Knowledge Graphs and Representational Models for Dialogue Systems (2025)

Abstract: I am interested graph-based dialogue management for dialogue systems, specifically the use of knowledge- graphs. Representations of knowledge combining in- formation about the world with dialogue or user-specific information, such as personal knowledge graphs (Balog and Kenter, 2019) are of particular interest to me. Knowl- edge graphs have the flexibility to represent diverse in- formation such as dialogue specific information, gen- eral world knowledge, and even situated knowledge in the case of embodied dialogue systems. Much of my previous work has investigated knowledge graphs in an HRI context that combined these attributes (Walker et al., 2022b).

## spoken dialogue system (sds) research i believe that current sds research is at an exciting juncture where many approaches to the use of large language models will be promising avenues for exploration. ## suggested topics for discussion in current sds research, i am especially interested in how multimodal systems will evolve and be applied in new scenarios. the ability of systems to learn in a multimodal space and reason over visual and spatio-temporal perceptions is an area of interest for me.
