What was the primary contribution of the Dialog State Tracking Challenge (DSTC) series to the research field?
Answer
Providing common testbeds and evaluation metrics for direct comparison.
Before the community effort surrounding the Dialog State Tracking Challenge (DSTC) series, research progress in DST was significantly hampered because different research groups tested their proposed methodologies using heterogeneous components, different domains, and varying evaluation metrics. This lack of standardization made it impossible to objectively compare advancements across different studies. The DSTCs, initiated around 2013, solved this by establishing consistent, shared testbeds and uniform evaluation metrics, thereby solidifying DST as a rigorous and comparable research problem and ultimately demonstrating the practical dominance of discriminative models.
