Later sub-questions then refer to an earlier result through a pronoun such as "this author" instead of naming the entity. The authors call this failure "lost-in-retrieval." Without the key entity, retrieval for these… 2. **[Asymmetric On-Policy Distillation: Bridging Exploitation and Imitation at the Token Level](https://md.research.elamur.ai/free/en/papers/jia-2026-asymmetric-policy-distillation-bridging-exploitation/)** *(2026 · 6 citations)* On-policy distillation (OPD) lets a small student learn from its own sampled outputs, with a teacher scoring each token by the gap between their log-probabilities. ## All works 5 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. **[Knowledge Graph Alignment Network with Gated Multi-Hop Neighborhood Aggregation ↗](https://doi.org/10.1609/aaai.v34i01.5354) Proceedings of the AAAI Conference on Artificial Intelligence · no summary yet**Zequn Sun et al.*2020 · 372 citations* 2. **[Multi-view Knowledge Graph Embedding for Entity Alignment ↗](https://doi.org/10.24963/ijcai.2019/754) International Joint Conference on Artificial Intelligence · no summary yet**Qinghe Zhang et al.*2019 · 285 citations* 3. **[Knowledge Association with Hyperbolic Knowledge Graph Embeddings ↗](https://aclanthology.org/2020.emnlp-main.460/) Proceedings of the 2020 Conference on Empirical Methods in Natural Language Processing (EMNLP) · no summary yet**Zequn Sun et al.*2020 · 93 citations* 4. **[Mitigating Lost-in-Retrieval Problems in Retrieval Augmented Multi-Hop Question Answering](https://md.research.elamur.ai/free/en/papers/zhu-2025-mitigating-lost-retrieval-problems-retrieval/) [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/)**Rongzhi Zhu, Xiangyu Liu, Zequn Sun, et al.*2025 · 16 citations* 5.
