Call for participation

DIALOGUE BREAKDOWN DETECTION CHALLENGE 4 (DBDC4)
https://sites.google.com/site/dialoguebreakdowndetection4/

Following the success of DBDC3, we are please to organize DBDC4 as
part of the WOCHAT workshop held in Sicily in conjunction with
IWSDS2019 (https://iwsds2019.unikore.it/).

The task of dialogue breakdown detection is to detect whether the
system utterance causes dialogue breakdown (a situation in a dialogue
where users cannot proceed with the conversation) in a given dialogue
context. The participants of this challenge will develop a dialogue
breakdown detector that outputs a dialogue breakdown label (B:
breakdown, PB: possible breakdown, or NB:Not a breakdown) and a
distribution of these labels.

Although we acknowledge that the schedule can be rather tight, we
consider DBDC4 to be a perfect opportunity for you to test your
dialogue models, especially in terms of contextual understanding
and natural human-computer communication.

*Schedule:

-January 29: Announcement of the challenge
-Jan 29-March 31: Registration period
  Registration can be done at: https://goo.gl/forms/p0av6p6k8d3D0oWB3
