Data Summarization with Social Contexts

Hao Zhuang, Rameez Rahman, Xia Hu, Tian Guo, Pan Hui, Karl Aberer
2016 Proceedings of the 25th ACM International on Conference on Information and Knowledge Management - CIKM '16  
To tackle these challenges, in this paper, we focus on exploiting social contexts to summarize social data while preserving topics in the original dataset. We take Twitter data as a case study.  ...  Existing methods find such subsets with objective functions based on data properties such as representativeness or informativeness but do not exploit social contexts, which are distinct characteristics  ...  CONCLUSION AND FUTURE WORK Summarizing social data gives us the opportunity to exploit social contexts for data summarization.  ...

Social context summarization

Zi Yang, Keke Cai, Jie Tang, Li Zhang, Zhong Su, Juanzi Li
2011 Proceedings of the 34th international ACM SIGIR conference on Research and development in Information - SIGIR '11  
We study a novel problem of social context summarization for Web documents. Traditional summarization research has focused on extracting informative sentences from standard documents.  ...  With the rapid growth of online social networks, abundant user generated content (e.g., comments) associated with the standard documents is available.  ...  Basic Idea In our Twitter data set, each Web document is associated with a social context.  ...

Collective Personal Profile Summarization with Social Networks

Zhongqing Wang, Shoushan Li, Fang Kong, Guodong Zhou
2013 Conference on Empirical Methods in Natural Language Processing  
In this paper, we address the task of personal profile summarization by leveraging both personal profile textual information and social networks.  ...  Here, using social networks is motivated by the intuition that, people with similar academic, business or social connections (e.g. co-major, co-university, and cocorporation) tend to have similar experience  ...  social contexts.  ...

Neural Abstractive Unsupervised Summarization of Online News Discussions [article]

Ignacio Tampe Palma, Marcelo Mendoza, Evangelos Milios
2021 arXiv   pre-print
Our novel approach provides a summary that represents the most relevant aspects of a news item that users comment on, incorporating the social context as a source of information to summarize texts in online  ...  Social media brings a hurdle to summarization techniques since it requires addressing a multi-document multi-author approach.  ...  Mendoza acknowledges funding from the Millennium Institute for Foundational Research on Data.

Applying Automatic Text Summarization for Fake News Detection [article]

Philipp Hartl, Udo Kruschwitz
2022 arXiv   pre-print
Apart from the benefit of using automatic text summarization techniques we also find that the incorporation of contextual information contributes to performance gains.  ...  The shift to news consumption via social media has been one of the drivers for the spread of misleading and deliberately wrong information, as in addition to it of easy use there is rarely any veracity  ...  context data than without.  ...

QUERY-BASED SUMMARIZATION METHODS FOR CONVERSATIONAL AGENTS: AN OVERVIEW

Ketakee Nimavat
2017 International Journal of Advanced Research in Computer Science  
The data will be in the form of Social media posts, content websites and other user generated text content from which the user shall require tailored information from and about the data.  ...  Along with that, the need for a proper framework to mine relevant knowledge from the said data is acknowledged and the challenges that a conversational agent would hence face are identified.  ...  Hence, new methods to deal with data must include considerations for context, scale and dynamic nature of learning.  ...

Harnessing Popularity in Social Media for Extractive Summarization of Online Conversations

Ryuji Kano, Yasuhide Miura, Motoki Taniguchi, Yan-Ying Chen, Francine Chen, Tomoko Ohkuma
2018 Proceedings of the 2018 Conference on Empirical Methods in Natural Language Processing  
We leverage a popularity measure in social media as a distant label for extractive summarization of online conversations. In social media, users can vote, share, or bookmark a post they prefer.  ...  We evaluate the results with ranking metrics, and show that our model outperforms the baseline models which directly use popularity as a measure of informativeness.  ...  In previous research, few or no training data was adopted because of a lack of labeled data. Our model harnesses a vast amount of data from social media.  ...

TLDR9+: A Large Scale Resource for Extreme Summarization of Social Media Posts [article]

Sajad Sotudeh, Hanieh Deilamsalehy, Franck Dernoncourt, Nazli Goharian
2021 arXiv   pre-print
While most existing summarization corpora contain data in the order of thousands to one million, generation of large-scale summarization datasets in order of couple of millions is yet to be explored.  ...  Recent models in developing summarization systems consist of millions of parameters and the model performance is highly dependent on the abundance of training data.  ...  Prevalence of social media platforms has provided communities with an opportunity to ex- change different types of data while interacting with each other.  ...
