- New submission deadline: Oct. 15th

The official submission site had problems to upload files. The problems were fixed now. Let us extend the submission deadline to * Oct. 15th *

- Submission site

Now the submission site is open.

  The data format is the same as test_set4DSTC7-AVSD.json.
  Please replace __UNDISCLOSED__ with your generated answers.

- New baseline system

Please go to the following link to get the new baseline system:

- Data use policy

  1. Registrant will submit system results and system description papers: 
     Publish results anywhere as DSTC7 participants
  2. Registrant will not submit results or system description papers:
     Please wait using the data until it will be publicly available
  3. Others:
     Currently, you cannot access the data.
     Please wait until the data will be open.

- Official data set is released

*DSTC7 is ongoing and the data is not publicly available now.

The data format of the output should be the same as the given test set file in the shared directory:


The original videos of the test sets of the official Charades Challenge

Please fill your answers into __UNDISCLOSED__ below:

  "dialog" : [
                 "answer" : "no and it is a window that he is standing in front of .",
                 "question" : "hello . did someone come to the door ?"
                 "answer" : "__UNDISCLOSED__",
                 "question" : "is he looking at something outside the window ?"

- Track Description

Welcome to the Audio Visual Scene-Aware Dialog (AVSD) challenge and dataset. This challenge is one track of the 7th Dialog System Technology Challenges (DSTC7) workshop. The task is to build a system that generates responses in a dialog about an input video.

- Tasks

In this challenge, the system must generate responses to a user input in the context of a given dialog.
This context consists of a dialog history (previous utterances by both user and system) in addition to video and audio information that comprise the scene. The quality of a system’s automatically generated sentences is evaluated using objective measures to determine whether or not the generated responses are natural and informative.

1. Task 1: Video and Text

a. Use the video and text training data provided but no external data sources, 
   other than publicly available pre-trained feature extraction models.

   There are two options: with or without using the summary generated by the questioners after holding 10 QAs.

b. External data may also be used for training.

2. Task 2: Text Only

a. Do not use the input videos for training or testing. 
   Use only the text training data (dialogs and video descriptions) provided. 
b. Any publicly available text data may also be used for training.

- Dataset

Proto type data set:

Training Validation Test
# of Dialogs 6172 732 733
# of Turns 123,480 14,680 14,660
# of Words 1,163,969 138,314 138,790
  The training data is part of the training data.
  The validation data is half of the officila validation data.
  The test data is the rest of the official validation data.

Official data set:

The number of tunrs for the test set is smaller than the validation because they are not always full dialogs.

Training Validation Test
# of Dialogs 7,659 1,787 1,710
# of Turns 153,180 35,740 13,490
# of Words 1,450,754 339,006 110,252
