LocuPrompt at SemEval-2026 Task 7: A Multilingual Prompting Framework for Cross-Cultural Everyday Knowledge in LLMs
Summary
LocuPrompt is a multilingual prompting framework designed to enhance large language models' (LLMs) understanding of everyday cultural knowledge, specifically developed for SemEval-2026 Task 7: Everyday Knowledge Across Diverse Languages and Cultures. For Short Answer Questions (SAQ), the framework employs an English-pivot generation strategy combined with back-translation and empirical locale-specific routing, which dynamically assigns the most suitable LLM to each target region. For Multiple-Choice Questions (MCQ), LocuPrompt utilizes parameter-efficient fine-tuning on a robust multilingual base model. This approach integrates locale-aware instructions, framing the LLM as a "local resident" to better capture cultural nuances. The framework aims to bridge cross-lingual cultural gaps through strategic model selection and resource-efficient adaptation, providing a fully reproducible pipeline.
Key takeaway
For NLP Engineers developing multilingual LLMs, you should consider integrating LocuPrompt's strategies to enhance cultural knowledge. Implement empirical locale-specific routing to dynamically assign optimal models for different regions, and apply parameter-efficient fine-tuning with locale-aware instructions that frame your LLM as a "local resident." This approach can significantly bridge cross-lingual cultural gaps and ensure more accurate, contextually relevant responses in diverse linguistic environments.
Key insights
LocuPrompt enhances LLM cultural knowledge via multilingual prompting, combining pivot generation, back-translation, and locale-specific adaptation for diverse question types.
Principles
- Multilingual LLM performance benefits from locale-specific routing.
- Framing LLMs as "local residents" improves cultural understanding.
- English-pivot generation aids cross-lingual knowledge transfer.
Method
For SAQ, use an English-pivot generation strategy with back-translation and empirical locale-specific LLM routing. For MCQ, apply parameter-efficient fine-tuning with locale-aware instructions on a multilingual base model.
In practice
- Implement locale-specific LLM routing for diverse regions.
- Apply PEFT with "local resident" instructions for cultural tasks.
- Use back-translation in English-pivot generation for SAQ.
