FACTOR

This repo contains data from AI21 Labs' paper Generating Benchmarks for Factuality Evaluation of Language Models.

Data

We include the following FACTOR benchmarks for evaluating factuality of language models:

• WIKI-FACTOR: Based on the Wikipedia section of The Pile’s) validation split. The dataset consists of 2994 examples.
• NEWS-FACTOR: Based on Reuters articles extracted from The RefinedWeb Dataset. The dataset consists of 1036 examples.
• EXPERT-FACTOR: Based on the validation and test splits of ExpertQA, a long-from question answering dataset. The benchmark consists of 236 examples.

Evaluation

Setup

To install the required libraries in our repo, run:

pip install -r requirements.txt

To have a Pytorch version specific to your CUDA, install your version before running the above command.

List of Language Models

In the paper, we give the results for the following models (replace $MODEL_NAME with one of those).

• GPT-2: gpt2, gpt2-medium, gpt2-large, gpt2-xl
• GPT-Neo: EleutherAI/gpt-neo-1.3B, EleutherAI/gpt-neo-2.7B, EleutherAI/gpt-j-6B
• OPT: facebook/opt-125m, facebook/opt-350m, facebook/opt-1.3b, facebook/opt-2.7b, facebook/opt-6.7b, facebook/opt-13b, facebook/opt-30b, facebook/opt-66b

Evaluation Script

To run evaluation on models over FACTOR datasets, please use the following command:

python python eval_factuality.py \
--data_file ./data/wiki_factor.csv \
--output_folder $OUTPUT_DIR \
--model_name $MODEL_NAME
