# Bias in Bios

Bias in Bios was created by (De-Artega et al., 2019) and published under the MIT license (https://github.com/microsoft/biosbias). The dataset is used to investigate bias in NLP models. It consists of textual biographies used to predict professional occupations, the sensitive attribute is the gender (binary). 

The version shared here is the version proposed by (Ravgofel et al., 2020) which slightly smaller due to the unavailability of 5,557 biographies. 

The dataset is divided between train (257,000 samples), test (99,000 samples) and dev (40,000 samples) sets.

To load each all splits ('train', 'dev', 'test'), use the following code :
```python 
train_dataset = load_dataset("LabHC/bias_in_bios", split='train')
test_dataset = load_dataset("LabHC/bias_in_bios", split='test')
dev_dataset = load_dataset("LabHC/bias_in_bios", split='dev')
```

Below are presented the classifiaction and sensitive attribtues labels and their proportion. Distributions are similar through the three sets.
