Query: The SPPD System for Schema Guided Dialogue State Tracking Challenge   This paper introduces one of our group's work on the Dialog System Technology
Challenges 8 (DSTC8), the SPPD system for Schema Guided dialogue state tracking
challenge. This challenge, named as Track 4 in DSTC8, provides a brand new and
challenging dataset for developing scalable multi-domain dialogue state
tracking algorithms for real world dialogue systems. We propose a zero-shot
dialogue state tracking system for this task. The key components of the system
is a number of BERT based zero-shot NLU models that can effectively capture
semantic relations between natural language descriptions of services' schemas
and utterances from dialogue turns. We also propose some strategies to make the
system better to exploit information from longer dialogue history and to
overcome the slot carryover problem for multi-domain dialogues. The
experimental results show that the proposed system achieves a significant
improvement compared with the baseline system.
