Towards Understanding Persuasion in Computational Argumentation [article]

Esin Durmus
2021 arXiv   pre-print
We also investigate the role of social interactions and engagement in understanding users' success in online debating over time.  ...  Then, we propose models to understand the role of the audience's prior beliefs on their perception of arguments.  ...  Linguistic features We extract linguistic features separately for both the PRO and CON side of the debate (combining all the utterances of each side across the different turns).  ...

Exploiting Debate Portals for Semi-Supervised Argumentation Mining in User-Generated Web Discourse

Ivan Habernal, Iryna Gurevych
2015 Proceedings of the 2015 Conference on Empirical Methods in Natural Language Processing  
We propose novel features that exploit clustering of unlabeled data from debate portals based on a word embeddings representation.  ...  Using these features, we significantly outperform several baselines in the cross-validation, cross-domain, and cross-register evaluation scenarios.  ...  Association for Computational Linguistics.

What Changed Your Mind: The Roles of Dynamic Topics and Discourse in Argumentation Process [article]

Jichuan Zeng, Jing Li, Yulan He, Cuiyun Gao, Michael R. Lyu, Irwin King
2020 arXiv   pre-print
In our world with full of uncertainty, debates and argumentation contribute to the progress of science and society.  ...  The results show that our model outperforms state-of-the-art models in identifying persuasive arguments via explicitly exploring dynamic factors of topic and discourse.  ...  For example, it works for the classic Oxford-style debate involving two sides, where one argues "for" a statement and the other "against".  ...

Recognizing Conversational Interaction Based on 3D Human Pose [chapter]

Jingjing Deng, Xianghua Xie, Ben Daubney, Hui Fang, Phil W. Grant
2013 Lecture Notes in Computer Science  
We believe this is among one of the first work that is devoted to conversational interaction classification using 3D pose features and to show this task is indeed possible.  ...  We adopt Kinect sensors to extract low level temporal features.  ...  The former is used to measure the lower arm joints on the left side and the latter is for right side.  ...
