Title: Topic Modeling and Progression of American Digital News Media During the Onset of the COVID-19 Pandemic
Authors: Xiangpeng Wan, Michael C. Lucic, Hakim Ghazzai, Yehia Massoud
Abstract summary: Currently, the world is in the midst of a severe global pandemic, which has affected all aspects of people's lives. There is a deluge of COVID-related digital media articles published in the United States, due to the disparate effects of the pandemic. We develop a Natural Language Processing pipeline that is capable of automatically distilling various digital articles into manageable pieces of information.

Abstract: Currently, the world is in the midst of a severe global pandemic, which has affected all aspects of people's lives. As a result, there is a deluge of COVID-related digital media articles published in the United States, due to the disparate effects of the pandemic. This large volume of information is difficult to consume by the audience in a reasonable amount of time. In this paper, we develop a Natural Language Processing (NLP) pipeline that is capable of automatically distilling various digital articles into manageable pieces of information, while also modelling the progression topics discussed over time in order to aid readers in rapidly gaining holistic perspectives on pressing issues (i.e., the COVID-19 pandemic) from a diverse array of sources. We achieve these goals by first collecting a large corpus of COVID-related articles during the onset of the pandemic. After, we apply unsupervised and semi-supervised learning procedures to summarize articles, then cluster them based on their similarities using the community detection methods. Next, we identify the topic of each cluster of articles using the BART algorithm. Finally, we provide a detailed digital media analysis based on the NLP-pipeline outputs and show how the conversation surrounding COVID-19 evolved over time.

Automating the Analysis of Public Saliency and Attitudes towards Biodiversity from Digital Media [0.5175667614430115]
Measuring public attitudes toward wildlife provides crucial insights into our relationship with nature and helps monitor progress toward Global Biodiversity Framework targets. We aim to overcome these challenges by leveraging modern Natural Language Processing (NLP) tools. We introduce a folk taxonomy approach for improved search term generation and employ cosine similarity on Term Frequency-Inverse Document Frequency vectors to filter syndicated articles. We also introduce an relevance filtering pipeline which uses unsupervised learning to reveal common topics, followed by an open-source Large Language Model (LLM) to assign topics to news article titles.

GPT-4V(ision) as A Social Media Analysis Engine [77.23394183063238]
This paper explores GPT-4V's capabilities for social multimedia analysis. We select five representative tasks, including sentiment analysis, hate speech detection, fake news identification, demographic inference, and political ideology detection. GPT-4V demonstrates remarkable efficacy in these tasks, showcasing strengths such as joint understanding of image-text pairs, contextual and cultural awareness, and extensive commonsense knowledge.
