DFKI-MLT at SemEval-2026 TASK 7: Steering Multilingual Models Towards Cultural Knowledge
Yusser Al Ghussin, Daniil Gurgurov, Yasser Hamidullah +3
Large language models (LLMs) are increasingly used across diverse linguistic and cultural contexts, yet their cultural knowledge remains uneven across regions and languages. We pre…
DualFact+: A Multimodal Fact Verification Framework for Procedural Video Understanding
Cennet Oguz, Yasser Hamidullah, Josef van Genabith +1
We introduce DualFact, a dual-layer, multimodal factuality evaluation framework for procedural video captioning. DualFact separates factual correctness into conceptual facts, captu…
A Critical Study of Automatic Evaluation in Sign Language Translation
Shakib Yazdani, Yasser Hamidullah, Cristina España-Bonet +2
Automatic evaluation metrics are crucial for advancing sign language translation (SLT). Current SLT evaluation metrics, such as BLEU and ROUGE, are only text-based, and it remains…
Seeing, Signing, and Saying: A Vision-Language Model-Assisted Pipeline for Sign Language Data Acquisition and Curation from Social Media
Shakib Yazdani, Yasser Hamidullah, Cristina España-Bonet +1
Most existing sign language translation (SLT) datasets are limited in scale, lack multilingual coverage, and are costly to curate due to their reliance on expert annotation and con…
Spatio-temporal Sign Language Representation and Translation
Yasser Hamidullah, Josef van Genabith, Cristina España-Bonet
This paper describes the DFKI-MLT submission to the WMT-SLT 2022 sign language translation (SLT) task from Swiss German Sign Language (video) into German (text). State-of-the-art t…
SONAR-SLT: Multilingual Sign Language Translation via Language-Agnostic Sentence Embedding Supervision
Yasser Hamidullah, Shakib Yazdani, Cennet Oguz +2
Sign language translation (SLT) is typically trained with text in a single spoken language, which limits scalability and cross-language generalization. Earlier approaches have repl…
Sign Language Translation with Sentence Embedding Supervision
Yasser Hamidullah, Josef van Genabith, Cristina España-Bonet
State-of-the-art sign language translation (SLT) systems facilitate the learning process through gloss annotations, either in an end2end manner or by involving an intermediate step…
Grounding or Guessing? Visual Signals for Detecting Hallucinations in Sign Language Translation
Yasser Hamidullah, Koel Dutta Chowdhury, Yusser Al Ghussin +4
Hallucination, where models generate fluent text unsupported by visual evidence, remains a major flaw in vision-language models and is particularly critical in sign language transl…
