On Making Reading Comprehension More Comprehensive (D19-58)

Copied to clipboard

Challenge: Getting machines to "understand" text is a vast and long-standing problem, made more challenging by the fact that it is not even clear what it means to understand text.
Approach: They propose a question-based approach to machine reading comprehension that uses a natural language question to test a system's comprehension of a passage of text.
Outcome: The proposed questions have surface cues or other biases that allow a model to shortcut the intended reasoning process.
