CorefInst: Leveraging LLMs for Multilingual Coreference Resolution (2026.tacl-1)
Copied to clipboard
| Challenge: | Existing methods for CR are encoder-only, decoder-based and asynchronous models. |
| Approach: | They propose a multilingual CR methodology which leverages decoder-only LLMs to handle overt and zero mentions. |
| Outcome: | The proposed model outperforms the leading multilingual CR model by 2 percentage points across all languages in the CorefUD v1.2 dataset. |
A Simple Unsupervised Approach for Coreference Resolution using Rule-based Weak Supervision (2022.starsem-1)
Copied to clipboard
| Challenge: | state-of-the-art coreference models rely on labeled data, but an end-to-end model is needed to solve this problem. |
| Approach: | They propose an approach that leverages an end-to-end neural model in settings where labeled data is unavailable. |
| Outcome: | The proposed approach outperforms the previous best unsupervised model and outperformed the rule-based model on English OntoNotes corpus. |
Z-coref: Thai Coreference and Zero Pronoun Resolution (2024.acl-srw)
Copied to clipboard
| Challenge: | limited research and datasets pose significant challenges in Thai language . a proposed model capable of simultaneously handling CR and ZPR tasks takes less time to train . |
| Approach: | They propose to annotate a Thai-based CR and ZPR dataset and introduce a model that can handle both tasks by adjusting the span definition to include token gaps. |
| Outcome: | The proposed model outperforms the state-of-the-art in resolving both coreference resolution and zero-pronoun resolution while taking less time to train. |
A Comprehensive Comparison of Word Embeddings in Event & Entity Coreference Resolution. (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for Coreference Resolution rely on word embeddings for word representation, but performance of different embeddables is largely overlooked. |
| Approach: | They frame their study in the context of Event and Entity Coreference Resolution (EvCR & EnCR) they examine whether there is a trade-off between performance and embedding size . |
| Outcome: | The embeddings achieve 86% of the performance of the largest model while being 1.2% of its size. |
CNER: Concept and Named Entity Recognition (2024.naacl-long)
Copied to clipboard
| Challenge: | Concept and Named Entity Recognition (CNER) is a new unified task that handles concepts and entities mentioned in unstructured texts seamlessly. |
| Approach: | They propose a new unified task that handles concepts and entities mentioned in unstructured texts seamlessly. |
| Outcome: | The proposed task gains +5.4 and +8 macro F1 points when performed as a unified task compared to specialized named entity and concept recognition systems. |
Beyond Word Boundaries: A Hebrew Coreference Benchmark and an Evaluation Protocol for Morphologically Complex Text (2026.acl-long)
Copied to clipboard
| Challenge: | CR methods originally designed for English struggle with Morphologically Rich Languages (MRLs) a single token in Hebrew may consist of multiple anaphors, and word/morpheme boundary discrepancies make mention detection and coreference resolution difficult in MRLs. |
| Approach: | They propose a CR dataset that identifies mentions at word, sub-word and multi-word levels and an evaluation protocol that directly addresses word/morpheme boundary discrepancies. |
| Outcome: | The proposed evaluation protocol directly addresses word/morpheme boundary discrepancies in Modern Hebrew, an MRL rich with complex words and pronominal clitics. |

| Challenge: | Existing supervised neural methods are underexplored for coreference resolution, especially in incremental clustering. |
| Approach: | They propose a dual-threshold incremental clustering approach based on a lightweight Transformer. |
| Outcome: | Experiments on common benchmarks show that MEIC-DT achieves highly competitive coreference performance under stringent memory constraints. |
