+# CoRoleHOI Dataset
+
+## Overview
+
+**CoRoleHOI** is a dataset for **role-asymmetric multi-person multi-object Human–Object Interaction (HOI)**.
+
+It is designed to support research in:
+- Text-driven motion generation
+- Multi-person interaction modeling
+- Human-object interaction understanding
+- Embodied AI and robotics
+
+The dataset integrates multi-modal signals:
+- SMPL-X human motion sequences
+- Object trajectories (4×4 transformation matrices)
+- Fine-grained contact annotations
+- Structured textual prompts
+- Object meshes and SDF representations
+
+---
+
+## Key Contributions
+
+- Role-asymmetric interaction modeling (e.g., giver → receiver)
+- Multi-person coordination scenarios
+- Multi-object interaction support
+- Fine-grained contact supervision
+- Aligned text–motion–object representation
+
+---

+## Text Annotations
+
+The dataset provides structured language supervision:
+
+- augmented_prompts.json  
+  Multiple paraphrases per interaction
+
+- prompt_dict.json  
+  Prompt ID to canonical text mapping
+
+- split_prompts.json  
+  Train / validation / test splits
