🛠️ transforEmotion crossed 25K CRAN downloads! Paper is out in Computational Communication Research.

Open-source R package for emotion analysis across text, images, and video. Everything runs locally on CPU, no APIs, no cloud.

New: local RAG with small LLMs, VAD scoring, vision model registry, built-in benchmarking, uv for zero-config Python environments.

transforEmotion: An Open-Source R Package for Emotion Analysis Using Transformer-Based Generative AI Models | Amsterdam University Press Journals Online

This software demonstration article introduces transforEmotion, an open-source R package that addresses critical bottlenecks in communication research emotion analysis. Communication researchers currently face three key barriers: (1) modal fragmentation requiring separate tools for text/image/video analysis, (2) rigid emotion taxonomies that don't match theoretical frameworks, and (3) irreproducible workflows dependent on commercial APIs. transforEmotion removes these bottlenecks through unified multimodal processing, zero-shot classification with arbitrary labels, local inference capabilities, and seamless R integration. This enables systematic investigation of emotion dynamics across communication contexts and modalities that were previously technically difficult to analyze.

Welcome to the fediverse! It took me a month of tweaking and building a network to get a feed I really liked. I don’t know if there’s a list of accounts on here that might appeal to you: https://github.com/nathanlesage/academics-on-mastodon

I absolutely love it here. Feels like ‘early days internet’ to me, with everyone excited to be on the platform meeting new people.

🚨 New preprint! Our work on machine learning approach to facial emotion detection in political speeches in on ArXiv.

https://arxiv.org/abs/2304.09914

We processed 77 hours of video and found that populist leaders express negative emotions more often than their non-populist counterparts.

The Face of Populism: Examining Differences in Facial Emotional Expressions of Political Leaders Using Machine Learning

Populist rhetoric employed on online media is characterized as deeply impassioned and often imbued with strong emotions. The aim of this paper is to empirically investigate the differences in affective nonverbal communication of political leaders. We use a deep-learning approach to process a sample of 220 YouTube videos of political leaders from 15 different countries, analyze their facial expressions of emotion and then examine differences in average emotion scores representing the relative presence of 6 emotional states (anger, disgust, fear, happiness, sadness, and surprise) and a neutral expression for each frame of the YouTube video. Based on a sample of manually coded images, we find that this deep-learning approach has 53-60\% agreement with human labels. We observe statistically significant differences in the average score of negative emotions between groups of leaders with varying degrees of populist rhetoric.

Check out the graph below, posted yesterday by Prof. Eliot Jacobson (@EliotJacobson) at Xitter.

What you see there is daily standard deviations of Antarctic sea ice extent for every day from 1989 to 2023, based on the 1991-2020 mean. Each blue line represents the SDs over a full year. Lighter is more recent. 2023 is in red.

Sea ice extent is now 6.4 (‼️) standard deviations below the 1991-2020 mean. That's far beyond any expectations, leaving scientists baffled, not to mention alarmed.

See -- https://www.abc.net.au/news/2023-07-24/antarctic-sea-ice-levels-nosedive-five-sigma-event/102635204

Note that the red line on the graph is not showing the current actual extent of sea ice, but rather deviation from the norm. Ice extent is increasing right now around Antarctica, because it's mid-winter. That means it's peak freeze season, except the ice is not growing anywhere near as fast as it should.

Antarctic sea ice levels dive in 'five-sigma event', as experts flag worsening consequences for planet

Antarctic sea ice has usually been able to recover in winter. But this time it's different, with levels taking a sharp downward turn at a time of year when sea ice usually forms reliably — and experts are worried.
