Cross-lingual Zero-shot Retrieval Accuracy of WebFAQ vs. TyDi QA Models on Low-resource XQuAD Subsets

Benefiting from transformer-based pre-trained language models, neural ranking models have made significant progress. More recently, the advent of multilingual pre-trained language models provides great support for designing neural cross-lingual retrieval models. However, due to unbalanced pre-training data in different languages, multilingual language models have already shown a performance gap between high and low-resource languages in many downstream tasks. And cross-lingual retrieval models built on such pre-trained models can inherit language bias, leading to suboptimal result for low-reso Research goal: How does the cross-lingual zero-shot retrieval accuracy of models trained on WebFAQ compare to those trained on TyDi QA when evaluated on low-resource language subsets of XQuAD?
