Abstract:

After the occurrence of emergencies, coexistence of multiple risk points appears in public opinion communication, which amplifies irrational emotions of the public and causes negative impacts on the ecology of public opinions. In this context, how to accurately predict possible public opinion risk points derived from emergencies in the first time after the occurrence of emergencies has become a targeted and efficient key. In this thesis, based on historical data of emergencies that took place in recent ten years in China, various risk points in the public opinion communication of emergencies are identified and a co-occurrence analysis on risk points is conducted. Secondly, feature similarity algorithm is utilized to calculate the similarity between different emergencies, while Jaccard index is used to quantitatively predict all the explicit and potential public opinion risk points in emergencies. By taking history as a mirror, this research aims to predict public opinion risk points in the budding stage of risks from the perspective of source governance of public opinion risks, with the hope of offering help for grasping the initiative and the right to speak when coping with public opinion risks.

Key words: emergencies, risk points, jaccard index, feature Similarity algorithm, prediction
