Discourse-aware rumour stance classification in social media using sequential classifiers

Arkaitz Zubiaga, Elena Kochkina, Maria Liakata, Rob Procter, Michal Lukasik, Kalina Bontcheva, Trevor Cohn, Isabelle Augenstein
2018 Information Processing & Management  
We show that sequential classifiers that exploit the use of discourse properties in social media conversations while using only local features, outperform non-sequential classifiers.  ...  Rumour stance classification, defined as classifying the stance of specific social media posts into one of supporting, denying, querying or commenting on an earlier post, is becoming of increasing interest  ...  stances observed around rumours in social media.  ...

From Clickbait to Fake News Detection: An Approach based on Detecting the Stance of Headlines to Articles

Peter Bourgonje, Julian Moreno Schneider, Georg Rehm
2017 Proceedings of the 2017 EMNLP Workshop: Natural Language Processing meets Journalism  
We present a system for the detection of the stance of headlines with regard to their corresponding article bodies. The approach can be applied in fake news, especially clickbait detection scenarios.  ...  We want to contribute to the debate on how to deal with fake news and related online phenomena with technological means, by providing means to separate related from unrelated headlines and further classifying  ...  The setup of our system adheres to this scoring method, and hence applies several classifiers sequentially, as explained in Section 4.  ...

A Survey on Stance Detection for Mis- and Disinformation Identification [article]

Momchil Hardalov, Arnav Arora, Preslav Nakov, Isabelle Augenstein
2022 arXiv   pre-print
Stance detection has been framed in different ways, including (a) as a component of fact-checking, rumour detection, and detecting previously fact-checked claims, or (b) as a task in its own right.  ...  Understanding attitudes expressed in texts, also known as stance detection, plays an important role in systems for detecting false information online, be it misinformation (unintentionally false) or disinformation  ...  aware of what they are reading, thus promoting media literacy and critical thinking.  ...

What goes on inside rumour and non-rumour tweets and their reactions: A Psycholinguistic Analyses [article]

Sabur Butt, Shakshi Sharma, Rajesh Sharma, Grigori Sidorov, Alexander Gelbukh
2021 arXiv   pre-print
In the descriptive line of works, where researchers have tried to analyse rumours using NLP approaches, there isnt much emphasis on psycho-linguistics analyses of social media text.  ...  In recent years, the problem of rumours on online social media (OSM) has attracted lots of attention. Researchers have started investigating from two main directions.  ...  context-aware rumour detection using a sequential classifier To answer these research questions, we used the PHEME-9 to detect rumours from the tweets divided into five news dataset, consisting  ...
