Long-Context Hallucination Detection Benchmark A synthetic benchmark dataset for evaluating hallucination detection models on long documents (8K-24K tokens). This dataset is specifically designed to test models that can handle contexts beyond the typical 8K token limit. Dataset Summary Property Value Total samples 3,366 Token range 8,005 - 23,998 Average tokens 17,852 Hallucinated 1,681 (49.9%) Supported 1,685 (50.1%) Splits… See the full description on the dataset page: https://huggingface.co/datasets/vllm-sr/longcontext-haldetect.
