Evaluating Large Language Models for Cross-Lingual Retrieval (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) have been evaluated as second-stage reranking models for monolingual IR, but a systematic comparison is lacking for cross-lingual reranked IR. |
| Approach: | They propose to use machine translation to evaluate rerankers in cross-lingual IR . they find that LLMs perform better than LLM-based reranked models . |
| Outcome: | The proposed model improves cross-lingual IR but relies on machine translation for the first stage. |
Cross-Dialect Information Retrieval: Information Access in Low-Resource and High-Variance Languages (2025.coling-main)
Copied to clipboard
| Challenge: | lexical gaps between dialects in cross-lingual information retrieval (CLIR) are caused by orthographic variations and different regional expressions. |
| Approach: | They propose a dataset that consists of seven German dialects extracted from Wikipedia. |
| Outcome: | The proposed dataset consists of seven German dialects extracted from Wikipedia. |
