  1. Mitigating Hallucinations and Off-target Machine Translation with Source-Contrastive and Language-Contrastive Decoding (2024 · 47 citations)
    Massively multilingual MT systems, especially in low-resource directions, often produce hallucinations (output unrelated to the input) or off-target translations (output in the wrong language, usually English or the source language).
  2. How Good is AI on Swiss Voting Booklets? A Multilingual OCR and Alignment Benchmark (2026)
    The paper tackles turning Switzerland's federal voting booklets into a clean, machine-readable parallel corpus.
  3. Robust Language Identification for Romansh Varieties (2026)
    Romansh, spoken by roughly 40,000 people in the Swiss canton of Grisons, exists as five regional idioms (Sursilvan, Sutsilvan, Surmiran, Puter, Vallader) plus the supra-regional written standard Rumantsch Grischun (RG).
  4. SwissGov-RSD: A Human-annotated, Cross-lingual Benchmark for Token-level Recognition of Semantic Differences Between Related Documents (2026)
    The paper tackles the recognition of semantic differences (RSD): finding which tokens in two related texts do not mean the same thing.
