Copied to clipboard
| Challenge: | Developing NLP methods for historical corpora is difficult, as only domain experts can label them . off-the-shelf models are trained on modern language texts, rendering them weaker for historical documents . |
| Approach: | They propose to use an annotated newspaper dataset to extract historical data from a novel domain of texts. |
| Outcome: | The proposed method performs well on a multilingual dataset in English, French, and Dutch . it is possible to extract surprisingly good results even with scarce annotated data using existing models and datasets for modern languages . |

| Challenge: | digitised historical documents suffer from errors introduced by optical character recognition (OCR) and are written in an archaic language. |
| Approach: | They investigate the continuities and transformations of bias in Caribbean historical newspapers during the colonial era . they use distributional semantics models and word embeddings to measure gender, race, and intersectional biases. |
| Outcome: | The authors show that gender and racial biases are interdependent and their intersection triggers distinct effects. |

| Challenge: | Historical newspapers from the colonial period offer valuable evidence of how racializing language evolved over time. |
| Approach: | They propose a contextual question answering and visual question answering task from colonial newspapers . they propose linguistic training for temporal word embedding with a compass to study racialization . |
| Outcome: | The proposed tasks are limited for low-resource tasks, the authors show . the authors compare the results of two QA pairs from colonial newspapers to a compass . |
