A Symbolic Character-Aware Model for Solving Geometry Problems

Understand

AI has made significant progress in solving math problems, but geometry problems remain challenging due to their reliance on both text and diagrams.

• In the text description, symbolic characters such as "$\triangle$ABC" often serve as a bridge to connect the corresponding diagram.
• However, by simply tokenizing symbolic characters into individual letters (e.g., 'A', 'B' and 'C'), existing works fail to study them explicitly and thus lose the semantic relationship with the diagram.
• In this paper, we develop a symbolic character-aware model to fully explore the role of these characters in both text and diagram understanding and optimize the model under a multi-modal reasoning framework.
