Abstract

Fall-from-height (FFH) accidents remain a major source of workplace injuries and fatalities. Fall protection systems (FPS) are critical for preventing falls in the work-at-height (WAH) environment. However, challenges in designing and selecting effective FPS persist across various industries, and existing tools often lack practical references. This study aims to develop an FFH-specific knowledge graph (FFH-KG) to support FPS design. By structuring accident data, the FFH-KG provides empirical insights to help designers improve FPS frameworks, aiding safety planning and decision-making. It serves as a decision support system for FPS designers and safety professionals, guiding the selection and design of appropriate protection solutions for diverse WAH scenarios. The FFH-KG was constructed using a hybrid natural language processing approach, combining manual extraction, entity recognition, text segmentation, and rule-based relation extraction. It was grounded in a schema layer (i.e., ontology) established by experts. A text-mining approach, integrating machine learning with a large language model, facilitated the categorization of fall types, refinement of WAH scenarios, and identification of fall causes, enhancing the content and applicability of knowledge graph. A total of 2,200 entities and 4,820 relationships were created based on fall protection equipment standard documents and fall-from-height accident investigation reports, forming a foundation for developing countermeasures. The retrieval performance of FFH-KG was validated through three case studies. This research has also made significant progress in intelligent safety engineering and management across industries.
结合机器学习和大型语言模型构建领域知识图,降低坠楼事故风险。
高空坠落事故仍然是工作场所伤害和死亡的主要原因。坠落保护系统(FPS)是防止在高空工作(WAH)环境中坠落的关键。然而,设计和选择有效FPS的挑战在各个行业都存在,而现有工具往往缺乏实际参考。本研究旨在开发ffh特定知识图谱(FFH-KG)来支持FPS设计。通过结构化事故数据,FFH-KG提供了经验见解,帮助设计人员改进FPS框架,帮助安全规划和决策。它作为FPS设计人员和安全专业人员的决策支持系统,指导选择和设计适合各种WAH场景的适当保护解决方案。FFH-KG采用混合自然语言处理方法构建,结合人工提取、实体识别、文本分割和基于规则的关系提取。它以专家建立的模式层(即本体)为基础。文本挖掘方法将机器学习与大型语言模型相结合,促进了跌倒类型的分类、WAH场景的细化和跌倒原因的识别,增强了知识图的内容和适用性。根据坠落防护设备标准文件和坠落事故调查报告,共建立2200个实体和4820个关系,为制定对策奠定了基础。通过三个案例验证了FFH-KG的检索性能。该研究还在智能安全工程和跨行业管理方面取得了重大进展。

期刊介绍: Accident Analysis & Prevention provides wide coverage of the general areas relating to accidental injury and damage, including the pre-injury and immediate post-injury phases. Published papers deal with medical, legal, economic, educational, behavioral, theoretical or empirical aspects of transportation accidents, as well as with accidents at other sites. Selected topics within the scope of the Journal may include: studies of human, environmental and vehicular factors influencing the occurrence, type and severity of accidents and injury; the design, implementation and evaluation of countermeasures; biomechanics of impact and human tolerance limits to injury; modelling and statistical analysis of accident data; policy, planning and decision-making in safety.
