabulary for legal reasoning services on the Semantic Web, and especially the Legal Knowledge Interchange Format (LKIF).
The LKIF ontology is inspired by the commonsense orientation of the (discontinued) LRI Core ontology effort. It consists of 14 ontology modules, describing concepts that range from general concepst such as time, place, change and process to the concepts most central to the legal field such as actions, transactions, beliefs, intentions, expressions and norms.
For more information, please consult the LKIF Core ontology website, browse the online documentation, or download the ESTRELLA Deliverable 1.4.
The ontology can be loaded directly into your favorite OWL Ontology editor from: http://www.estrellaproject.org/lkif-core/lkif-core.owl

Legal Atlas is a tool for viewing both spatial regulations and the associated geospatial information in the form of maps. It is a showcase of how MetaLex integration with existing standards, such as GML and OWL, can result in robust and feature-rich knowledge management solutions. Please read the included license.
Legal Atlas is being developed within the project Digitale Uitwisseling Ruimtelijke Plannen (DURP; digital exchange of spatial plans), initiated by the Dutch government. Legal Atlas enables dynamic references between spatial regulations (encoded in MetaLex v1.3.1 format) and the associated geospatial information. This information is encoded using IMRO2006, the Dutch government standard for XML exchange of spatial plans. It is compatible with GML 3.1.
References between texts and plans are resolved via SPARQL queries on OWL models of both the regulation and the relevant geospatial information.
