| Challenge: | Systematically organizing and geotagging large amounts of crowdsourced information requires substantial manual effort, often led by volunteers. |
| Approach: | They present a dataset of 14k citizen reports related to the 2022 Kenyan General Election . they investigate whether language models can assist in scalably categorizing and geotagging reports . |
| Outcome: | The proposed dataset aims to show whether language models can assist in categorizing and geotagging reports, thus highlighting its potential application in the AI for Social Good space. |

| Challenge: | Existing benchmarks measure the correlation with human judgements of faithfulness on model-generated summaries, but they are insufficient for diagnosing whether metrics are consistent, effective on human-written texts, and sensitive to different error types. |
| Approach: | They propose to use unfaithful minimal pairs to measure the consistency of automatic faithfulness metrics by comparing human-written summary pairs with a dataset of 889 human-writing, minimally different summary pairs. |
| Outcome: | The proposed benchmarks show that the most discriminative metrics tend not to be the most consistent, and that the best performing metrics are sensitive to errors. |
Impact of Pretraining Term Frequencies on Few-Shot Numerical Reasoning (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Pretrained language models have demonstrated ability to perform numerical reasoning by extrapolating from a few examples in few-shot settings. |
| Approach: | They investigate how well pretrained language models reason with terms less frequent in pretraining data. |
| Outcome: | The models are more accurate on instances whose terms are more prevalent, in some cases above 70% more accurate than the bottom 10%. |
Multi-View Source Ablation for Faithful Summarization (2023.findings-eacl)
Copied to clipboard
| Challenge: | MuFaSSa is a metric for evaluating faithfulness of abstractive summaries . it uses different strategies to remove information from source document to form multiple ablated views . |
| Approach: | They propose a metric for evaluating faithfulness of abstractive summaries using multiple ablated views. |
| Outcome: | The proposed metric outperforms existing models on summarization tasks and human-annotated faithfulness labels. |

| Challenge: | Recent language model prompting methods can achieve high accuracy in zero- and few-shot settings while requiring few to no learned task-specific parameters. |
| Approach: | They propose to use a dedicated pretraining stage to improve promptability in zero-shot settings and few-shot tuning. |
| Outcome: | The proposed method improves promptability in zero- and few-shot settings, while the existing method yields subpar performance. |
Benchmarking Scalable Methods for Streaming Cross Document Entity Coreference (2021.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to disambiguate mentions of named entities are limited . existing approaches omit details needed to ensure fair comparisons . |
| Approach: | They propose to use streaming CDC to disambiguate mentions of named entities . they compare a set of existing and new datasets to evaluate their models . |
| Outcome: | The proposed system is well-suited for processing streams of data where new entities are frequently introduced. |
