A Corpus and Cloze Evaluation for Deeper Understanding of Commonsense Stories
https://arxiv.org/pdf/1604.01696.pdf
'Story Cloze Test' (2018) is a commonsense reasoning framework for evaluating story
understanding, story generation, and script learning. This test requires a system
to choose the correct ending to a four-sentence story.

abstract = "The Story Cloze Test (SCT) is a recent framework for evaluating story comprehension and script learning. There have been a variety of models tackling the SCT so far. Although the original goal behind the SCT was to require systems to perform deep language understanding and commonsense reasoning for successful narrative understanding, some recent models could perform significantly better than the initial baselines by leveraging human-authorship biases discovered in the SCT dataset. In order to shed some light on this issue, we have performed various data analysis and analyzed a variety of top performing models presented for this task. Given the statistics we have aggregated, we have designed a new crowdsourcing scheme that creates a new SCT dataset, which overcomes some of the biases. We benchmark a few models on the new dataset and show that the top-performing model on the original SCT dataset fails to keep up its performance. Our findings further signify the importance of benchmarking NLP systems on various evolving test sets.",

TruthfulQA: Measuring How Models Mimic Human Falsehoods
https://arxiv.org/pdf/2109.07958.pdf
TruthfulQA is a benchmark to measure whether a language model is truthful in
generating answers to questions. The benchmark comprises 817 questions that
span 38 categories, including health, law, finance and politics. Questions are
crafted so that some humans would answer falsely due to a false belief or
misconception. To perform well, models must avoid generating false answers
learned from imitating human texts.
TODO: Add support for the automatic metrics, 'GPT-judge' and 'GPT-info', which
predict human evaluation of truth and informativeness (respectively) through
a fine-tuned GPT-3 model. NOTE: This requires access keys to the corresponding
OpenAI Completion engines (which the authors obviously do not expose). They do
provide the data used to fine-tune GPT-3 into `GPT-judge` and `GPT-info`, see
https://github.com/sylinrl/TruthfulQA#Fine-tuning-GPT-3-for-evaluation. Maybe
we could try this?

WinoGrande: An Adversarial Winograd Schema Challenge at Scale
https://arxiv.org/pdf/1907.10641.pdf
WinoGrande is a collection of 44k problems, inspired by Winograd Schema Challenge
(Levesque, Davis, and Morgenstern 2011), but adjusted to improve the scale and
robustness against the dataset-specific bias. Formulated as a fill-in-a-blank
task with binary options, the goal is to choose the right option for a given
sentence which requires commonsense reasoning.
NOTE: This evaluation of Winogrande uses partial evaluation as described by
Trinh & Le in Simple Method for Commonsense Reasoning (2018).

The Winograd Schema Challenge

A Winograd schema is a pair of sentences that differ in only one or two words

sentences and requires the use of world knowledge and reasoning for its resolution.
The Winograd Schema Challenge 273 is a collection of 273 such Winograd schemas.

A Wino-grad schema is a pair of sentences that differ only in one or two words and that contain a referential ambiguity that is resolved in opposite directions in the two sentences. We have compiled a collection of Winograd schemas, designed so that the correct answer is obvious to the human reader, but cannot easily be found using selectional restrictions or statistical techniques over text corpora. A contestant in the Winograd Schema Challenge is presented with a collection of one sentence from each pair, and required to achieve human-level accuracy in choosing the correct disambiguation.",
