Layout-Aware Framework for Scientific Document Differencing
A recently introduced framework for comparing different versions of scientific documents overcomes the shortcomings of both text-sequence and image-based techniques. This innovative method breaks down document versions into semantically categorized components and employs an alignment-first strategy to create correspondences across versions by jointly assessing spatial, content, and structural compatibility. Additionally, it enables type-aware difference reasoning on aligned pairs of elements. The framework facilitates comprehensive change detection across diverse elements, including text, tables, formulas, figures, and layout indicators. Further details can be found in arXiv:2607.14117v2.
