This lecture delves into the analysis of postmortem memory of public figures in news and social media, exploring the processes by which groups and societies remember and forget. The instructor presents a research paper highlighting the collective memory phenomenon, the role of media in memory construction, and the impact of social media on memory formation. The lecture covers the detection of names in a large corpus of data, the visualization of postmortem memory curves, and the biographic correlates of memory patterns. Through regression analysis, the lecture uncovers significant insights into how different factors influence the postmortem memory of public figures.
