 This is an informal implementation of the model focusing on the link prediction task [Inductive Entity Representations from Text via Link Prediction](https://arxiv.org/abs/2010.03496) which is mainly an ablation study of [KEPLER: A Unified Model for Knowledge Embedding and Pre-trained Language Representation](https://arxiv.org/abs/1911.06136). This tool is based on the library [MKB](https://github.com/raphaelsty/mkb). CKB is designed to be compatible with HuggingFace's models.
