Crisis Information Release Policy and Online Public Opinion Dissemination in Emergency of Hazardous Chemicals Leakage into River:A Multi-agent-based Model

Abstract

Abstract:

This paper develops a multi-agent-based simulation model for online public opinion dissemination in emergency, to explore appropriate crisis information release policy for controlling public panic stemming from hazardous chemicals leakage accidents into rivers. In particular, two attributes of the crisis information are considered, i.e., the truthiness (true or false news) and attitude (neural, positive or negative emotion). Moreover, the proposed model covers the main agents in virtue community:the citizens, government, and media. We take two typical accidents of hazardous chemicals leakage into rivers as study cases, to test the feasibility and effectiveness of the model.

Key words: crisis information, public panic, online opinion dissemination, hazardous chemicals leakage, multi-agent-based model
