This paper presents an overview of the Im-ageArg shared task, the first multimodal Argument Mining shared task co-located with the 10 th Workshop on Argument Mining at EMNLP 2023.The shared task comprises two classification subtasks -(1) Subtask-A: Argument Stance Classification; (2) Subtask-B: Image Persuasiveness Classification.The former determines the stance of a tweet containing an image and a piece of text toward a controversial topic (e.g., gun control and abortion).The latter determines whether the image makes the tweet text more persuasive.The shared task received 31 submissions for Subtask-A and 21 submissions for Subtask-B from 9 different teams across 6 countries.The top submission in Subtask-A achieved an F1-score of 0.8647 while the best submission in Subtask-B achieved an F1-score of 0.5561.
