Generative Query Expansion with Multilingual LLMs for Cross-Lingual Information Retrieval

arXiv — cs.CLTuesday, November 25, 2025 at 5:00:00 AM
  • A recent study has evaluated the effectiveness of multilingual large language models (mLLMs) in generative query expansion for cross-lingual information retrieval. This approach shifts from traditional semantic augmentation to generating pseudo-documents, enhancing the retrieval of relevant information from diverse languages. The findings indicate that query length significantly influences the effectiveness of prompting techniques used in this context.
  • The development of mLLMs and their application in query expansion is crucial for improving cross-lingual information retrieval systems. By generating pseudo-documents, these models can better connect short user queries with extensive documents, potentially increasing the accuracy and relevance of search results across different languages and contexts.
  • This advancement reflects a broader trend in artificial intelligence, where the integration of generative techniques and multilingual capabilities is becoming essential. As the demand for effective cross-lingual information retrieval grows, the exploration of various prompting strategies and their impact on retrieval performance highlights ongoing challenges in linguistic diversity and model optimization.
