A Method to Extract Causality for Safety Events in Chemical Accidents from Fault Trees and Accident Reports

Abstract: Chemical event evolutionary graph (CEEG) is an effective tool to perform safety analysis, early warning, and emergency disposal for chemical accidents. However, it is a complicated work to find causality among events in a CEEG. This paper presents a method to accurately extract event causality by using a neural network and structural analysis. First, we identify the events and their component elements from fault trees by natural language processing technology. Then, causality in accident events is divided into… Show more

“…A higher speed limit leads riders to fail to give way when turning [3]. A long waiting time at red lights [23], low density of motorized vehicles [24], and riding at the peak of morning [25] are in correlation with disobeying traffic signals. Among human factors except behavior, male riders and young riders are more likely to commit dangerous behaviors.…”
