Zero-shot Cross-lingual Retrieval Performance of Dense Models Trained on WebFAQ vs. Balanced Multilingual Datasets

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: How does the zero-shot cross-lingual retrieval performance of dense retrieval models trained on WebFAQ's 47 million non-English QA pairs compare to models trained on a balanced multilingual dataset of 10-20 languages on the TyDi QA benchmark?
