Scientific and Technical Document Analysis: A Comprehensive Review of Techniques, Tools, and Applications

Document analysis is a crucial task in various fields like research, business, and government. However, processing visually rich documents like PDFs or Word documents can be challenging due to their semi-structured nature. Traditional rule-based or machine learning approaches often struggle with compatibility issues or lack of relevant data for training. To overcome these limitations, the authors propose a novel pipeline called WordScape, designed to create curated datasets for large-scale multimodal document understanding models.
WordScape’s key innovation is its ability to source and annotate high-quality, diverse, and visually rich documents at scale. The pipeline can handle millions of pages with accurate text, layout, and language annotations. By integrating quality filters, malware detection, and metadata extraction, WordScape ensures the accuracy and reliability of the resulting dataset.
The authors highlight the importance of bounding box annotations for certain semantic entities like headings, which may be affected by formatting inconsistencies. To address this challenge, they plan to explore additional characteristics of the dataset, such as toxic content or language identification.
In summary, WordScape is a powerful tool for automatic document understanding that can help researchers and organizations process vast amounts of visually rich documents with ease. By leveraging advanced techniques like deep learning, WordScape streamlines the data extraction process while maintaining high accuracy and reliability.
