Abstract
In the daily work, vast amounts of documents are stored in pixel-based formats such as images and scanned PDFs, posing challenges for efficient database management and data processing. Existing methods often fragment the parsing process into the pipeline of separated subtasks on the layout element level, resulting in incomplete semantics and error propagation. Even though models based on multi-modal large language models (MLLMs) mitigate the issues to some extent, they also suffer from absent or sub-optimal grounding ability for visual information. To address these challenges, we introduce the Intelligent Document Parsing (IDP) framework, an end-to-end document parsing framework leveraging the vision-language priors of MLLMs, equipped with an elaborately designed document representation and decoding mechanism to decouple the content parsing and layout grounding to fully activate the potential of MLLMs for document parsing. Experimental results demonstrate that the IDP method surpasses existing methods, significantly advancing MLLM-based document parsing.
