Abstract: Legal claims refer to the plaintiff's demands in a case and are essential to
guiding judicial reasoning and case resolution. While many works have focused
on improving the efficiency of legal professionals, the research on helping
non-professionals (e.g., plaintiffs) remains unexplored. This paper explores
the problem of legal claim generation based on the given case's facts. First,
we construct ClaimGen-CN, the first dataset for Chinese legal claim generation
task, from various real-world legal disputes. Additionally, we design an
evaluation metric tailored for assessing the generated claims, which
encompasses two essential dimensions: factuality and clarity. Building on this,
we conduct a comprehensive zero-shot evaluation of state-of-the-art general and
legal-domain large language models. Our findings highlight the limitations of
the current models in factual precision and expressive clarity, pointing to the
need for more targeted development in this domain. To encourage further
exploration of this important task, we will make the dataset publicly
available.
