# Dataset Card for LongbenchSeg

<!-- Provide a quick summary of the dataset. -->

The segmented version of [Longbench](https://huggingface.co/datasets/zai-org/LongBench) using the trained [segmenter](https://huggingface.co/Syon-Li/Qwen3-4B-Instruct-2507-Segmenter) from the paper [Towards Generalization of Block Attention via Automatic Segmentation and Block Distillation](https://arxiv.org/abs/2605.15913). 

We set the recursion depth to 1 and use the threshold value of 0.4.

## Dataset Details
