Research

The Center works across three connected areas: trustworthy governance, professional services and human–AI interaction. Research examines not only whether AI can complete complex tasks, but also whether its evidence is reliable, its processes can be reviewed, and people can participate in judgment and responsibility.

Trustworthy AI Governance and Compliance

How can legal obligations become auditable requirements and tests?

Regulatory tracking, data governance and AI assurance.

More

AI and High-Stakes Professional Services

How can legal practice advance AI reasoning and verification?

Legal AI evaluation, LexiHK research and accountable professional workflows.

More

Human–AI Interaction and Cross-Disciplinary Impact

How do people judge, rely on and challenge AI?

Studies of professional work, accountability and interdisciplinary education.

Projects & Tools

LexiHK workspace

LexiHK

LexiHK is a home-grown legal AI platform built for Hong Kong’s bilingual common-law setting and developed with the Hong Kong Generative AI Research and Development Centre (HKGAI). It provides legal chat, retrieval, case research, document drafting and contract review, and serves as a testbed for source verification, reliable reasoning and human–AI collaboration. Its product and research operations are presented separately from the Center.

LexAgentHallu

Forthcoming · EMNLP 2026 · Preprint available

LexAgentHallu evaluates hallucinations across the multi-step trajectories of legal agents. Its hierarchical taxonomy distinguishes legal-content errors from failures in tool use and agent procedures, helping researchers locate problems that final-answer scores can overlook.
