Manifold-Aware Distance Metrics Enhance Cross-Lingual Retrieval in Multilingual Models

Abstract

Abstract: This report synthesises findings from 12 peer-reviewed papers addressing the following research question: How does the integration of manifold-aware distance metrics (e.g., MA-DPR) with multilingual models like LaBSE affect cross-lingual retrieval performance on benchmarks like MLQA, compared to cosine. Cross-lingual representations of words enable us to reason about word meaning in multilingual contexts and are a key facilitator of cross-lingual transfer when developing natural language processing models for low-resource languages. In this survey, we provide a comprehensive. 8 claims were extracted from source literature; 8 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.5/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research Question

How does the integration of manifold-aware distance metrics (e.g., MA-DPR) with multilingual models like LaBSE affect cross-lingual retrieval performance on benchmarks like MLQA, compared to cosine similarity, when evaluated on OOD language pairs?
