AI4J – Artificial Intelligence for Justice AI4J { Artificial Intelligence for Justice August 30, 2016 The Hague, The Netherlands Workshop at the 22nd European Conference on Artificial Intelligence (ECAI 2016) Workshop chairs Floris Bex Department of Information and Computing Sciences, Utrecht University Tom van Engers Leibniz Center for Law, Faculty of Law, University of Amsterdam Henry Prakken Faculty of Law, University of Groningen; Department of Information and Computing Sciences, Utrecht University Bart Verheij Institute of Artificial Intelligence and Cognitive Engineering, University of Groningen Artificial intelligence is currently in the centre of attention of legal professionals. An abundance of startup companies explore the application of AI techniques in the domain of law, and there is even talk of artificially intelligent legal assistants disrupting the legal market space. Factors driving the increased attention for legal AI include: Technological breakthroughs in machine learning, natural language process- ing, ubiquitous computing, data science, and argumentation technology; The changing attitude towards technology in the legal domain; The much increased availability of legal data on the internet; The recent success of AI applications in the private and public domain; The success of technology supporting access to law, legal empowerment, and transparency; The increased need for norms embedded in technology (autonomous driving and warfare, big data analysis for crime fighting and counterterrorism). The aim of this workshop is to investigate opportunities and challenges in AI ap- plied to the law, with a particular focus on the relevance of the recent technological breakthroughs for AI & Law research and for legal practice. Questions addressed include the following: How can AI & Law research contribute to improving legal work in, for exam- ple, courts, law firms, public administration, police practice and businesses? How should AI & Law research change in light of the recent research break- throughs and technological developments? For example, how can traditional research on legal knowledge bases, legal reasoning and legal argument be combined with data science, machine learning and natural language pro- cessing? The law has been a longstanding application field for AI research. The biennial International conferences on AI & Law (ICAIL) started in 1987, the annual JURIX conferences on Legal Knowledge and Information Systems in 1988, and the journal Artificial Intelligence and Law was founded in 1992. Many ideas that are currently being commercially developed were first explored by AI & Law researchers, such as legal information retrieval, statistical analysis of legal data, automated con- tract drafting, automated processing of permit or welfare applications in public administration, and systems for regulatory compliance. Some particular topics of relevance to the focus of the workshop are: Open data, linked data, big data; e-Discovery; Legal argument mining; Automated contract drafting; Computable contracts; Decision support for legal, forensic and police practice; Computational law.

  • Measuring, Monitoring, and Managing Legal Complexity
    A5_RUHL&KATZ.DOCX (DO NOT DELETE) 10/16/2015 8:55 AM Measuring, Monitoring, and Managing Legal Complexity J.B. Ruhl & Daniel Martin Katz ABSTRACT: The American legal system is often accused of being “too complex.” For example, most Americans believe the Tax Code is too complex. But what does that mean, and how would one prove the Tax Code is too complex? Both the descriptive claim that an element of law is complex and the normative claim that it is too complex should be empirically testable hypotheses. Yet, in fact, very little is known about how to measure legal complexity, much less how to monitor and manage it. Legal scholars have begun to employ the science of complex adaptive systems, also known as complexity science, to probe these kinds of descriptive and normative questions about the legal system. This body of work has focused primarily on developing theories of legal complexity and positing reasons for, and ways of, managing it. Legal scholars thus have skipped the hard part— developing quantitative metrics and methods for measuring and monitoring law’s complexity. But the theory of legal complexity will remain stuck in theory until it moves to the empirical phase of study. Thinking about ways of managing legal complexity is pointless if there is no yardstick for deciding how complex the law should be. In short, the theory of legal complexity cannot be put to work without more robust empirical tools for identifying and tracking complexity in legal systems. This Article explores legal complexity at a depth not previously undertaken in legal scholarship.

  • A Philosophy of Technology for Computational Law
    © Mireille Hildebrandt, draft chapter for OUP’s The Philosophical Foundations of Information Technology Law, eds. David Mangan, Catherine Easton, Daithí Mac Síthigh A philosophy of technology for computational law Abstract: This chapter confronts the foundational challenges posed to legal theory and legal philosophy by the surge of computational law. Two types of computational law are at stake. On the one hand we have artificial intelligence in the legal realm that will be addressed as data-driven law, and on the other hand we have the coding of self-executing contracts and regulation in the blockchain, as well as other types of automated decision making (ADM), addressed as code-driven law. Data-driven law raises problems due to its autonomic operations and the ensuing opacity of its reasoning. Code-driven law presents us with a conflation of regulation, execution and adjudication. Though such implications are very different, both types of computational law share assumptions based on the calculability and computability of legal practice and legal research. Facing the assumptions and implications of data- and code-driven law the chapter will first investigate the affordances of current, text-driven law, and relate some of the core tenets of the Rule of Law to those affordances. This will lead to an enquiry into what computational law affords in terms of legal protection, assuming that one of the core functions of the law and the Rule of Law is to protect what is not computable. Keywords: positive law, rule of law, legal certainty, justice,

  • Text and Data Mining in Intellectual Property Law: Towards an Autonomous Classification of Computational Legal Methods 1
    TEXTAND TEXT AND DATA DATAMINIMINING IN INTELLECTUAL NGININTELPROPERTY LAW TOWARDS AN AUTONOMOUS CLASSIFICATION OF LECTUALPCOMPUTATIONAL LEGAL METHODS ROPERTYLCREATe Working Paper 2020/1 AWTOWATHOMAS MARGONI RDSANAU T Text and Data Mining in Intellectual Property Law: Towards an Autonomous Classification of Computational Legal Methods 1 Thomas Margoni2 I. Introduction Text and Data Mining (TDM) can generally be defined as the “process of deriving high-quality information from text and data,”3 and as a “tool for harnessing the power of structured and unstructured content and data, by analysing them at multiple levels and in several dimensions in order to discover hidden and new knowledge.”4 In other words, TDM refers to a set of automated analytical tools and methods that have the goal of extracting new, often hidden, knowledge from existing information, such as textual information (text mining) or structured and unstructured data (data mining), and on this basis annotate, index, classify and visualise such knowledge. All this, which is made possible by the fast advancements in computational power, internet speed, and data availability has the potential to constitute, if not a revolution in the scientific field, certainly a major advancement in the speed of scientific development as well as in its direction. In particular, the impact that TDM may have in the direction of scientific enquiry is invaluable. This is because by identifying the correlations and patterns that are often concealed to the eye of a human observer due to the amount, complexity, or variety of data surveyed, TDM allows for the discovery of concepts or the formulation of correlations that would have otherwise remained concealed or undiscovered.

  • Bottleneck Or Crossroad? Problems of Legal Sources Annotation and Some Theoretical Thoughts
    Article Bottleneck or Crossroad? Problems of Legal Sources Annotation and Some Theoretical Thoughts Amedeo Santosuosso * and Giulia Pinotti Research Center ECLT, University of Pavia, 27100 Pavia PV, Italy; [email protected] * Correspondence: [email protected] Received: 30 July 2020; Accepted: 6 September 2020; Published: 9 September 2020 Abstract: So far, in the application of legal analytics to legal sources, the substantive legal knowledge employed by computational models has had to be extracted manually from legal sources. This is the bottleneck, described in the literature. The paper is an exploration of this obstacle, with a focus on quantitative legal prediction. The authors review the most important studies about quantitative legal prediction published in recent years and systematize the issue by dividing them in text-based approaches, metadata-based approaches, and mixed approaches to prediction. Then, they focus on the main theoretical issues, such as the relationship between legal prediction and certainty of law, isomorphism, the interaction between textual sources, information, representation, and models. The metaphor of a crossroad shows a descriptive utility both for the aspects inside the bottleneck and, surprisingly, for the wider scenario. In order to have an impact on the legal profession, the test bench for legal quantitative prediction is the analysis of case law from the lower courts. Finally, the authors outline a possible development in the Artificial Intelligence (henceforth AI) applied to ordinary judicial activity, in general and especially in Italy, stressing the opportunity the huge amount of data accumulated before lower courts in the online trials offers. Keywords: legal sources; prediction; legal analytics 1.

  • Science and Technology Law Review
    The Columbia SCIENCE AND TECHNOLOGY LAW REVIEW www.stlr.org THE VARIABLE DETERMINACY THESIS Harry Surden1 This Article proposes a novel technique for characterizing the relative determinacy of legal decision-making. I begin with the observation that the determinacy of legal outcomes varies from context to context within the law. To augment this intuition, I develop a theoretical model of determinate legal decision-making. This model aims to capture the essential features that are typically associated with the concept of legal determinacy. I then argue that we can use such an idealized model as a standard for expressing the relative determinacy or indeterminacy of decision-making in actual, observed legal contexts. From a legal theory standpoint, this approach – separating determinacy and indeterminacy into their constituent conceptual elements – helps us to more rigorously define these theoretical ideas. Ultimately, from a practical standpoint, I assert that this framework assists in understanding why legal outcomes in certain contexts are determinate enough to be amenable to resolution by computers. 1 Associate Professor, University of Colorado Law School.

Data mining, machine learning, simulations and other computational methods lie today at the hearth of the scientific endeavour in a growing number of social research areas from anthropology to economics. In this scenario, an increasingly important role is played by analytical platforms: integrated environments allowing researchers to experiment cutting-edge data-driven and computation-intensive analyses. The paper discusses the appearance of such tools in the emerging field of computational legal science. After a general introduction to the impact of computational methods on both natural and social sciences, we describe the concept and the features of an analytical platform exploring innovative cross-methodological approaches to the academic and investigative study of crime.
