The models and modeling techniques for popularity of microblogs are studied in this paper. A huge data set based on Sina Weibo, one of the most popular microblogging service, is used in the study.  ...  Then, the temporal dynamics, including lifecycles and tipping-points, of tweets' popularity are studied. For modeling the temporal dynamics, a piece-wise sigmoid model is used.  ...  Detect tipping points based on four conditions; for all piece between tipping points do Estimate N i−1 from last piece (0 for the first one); Estimate parameters a i , b i , and c i by using trust region  ...

Mining Significant Microblogs for Misinformation Identification: An Attention-based Approach [article]

Qiang Liu, Feng Yu, Shu Wu, Liang Wang
2017 arXiv   pre-print
For an event on social media usually consists of multiple microblogs, current methods are mainly based on global statistical features.  ...  Content attention is calculated based textual features of each microblog. Dynamic attention is related to the time interval between the posting time of a microblog and the beginning of the event.  ...  ., mining opposing voices from conflicting viewpoints. Based on the time series of misinformation lifecycle, the temporal characteristics of social context information are captured in [18, 25] .  ...

Rumor Detection and Classification for Twitter Data [article]

Sardar Hamidian, Mona T Diab
2019 arXiv   pre-print
Rumors spread a large quantity of misinformation on microblogs. In this study we address two common issues within the context of microblog social media.  ...  First we detect rumors as a type of misinformation propagation and next we go beyond detection to perform the task of rumor classification. WE explore the problem using a standard data set.  ...  The most relevant related work to ours is that reported in [1] , which addresses rumor detection in Twitter using content-based as well as microblog-specific meme features.  ...

Detect Rumors in Microblog Posts for Low-Resource Domains via Adversarial Contrastive Learning [article]

Hongzhan Lin, Jing Ma, Liangliang Chen, Zhiwei Yang, Mingfei Cheng, Guang Chen
2022 arXiv   pre-print
Extensive experiments conducted on two low-resource datasets collected from real-world microblog platforms demonstrate that our framework achieves much better performance than state-of-the-art methods  ...  However, they are poor at detecting rumors about unforeseen events especially those propagated in different languages due to the lack of training data and prior knowledge (i.e., low-resource regimes).  ...  Different from these works of adaption on multi-modal data and transfer learning of LMs, we focus on language and domain adaptation to detect rumors from low-resource microblog posts corresponding to breaking  ...
