Outline

This paper presents HierTOD, a hierarchical, goal-based task-oriented dialog system that supports complex tasks in enterprise environments. Unlike existing TOD systems with a single-layer workflow structure, HierTOD utilizes hierarchical goals to support complex workflows. It provides efficient task support through components such as natural language understanding, complex goal retrieval, dialogue management, and response generation, as well as data services equipped with a domain knowledge base and search engine. It integrates two TOD paradigms: slot filling and step-by-step guidance. The effectiveness and usability of HierTOD were verified through user research.

Takeaways, Limitations

Takeaways:
We present a novel approach to designing complex task-oriented conversational systems in enterprise environments.
Achieve efficient task support and improved user experience through a hierarchical, goal-based TOD system.
By integrating two TOD paradigms - slot filling and step-by-step guidance - we have increased adaptability to different task types.
Integrating domain knowledge bases and search engines has improved the efficiency of utilizing domain-specific knowledge.
Limitations:
Detailed information about the scale and participant composition of the user study presented in this paper is lacking.
Further research is needed on the scalability of the HierTOD system and its applicability to various domains.
Dependence on a specific domain may make generalization to other domains difficult.
There is a lack of detailed description of the system's error handling and response strategies for exception situations.
