• Authors: Xanh Ho, Johannes Mario Meissner, Saku Sugawara, and Akiko Aizawa
• Abstract summary: We focus on the field of machine reading comprehension (MRC), an important task for showcasing high-level language understanding. We highlight two concerns for shortcut mitigation in MRC: (1) the lack of public challenge sets, a necessary component for effective and reusable evaluation, and (2) the lack of certain mitigation techniques that are prominent in other areas.

• Abstract: The issue of shortcut learning is widely known in NLP and has been an important research focus in recent years. Unintended correlations in the data enable models to easily solve tasks that were meant to exhibit advanced language understanding and reasoning capabilities. In this survey paper, we focus on the field of machine reading comprehension (MRC), an important task for showcasing high-level language understanding that also suffers from a range of shortcuts. We summarize the available techniques for measuring and mitigating shortcuts and conclude with suggestions for further progress in shortcut research. Importantly, we highlight two concerns for shortcut mitigation in MRC: (1) the lack of public challenge sets, a necessary component for effective and reusable evaluation, and (2) the lack of certain mitigation techniques that are prominent in other areas.

  Clever Hans behavior, spurious correlations, or confounders, present a significant challenge in machine learning and AI. Research in this area remains fragmented across various terminologies, hindering the progress of the field as a whole. We introduce a unifying taxonomy by providing a formal definition of shortcuts and bridging the diverse terms used in the literature.

  We propose a two-stage framework for NKI tasks, named PGRA. In the first stage, we adopt a task-agnostic retriever to build a shared static index and select candidate evidence efficiently. In the second stage, we design a prompt-guided reranker to rerank the nearest evidence according to task-specific relevance for the reader.

  We argue that larger proportion of shortcut questions in training data make models rely on shortcut tricks excessively. A thorough empirical analysis shows that MRC models tend to learn shortcut questions earlier than challenging questions.

  Machine reading comprehension (MRC) is an AI challenge that requires machine to determine the correct answers to questions based on a given passage. When unanswerable questions are involved in the MRC task, an essential verification module called verifier is especially required in addition to the encoder. This paper devotes itself to exploring better verifier design for the MRC task with unanswerable questions.
