Two is Better than Many? Binary Classification as an Effective Approach to Multi-Choice Question Answering (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to multi-choice question answering are based on binary classifications instead of scoring each answer as a single class. |
| Approach: | They propose a simple refactoring of multi-choice question answering tasks as a series of binary classifications and propose re-framing to make them more efficient. |
| Outcome: | The proposed approach is significantly more effective across different tasks and models. |

When Models Decide and When They Bind: A Two-Stage Computation for Multiple-Choice Question Answering (2026.findings-acl)
Copied to clipboard
| Challenge: | Multiple-choice question answering (MCQA) is easy to evaluate but adds a meta-task . prior work has shown that language models exhibit selection biases for particular option identifiers such as the label "A" |
| Approach: | They find that option-boundary residual states contain strong linearly decodable signals . winning content position becomes decoded after final option is processed . |
| Outcome: | The proposed model solves the problem and outputs the symbol that represents the answer. |
Right Answer, Wrong Score: Uncovering the Inconsistencies of LLM Evaluation in Multiple-Choice Question Answering (2025.findings-acl)
Copied to clipboard
| Challenge: | Multiple-choice question answering tasks are one of the most commonly used tasks for evaluating Large Language Models (LLMs). |
| Approach: | They analyze whether existing answer extraction methods are aligned with human judgment and how they are influenced by answer constraints in the prompt across different domains. |
| Outcome: | The proposed evaluation strategies can be inconsistent with human judgment, and can lead to inaccurate and misleading comparisons. |
What do we expect from Multiple-choice QA Systems? (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Recent work has shown that good performance on a dataset might not correlate well with human’s expectations from models that “understand” language. |
| Approach: | They propose to train a top performing multiple choice question answering model against expectations from models that "understand" language. |
| Outcome: | The proposed training paradigm leads to a model that performs on par with the original model while better satisfying our expectations. |
