Outline
To enhance the scientific nature and effectiveness of online emergency language services, based on Hovland's persuasion theory, it identified the factors influencing the effectiveness of online emergency language services, clarified the input and output indicators for evaluating emergency language services, constructed an evaluation system for the effectiveness of online emergency language services during the emergency response phase, and established an evaluation process for the effectiveness of emergency language services. Taking the 6·21 Yinchuan Barbecue Shop Explosion Accident as an example, big data analysis was conducted on the information released by official media on the Weibo platform during the emergency response phase. Five types of media accounts were identified as decision-making units (DMU): emergency (including firefighting) media, public prosecution and law enforcement media, central-level mainstream media, other government media, and local-level media. The date envelopment analysis(DEA) method was employed to evaluate the effectiveness of emergency language services. The results of this study illustrated that the effectiveness of online emergency language service is from high to low for the central-level mainstream media, public prosecution and law enforcement media, emergency (include firefighting) media, other government and local-level media. There is a significant gap between other government and local-level media and the top three types of media in terms of emergency language service effectiveness. Further exploration is needed to identify ways to improve the effectiveness of emergency language services for these media types.
