+# OpenScan
+
+OpenScan is a benchmark for generalized open-vocabulary 3D scene understanding. It extends ScanNet200-style scene understanding with eight object-attribute aspects: material, affordance, property, type, manner, synonyms, requirement, and element.
+
+This dataset mirror contains the OpenScan validation annotations and evaluation ground-truth files for the AAAI 2026 paper.
+
+## Files
+
+| File | Description |
+| --- | --- |
+| `openscan_val_raw.json` | Raw validation annotations with one record per scene object. |
+| `openscan_label_mapping/` | Expanded TSV label mappings for all eight OpenScan aspects. |
+| `openscan_label_mapping.zip` | Archive of the label mapping files. |
+| `openscan_val_gt.zip` | Processed validation ground-truth files for evaluation. |
+
+The raw validation JSON contains 10,388 annotated objects from 312 validation scenes. The processed ground truth contains 312 scene files for each of the eight OpenScan aspects.
+
+## Annotation Format
+
+Each raw annotation record has this structure:
+
+```json
+{
+  "scene_id": "scene0011_00",
+  "object_id": "0",
+  "object_name": "floor",
+  "material": "stone",
+  "affordance": "stand",
+  "property": "other",
+  "type": "land",
+  "manner": "other",
+  "synonyms": "other",
+  "requirement": "other",
+  "element": "other"
+}
+```
+
+## Usage
+
+Load the raw validation annotation table with `datasets`:
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset(
+    "json",
+    data_files="hf://datasets/garrying/OpenScan/openscan_val_raw.json",
+    split="train",
+)
+```
+
+Download the processed validation ground truth for evaluation:
+
+```bash
+hf download garrying/OpenScan openscan_val_gt.zip --repo-type dataset --local-dir .
+unzip openscan_val_gt.zip
+```
+
+The extracted `openscan_val_gt/` directory contains:
+
+```text
+gt_affordance/
+gt_element/
+gt_manner/
+gt_material/
+gt_property/
+gt_requirement/
+gt_synonyms/
+gt_type/
+```
