YARBUS : Yet Another Rule Based belief Update System
This work addresses belief tracking for dialog systems, but it is incremental as it builds on existing challenges with a simpler approach.
The authors tackled belief tracking in dialog systems with a simple rule-based system, achieving favorable rankings on the second and third Dialog State Tracking challenges, which prompted a reevaluation of more complex previous methods.
We introduce a new rule based system for belief tracking in dialog systems. Despite the simplicity of the rules being considered, the proposed belief tracker ranks favourably compared to the previous submissions on the second and third Dialog State Tracking challenges. The results of this simple tracker allows to reconsider the performances of previous submissions using more elaborate techniques.
