-DROP: A Reading Comprehension Benchmark Requiring Discrete Reasoning Over Paragraphs.
-. DROP is a crowdsourced, adversarially-created, 96k-question benchmark, in which a system must resolve references in a
-question, perhaps to multiple input positions, and perform discrete operations over them (such as addition, counting, or
- sorting). These operations require a much more comprehensive understanding of the content of paragraphs than what was
- necessary for prior datasets.
