Researchers have developed a novel classification-guided framework for large vision-language models (LVLMs) to improve visual information extraction from complex documents. This approach decouples document-type classification from content extraction and uses in-context learning with dynamic prompt engineering for efficient zero-shot inference across varied layouts. Tested on a bidding dataset, the zero-shot method, utilizing Qwen2.5-VL-7B, significantly outperformed a supervised baseline, achieving a 18.35 percentage point higher F1-score and a 0.23 improvement in normalized edit distance. Further fine-tuning enhanced performance, demonstrating the framework's robustness against common document impairments like seals and watermarks. AI
