| # DECKEDIT-BENCH — Datasheet | |
| Following the *Datasheets for Datasets* structure (Gebru et al., 2021). | |
| ## Motivation | |
| Instruction-guided document editing is largely evaluated on plain text or | |
| single-shape image edits. Real presentation editing is harder: instructions are | |
| under-specified, targets must be located among many shapes, edits repeat across | |
| slides, and a good system must change only what was asked while preserving | |
| everything else. DECKEDIT-BENCH provides real decks and natural-language | |
| instructions to measure these abilities, with an explicit axis for **preservation** | |
| (non-target damage) alongside instruction-following accuracy. | |
| ## Composition | |
| - **Instances.** 183 `(deck, instruction)` pairs over 28 `.pptx` decks. | |
| - **Deck tiers** (by slide count): Short ≤10 (9 decks), Medium 11–30 (12), | |
| Long >30 (7). Largest deck: 50 slides. | |
| - **Instructions per tier:** Short 54 · Medium 81 · Long 48. | |
| - **Cells:** ES 17 · EC 57 · PS 87 · PC 22 (see TAXONOMY.md). | |
| - **Languages:** source decks are en (21) / ko (7); some instructions ask for | |
| translation into en/ko/ja/fr/es/zh. | |
| - **Domains** (28 decks): AI/ML/Speech-NLP research (12), STEM lecture & | |
| engineering (4), Humanities & general (4), Business reports (3), | |
| Architecture/Urban/Visual (3), Medical/Bio (2). | |
| - **Visuals:** decks variously contain pictures, tables, and charts; per-deck | |
| inventory is in `deck_info.json` (`visuals`). | |
| - **Two fully-synthetic decks** (`02_RemoteWorkSurvey`, `09_ApexAnalytics`) are | |
| chart-heavy fixtures authored for this benchmark. | |
| Each instance carries: `deck_id`, `id`, `cell`, `ops_per_slide`, `actions`, | |
| `derived_from` (template id or `deck-specific`), `intent`, `text`. | |
| ### Known imbalances / limitations | |
| - REPLACE accounts for ~75 % of actions; ADD/DELETE/SLIDE are sparser. | |
| - `SLIDE` actions appear only in PS cells; ES/EC/PC × SLIDE = 0. | |
| - `slide-mgmt` (add/delete/duplicate slide) is barely tested. | |
| - Multi-action instructions (≥2 distinct actions) are rare. | |
| - Domain skew toward AI/Speech research (~43 % of decks); legal/finance/sales/ | |
| medical-chart are under-represented — an external-validity caveat. | |
| - Not every instruction is deterministically checkable: ~75 % are | |
| (text/color/font/chart-attr/background); translate/summarize/"important parts" | |
| require an LLM/vision judge. | |
| ## Collection process | |
| Decks are real lecture, seminar, paper-review, proposal, and report | |
| presentations contributed by their authors (with permission), plus two | |
| synthetic chart decks. Instructions were authored for this benchmark to cover | |
| the Cell × Action × Target space; 92 derive from 14 reusable templates | |
| (`taxonomy.json`), 91 are deck-specific. No model outputs are included in the | |
| released data. | |
| ## Preprocessing / cleaning / anonymization | |
| All decks were sanitized for personal and third-party data. PII in `.pptx` | |
| hides in **non-visible metadata layers**; every layer below was scrubbed and the | |
| result re-verified (0 residual names / emails / template watermarks across all | |
| 28 decks): | |
| 1. **Document properties** — `docProps/core.xml`, `app.xml`: `creator`, | |
| `lastModifiedBy`, `title`, `subject`, `keywords`, `Company`, `Manager` cleared. | |
| 2. **Comment / coauthor records** — `ppt/authors.xml`, `ppt/commentAuthors.xml`: | |
| real author names anonymized to `Author A/B/…` (5 decks), initials blanked. | |
| 3. **Coauthoring revision history** — `ppt/changesInfos/changesInfo*.xml`: | |
| `chgData name=` author names anonymized (4 decks). | |
| 4. **Embedded emails** — real addresses replaced with `example.*` placeholders. | |
| `11_FourthIndustryStartup` was originally built on a commercial third-party | |
| template; it was **rebuilt copyright-clean**: original text and styling preserved | |
| verbatim, the template's full-slide background and all raster images removed, | |
| template-vendor watermarks stripped, and slide imagery replaced with | |
| license-clean Unsplash photos (then downsized to 1920 px). Its instruction | |
| targets (team identifier, author list, four category labels, a replaceable | |
| image, the startup-pitch body) are preserved, so its prompts behave as before. | |
| ## Uses | |
| Intended for evaluating instruction-guided `.pptx` editing systems | |
| (instruction-following accuracy, target localization, pattern compression, | |
| and content preservation). Not intended as training data for, or evaluation of, deck | |
| *generation* from scratch. The decks reflect their source domains and languages | |
| and should not be treated as a representative sample of all presentations. | |
| ## Distribution | |
| Released as static files (decks + `prompts.jsonl` + `taxonomy.json` + | |
| `deck_info.json` + docs). Decks retain original-resolution media (~1 GB total) | |
| and require Git LFS or a large-file dataset host. License: **CC BY-NC 4.0** | |
| (`LICENSE`); third-party image/figure attributions in `THIRD_PARTY_NOTICES.md`. | |
| This v1 release is **data only** — the evaluation/judge harness is not included. | |
| ## Maintenance | |
| When adding decks or instructions: update `deck_info.json`; add the | |
| instructions to the per-deck source and regenerate `prompts.jsonl` / | |
| `taxonomy.json`; re-run the PII scrub and coverage audit. The benchmark is | |
| intended to grow toward the gaps listed under *Known imbalances*. | |
