(JURISIN 2025)
associated with JSAI International Symposia on AI 2025 (IsAI-2025)


May 26 and 27, 2025

Osaka International Convention Cnter, Osaka, Japan (Hybrid Format)

New Information

We are happy to announce that Springer Verlag has agreed on publication of proceedings of IsAI2025 (including JURISIN 2025 proceedings) as LNAI!!

Aims and Scope

Juris-informatics studies legal issues from the perspective of informatics and AI. The purpose of this workshop is to discuss both the fundamental and practical issues among people from the various backgrounds such as law, social science, information and intelligent technology, logic and philosophy, including the conventional "AI and law" area. We solicit unpublished papers on theories, technologies and applications on juris-informatics.

Invited Speakers

Kenji Suzuki, Institute of Science Tokyo/Sony Group Corporation, Japan
Title: Legal Role of Machine Unlearning in Data Protection Law
Abstract:
This talk explores the potential and limitations of machine unlearning in the context of data protection laws. Machine unlearning refers to a set of techniques that enable the efficient removal of specific data from trained AI models. As concerns over data privacy grow, such techniques are increasingly important for compliance with legal frameworks. While the EU General Data Protection Regulation (GDPR) explicitly guarantees the "right to be forgotten," data protection regimes in other jurisdictions, including the United States, India, and Japan, differ significantly. This presentation analyzes the legal compatibility of machine unlearning across these regions and assesses its practical applicability. The findings suggest that, as machine unlearning technologies continue to evolve, the development of legal guidelines and legislative support will be crucial to realizing their full potential in safeguarding individual privacy.

Georg Borges, Universität; des Saarlandes, Germany
Title: The EU AI Act: A Foundation or Challenge for AI Development?
Abstract:
The European AI Act, adopted in August 2024, is poised to significantly impact developers and users of AI models and systems. With its broad extraterritorial scope, the Act is expected to have a near-global reach. Additionally, many national legislators are already considering similar legislation. For instance, South Korea recently enacted legislation modelled after the EU’s approach.
This presentation will outline the key elements and characteristics of the European AI Act, explore its implications for developers outside the EU, and evaluate its suitability as a blueprint for AI regulation in other jurisdictions.
