XMOD-base fine-tuned using
ColBERT-XM methodology on French Translated to Catalan Queries and French Documents from mMARCO/v2.
Essentially, it's ColBERT-XM but fine-tuned on Catalan-French mMARCOv2 in contrast to MSMARCO of the original ColBERT-XM model.
This model was fine-tuned for the "Improving Low-Resource Retrieval Effectiveness using Zero-Shot Linguistic Similarity Transfer" ECIR2025 paper. The source code for the paper can be found
