Some tasks are inferred based on the benchmarks list.
The benchmarks section lists all benchmarks using a given dataset or any of
its variants. We use variants to distinguish between results evaluated on
slightly different versions of the same dataset. For example, ImageNet 32⨉32
and ImageNet 64⨉64 are variants of the ImageNet dataset.
CMRC 2018 is a dataset for Chinese Machine Reading Comprehension. Specifically, it is a span-extraction reading comprehension dataset that is similar to SQuAD.
