研究领域

图计算引擎设计及优化、图数据查询和挖掘、知识图谱、自然语言问答

Weiguo Zheng has a broad interest in data management and understanding . His research focuses on graph data , such as knowledge graphs, natural language question answering, and social networks. More specifically, he is now conducting research into techniques that can make it easier to explore and query large-scale graphs. Beyond that, he is interested in the joint management and mining of neural and symbolic knowledge, aiming to deliver a comprehensive and integrated knowledge service. One significant benefit is to mitigate model illusions, promoting transparency, and facilitating knowledge updates for Large Language Models.
