这篇论文搞了个IUU+DB系统，用LLM自动从大量文档里挖出非法捕捞和海鲜欺诈的线索，能帮监管者和研究人员快速定位热点区域，挺实用的。
论文提出IUU+DB系统，利用大语言模型（LLM）从异构文档中提取非法、未报告和未监管捕捞（IUU）及相关海鲜欺诈、劳工虐待事件信息。系统可分类是否相关，提取行为者、地点、物种、船舶、违规类型及执法结果等关键数据，并支持去重和趋势分析。案例验证表明，IUU+DB能帮助组织碎片化证据，识别地理和行为热点，为学术界、非政府组织、行业风险评估及政府政策执行提供支持。
IUU+DB: Tracking Illegal, Unreported, and Unregulated Fishing, Seafood Fraud, and Labor Abuse through LLM-driven Information Extraction
Illegal, unreported, and unregulated fishing (IUU) traditionally refers to fishing activities that violate applicable laws or occur in areas that lack applicable laws. We propose the term IUU+ to capture a broader suite of fisheries sector environmental and associated supply chain trade-related crimes and behaviors. Although IUU+ activity is widely recognized as a serious threat to marine ecosystems, markets, and livelihoods, a quantitative understanding of these incidents, e.g., their frequency, geography, species, actors, and patterns in the type of illicit activity, remains difficult to obtain. We propose IUU+DB, a large language model driven system for building a global incident database of IUU+ activity. The system ingests heterogeneous documents, classifies whether they describe relevant incidents, extracts key data elements such as actors, locations, species, vessels, violations, and enforcement outcomes, and supports deduplication and trend analysis. Case studies and validation results show that IUU+DB can help organize fragmented evidence, surface geographic and behavioral hotspots, support fisheries-domain specific research in academia and non-government organizations, assist source and species risk assessments for industry, and provide support for policy implementation and targeted enforcement efforts to government agencies.
