+# UniRank: Benchmarking Ranking Models for Unified Sequential Modeling and Feature Interaction
+
+This repository contains preprocessed datasets for **UniRank**, an open benchmark for evaluating ranking models that unify sequential modeling and feature interaction in recommender systems.

+
+## Overview
+
+UniRank standardizes chronological point-wise autoregressive supervision, multi-feedback evaluation, model implementations, data processing, and distributed training in one reproducible pipeline.
+
+The benchmark contains fifteen unified ranking architectures and five industrial datasets from short-video, advertising, and e-commerce scenarios.
+
+## Dataset Statistics
+
+The benchmark evaluates unified ranking models on five large-scale public datasets spanning short-video, advertising, and e-commerce platforms:
+
+| Dataset | Instances | Users | Items | Fields | Tasks | Avg. length | Max. length |
+|:--|--:|--:|--:|--:|--:|--:|--:|
+| QK-Video | 493,306,303 | 4,996,176 | 3,752,235 | 10 | 4 | 99 | 6,013 |
+| KuaiRand | 323,464,444 | 27,285 | 32,038,725 | 40 | 6 | 11,855 | 228,030 |
+| TAAC-25 | 757,207,146 | 7,706,778 | 15,707,425 | 30 | 2 | 98 | 100 |
+| Taobao | 23,601,301 | 470,570 | 831,643 | 23 | 4 | 50 | 3,756 |
+| MerRec | 172,304,959 | 1,697,072 | 42,577,610 | 20 | 5 | 102 | 26,576 |

+## Quick Start (Download)
+
+You can download any of the preprocessed datasets using the Hugging Face CLI:
+
+```bash
+pip install huggingface_hub
+
+# Example: Downloading KuaiRand dataset
+huggingface-cli download salmon1802/KuaiRand \
+  --repo-type dataset \
+  --local-dir /path/to/data/KuaiRand_Video_Action
+```
+
+Please update your local paths in `config/dataset_config.yaml` as described in the [GitHub Repository](https://github.com/salmon1802/UniRank).
