IPO Tables (HTML) — Random Sample Card

A curated table extraction dataset from SEC filing documents, with raw table HTML plus provenance metadata.

What This Dataset Is

This is a random sample targeting 100 extracted tables per year from filings in 1994–2026.

• Middle years are densely represented at 100 tables/year.
• Edge years can be lower where fewer valid tables were available.
• Tables are extracted directly from filing source files and stored as raw HTML.

Snapshot Stats

• Year range: 1994–2026 (33 years)
• Total extracted tables: 3,099
• Years with 100 tables: 30
• Underfilled edge years:
  • 1994: 35
  • 1995: 64
  • 2026: 0

Files

• sampled_table_html.csv
• sampled_table_html.parquet
• year_summary.csv
• dataset_info.json

Row Schema

Each row contains:

• sample_id: unique row id
• target_year: sampled year bucket
• source_file: source filing path used for extraction
• source_filename: filing filename
• source_extension: file extension (.htm, .html, .txt)
• cik: parsed company identifier (when available)
• accession_from_filename: accession-like id parsed from filename
• table_pick_index_in_filing: selected table index in filing
• table_start_char: char offset start in source text
• table_end_char: char offset end in source text
• table_html: raw extracted table HTML
• table_html_char_length: HTML character length

Intended Use

• Table parsing benchmarks
• Financial document IE experiments
• HTML-to-structured-table extraction
• LLM/RAG evaluation on filing tables

Limitations

• Extraction is HTML-pattern based; malformed markup can reduce recall.
• Some provenance fields depend on filename conventions.
• Edge years may contain fewer tables than the 100 target.
