+# UserMirrorrer-eval
+This is the evaluation set of UserMirrorer.
+
+Please refer to our paper: "Mirroring Users: Towards Building Preference-aligned User Simulator with Recommendation Feedback".
+
+## Notice
+
+In the `UserMirrorer` dataset, the raw data from `MIND` and `MovieLens-1M` datasets are distributed under restrictive licenses and cannot
+be included directly.
+
+Therefore, we provide a comprehensive, step-by-step pipeline to load the original archives, execute all necessary preprocessing
+operations, and assemble the final UserMirrorer training and test splits.
+
+Click [here](https://colab.research.google.com/github/UserMirrorer/UserMirrorer/blob/main/UserMirrorer_GetFullDataset.ipynb) to run the script notebook on Google Colab to get the full dataset. Also, you can download it and run it locally.
