- W2373783981 abstract "An emergency can lead to the crisis of social emotion.Therefore,it is very critical for emergency agencies to monitor and manage public negative emotion during an emergency.Based on the aging theory,this paper proposes a public negative emotion model to monitor and manage emergencies to minimize the negative impact of emotional crisis on a society.By detecting microblog topics and analyzing microblog sentiment,this paper builds a warning framework to manage public negative emotion based on the negative emotion model. In the first part,we introducethe aging theory model and discuss its effectiveness.The evolution of the public negative emotion during two emergency events show that the aging theory is fit for modeling the public negative emotion.Next,we build a public negative emotion model based on the aging theory model,and describe the design of nutrition and energy functions. In the second part,this paper builds a public negative emotion warning framework based on the negative emotion model.This framework is comprised of four parts: topic detection and tracking,sentiment analysis,emotion status analysis,and negative emotion warning.According to the characteristics of a microblog,we design a novel TDT algorithm and a Chinese emotion analysis algorithm.In addition,we calculate negative emotional status and discuss how to conduct the emotion warning. In the third part,the model is verified throughanalyzing 25 emergency events.The experimental results show that the model is effective,and it can correctly reflect the development of public negative emotion in a timely manner.We also discuss the advantages of the HMM-based model. Insummary,it is very important to analyze and monitor the public negative emotion during emergency events.Our proposed model can aid emergency agencies in improving the effectiveness of emergency management." @default.
