Hybrid Batch Training for Zero-Shot Cross-Lingual Retrieval on Domain-Specific Benchmarks

Information retrieval across different languages is an increasingly important challenge in natural language processing. Recent approaches based on multilingual pre-trained language models have achieved remarkable success, yet they often optimize for either monolingual, cross-lingual, or multilingual retrieval performance at the expense of others. This paper proposes a novel hybrid batch training strategy to simultaneously improve zero-shot retrieval performance across monolingual, cross-lingual, and multilingual settings while mitigating language bias. The approach fine-tunes multilingual lang

Research goal: To what extent does the proposed hybrid batch training method improve zero-shot cross-lingual retrieval performance on domain-specific benchmarks (e.g., legal or medical documents) compared to general-domain multilingual models, as measured by MRR and recall@k?
