| Challenge: | Current models for cross-document co-reference resolution assume that all documents are of the same type or fall under the same theme. |
| Approach: | They propose a task for cross-document cross-domain co-reference resolution (CD2CR) task aims to identify links between entities across heterogeneous document types. |
| Outcome: | The proposed task outperforms current state-of-the-art models on CD2CR in cross-domain, cross-document setting. |

Revisiting Joint Modeling of Cross-document Entity and Event Coreference Resolution (P19-1)
Copied to clipboard
| Challenge: | Recognizing that various textual spans across multiple texts refer to the same entity or event is an important NLP task. |
| Approach: | They propose a neural architecture for cross-document coreference resolution by representing an event mention using its lexical span, surrounding context, and relation to other mentions via predicate-arguments structures. |
| Outcome: | The proposed model outperforms the state-of-the-art event coreference model on ECB+ while providing the first entity coreference results on this corpus. |

Bridging Resolution: A Survey of the State of the Art (2020.coling-main)
Copied to clipboard
| Challenge: | bridging resolution is an anaphora resolution task that is less studied than entity coreference resolution. |
| Approach: | This paper presents a survey of the current state of research on bridging resolution . it identifies and resolves bridling/associative anaphors, which are anamorphic references to non-identical associated antecedents. |
| Outcome: | The proposed task is more difficult than entity coreference resolution because of the lack of annotated corpora and lack of standardized evaluation protocols. |

Copied to clipboard
| Challenge: | Existing word embedding models generate word representations by running long short-term memory recurrent neural networks on each sentence of an input article or conversation separately. |
| Approach: | They propose a word embedding model that learns cross-sentence dependency . they use linear sentence linking and attentional sentence linking to learn cross-entry dependency based on context sentences . |
| Outcome: | The proposed model improves end-to-end co-reference resolution by taking knowledge from context sentences and the entire document. |
