Information Extraction from Visually Rich Documents using LLM-based Organization of Documents into Independent Textual Segments (2025.acl-long)
Copied to clipboard
| Challenge: | Specialized non-LLM NLP-based solutions lack reasoning and are not able to infer values not explicitly present in documents. |
| Approach: | They propose a novel LLM-based approach that organizes VRDs into localized semantic textual segments called semantic blocks. |
| Outcome: | The proposed approach outperforms the state-of-the-art on public VRD benchmarks by 1-3% in F1 scores and is resilient to document formats previously not encountered. |
