Call for Participation: NakbaVirality Shared Task Multimodal and Textual Virality Prediction in High-Stakes Discourse
Organized within the second Nakba-NLP Workshop at LREC 2026 https://lrec2026.info/ 11-16 May 2026 Palma de Mallorca, Spain We invite you to participate in the NakbaVirality Shared Task, a new challenge focusing on predicting the reach and engagement of content surrounding the Nakba and the post-October 7th war on Gaza. This task operates at the intersection of NLP, Computer Vision, and Computational Social Science, aiming to understand information diffusion in highly polarized and emotionally charged contexts. Website: https://ezzini.github.io/NakbaVirality/ Registration: https://forms.gle/ufj2gqRyMrrdDs5f9 Motivation Understanding what makes a post "go viral" in conflict zones is critical for analyzing propaganda spread, public sentiment, and information maneuvering. This shared task challenges participants to model "virality" not just as a number, but as a function of nuanced text, graphic imagery, and deep historical context. Tasks We propose two distinct tasks: Task 1: Multimodal Virality Classification
* Goal: Classify posts into Low, Medium, or High virality buckets. * Input: Text + Image. * Challenge: Aligning mismatched modalities (e.g., peaceful image vs. violent interaction) and handling "dog whistles." * Metric: Macro-F1 Score.
Task 2: Textual Virality and Interaction Prediction (Regression)
* Goal: Predict distinct Likability (agreement) and Interactivity (controversy/engagement) scores. * Input: Text only. * Challenge: Distinguishing between content that is "liked" versus content that provokes "debate." * Metrics: Pearson Correlation (r) and MSE.
Data
* Sources: X (Twitter) and Reddit. * Size: ~5,000 anonymized samples (post-Oct 2023). * Content: Posts related to "Gaza," "Nakba," "Palestine," "Israel," etc.
Important Dates
* Jan 1: Release of Training Data (3,500 samples) * Feb 1: Release of Development Data (500 samples) * Feb 15: Evaluation Period Begins * Feb 20: Evaluation Period Ends * Mar 1: Paper Submission Deadline
