Happy to share that our work on multi-modal framing analysis of news was accepted to #EMNLP2025!
Understanding news output and embedded biases is especially important in today's environment and it's imperative to take a holistic look at it.
Looking forward to presenting it in Suzhou!

🚨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

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!

Greta Thunberg, after trying to do the humanitarian work our governments are supposed to be doing: "Whatever the odds are, we have to keep trying…when you look at the state of the world, everything feels meaningless — but unless you try to do everything you can, that's when we lose our hope, no?"
Greta Thunberg, describing the Gaza aid flotilla effort:
"It's more important than ever because of the siege and because of the systematic starvation of over 2 million people and the full-blown, live-streamed genocide…we cannot accept just witnessing all this and doing nothing."

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.

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.

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”.
