About
Hi👋, I'm Qianli Wang and work as a NLP researcher dedicated to advancing the interpretability and explainability of LLMs at Quality and Usability Lab, Technische Universität Berlin under the supervision of Prof. Dr.-Ing. Sebastian Möller, co-supervised by Dr.-Ing. Nils Feldhus.
News
2026-04-29: Our paper about quantization's effect on factual knowledge recall is finally accepted at TrustNLP workshop co-located at ACL 2026!
2026-04-20: One paper led by my thesis student, Yilong, on counterfactual self-explanation enhancement via alignment-as-preference optimization is currently under submission.
2026-04-07: 🌟I am thrilled to shared that two papers are accepted at ACL 2026 about (1) multilingual counterfactual evaluation (Main); (2) actionable mechanistic interpretability survey (Findings)!
2026-03-17: 🤖 One co-authored paper in collaboration with Uni Marburg is in submission. We propose SimXAI, a lightweight LLM-centric conversational layer for ConvXAI systems, which enables better interaction quality and human understanding.
2026-01-06: Two first-authored and three co-authored papers in submission about (1) how quantization affects self-explanations❓collaborated with Pepa Atanasova; (2) feedback-driven iterative counterfactual refinement; (3) NLG evaluation trend survey led by Jing Yang; (4) claim-level grounding traceable generation led by Bohao Chu; (5) mechanistic interpretability application survey led by Hengyuan Zhang.
2025-09-27: 📝 One paper about multilingual counterfactual evaluation in collaboration with LMU and Uni Marburg in submission.
2025-09-01: 🌱 Start my research stay in the CopeNLU group led by Prof. Dr. Isabelle Augenstein in Denmark🧜. Thanks for hosting me and providing a nice starting point for our collaborations!
2025-08-21: 💥Delighted to share that (1) Multilingual Datasets for Custom Input Extraction and Explanation Requests Parsing in Conversational XAI Systems accepted at EMNLP 2025 Findings; (2) Truth or Twist? Optimal Model Selection for Reliable Label Flipping Evaluation in LLM-based Counterfactuals accepted at INLG 2025. See you in Hanoi, Vietnam 🇻🇳 and Suzhou, China 🇨🇳! ✈️
