CDR-Dataset

Contextual Default Retraction Dataset

A dataset for evaluating contextual default reasoning and belief retraction in language models.

Release: v1. Teacher-generated references, not independently verified ground truth.

Available splits: train, test, revision_1, and revision_2. Records use query/context/entity fields and string true/false labels.

from datasets import load_dataset
train = load_dataset("leo-bjpark/CDR-Dataset", "v1", split="train")
test = load_dataset("leo-bjpark/CDR-Dataset", "v1", split="test")

See release notes, statistics, and evaluation.

Generation code: https://github.com/leobumjin/CDR-Dataset The manifest pins the matching pipeline files with SHA-256 hashes.
