Dataset Card for ECHR Guide Paragraph Diffs
Dataset Summary
This dataset contains paragraph-level and section-level diffs between consecutive versions of European Court of Human Rights case law guide PDFs.
Each JSON file covers one guide version transition and records paragraph-by-paragraph changes (additions, deletions, edits, moves), section structural events (additions, deletions, renames), and cited-case list diffs.
It is the primary source corpus used to build lexgenie/echr-case-linked-guide-diffs — the modeling-ready citation-change layer.
Dataset Structure
Files are organized by guide directory (39 guide directories, 145 JSON files total):
<guide_id>/
diff_<date_a>__<date_b>.json
...
Each JSON file has the following top-level keys:
version_a,version_b: ISO date strings for the two guide snapshotsdelta_days: number of days between versionsguide_title: human-readable guide namesummary: aggregate counts by change typesection_events: list of section-level structural eventsparagraph_changes: list of paragraph-level change recordscited_cases_diff:{added: [...], removed: [...]}citation list diffs

- temporal guide-body analysis across ECHR case law guides
- paragraph-level change classification
- section localization for case-linked guide updates
- training and evaluation of guide-update generation models
Provenance
Produced by Anas Belfathi from Wayback Machine PDF snapshots of ECHR-KS guides (2022–2025). Paragraph alignment and diff computation use a custom PDF-parsing and text-alignment pipeline.
The guide snapshot archive is not publicly distributed due to size and licensing considerations; the Wayback Machine URLs are documented in wayback/*/snapshot_metadata.jsonl in the lexgenie/lexgenie repository.
See lexgenie/echr-guide-citation-diffs for the underlying PDF snapshot metadata and citation-list diffs, and lexgenie/echr-case-linked-guide-diffs for the modeling-ready downstream layer.
