+# Measurement Card for HONEST
+
+## Measurement description
+The HONEST score aims to measure hurtful sentence completions in language models.
+The score uses HurtLex, a multilingual lexicon of hurtful language, to evaluate the completions.
+It aims to quantify how often sentences are completed with a hurtful word, and if there is a difference between
+groups (e.g. genders, sexual orientations, etc.).
+
+## How to use
+
+When loading the model, specify the language of the prompts and completions.
+The available languages are: 'it' (Italian), 'fr' (French), 'es' (Spanish), 'pt' (Portuguese), 'ro' (Romanian), 'en' (English).
+
+```python
+>>> honest = evaluate.load('honest', 'en')
+```
+
+Arguments:
+    **predictions** (list of list of `str`): a list of completions to [HONEST prompts](https://huggingface.co/datasets/MilaNLProc/honest)
+    **groups** (list of `str`) (*optional*): a list of the identity groups each list of completions belongs to.
+
+
+## Output values
+
+`honest_score`: the HONEST score, representing the average number of hurtful completions across all groups
+`honest_score_per_group`: the HONEST score of each group separately.
+
+### Values from popular papers
+In the [original HONEST paper](https://aclanthology.org/2021.naacl-main.191.pdf), the following scores were calculated for models, with Top K referring to the number of model completions that were evaluated:
+
+
+| Model Name       | Top K =1 | Top K =5 |Top K =20 |

+## Examples
+
+Example 1: Calculating HONEST without groups
+
+```python
+>>> honest = evaluate.load('honest', 'en')
+>>> completions = [['CEO', 'businessman', 'politician'], ['good', 'excellent', 'smart'], ['secretary', 'prostitute', 'maid'], ['beautiful', 'smart', 'tall']]
+>>> result = honest.compute(predictions=completions)
+>>> round(result['honest_score'],3)
+0.167
+```
+
+Example 2: Calculating HONEST with 2 groups (e.g. male/female)
+```python
+>>> honest = evaluate.load('honest', 'en')
+>>> completions = [['CEO', 'businessman', 'father'], ['good', 'excellent', 'smart'], ['secretary', 'prostitute', 'maid'], ['beautiful', 'smart', 'tall']]
+>>> groups = ["male", "male", "female", "female"]
+>>> result = honest.compute(predictions=completions, groups = groups)
+>>> {g:round(s,3) for g,s in result['honest_score_per_group'].items()}
+{'male': 0.0, 'female': 0.167}
+```
+
+Example 2: Calculating HONEST in another language (French)
+```python
+>>> honest = evaluate.load('honest', 'fr')
+>>> completions = [['PDG', 'avocat', 'père'], ['bon','excellent', 'intelligent'], ['secrétaire', 'prostituée', 'bonne'], ['belle', 'intelligente', 'grande']]
+>>> result = honest.compute(predictions=completions)
+>>> round(result['honest_score'],3)
+0.083
+```
