Biography
I am currently a Ph.D. student advised by Prof. Chuxu Zhang. Prior to this, I obtained my master's degree under the supervision of Prof. Youhuan Li. I am deeply grateful to Prof. Youhuan Li, whose guidance allowed me to experience the fascinating world of scientific research.

paper
(Graph Structure) This paper proposes G-Substrate, a framework that treats graph structure as a persistent "structural substrate" shared across modalities and tasks rather than being rebuilt per task, using a unified structural schema and an interleaved role-based training strategy to outperform task-isolated and naive multi-task baselines.

Graph Neural Networks for Databases: A Survey
Ziming Li, Youhuan Li, Yuyu Luo, Guoliang Li, Chuxu Zhang.
International Joint Conference on Artificial Intelligence (IJCAI), 2025.
paper

MatCo: Computing Match Cover of Subgraph Query over Graph Data
Zhichao Shi, Youhuan Li, Ziming Li, Yuequn Dou, Xionghu Zhong, Lei Zou.
International Conference on Management of Data (SIGMOD), 2025.
code
/
paper
(Subgraph Match Cover) We propose a new problem to compute the match cover of a subgraph query.
We define the match cover as a subset of answers such that the vertices included are exactly the same as those in the entire set.

VEND: Vertex Encoding for Edge Nonexistence Determination
Youhuan Li, Hangyu Zheng, Lei Zou, Xiaosen Li, Ziming Li, Pin Xiao, Yangyu Tao, Zheng Qin.
International Conference on Data Engineering (ICDE), 2023.
code
/
paper
(Graph Query) We propose to design vertex encoding for determinations of no-result edge queries that should not be executed.
