Efficient Entity Embedding Construction from Type Knowledge for BERT (2022.findings-aacl)
Copied to clipboard
| Challenge: | Existing work has shown advantages of incorporating knowledge graphs (KGs) into BERT for various NLP tasks. |
| Approach: | They propose to integrate knowledge graphs into BERT to train entity embeddings to include rich information of factual knowledge. |
| Outcome: | The proposed models perform very well when combined with context. |
A Neural Pipeline Approach for the PharmaCoNER Shared Task using Contextual Exhaustive Models (D19-57)
Copied to clipboard
| Challenge: | NER and concept indexing perform named entity recognition and concept identifiers (CUIs) in a knowledge base. |
| Approach: | They propose a neural pipeline approach that performs named entity recognition (NER) and concept indexing (CI) they use bi-LSTM to capture the semantic information of a sequence and classify them into entities or no entities . |
| Outcome: | The proposed approach performs named entity recognition (NER) and concept indexing (CI) which links them to concept unique identifiers (CUIs) in a knowledge base. |
Jointly Learning Entity and Relation Representations for Entity Alignment (D19-1)
Copied to clipboard
| Challenge: | Entity alignment is a viable method for integrating heterogeneous knowledge among different knowledge graphs (KGs). |
| Approach: | They propose a Graph Convolutional Network-based framework for learning relation representations by embedding relation seeds into entities and incorporating relation approximation into entities to iteratively improve alignment. |
| Outcome: | The proposed approach outperforms state-of-the-art methods on three real-world cross-lingual datasets. |
Improving Entity Linking through Semantic Reinforced Entity Embeddings (2020.acl-main)
Copied to clipboard
| Challenge: | Existing entity embeddings are effective, but too distinctive for linking models to learn contextual commonality. |
| Approach: | They propose a method to inject fine-grained semantic information into entity embeddings . they use word embedds of type words to generate semantic embeddngs based on existing embeddables a sample of semantic information is injected into the embedded entities . |
| Outcome: | The proposed method reduces the distinctiveness of existing embeddings and improves performance. |
