A comparative study evaluated 10 actively maintained open-source PDF parsing tools for full-text extraction and table detection across six diverse document categories using the DocLayNet dataset. The research found that rule-based tools perform effectively for general text in most document types, while learning-based models like Nougat and Table Transformer achieve superior performance for scientific documents and complex table detection respectively.

Key insights

  • Rule-based PDF parsing tools generally achieve high accuracy for full-text extraction in straightforward document types like Financial, Law, and Manuals.
  • Complex document categories, such as Scientific articles with mathematical expressions and patents, significantly challenge rule-based parsers, leading to notable performance drops.
  • Learning-based models like Nougat for text and Table Transformer (TATR) for tables demonstrate superior performance in handling complex layouts and diverse table structures, outperforming rule-based methods in these areas.
