# Addressing Objects and Their Relations: The Conversational Entity Dialogue Model

## TL;DR

This paper introduces a novel dialogue model centered on entities and their relations, enhancing the ability of spoken dialogue systems to handle complex structures and improve response quality.

## Contribution

The work presents a new entity-centric dialogue model capable of modeling relations and multiple entities, outperforming baseline systems in relation handling and response generation.

## Key findings

- Relation modeling improves dialogue system performance
- The model effectively processes and addresses user-input relations
- Trained policies using relations outperform baselines

## Abstract

Statistical spoken dialogue systems usually rely on a single- or multi-domain dialogue model that is restricted in its capabilities of modelling complex dialogue structures, e.g., relations. In this work, we propose a novel dialogue model that is centred around entities and is able to model relations as well as multiple entities of the same type. We demonstrate in a prototype implementation benefits of relation modelling on the dialogue level and show that a trained policy using these relations outperforms the multi-domain baseline. Furthermore, we show that by modelling the relations on the dialogue level, the system is capable of processing relations present in the user input and even learns to address them in the system response.
