MOLEMAN: Mention-Only Linking of Entities with a Mention Annotation Network (2021.acl-short)
Copied to clipboard
| Challenge: | Existing approaches to entity linking represent each entity with a single vector, but instead use a contextualized mention-encoder that learns to place similar mentions of the same entity closer in vector space than mentions from different entities. |
| Approach: | They propose an instance-based nearest neighbor approach to entity linking that allows for a contextualized mention-encoder to learn to place similar mentions of the same entity closer in vector space than mentions from different entities. |
| Outcome: | The proposed approach outperforms all other systems on two multilingual benchmarks and is simpler to train and interpretable. |
Exploring Dual Encoder Architectures for Question Answering (2022.emnlp-main)
Copied to clipboard
| Challenge: | Dual encoders have been used for question-answering and information retrieval tasks with good results. |
| Approach: | They propose to use two different versions of dual encoders for QA retrieval tasks . they propose to share parameters in projection layers between two encoder towers . |
| Outcome: | The proposed architectures outperform SDE and ADE on QA retrieval tasks. |
Benchmarking Scalable Methods for Streaming Cross Document Entity Coreference (2021.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to disambiguate mentions of named entities are limited . existing approaches omit details needed to ensure fair comparisons . |
| Approach: | They propose to use streaming CDC to disambiguate mentions of named entities . they compare a set of existing and new datasets to evaluate their models . |
| Outcome: | The proposed system is well-suited for processing streams of data where new entities are frequently introduced. |
