Abstract

Considering the relationship between the experts and the decision risk caused by the fuzziness of the expert preference information under the social network, a research method for the risk measurement of the large flood disaster emergency decision in the social network is proposed. First, we use large data technology to extract key words, then use TF-IDF technology to process large data, extract public concern and determine attribute weight. Secondly, the relationship between experts is taken into consideration in decision making, social network relationship of decision experts is constructed based on social network technology and expert decision is combined. The decision risk is measured by the policy preference. Finally, through the relative score, the final group decision plan is obtained.
