Online Social Networks Event Detection: A Survey [chapter]

Mário Cordeiro, João Gama
2016 Lecture Notes in Computer Science  
Performing event detection on online social networks is no exception, state-of-the-art algorithms rely on text mining techniques applied to pre-known datasets that are being processed with no restrictions  ...  This specific problem of event detection becomes even more serious due to the real-time nature of online social networks.  ...  Modern event detection systems face important challenges when dealing with the high-volume, unbounded nature of today social networks data streams.  ...

Finding Short Lived Events on Social Media

David Kilroy, Simon Caton, Graham Healy
2020 Irish Conference on Artificial Intelligence and Cognitive Science  
Companies have been looking to Social Media for event and trend detection for a number of years to assist in business decision making.  ...  In this paper, we show how subdividing time windows and recombining their results can significantly improve detection.  ...  In order to overcome this problem we first cluster similar events together that -along with some other processing -eliminates them being grouped together (event clustering).  ...

Event Evolution Tracking from Streaming Social Posts [article]

Pei Lee and Laks V.S. Lakshmanan and Evangelos E. Milios
2013 arXiv   pre-print
Intuitively, an event can be viewed as a dense cluster of posts with a life cycle sharing the same descriptive words. There are many previous works on event detection from social streams.  ...  Real life events, which may happen and evolve every minute, are perceived and circulated in post streams by social users.  ...  clusters, and is robust to noise.  ...

2022 arXiv   pre-print
The system allows users to browse trending topics with articles from multiple sources and perspectives.  ...  With thousands of news articles from hundreds of sources distributed and shared every day, news consumption and information acquisition have been increasingly difficult for readers.  ...  Then, we extract the union from generated results as a robust set, and add tags with high confidence from the remainings to the robust set, until the size of robust set reaches K.  ...

Events Detection and Temporal Analysis in Social Media [chapter]

Yawei Jia, Jing Xu, Zhonghu Xu, Kai Xing
2016 Lecture Notes in Computer Science  
Individual events will form clusters in the graph of keywords for a document collection. We built a network of keywords based on their co-occurrence in documents.  ...  Clump of keywords describing an event can be used to analyse the trend of the event. The accuracy of detecting events is over eighty percents with our method.  ...  Conclusions In this paper we proposed an efficient method to extract events from social media texts streams as well as a robust algorithm to identify hot events.  ...
