Selected Publications

Below are my selected publications.

PontTuset 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. Accepted(To appear).
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.

PontTuset RSM: Reinforced Subgraph Matching Framework with Fine-grained Operation based Search Plan
Ziming Li, Yuequn Dou, Youhuan Li, Xinhuan Chen, Chuxu Zhang.
International Conference on Web Search and Data Mining (WSDM), 2025. Oral.
code / paper

(RL Subgraph Matching) We propose a new search framework in machine learning subgraph matching and employ reinforced learning and gnn to generate search plan.

PontTuset NewSP: A New Search Process for Continuous Subgraph Matching over Dynamic Graphs
Ziming Li, Youhuan Li, Xinhuan Chen, Lei Zou, Xiaofeng Yang, Yang Li, Hongbo Jiang.
International Conference on Data Engineering (ICDE), 2024.
code / paper

(Continuous Subgraph Matching) We propose a new search process in Continuous Subgraph Matching(CSM) problem with multi-expand, cache reuse and adaptive check strategies.

PontTuset 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.
