“…Of these 30, after reading the abstracts, 7 would have been included in our Database, but only one actually was included. Examples of those not included are "Rapid flood inundation mapping using social media, remote sensing and topographic data" (Rosser et al, 2017), "Sub-event discovery and retrieval during natural hazards on social media data" (Wu et al, 2016), "Detecting Natural Hazard-Related Disaster Impacts with Social Media Analytics: The Case of Australian States and Territories" (Yigitcanlar et al, 2022), and "Public Attention to Natural Hazard Warnings on Social Media in China" (Hu et al, 2019).…”

“…PR managers are sensitive to the posts that change with the topic evolving [37], but few studies have supported the topic-level correlation. Although the LDA-based model could extract the topics [2,38], the correlation between the posts inside of topics is still an open question. In this article, the Word Mover's Distance (WMD) method is applied to calculate the correlation of the posts in different topics (sub-events).…”

“…For PR crisis events, it has similar characteristics of emergency or epidemic events, such as natural disasters [2,3], epidemic spreading [4,5], and sports competitions [6,7]. The information related to disaster events can be uploaded and reported, which contributes to the disaster reporting [8].…”

“…Εντοπισμός Υπο-Γεγονότων. Οι ερευνητικές προσπάθειες που έχουν επικεντρωθεί στην ανίχνευση δευτερευόντων συμβάντων από δεδομένα κοινωνικών μέσων [124,84,4,4,66] αναλυούν δεδομένα που ήδη έχουν κάποια σχέση με το γεγονός. Με άλλα λόγια, σαν είσοδο στην μέθοδο δίνονται δεδομένα που αφορούν σε ένα γεγονός αποκλειστικά (π.χ., αγώνας ποδοσφαίρου) και ο στόχος τους είναι να εντοπίσουν σε αυτό τα υπο-γεγονότα που αποτελούν τις σημαντικές στιγμές του γεγονότος (π.χ., γκολ, κόκκινη κάρτα, κίτρινη κάρτα, τελικό σκορ).…”

“…Research efforts have been focused towards the detection of sub-events from social media data ( [124,134,112]). Pohl et al [84] analyze emergencies and disasters by querying a database with keywords related to the emergency and then querying the event dataset for sub-events.…”
