Impact of Multilingual Dense Retriever Model Scaling on Low-Resource WebFAQ 2.0 Performance

We present WebFAQ, a large-scale collection of open-domain question answering datasets derived from FAQ-style schema.org annotations. In total, the data collection consists of 96 million natural question-answer (QA) pairs across 75 languages, including 47 million (49\%) non-English samples. WebFAQ further serves as the foundation for 20 monolingual retrieval benchmarks with a total size of 11.2 million QA pairs (5.9 million non-English). These datasets are carefully curated through refined filtering and near-duplicate detection, yielding high-quality resources for training and evaluating multil

Research goal: What is the impact of scaling the multilingual dense retriever model size (e.g., small vs. large) on retrieval performance across low-resource languages in WebFAQ 2.0, as evaluated by recall@k and precision@k on the XGLUE retrieval benchmark?
