FYI #ACL2026 has an unusual registration system this year, and probably a lot of people who want to attend will not be able to. Spots are limited to 3.5k people, and only presenting authors can register during the first phase. Then, *if* there are spots left, others can try to register.

Turns out, a good way to reduce bias in LLMs is actually to make them more biased first. We came up with a neat way to do that using token based fine-tuning and then steering, getting some interesting results for both real world and fictional biases. Any feedback is welcome!

The high effort solution is to use an LLM to make a browser extension which tracks your academic reading and logs every paper you interact with to github, which builds and publishes a webapp to expose the data. Which, clearly only a crazy weirdo would do. dmarx.github.io/papers-feed/

When we read the news, images can convey different things than text itself. Unlike other works which look at text, we study this as a “multimodal” framing problem & analyze where text and images communicate different “frames”. Checkout our paper here: arxiv.org/abs/2503.20960 @aicentre.dk

New work on multimodal framing! 💫 Some fun results: comparisons of the same frame when expressed in images vs texts. When the "crime" frame is expressed in the article text, there are more political words in the text, but when the frame is expressed in the article image, more police words.
Table 2 from the paper, showing results of the "Fightin' Words" algorithm to rank words by their association with image vs text frames. Results are shown for the "crime" and "quality of life" frames.Figure 13 from the paper showing scatter plots of the topic space (UMAP reduction of a 5k sample of the generated topic descriptions) with points highlighted if they were assigned the "political frame." The two plots display quite different distributions.

🚨New pre-print 🚨 News articles often convey different things in text vs. image. Recent work in computational framing analysis has analysed the article text but the corresponding images in those articles have been overlooked. We propose multi-modal framing analysis of news: arxiv.org/abs/2503.20960

New preprint! Metaphors shape how people understand politics, but measuring them (& their real-world effects) is hard. We develop a new method to measure metaphor & use it to study dehumanizing metaphor in 400K immigration tweets Link: bit.ly/4i3PGm3 #NLP #NLProc #polisky #polcom #compsocialsci 🐦🐦
Screenshot of top half of first page of paper. The paper is titled: "When People are Floods: Analyzing Dehumanizing Metaphors in Immigration Discourse with Large Language Models". The authors are Julia Mendelsohn (University of Chicago) and Ceren Budak (University of Michigan). The top right corner contains a visual showing the sentence "They want immigrants to pour into and infest this country". The caption says: Figure 1: Dehumanizing sentence likening immigrants to the source domain concepts of Water and Vermin via the words "pour" and "infest". 

The abstract text on the left reads: Metaphor, discussing one concept in terms of another, is abundant in politics and can shape how people understand important issues. We develop a computational approach to measure metaphorical language, focusing on immigration discourse on social media. Grounded in qualitative social science research, we identify seven concepts evoked in immigration discourse (e.g. "water" or "vermin"). We propose and evaluate a novel technique that leverages both word-level and document-level signals to measure metaphor with respect to these concepts. We then study the relationship between metaphor, political ideology, and user engagement in 400K US tweets about immigration. While conservatives tend to use dehumanizing metaphors more than liberals, this effect varies widely across concepts. Moreover, creature-related metaphor is associated with more retweets, especially for liberal authors. Our work highlights the potential for computational methods to complement qualitative approaches in understanding subtle and implicit language in political discourse.

Science is political. It wouldn't necessarily have to be partisan. But when one party is opposed to science-based policy, scientists have a choice between saying "you're right, thoughts and prayers are probably as effective as reducing carbon emissions" or saying "fuck that."
