Zhaochun Ren, Jun Ma, Shuaiqiang Wang, Yang Liu
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
To handle this issue, this paper investigates the task of Web Forum Thread Summarization (WFTS), aiming to give a brief statement of each thread that involving multiple dynamic topics.  ...  With an increasingly amount of information in web forums, quick comprehension of threads in web forums has become a challenging research problem.  ...  Web Forum Thread Summarization works by extracting a group of sentences from all posts in one thread to constitute the summary.  ...

Epidemic model for information diffusion in web forums: experiments in marketing exchange and political dialog

Jiyoung Woo, Hsinchun Chen
2016 SpringerPlus  
The model was evaluated on a large longitudinal dataset from the web forum of a major retail company and from a general political discussion forum.  ...  The fitting results showed that the SIR model is a plausible model to describe the diffusion process of a topic.  ...  Additionally, we can estimate how many authors have latent interest on each topic at the initial phase of the diffusion process.  ...

NesTPP: Modeling Thread Dynamics in Online Discussion Forums [article]

Chen Ling, Guangmo Tong, Mozi Chen
2020 arXiv   pre-print
In this paper, we design a novel temporal point process model to characterize information cascades in online discussion forums.  ...  Online discussion forum creates an asynchronous conversation environment for online users to exchange ideas and share opinions through a unique thread-reply communication mode.  ...  Other than the point process based methods, there also exist a large volume of feature-based approaches ( [12] , [27] - [29] ) that study the information propagation pattern mostly in friendship-based  ...

Incorporating Topic Aspects for Online Comment Convincingness Evaluation

Yunfan Gu, Zhongyu Wei, Maoran Xu, Hao Fu, Yang Liu, Xuanjing Huang
2018 Proceedings of the 5th Workshop on Argument Mining  
In order to test the effectiveness of our proposed model, we annotate topic information on top of a public dataset for argument convincingness evaluation.  ...  Our model makes use of graph convolutional network to utilize implicit topic information within a discussion thread to assist the evaluation of convincingness of each single comment.  ...  In this paper, we propose to incorporate latent topic aspects information to evaluate the convincingness of comments in online forum.  ...
