What is the task schema?

We introduce the concept of task schema that defines the format of datasets belonging to this task. This is useful to standardize the formats of datasets from the same task. For example, the schema of text classification task is:

• text:str
• label:ClassLabel

while for text-matching task, its schema can be defined as:

• text1:str
• text2:str
• label:ClassLabel

More detailed can refer to this folder.

Also, this doc details how to add a new task schema.
