PDF Scaffolder

Bring structure to PDF files

Since PDFs are unstructured by design?, they’re notoriously difficult for machine analysis. Scaffolder ‘understands’ the layout of the PDF - enabling data mining, analytics and more.
Scaffolder was created with scalability and performance in mind. It can be scaled to hundreds of servers and millions of files.

Core Features

  • Determines the areas that are: paragraphs, columns, vector graphics (graphs, diagrams...), tables, footnotes, etc; i.e. identifies the visual ‘blocks’ of content that are apparent to a human.
Snapshots – vector graphics
  • Allows automatic snapshots of the areas.
Language independent
  • Uses computer vision.
  • Works for any left-to-right alphabet.
  • The core software can easily be adapted:
    • want to add interactivity to your PDFs?
    • want all the graph titles?
    • want all the tables?
