Do UD Trees Match Mention Spans in Coreference Annotations? (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to annotate mention spans are based on delimiting token intervals, but there is no syntactic representation of the mention span. |
| Approach: | They propose to integrate coreference annotation with syntactic annotation to make them convergent in the long term. |
| Outcome: | The proposed approach could be advantageous in the long term, the authors argue. |

CorefUD 1.0: Coreference Meets Universal Dependencies (2022.lrec-1)
Copied to clipboard
| Challenge: | Recent advances in standardization for annotated language resources have led to successful large scale efforts, such as the Universal Dependencies (UD) project for multilingual syntactically annotized data. |
| Approach: | They propose a multilingual collection of corpora and a standardized format for coreference resolution compatible with morphosyntactic annotations in the UD framework. |
| Outcome: | The proposed framework is compatible with morphosyntactic annotations and includes facilities for related tasks such as named entity recognition. |
Word-Level Coreference Resolution (2021.emnlp-main)
Copied to clipboard
| Challenge: | Recent coreference resolution models rely heavily on span representations to find coreference links between word spans. |
| Approach: | They propose to consider coreference links between individual words rather than word spans and reconstruct the word span. |
| Outcome: | The proposed model outperforms existing models on the OntoNotes benchmark while being highly efficient. |
Spoken Language Treebanks in Universal Dependencies: an Overview (2022.lrec-1)
Copied to clipboard
| Challenge: | spoken language treebanks have divergent annotation schemes limiting cross-resource explorations . many spoken language trees have no written form, but many of the world languages have no spoken form at all. |
| Approach: | They propose to use the Universal Dependencies annotation scheme to annotate spoken language treebanks using a morphosyntactic annotation scheme. |
| Outcome: | The proposed treebanks differ significantly with respect to the inventory and format of transcribed phenomena and the principles adopted in their morphosyntactic annotation. |
Universal Dependencies According to BERT: Both More Specific and More General (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies show that individual BERT heads encode particular dependency relation types, but they do not match one-to-one. |
| Approach: | They propose a method for relation identification and syntactic tree construction that can be applied with minimal supervision and generalizes well across languages. |
| Outcome: | The proposed method produces significantly more consistent dependency trees than previous work and can be applied with only a minimal amount of supervision and generalizes well across languages. |
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. |
Conundrums in Event Coreference Resolution: Making Sense of the State of the Art (2021.emnlp-main)
Copied to clipboard
| Challenge: | Recent years have seen the successful application of span-based neural models to entity-based information extraction tasks such as entity coreference resolution (CR) Existing event coreference resolvers focused on feature engineering are few and far between, let alone event corefers. |
| Approach: | They propose to adapt existing span-based event reference systems to event coreference by adapting the models originally developed for entity coreference to event CR. |
| Outcome: | The proposed model improves the representations of entity mentions in entity-based IE tasks compared to non-span models . |

| Challenge: | Grammatical constructions that convey meaning through a particular combination of several morphosyntactic elements are not labeled holistically. |
| Approach: | They propose to augment UD annotations with a ‘UCxn’ annotation layer for such meaning-bearing grammatical constructions and to approach this in a typologically informed way so that morphosyntactic strategies can be compared across languages. |
| Outcome: | The proposed annotation layer could be used to annotate meaning-bearing constructions across languages and to compare them across languages. |
They Exist! Introducing Plural Mentions to Coreference Resolution and Entity Linking (C18-1)
Copied to clipboard
| Challenge: | Unlike singular mentions each of which represents one entity, plural mentions stand for multiple entities. |
| Approach: | They propose a novel coreference resolution algorithm that selectively creates clusters to handle both singular and plural mentions and a deep learning-based entity linking model that jointly handles both types of mentions through multi-task learning. |
| Outcome: | The proposed model outperforms existing models designed for singular mentions and plural mentions. |

| Challenge: | despite significant progress on entity coreference resolution, there is a general lack of understanding of what has been improved. |
| Approach: | They present an empirical analysis of entity coreference resolvers to provide an understanding of what has been improved. |
| Outcome: | The proposed model improves the performance of entity coreference resolvers. |
Arguments and Adjuncts in Universal Dependencies (C18-1)
Copied to clipboard
| Challenge: | UD attempts not to represent the argument-adjunct distinction, but is subtle, unclear, and frequently argued over. |
| Approach: | They propose a relatively conservative modification of Universal Dependencies that is free from these problems. |
| Outcome: | The proposed approach is free from the arguments and inconsistencies found in the current version of UD. |
