A Practical Study of Information Retrieval Methods across Domains](https://md.research.elamur.ai/free/en/papers/nguyen-2026-which-works-best-vietnamese-practical/)** *(2026 · 2 citations)* Retrieval quality limits what a RAG-based question answering system can achieve. For Vietnamese, however, nobody had compared retrieval approaches across many domains in one consistent setup. Earlier work usually tested a single area, such as law, or used clean curated QA sets. 2. **[HiGraAgent: Dual-Agent Adaptive Reasoning over Hierarchical Knowledge Graph for Open Domain Multi-hop Question Answering](https://md.research.elamur.ai/free/en/papers/luu-2026-higraagent-dual-agent-adaptive-reasoning/)** *(2026 · 1 citation)* Open-domain multi-hop QA is difficult for two reasons. Questions can have complex internal structure, and the supporting evidence is often spread over many passages. The authors argue that "multi-hopness" is not fixed by the question alone. It depends on how fragmented the available context is, and sequential… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[LAMPAT: Low-Rank Adaption for Multilingual Paraphrasing Using Adversarial Training ↗](https://doi.org/10.1609/aaai.v38i16.29804) arXiv:2401.04348 · no summary yet**Khoi M.Le et al.*2024 · 11 citations* 2. **[Which Works Best for Vietnamese?
