A Novel Network for Classification of Cuneiform Tablet Metadata
By Frederik Hagelskjær - March 4, 2026
Executive Impact: Unlocking Value from Research
The immense corpus of cuneiform tablets (hundreds of thousands) vastly outstrips the number of available experts for analysis, hindering historical understanding. Traditional 2D image processing loses crucial 3D information, while current 3D methods struggle with small, annotated datasets and high-resolution point clouds.
A novel CNN-like network structure for 3D point clouds is proposed, integrating PointNet++ down-sampling with DGCNN neighbor features. This architecture is designed to handle large, high-resolution point clouds efficiently and perform well with limited training data by gradually increasing the receptive field and incorporating local and global neighbor information.
This method significantly improves the accuracy of metadata classification for cuneiform tablets, including period classification, seal presence detection, and left-side sign detection. It also successfully identifies mislabeled data, demonstrating robustness and practical utility for archaeological efforts.

Detecting Mislabeled Tablets: The 'HS 2274' Case
Our model achieved 98.5% accuracy in classifying the tablet front. In one instance, 'HS 2274' was classified as wrongly oriented. Upon comparison with the CDLI database, it was confirmed that 'HS 2274' was indeed mislabeled in the HeiCuBeDa dataset, demonstrating the model's robustness and ability to identify data errors.
- Model accuracy for tablet front detection: 98.5%
- Identified 'HS 2274' as wrongly oriented.
- Confirmed mislabeling via external database (CDLI).
100%
Accuracy achieved for seal presence detection, proving efficacy for localized feature tasks.
Future Directions: Integrating LLMs for Semantic Metadata
The current network focuses on 3D geometry. Future work could combine this method with LLM-based point cloud models (e.g., PointLLM) for text prediction and semantic metadata integration, enhancing the ability to link 3D geometry with linguistic and contextual information.
- Enhance 3D geometry with semantic context.
- Potential for text prediction and translation.
- Integrate with large language models (e.g., PointLLM).
