Multilingual encoders such as mBERT and XLM-R are pre-trained on unevenly distributed data, so they represent these languages poorly. Relevance-labelled CLIR training data for such languages also barely exists. The authors propose OPTICAL, which… 2. **[Code-Switching Information Retrieval: Benchmarks, Analysis, and the Limits of Current Retrievers](https://md.research.elamur.ai/free/en/papers/zeng-2026-code-switching-information-retrieval-benchmarks/)** *(2026 · 1 citation)* Search engines and RAG pipelines are mostly built and tested on single-language queries, yet many bilingual users mix languages when they search. ## Co-authors here 8 co-authors with a page, the most papers together first. - [Heli Qi](https://md.research.elamur.ai/free/en/authors/heli-qi/) - [Hitomi Yanaka](https://md.research.elamur.ai/free/en/authors/hitomi-yanaka/) - [James Allan](https://md.research.elamur.ai/free/en/authors/james-allan/) - [Naoto Yokoya](https://md.research.elamur.ai/free/en/authors/naoto-yokoya/) - [Qingcheng Zeng](https://md.research.elamur.ai/free/en/authors/qingcheng-zeng/) - [Weihao Xuan](https://md.research.elamur.ai/free/en/authors/weihao-xuan/) - [Yuheng Lu](https://md.research.elamur.ai/free/en/authors/yuheng-lu/) - [Zhiqi Huang](https://md.research.elamur.ai/free/en/authors/zhiqi-huang/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ## Cited by Papers of our library cite their works 16 times (of the 149,439 papers whose bibliographies we read); [1 citing paper with a page here →](https://md.research.elamur.ai/free/en/authors/puxuan-yu/cited-by/).
