Abstract: In the real-life uncertain environment, many attribute values of network public sentiment emergency are easily expressed by fuzzy linguistic terms. In this study, we aim to propose the weight assignment method for the selected warning indexes of network sentiment emergency by using extended fuzzy AHP and a new decision-making approach for uncertain network public sentiment emergency is then presented. By means of the information fusion technique of fuzzy warning index values, we can order the severity of each network public sentiment emergency according to the ranking value of the fuzzy aggregation value of each network public sentiment emergency and select the most severe one for emergency decision.
