Dataset for pdf-struct (Logical structure analysis tool for visually structured documents)

This is the dataset to reproduce the experiments for pdf-struct, a tool for extracting fine-grained logical structures (such as boundaries and their hierarchies) from visually structured documents (VSDs) such as PDFs.

Please visit the website at https://github.com/stanfordnlp/pdf-struct for data specifications and other details.

Dataset specification

Our dataset consists of following files:

pdf-struct-dataset/
  - contract_pdf_en/
    - raw/
    - anno/
    - source.tsv
  - contract_pdf_ja/
  - contract_text_en/
  - legistration_pdf_en/
  - LICENSE
  - README.md

Each root-level directory represents a single type of dataset:

  • contract_pdf_en/: English NDAs in PDF format
  • legistration_pdf_en/: English executive orders from local authorities
  • contract_text_en/: English NDAs in visually structured plain text format
  • contract_pdf_ja/: Japanese NDAs in PDF format

Raw documents are located in raw/ directory. Annotated data (generated by pdf-struct init-dataset and then annotated by hand) is located in anno/ directory. source.tsv shows the URL that each document was obtained from.
