Dialog System Technology Challenges 8 (DSTC) Track 2 builds on the success of DSTC 7 Track 1 (NOESIS: Noetic End-to-End Response Selection Challenge). It proposes an extension of the task, incorporating new elements that are vital for the creation of a deployed task-oriented dialogue system. Specifically, three new dimensions are added to the challenge:

• Conversations with more than 2 participants
• Predicting whether a dialogue has solved the problem yet,
• Handling multiple simultaneous conversations. Each of these adds an exciting new dimension and brings the task closer to the creation of systems able to handle the complexity of real-world conversation.
• This challenge is offered with two goal oriented dialog datasets, used in 4 subtasks.
