  A main goal of Argument Mining (AM) is to analyze an author's stance. Unlike
previous AM datasets focusing only on text, the shared task at the 10th
Workshop on Argument Mining introduces a dataset including both text and
images. Importantly, these images contain both visual elements and optical
characters. Our new framework, TILFA (A Unified Framework for Text, Image, and
Layout Fusion in Argument Mining), is designed to handle this mixed data. It
excels at not only understanding text but also detecting optical characters and
recognizing layout details in images. Our model significantly outperforms
existing baselines, earning our team, KnowComp, the 1st place in the
leaderboard of Argumentative Stance Classification subtask in this shared task.
