Linking Information Needs: Enhancing Crowdsourcing Action through New Media and Online Documentation in Crisis Situations

During crises, social media has emerged as a crucial platform for the dissemination of crisis information; however, it also presents challenges such as information overload, demand matching, and rapid processing. This study focuses specifically on the Henan rainstorm rescue case to analyze the information requirements and dissemination behavior of governmental bodies, social organizations, and netizens. Additionally, it applies crowdsourcing theory to examine bystander behavior during such crises. The findings reveal that bystanders publish a significantly greater number of microblogs compared to government entities and other rescue organizations. Furthermore, online documents play an indispensable role in promoting multi-party participation by leveraging cloud computing technology. Consequently, this enhances crisis management efficiency by mobilizing netizens and the general public to actively engage in crisis information governance.
