6fanle Submission to the AmericasNLP 2026 Shared Task on Wixarika Image Captioning

Ji Wang, Hanqi Yang


Abstract
This system description presents a Wixarika image captioning system for the AmericasNLP 2026 Shared Task on Cultural Image Captioning for Indigenous Languages. The system uses Spanish as a pivot language, combining CLIP-based image retrieval, Qwen3-VL Spanish caption generation, the official Sheffield-compatible Spanish-to-Wixarika MT model, and character n-gram language-model reranking. We report local 5-fold development results, official test results, error analysis, and implementation details for reproducibility.
