Abstract

Artificial intelligence (AI) has been transforming the way we interact with the world. Neural symbolic AI has emerged in recent years, promises more explainable, trustworthy, and versatile AI systems. The integration of symbolic knowledge and neural models is crucial for unleashing the full potential of neural-symbolic reasoning. Knowledge graphs, as a structured representation of knowledge that captures relationships between entities, provide a powerful tool for organizing real world information. In this talk, I will share my research which lies in knowledge graph reasoning and its applications, using both the traditional symbolic reasoning and neural reasoning methods and more importantly the intersection between the two. Different from previous research on knowledge graph reasoning which has primarily concentrated on reasoning for fixed and precise input queries, my goal is to enhance understanding and utilization of input queries, addressing the oversight of ambiguity and dynamism in previous research. By accurately modeling ambiguous and dynamic input queries, the research aims to exponentially advance the complexity, scale, and reasoning power of knowledge graph reasoning models, crucial for tackling real-world challenges. Towards the end of my talk, I will share my vision for the future work.
