Innovative data science methodologies offer new and exciting possibilities to study the legal system’s behaviour, gain new possibilities to enhance the quality of legal decision-making and gives new insights into the complex interaction between legal actors.

Amongst others, the legal system can be observed as an enormous information processing system. The design of laws and regulations, court procedures and governmental enforcement activities are all based on and produce data and data products. Data processing and analysis techniques have been supporting legal practice and the execution of laws and regulations by governmental agencies for a long time.

Driven by current ICT innovation, data science techniques and experts in swift pace become the core of legal value and knowledge creation processes. Intelligent processing of large amounts of legal documents enhances the quality of legal advice and judgments. Machine learning based applications for instance, are already being used to predict court decisions, and governmental organisations like tax administrations enrol data science departments in order to improve their inspection’s hit rates.

Building computational models of (parts and aspects of) the legal system supports new ways of scientific legal research as well. New questions can be formulated and new and surprising insights gained. This scientific approach will focus on the system level rather than a case level. Examples of this system’s perspective are the measurement and assessment of the impact of legal decisions and scholarly comments, the interaction between legal systems over time, or the design and analysis of the behaviour of (actors within) legal systems from a network perspective.  

We are just beginning to discover the great opportunities offered by this data science perspective for the innovation of legal research.

Measuring relevance and relations of Dutch legal publications

Gineke Wiggers

Legal scholars and professionals are confronted with a rapidly increasing volume of legal publications.

The international tax system as a complex system

Manon Wintgens

The international tax system is composed of multiple layers, i.e., law and regulations,  jurisdictions, and businesses. Previously, these inherently different layers were often analysed from a fiscal perspective. In contrast, this data-driven research project aims to study the international tax system in its entirety from a complex systems perspective.
