A Broad-Coverage Challenge Corpus for Sentence Understanding through Inference (N18-1)
Copied to clipboard
| Challenge: | et al., 1996, show that many of the most actively studied problems in NLP depend in large part on natural language understanding (NLU). |
| Approach: | They propose a dataset for machine learning that uses ten different genres of English to evaluate sentences for their meanings. |
| Outcome: | The multi-genre natural language inference corpus is one of the largest available for natural language understanding. |

| Challenge: | Many datasets for training and evaluating natural language understanding (NLU) models contain systematic artifacts that are identified only after data collection is complete. |
| Approach: | They propose to have linguists identify artifacts and gaps in the data and communicate with non-expert crowdworkers to adjust task instructions and incentives. |
| Outcome: | The proposed protocol does not increase accuracy on out-of-domain test sets, and adds a chatroom does not. |

What Makes Reading Comprehension Questions Difficult? (2022.acl-long)
Copied to clipboard
| Challenge: | a recent study shows that natural language understanding benchmarks are not able to measure future progress . a crowdsourcing approach is needed to collect diverse examples without sacrificing diversity or coverage. |

| Outcome: | The results show that passage source, length, and readability measures do not significantly affect question difficulty. |

| Challenge: | Getting sociological beliefs wrong can slow research and lead to wasted effort, missed opportunities, and needless fights. |
| Approach: | They present the results of the NLP Community Metasurvey, run from May to June 2022. |
| Outcome: | The NLP community metasurvey elicited opinions on controversial issues from May to June 2022. |
What Ingredients Make for an Effective Crowdsourcing Protocol for Difficult NLU Data Collection Tasks? (2021.acl-long)
Copied to clipboard
| Challenge: | Despite the importance of datasets for natural language understanding, there has been little attention on crowdsourcing methods for collecting datasets. |
| Approach: | They compare the effectiveness of crowdsourcing methods for boosting NLU example difficulty with training crowdworkers instead of expert judgments. |
| Outcome: | The proposed method is ineffective for boosting NLU example difficulty, but it is not effective for training crowdworkers and qualifying workers based on expert judgments. |

| Challenge: | Latent structure models are a powerful tool for compositional data modeling and pipelines. |
| Approach: | This tutorial will cover recent advances in discrete latent structure models . it will discuss their motivation, potential, and limitations . |
| Outcome: | This tutorial will cover recent advances in discrete latent structure models . it will discuss their motivation, potential, and limitations . |
CrowS-Pairs: A Challenge Dataset for Measuring Social Biases in Masked Language Models (2020.emnlp-main)
Copied to clipboard
| Challenge: | Pretrained language models use cultural biases implicitly, causing harm . identifying and quantifying learnt biase enables us to measure progress . |
| Approach: | They propose a benchmark to measure social bias in pretrained language models . they use 1508 examples that cover stereotypes dealing with nine types of bias . |
| Outcome: | The proposed benchmark focuses on stereotypes about historically disadvantaged groups and contrasts them with advantaged groups. |

| Challenge: | Existing models for natural language understanding are limited to processing only a few hundred words at a time. |
| Approach: | They propose a dataset with context passages in English that have an average length of 5,000 tokens. |
| Outcome: | a new dataset with long-text comprehension questions is used to test models on long-document comprehension . the questions are validated by contributors who have read the entire passage, not just excerpts . only half of the questions can be answered by annotators working under tight time constraints . |
Human vs. Muppet: A Conservative Estimate of Human Performance on the GLUE Benchmark (P19-1)
Copied to clipboard
| Challenge: | GLUE is a suite of language understanding tasks that has seen dramatic progress in the past year . average performance on the benchmark is 83.9, state of the art at the time of writing . |
| Approach: | They use crowdsourcing to measure human performance on a set of language understanding tasks and 20 examples to determine whether there is room for improvement. |
| Outcome: | The GLUE benchmark outperforms state-of-the-art models on six of the nine tasks and achieves an average score of 87.1. |

| Challenge: | NLP models learn social biases, but little work has been done on how these biase manifest in outputs for applied tasks like question answering (QA). |
| Approach: | They propose a dataset that highlights attested social biases against people belonging to protected classes along nine social dimensions relevant for U.S. English-speaking contexts. |
| Outcome: | The proposed dataset highlights attested social biases against people belonging to protected classes along nine social dimensions relevant for U.S. English-speaking contexts. |

| Challenge: | High agreement is often used to show reliability of annotation procedures, but it is insufficient to ensure or reproducibility. |
| Approach: | They propose a protocol that increases Inter-Annotator Agreement among annotators and a standardized and codified protocol that strictly enforces transparency in the annotation process. |
| Outcome: | The proposed protocol ensures transparency in the annotation process, which ensures reproducibility of annotation guidelines. |
