The EXplainable & Responsible AI in Law (XAILA) Workshop

The main XAILA webpage is http://xaila.geist.re

XAILA is an interdisciplinary workshop on the intersection of AI and Law, focusing on the important issues of EXplainable and Responsible AI.

In 2021 we are planning next editions of XAILA.

See more information on the past editions of XAILA.

The 4th International Workshop on eXplainable and Responsible AI and Law (XAILA2021@ICAIL) at the 18th International Conference on Artificial Intelligence and Law (ICAIL 2021) held in Sao Paulo, Brazil (entirely online), Date: 21 June 2021

The idea of the XAILA series of JURIX workshops (1st edition XAILA 2018 in Groningen, 2nd edition XAILA 2019 in Madrid, 3rd edition XAILA 2020 in Brno (online)) is to provide an interdisciplinary platform for the discussion of ideas with respect to explainable AI, algorithmic transparency, comprehensiveness, interpretability and related topics. This year’s edition is particularly focused on the emerging idea of responsible AI (RAI) and multiple connections between the notions of explainability and responsibility but we also aim to continue the discussion in the scope of all domains related to the workshop’s topic.

In the last several years we have observed a growing interest in advanced AI systems achieving impressive task performance. However, there has also been an increased awareness of their complexity and challenging consequences of their possibly limited understandability to humans. In response, a number of research directions have been initiated. These include humanized or human-centered AI, as well as ethically aligned, ethically designed, or just ethical AI. For many of these ideas, the principal concept seems to be the explanatory capability of the AI system (XAI), e.g. via interpretable and explainable machine learning, inclusion of human background knowledge and adequate declarative knowledge, that could provide foundations not only for transparency and understandability, but also for a possible value alignment and human centricity, as the explanation is to be provided to humans.

Recently, the term responsible AI (RAI) has been coined as a step beyond XAI. Discussion of RAI has been again strongly influenced by the “ethical” perspective. However, as practitioners in our fields we are convinced that the advancements of AI are way too fast, and the ethical perspective much too vague to offer conclusive and constructive results. We are convinced that the concepts of responsibility, and accountability should be considered primarily from the legal perspective, also because the operation of AI-based systems poses actual challenges to rights and freedoms of individuals. In the field of law, these concepts should obtain some well-defined interpretation, and reasoning procedures based on them should be clarified. The introduction of AI systems into the public, as well as the legal domain brings many challenges that have to be addressed. The catalogue of these problems include, but is not limited to: (1) the type of liability adequate for the operation of AI (be it civil, administrative of criminal liability); (2) the (re)interpretation of classical legal concepts concerning the ascription of liability, such as causal link, fault or foreseeability and (3) the distribution of liability among the involved actors (AI developers, vendors, operators, customers etc.). As the notions relevant for the discussion of legal liability evolved on the basis of observation and evaluation of human behavior, they are not easily transferable to the new and disputable domain of liability related to the operation of artificial intelligent systems. The goal of the workshop is to cover and integrate these problems and questions, bridging XAI and RAI by integrating methodological AI, as well as the respective ethical and legal perspectives, also specifically with support of established concepts and methods regarding responsibility, and accountability.

Our objective is to bring people from AI interested in XAI and RAI topics  and create an ample space for discussion with people from the field of legal scholarship and/or legal practice, and most importantly the vibrant AI & Law community. As many members of the AI and Law community join both perspectives, the JURIX conference is the perfect venue for the workshop. Together we would like to address some questions like:

• the notions of transparency, interpretability and explainability in XAI
• non-functional design choices for explainable and transparent AI systems
• legal consequences of black-box AI systems
• legal criteria and requirements for explainable, transparent, and responsible AI systems
• criteria of legal responsibility discussed in the context of intelligent systems operation and the role of explainability in liability ascription
• possible applications of XAI systems in the area of legal policy deliberation, legal practice, teaching and research
• legal implications of the use of AI systems in different spheres of societal life
• the notion of right to explanation
• relation of XAI and RAI to argumentation technologies
• approaches and architectures for XAI and RAI in AI systems
• XAI, RAI and declarative domain knowledge
• risk-based approach to analysis of AI systems and the influence of XAI on risk assessment
• incorporation of ethical values into AI systems, its legal interpretation and consequences
• XAI, privacy and data protection (conceptual and theoretical issues)
• XAI, certification and compliance

Title of the talk AI and Discrimination: Legal Challenges and Technical Strategies

Abstract The talk will focus on the interaction between AI models and liability in the domain of non-discrimination. As is well-known, the output of AI models may exhibit bias toward legally protected groups. In the past, various fairness definitions have been developed to mitigate such discrimination. Against this background, the talk will first present a new model which allows AI developers to flexibly interpolate between different fairness definitions depending on the context of the model application. In the second step, however, the talk will inquire to what extent AI developers may risk liability under affirmative action doctrines if they seek to implement algorithmic fairness measures in their models.

Reinoud Baker

Title Legal information systems in production

Abstract LexIQ is a Dutch legal tech startup using data science for legal information services. We have the vision that legal tech can serve citizens, governments and businesses, for instance by improved access to justice, efficient use of resources and enhanced compliance. This talk will address what we have learned in the past 4 years. What can be achieved with modern software and algorithms? How can we make innovative technologies available for legal professionals and even the wider public? Which challenges are we encountering?
