| Challenge: | Entity linking methods based on dense retrieval are often not efficient in large-scale applications as they are sensitive to the structure of the embedding space. |
| Approach: | They propose a method to infuse structural information into the space of entity representations by using prior knowledge of entity types. |
| Outcome: | The proposed method outperforms other type-aware approaches and matches generative models with 18 times more parameters. |

E-BERT: Efficient-Yet-Effective Entity Embeddings for BERT (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to enhance BERT with factual knowledge about entities require no additional pretraining and no changes to the encoder itself. |
| Approach: | They propose a way to inject factual knowledge into the pretrained BERT model by aligning Wikipedia2Vec entity vectors with BERT's native wordpiece vector space and feeding the aligned entity vector into BERT as if they were wordpieces. |
| Outcome: | The proposed version outperforms baseline models on unsupervised question answering, supervised relation classification and entity linking tasks. |

Modeling Fine-Grained Entity Types with Box Embeddings (2021.acl-long)
Copied to clipboard
| Challenge: | Neural entity typing models typically represent fine-grained entity types as vectors in a high-dimensional space, but such spaces are not well-suited to modeling complex interdependencies. |
| Approach: | They propose to use box embeddings to embed types into a high-dimensional hyperrectangle space and then use it to hypothesize a type representation for the mention. |
| Outcome: | The proposed model captures latent type hierarchies better than a vector-based model on several entity typing benchmarks. |

Fine-Grained Evaluation for Entity Linking (D19-1)
Copied to clipboard
| Challenge: | Entity Linking (EL) is an Information Extraction task that identifies entity mentions in a text corpus and associates them with an unambiguous identifier in KBs such as Wikipedia, BabelNet, DBpedia, Wikidata and YAGO. |
| Approach: | They propose a fine-grained categorization of different types of entity mentions and links and propose 'fuzzy recall' metric to address the lack of consensus and compare a selection of online EL systems. |
| Outcome: | The proposed task offers a bridge between unstructured text and structured KBs, where EL has applications for semantic search, document classification, relation extraction, and more. |
