网络事件重提激发视角下的公众记忆效果测度与偏好识别研究

[Purpose/ significance] This study aims to explore how the re-mention of online events in the digital age triggers and shapes public memory, revealing how social media, as a dynamic interactive platform, participates in the reproduction, dissemination, and evolution of memory. This provides a new perspective for understanding the characteristics of collective memory and the mechanisms of information dissemination in the context of re-mentioned online events. [Method/ process] By constructing quantitative indicators of memory intensity, breadth, speed, and preference, computational models were employed to analyze the evolution patterns of public memory under the re-mention of online events. In addition, an in-depth analysis of 384510 social media data points was conducted using actual cases. [Results/ conclusion] Stimulus events significantly triggered public recollection and emotional resonance with the original events, with different types of events affecting memory intensity, breadth, and speed in varying ways. Public memory preferences revealed thematic sensitivity and emotional tendencies in the process of memory reconstruction. Online event re-mention not only promoted the reproduction and communication of memory but also reshaped public cognition and emotion towards past events. The findings further deepen the understanding of the collective memory construction process in the digital age and provide a method for predicting the dynamics of public memory from the perspective of event clusters. Using public memory connections as a clue to capture the intermittent dissemination patterns of online event information; this study offers strategic references for optimizing the emergency management of online event information.
