I Know What You Meme, Even If it Emerged Today: Understanding Evolving Memes through Open-World Knowledge Acquisition
For researchers and practitioners in meme analysis and multimodal understanding, this work addresses the challenge of dynamic, open-world knowledge acquisition for emerging memes.
The paper tackles the problem of understanding evolving multimodal memes that require up-to-date background knowledge. The proposed Query Retrieve Conclude framework improves knowledge recovery, meme understanding, and downstream detection over zero-shot baselines across three understanding datasets and five detection tasks.
Multimodal memes are dynamic and often require up to date background knowledge for interpretation. Existing methods often overlook such knowledge or rely on fixed parametric knowledge of pretrained models that may be incomplete, outdated, or unavailable for emerging memes. We introduce Query Retrieve Conclude, a zero shot framework that identifies missing knowledge, retrieves open web evidence, and synthesizes evidence grounded background knowledge for meme understanding and detection. We also introduce a curated meme understanding benchmark of recent memes from 2024 to 2026 with external background knowledge annotations. Experiments on three meme understanding datasets and five meme detection tasks show that our framework improves knowledge recovery, meme understanding and downstream detection over zero shot baselines.
