Event Prediction in the Big Data Era

Abstract: Events are occurrences in specific locations, time, and semantics that nontrivially impact either our society or the nature, such as earthquakes, civil unrest, system failures, pandemics, and crimes. It is highly desirable to be able to anticipate the occurrence of such events in advance to reduce the potential social upheaval and damage caused. Event prediction, which has traditionally been prohibitively challenging, is now becoming a viable option in the big data era and is thus experiencing rapid growth, al… Show more

“…In this scenario, four mathematical equations are relied upon to find the effects of the techniques, which are: Accuracy: indicates the overall performance of the techniques (1), Sensitivity is the ratio of heart patients to the total number of patients in the dataset and it gives a positive confirmation of the patient's diagnosis (2), Specificity: is the diagnosis of healthy people as unhealthy (3), and Precision is the marker of a positive diagnosis made by the techniques (4). The last metric is the F1 score, which measures the probability that a positive diagnosis is correct (5).…”

“…In the past years, computers have been benefited from summarizing large amounts of data over time and making comments about events utilizing these data while performing calculations or transmitting data [3], [4]. Nowadays, computers can make decisions about events and know the relationship between events [5]. Also, computers can also solve issues that cannot be mathematically formulated.…”

“…In this section, we discuss research pertinent to our study. Over the last decade, there has been a significant interest in gaining insights into societal events, which are of two types: a) offline (e.g., protest, organized crime, and epidemic) and b) online (e.g., activism, petitions, and rumor) (Deng and Ning, 2021;Zhao, 2021). The modeling of such societal events falls under two broad categories-a) retrospective studies such as event detection (Yang et al, 1998) and summarization (Chakrabarti and Punera, 2011) and b) event forecasting (Zhao et al, 2018), i.e., anticipating future events.…”
