Hi,
the dataset will be fully released at the conference when the dataset paper will be published and the dataset will be made available for public download long term.
However, if you wish to use the dataset in a paper that has an earlier deadline then please message me privately and we can see what we can work out. Maybe we can make a reference to a pre-print or forthcoming version of the dataset paper, I am not sure what the solution will be, but if you can email me the deadline you are working towards we can try to find a solution.
Cheers,
Nick
