Hello! I’m Jiaan Wang (王佳安). I am currently a NLP researcher at WeChat AI, Tencent in Beijing. Before that, I received B.Eng. and M.S from Soochow University (2016-2023), advised by Prof. Zhixu Li (now at Renmin University of China) and Dr. Fandong Meng (from WeChat AI). I also collaborated closely with Dr. Jiarong Xu (from Fudan University) and Dr. Jianfeng Qu (from Soochow University).

My primary research interests lie in the area of Natural Language Processing & Large Language Models with the following research topics:

• Multi-lingual NLP:
  • Machine translation, e.g., DRT (ACL 2025 Findings), DeepTrans (arXiv preprint 2025), ExTrans (arXiv preprint 2025), SCD (ACL 2024) and RAGtrans (arXiv preprint 2024).
  • Multi-lingual summarization, e.g., M2MS empirical study (ACL 2025), PISCES (ACL 2023), MM-Sum (ACL 2023), D2TV (EMNLP 2023 Findings).
  • Cross-Lingual Summarization, e.g., CLS Survey (TACL 2022), Translationese in CLS (EMNLP 2023 Findings), ClidSum (EMNLP 2022), Perseus (WSDM 2023).
  • Cross-lingual knowledge editing, e.g., Bi-ZsRE (ACL 2024).
• NLG Evaluation: Is ChatGPT a Good NLG Evaluator? (NewSumm@EMNLP 2023).
• Dialogue Generation: (1) Knowledge-grounded dialogue, e.g., EnCo (AAAI 2024). (2) Emotion support dialogue, e.g., ESC-Eval (EMNLP 2024); (3) Role-Playing dialogue.
• Knowledge Graphs: (1) Multi-modal knowledge graphs, e.g., M2ConceptBase (CIKM 2024), AspectMMKG (CIKM 2023); (2) Temporal knowledge graphs, e.g., MusTQ (ACL 2024 Findings).
• Graph Mining: Graph pre-training, e.g., Wild-GAD (KDD 2025)， EmojiGraph (EMNLP 2024), W2PGNN (KDD 2023).

We are hiring several research interns (location: Beijing) about LLM and multilingual NLP. Please feel free to contact me if you are interested.
