# Swiss Alert Fidelity — multilingual civil-protection alerts by Apertus 1.5

Evaluation data of the Hack Apertus 2026 Track 2B project *Sturmglocke* (Team Barry): 30 structured alert cases
(natural hazard, zone, invented place names, order, deadline, assembly point, hotline) and 720 alert texts written by
**Apertus 1.5 8B and 70B** in French, Italian, English and Romansh under three conditions, with per-text scores.

## Dataset Details

- **Curated by:** Team Barry (Tushar Agarwal)
- **Language(s):** French, Italian, English, Romansh (Rumantsch Grischun); German source/facts
- **License:** CDLA-Permissive-2.0 (instance-level licences in `metadata.jsonl`)
- **Git repository:** Sturmglocke (Track 2B submission), `track_2b/src/sturmglocke/evals`

## Uses

### Direct Use
Benchmarking whether an LLM preserves safety-critical facts — above all the **official hazard term** — when producing
multilingual public alerts; studying guard pipelines (C2) against plain translation (C0).

### Out-of-Scope Use
Not a source of real alerts. Places and municipalities are invented. Not a measure of general translation quality.

### Specifications
Conditions: **C0** Apertus writes the German alert from the facts, then plain-translates it; **C1** slot-first rendering with
the official term locked; **C2** C1 + deterministic checks + read-back + repair (the shipped pipeline).

## Dataset Structure

- `eval_cases.jsonl` — one structured case per line (`case_id`, hazard, zone, places, action, deadline, assembly point, hotline …)
- `model_responses.jsonl` — one alert text per (case, model, condition, language) with: `hazard_class`
  (official / acceptable / wrong_process / missing), deterministic `checks`, `romansh_unknown_words` (official RG Hunspell),
  semantic verdicts of two independent open-weights judges (`judge_qwen3_235b`, `judge_llama33_70b`), and for Romansh a
  German `backtranslation_de` (ZurichNLP romansh-nllb-1.3b) with `backtranslation_meaning_ok`.
- `metadata.jsonl` — instance-level source and licence.

## Dataset Creation

### Curation Rationale
Translated alerts can preserve every number and time but swap the hazard process (debris flow → landslide/rockslide), which
changes protective behaviour. We needed a reproducible, model-free way to measure this in Swiss languages.

### Source Data
#### Data Collection
Cases from a seeded generator (seed 42). Responses generated at temperature 0 via the CSCS inference API (Oct 2026).
#### Source Data Producers and Data Subjects
Structured facts authored by the team; texts produced by Apertus 1.5. No real persons; no data subjects.
#### Ownership and Consent Management
No personal data; no consent required. Official terminology is referenced by TERMDAT / Pledari Grond entry, single terms only.
#### Data Processing and Quality Control
Deterministic scoring with an official-terminology glossary (TERMDAT ids, Pledari Grond); Romansh vocabulary with the Lia
Rumantscha RG Hunspell dictionary (MIT); semantic read-back by two independent open-weights judges; manual inspection of
failure classes (see the project's technical report).
#### Data Instance Licenses
All instances CDLA-Permissive-2.0 (see `metadata.jsonl`).

### Annotations
#### Annotation Process
Automatic: deterministic checks + LLM judges (declared). No human labels; judge disagreement concentrates on Romansh, which
neither judge reads reliably (documented).
#### Judge agreement (semantic verdict "meaning preserved")

| Languages | n | Agreement | Cohen's kappa |
|---|---|---|---|
| French / Italian / English | 540 | 95.6 % | 0.72 |
| Romansh | 180 | 63.9 % | 0.22 |

#### Annotator Details
Qwen3-235B-A22B-Instruct-2507 and Llama-3.3-70B-Instruct via Hugging Face Inference Providers; ZurichNLP romansh-nllb-1.3b.

## Risks, Bias, and Limitations
Invented names; 30 cases; five hazards. Acceptable-synonym lists are limited; unseen correct synonyms count as "missing".
Romansh judged by dictionary and back-translation, not by native speakers.

### Personally Identifiable Information
None.

### Sensitive Information
None.

### Recommendations
Use the deterministic checks as the primary metric; treat judge verdicts as secondary, especially for Romansh.
