While LLMs offer advan-tages in certain applications, their high energy demands prompt a necessary questionfor social scientists: Is it worth considering LLMs for every text analysis task? Thisstudy systematically evaluates the trade-off between performance and energy usageacross computational text analysis methods, including dictionaries, trained classifiers,and open “local” LLMs. Applying sentiment analysis, multi-class classification, andnamed entity recognition to political documents, we measure energy consumption,CO2emissions, correlation with human raters, F1-Score and processing time. /talk/bremen24/ Wed, 20 Nov 2024 00:00:00 +0000 /talk/bremen24/ Abstract: The integration of Artificial Intelligence (AI) into visual communication, particularly within climate change debates, shows a key change in how public discourse is influenced by media (Chian & Lee, 2023; Krishnan et al., 2023). Simultaneously, manipulated images pose a misinformation risk when viewers cannot determine the credibility of what they see (He, 2021). We focus on the polarized topic of climate change to explore how manipulated images shared on Twitter may contribute to polarizing debates between believers and sceptics (deniers) in anthropogenic climate change. /talk/lmu2024/ Tue, 22 Oct 2024 00:00:00 +0000 /talk/lmu2024/ My Presentation: /talk/exeter24/ Wed, 26 Jun 2024 00:00:00 +0000 /talk/exeter24/ Summary: The Centre for Climate Communication and Data Science (C3DS) hosted a seminar on June 26th, 2024, featuring Isaac Bravo from the Technical University of Munich, Germany. Bravo presented his research on the “Visual Framing of Climate Change Imagery on Twitter.” The hybrid seminar was held both in person at the University of Exeter’s Streatham Campus and online via Zoom. Bravo’s research delves into how the framing of climate change imagery on social media platforms like Twitter influences people’s emotional engagement with the issue. /talk/campfire/ Thu, 06 Jun 2024 00:00:00 +0000 /talk/campfire/ Abstract: The emergence of Artificial Intelligence (AI) models is reshaping how scientists interact with this technology when conducting research. This has led to a growing interest in the role and impact of AI in the field of scientific communication over the last few years (Schäfer, 2023). The benefits of this technology that we can find as researchers are varied (Chian & Lee, 2023; Krishnan et al., 2023). Simultaneously, manipulated images pose a misinformation risk when viewers cannot determine the credibility of what they see (He, 2021). /talk/comptext24/ Thu, 02 May 2024 00:00:00 +0000 /talk/comptext24/ Abstract: This study explores the effects of manipulated visual content on polarized climate change debates on Twitter by answering the following research question: Do ‘real’ vs manipulated images about climate change on Twitter lead to different levels of engagement and interactions between believers and skeptics (deniers)? In this research, we analyse the intersection of social science and computer science in the context of climate change discourse on Twitter by adopting a multimodal and computational approach combining automated image and text analysis to examine more than 700,000 images, and replies shared by Twitter users in the year 2019. /talk/eufeels2023/ Wed, 27 Sep 2023 00:00:00 +0000 /talk/eufeels2023/ Abstract: How and to what extent do frames of climate change imagery on social media affect people’s emotional engagement with climate change? How does this vary across different regions across the world where the adverse effects of climate change are expressed differently? Previous studies have focused on a small selection of the most iconic images of climate change, primarily using qualitative methods and data from Western countries. While there are a few comparative studies that contrast how people engage with this phenomenon across countries, we adopt a computational approach that combines framing theory with automated image and text analysis to analyse millions of images, tweets and responses shared by Twitter users during 2019 - 2022. /talk/wapor2023/ Tue, 19 Sep 2023 00:00:00 +0000 /talk/wapor2023/ Abstract: Climate change is a global phenomenon with multidimensional and widespread consequences, which has received considerable media attention in recent decades. Climate change is considered one of the most important challenges faced by the world not only in the present but also in the future. Both scientific and political communities have recognized the urgency of addressing the impacts of this phenomenon, and understanding how people perceive and engage with it. /talk/lmu2023/ Wed, 21 Jun 2023 00:00:00 +0000 /talk/lmu2023/ My Presentation: /talk/tumevent2023/ Fri, 27 Jan 2023 00:00:00 +0000 /talk/tumevent2023/ The Poster Event:
