UvA LogoWelcome 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 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, application of data science and machine learning techniques in the field of law, and the application of information technology in education and legal practice. As an academic partner, the Leibniz Center provides advice on change management in legal-knowledge-intensive processes and on improvement of legal knowledge productivity in organisations.

The Leibniz Center for Law has its roots in the former department of Computer Science & Law (est. 1989) of the Faculty of Law of the University of Amsterdam.

For more background on the Leibniz Center, see our general information pages, and have a look at current projects. Students interested in our work may look for our proposals for Bachelor/Master theses.

New NWO grant cooperations with the Informatics Institute

The University of Amsterdam’s Systems and Network Engineering Lab at the Informatics Institute, with assistance of the Leibniz Center for Law, have recently been awarded several new grants from the Netherlands Organisation for Scientific Research (NWO). The Leibniz Center and SNE already cooperate in the long-running SARNET project (1 PhD student and 1 Post-doc) on Internet Security. The projects will take place within the Informatics Institute, but with personnel involvement of the Leibniz Center for Law.

A round-up of the new NWO grants:

DL4LD or Data Logistics for Logistics Data: The proposed research (2 PhD students, 1 Post-doc) focuses on 1) the design and implementation of capabilities that are required for creating value-rich logistic information services and 2) creation of innovative solutions that allow stakeholders to agree on how data is stored, accessed, shared and transformed in a controllable, enforceable, accountable, auditable and goal-oriented fashion.

Secure Scalable Policy-Enforced Distributed Data Processing: The project (1 PhD student) combines big data, high performance computing and cryptology in multidisciplinary fundamental and applied research. The project aims to develop integrated secure, end-to-end trusted, scalable and future-proof solutions for the problem of policy-enforced distributed data sharing and processing across multiple logistic domains. This NWO ‘Big Data: Real Time ICT for Logistics’ grant is part of the Commit2Data initiative, a national public-private research-and innovation programme intended to to keep and strengthen the Dutch top 5 position in Big Data.

Distributed FAIR information systems to enable federated learning and reasoning: The project (1 Post-doc) aims to find solutions for constructing FAIR (Findable Accessible Interoperable Reusable) data services that allow competing organizations to share & analyse data for a common and agreed goal but not for any other purposes.

Leibniz Center has moved to a new location

During the summer holidays, the Leibniz Center for Law moved, together with the rest of the Faculty of Law, to a new location in the Roeterseiland campus of the University of Amsterdam. This means that we have a new visiting address:

Roeterseilandcampus, building A, 6th floor
Nieuwe Achtergracht 166
1018 WV Amsterdam
The Netherlands

The address for mail (not packages) has not changed.

As many visitors have noticed, the move of our servers was far from flawless, resulting in significant downtime of this, and other, websites.

Two PhD positions in Cyber-security (Computer Science)

The Netherlands Organization for Scientific Research (NWO) has funded a project to detail and validate a new concept for the autonomous control of networking and computing facilities to maximize the cyber security of their users. Here control software interacts with programmable network and cloud resources to change the logical or physical topology of the network and a part of the Internet. Similarly the control software interacts with cyber-security software to switch on or off firewalls, honeypots and other cyber- security services. Furthermore the control software adapts the distributed application (payload) itself. Such interactions must lead to a reliable, trusted, and obfuscated distributed system that actively maximizes its cyber-security state. When an incident occurs it is essential to get the right support as soon as possible. From explaining the business impact of an incident to conducting detailed technical analysis, sapphire.net and their team can assist during the critical phases of an investigation. The websites built with the ultimate experience of the top web design companies that will help you stay at the top of search results and security as well as it will also help you update the instances regularly.

The research project funds two PhD candidates. Their research yields the science 1) to specify the cyber security state of an information processing system, to visualize and characterize that as well as 2) the science to compute and implement interventions that sets the cyber security stated to a desired one.

The PhD research is done in the context of Air France/KLM, CIENA Networks and TNO that provide data centre, telecom and internet technologies to validate the results and the business context for their dissemination. UvA and TNO provide labs and supervise the research.


The candidates should have completed a master in computer science, or will acquire that on short notice and originate from the EU or USA. A ‘Certificate of Conduct for Natural Persons (VOG NP)’ may be requested by the partners. On a master’s level, the candidates must have knowledge of information theory and mathematics and strong coding abilities. Knowledge of networks, cyber security and distributed systems is considered as a pre. The candidates will stay short periods abroad, must have the ability to give demonstrations to scientific and business audiences. Their grades list demonstrate of their knowledge and ambition, their master thesis of their ability to continue with a PhD research in Computer Science.

SARNET: NWO grant for Internet Security

The University of Amsterdam has been awarded a grant from the Netherlands Organisation for Scientific Research (NWO) for the Security Autonomous Response NETworks project (SARNET). This project falls under the NWO Cyber Security programme, which seeks to increase the security of our digital society while at the same time addressing privacy concerns.

This theft lawyer explores what is needed to provide an autonomous means of Internet security at the supra-company level. The research employs software-defined networking technology, with Internet provider networks and company networks working together on detection and defence. An endpoint detection and response security solution means companies will be no longer be alone in their fight against cybercrime. When an attack is detected by a provider and/or company, protection will also be programmed at other companies and providers. This information technology allows SARNET to be jointly managed by Internet service providers and specialised companies.Make sure you have experts that can detect cloud configuration errors and keep hackers away.

The research is being conducted at the UvA, in the Informatics Institute, and involving the Leibniz Center for Law, while the Netherlands Organisation for Applied Scientific Research (TNO) and network manufacturer Ciena are working to put it into practice at Air France-KLM.

The SARNET grant is €680,000, of which €400,000 is funded by the NWO and the remainder by industrial partners KLM, CIENA and TNO.

Key assessment criteria were the scientific quality of the research proposal, the knowledge utilisation factor and the relevance of the research to the National Cyber Security Strategy (NCSRA-II). The NCSRA-II is part of the IT Roadmap of the government’s Top Sectors policy.

This research programme is part of the second investment round of the cyber security study. Financiers and initiators are the ministries of the Interior & Kingdom Relations, Defence, Economic Affairs, Finance, Infrastructure & the Environment and Security & Justice (coordinated by the Ministry of Economic Affairs), the Governing Board of the NWO and the NWO areas of Exact Sciences (EW), Social and Behavioural Sciences (MaGW), and the STW technology foundation.

All Dutch Legislation published as CEN MetaLex and Linked Open Data

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”

Lecture for the Amsterdam Circle for Law and Language

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.

TRIAS Telematica awarded best practice on e-Learning in Europe

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 with the help of Skill Success, 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.

LKIF Core Ontology

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
