Data Format

Each dataset retains its original columns from LegalBench and adds an input column containing a pre-formatted prompt based on the task's instructions and template from the LegalBench registry. This input column is designed for direct use with language models. The column structure varies by task; common examples include:

  • Basic Legal: answer, index, text, input
  • Citation: answer, citation, index, text, input
  • Diversity Analysis: aic_is_met, answer, index, parties_are_diverse, text, input
  • Jurisdiction: answer, index, slice, text, input
  • SARA Analysis: answer, case id, description, index, question, statute, text, input
  • Supply Chain Disclosure: answer, index, text, input
  • MAUD Contract Analysis: answer, index, text, input

Usage

Load and use a task dataset as follows:

from datasets import load_dataset

# Load a specific task
dataset = load_dataset("DatologyAI/legalbench", "canada_tax_court_outcomes")

# Access the formatted input and answer
example = dataset["test"][0]
print("Input:", example["input"])
print("Answer:", example["answer"])

Model Evaluation Example

Evaluate a language model on a task:

from datasets import load_dataset
from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model and tokenizer
model_name = "meta-llama/Llama-2-7b-chat-hf"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Load a task
dataset = load_dataset("DatologyAI/legalbench", "personal_jurisdiction")
example = dataset["test"][0]

# Generate response
inputs = tokenizer(example["input"], return_tensors="pt")
outputs = model.generate(inputs["input_ids"], max_new_tokens=10, temperature=0.0)
response = tokenizer.decode(outputs[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True)

print(f"Gold answer: {example['answer']}")
print(f"Model response: {response}")
