| # 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 snapshots |
| - `delta_days`: number of days between versions |
| - `guide_title`: human-readable guide name |
| - `summary`: aggregate counts by change type |
| - `section_events`: list of section-level structural events |
| - `paragraph_changes`: list of paragraph-level change records |
| - `cited_cases_diff`: `{added: [...], removed: [...]}` citation list diffs |
|
|
| ### Paragraph change record fields |
|
|
| | Field | Description | |
| |---|---| |
| | `change_type` | One of: `unchanged`, `minor_edit`, `citation_added`, `citation_updated`, `citation_removed`, `reformulation`, `paragraph_added`, `paragraph_deleted`, `section_moved`, `section_moved_modified` | |
| | `section_path` | Hierarchical section identifier | |
| | `section_title` | Section heading text | |
| | `section_level` | Nesting depth | |
| | `para_num_a`, `para_num_b` | Paragraph index in version A and B | |
| | `similarity` | Text similarity score (0–1) | |
| | `text_a`, `text_b` | Paragraph text before and after | |
| | `citations_added`, `citations_removed` | Per-paragraph citation deltas | |
| | `moved_from`, `moved_to` | Section move provenance (when applicable) | |
|

| ## Intended Use |
|
|
| This dataset is intended for: |

| - 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. |
