  • Title
    Predicting Resilience: AI-enhanced approaches for adaptive policymaking
    Summary
    Governments struggle to manage today"s complex global challenges. The ADAPT project leverages artificial intelligence (AI) to
    identify the governance traits that enable advanced democracies to withstand and recover from crises. This research programme
    develops insights into how well-designed institutions can help societies manage uncertainties.
    ADAPT is structured around constructing three core benchmarks:
    1) The ADAPT Database"an extensive archive of structured and unstructured data documenting resilience across 23 jurisdictions in
    15 languages over 70 years;
    2) A dynamic, multilingual NLP model that extracts adaptive features from legal texts; and
    3) A Resilience Governance Measure designed to predict countries" capacity to resist and react to crises.
    The ADAPT Database integrates economic metrics, legal texts, legislative records, and governance documents, setting a new standard
    in resilient governance research. Using an iterative approach, broadly known as Theory-Guided Artificial Intelligence (TGAI)"which
    combines theoretical frameworks with data-driven methods"ADAPT refines adaptive policymaking models by linking theory with
    practical data-driven applications. Through advanced NLP and machine learning (ML) techniques, including deep learning, ADAPT"s
    dynamic, multilingual model classifies laws and regulations, developing resilience measures that reflect a nation"s ability to respond
    to economic, social, and environmental crises.
    ADAPT reimagines democratic resilience by integrating AI methods with theories of adaptive policymaking. The synergistic results of
    ADAPT's diverse team of experts will catalyze a new wave of scholarship, setting a standard for interdisciplinary research at the nexus
    of AI and public policy. Its scalable and flexible framework provides policymakers and researchers with actionable policy insights and
    tools, crafting systematic responses to crises and strengthening governance in an uncertain world.

  • Title
    Democratic Resilience in the Digital Era (DRIDE)
    Summary
    Democratic Resilience in the Digital Era (DRIDE) will deliver a Horizon Europe Cluster 2 project that supports the call"s objective to reinvigorate and shield European democracy. DRIDE makes democratic resilience measurable, comparable, and actionable by combining comparative governance theory with interpretable, theory-guided analytical methods, including AI, applied to legal and regulatory frameworks. The project analyses how institutional rules, procedures, and governance arrangements shape accountability, transparency, trust, and inclusive participation under conditions of crisis, digital disruption, and external pressure.

    DRIDE develops a policy-focused Institutional Resilience Scorecard and decision-support tools to assist
    democratic actors to:
    " Assess governance features that enhance resilience or expose systems to rigidity and legitimacy risks.
    " Identify accountability gaps and decision-making bottlenecks that arise during crises.
    " Compare the design and robustness of democratic safeguards across countries and sectors to inform
    evidence-based reforms and policy design.
    DRIDE provides policy-making bodies and civil society with interpretable evidence to navigate core democratic trade-offs, including speed versus oversight, discretion versus accountability, and flexible response versus participation. The Resilience Scorecard is designed for practical use by policy
    institutions and civil society, enabling benchmarking and stress-testing of governance frameworks to support evidence-based policymaking. The project delivers reusable outputs that promote EU-wide learning and enable structured comparisons across institutional contexts, time periods, and policy domains.

  • Title
    Competition and Regulation of Technology (CORETEXT)
    Summary
    Technological developments are central to understanding rapid changes in power structures in society, as market power is augmented by data and by hardware and software technologies (such as platforms and search) that are controlled by a few players. Efforts to address power and ensure that new companies can succeed without hindrance rely on a combination of regulation and competition. Meanwhile, European success in creating durable technical enterprises has been limited, posing enduring questions about how to succeed in the economy of the future. The CORETEXT Doctoral Networks (DN) will train the next generation of scientists in a range of interdisciplinary and cross-sector methods to make significant progress in understanding how to regulate existing companies and motivate new ones. Training is structured around two interdisciplinary research themes: Understanding: analysis, theories of societal risks, harm, and benefits, and remedies, and Application: law and governance. Both involve extensive, systematic co-supervision and collaboration across sites, with vigorous interplay between academic beneficiaries and associated partners. In turn, we expect improved governance and laws to emerge, with associated societal and economic benefits. The training of the cohort of Doctoral Candidate (DC) fellows is based on innovative PhD training approaches, providing not only interdisciplinary training but also peer-assisted methods and in-depth work-based expertise. This will produce a cohort of highly skilled researchers who will be highly employable, given the potential contribution they will make to future research and innovation in the public and private sectors.
