Symbolic Dialouge for General Domain State Tracking

Abstract

Task-oriented dialogue (TOD) is a system that helps users achieve their goals. While the task is reviewed and improved regularly, a formal system for industrial standards has not yet been established. Dialogue state tracking is a sub-task that involves predicting current dialogue slot values given the conversation and in some cases, the slots that are being required or informed. Based on a well-documented schema with instructions for possible slots and intents along with their descriptions, schema-guided TOD exploits a concrete set of guidelines to add extra context and perform general zero-shot ability on state tracking.
