Papers with sequence tagging models
Recognizing Complex Entity Mentions: A Review and Future Directions (P18-3)
Copied to clipboard
| Challenge: | Named entity recognition (NER) is a task of identifying and classifying named entities (NE) within text. |
| Approach: | They review existing methods for identifying and classifying named entities within text . they identify the research gap and propose a new approach to tackle these problems . |
| Outcome: | The proposed methods address the identified identified gaps in the literature and provide recommendations for future work. |
Generative Models for Product Attribute Extraction (2023.emnlp-industry)
Copied to clipboard
| Challenge: | generative models are used for product attribute extraction, a new field in information extraction and e-commerce. |
| Approach: | They analyze generative models for product attribute extraction and demonstrate their utility . they perform experiments on Amazon and MAVE product attribute datasets . |
| Outcome: | The proposed model can generate implicit attribute values, which state-of-the-art models are unable to extract. |
Influence Functions for Sequence Tagging Models (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Named Entity Recognition, Part-of-Speech tagging, and Semantic Role Labeling are standard tasks in NLP, but there has been little work on interpretability methods for sequence taging. |
| Approach: | They propose to extend influence functions to sequence tagging tasks by identifying noisy annotations in NER corpora. |
| Outcome: | The proposed methods are able to identify noisy annotations in NER corpora and are scalable. |
Syntactic Patterns Improve Information Extraction for Medical Search (N18-2)
Copied to clipboard
| Challenge: | Medical professionals search the literature by specifying the type of patients, the medical intervention(s) and the outcome measure(s). |
| Approach: | They propose to exploit the availability of structured abstracts to extract medically relevant information from syntactic patterns. |
| Outcome: | The proposed models differ from the constituent unigrams in the extracted patterns, suggesting that they capture contextual information that is otherwise lost. |
End-to-End Sequential Metaphor Identification Inspired by Linguistic Theories (P19-1)
Copied to clipboard
| Challenge: | Existing sequence tagging models do not explicitly exploit linguistic theories of metaphor identification. |
| Approach: | They propose to exploit linguistic theories of metaphor identification in deep neural networks to improve model performance. |
| Outcome: | The proposed models achieve state-of-the-art in end-to-end metaphor identification on three datasets. |
Coupling Global and Local Context for Unsupervised Aspect Extraction (D19-1)
Copied to clipboard
| Challenge: | Existing studies on aspect extraction focus on sequence tagging models trained on human-annotated data. |
| Approach: | They propose a novel neural model capable of coupling global and local representations to discover aspect words by combining global and locale contexts. |
| Outcome: | The proposed model outperforms state-of-the-art models on laptop and restaurant reviews on two benchmarks. |
Targeted Syntactic Evaluation for Grammatical Error Correction (2025.acl-long)
Copied to clipboard
| Challenge: | Existing evaluation datasets based on learner-produced texts are insufficient for evaluating models . Currently, sequence-to-sequence models and sequence tagging models perform well on beginner-level grammar items . |
| Approach: | They propose a new evaluation paradigm that assesses GEC models using minimal pairs of ungrammatical and grammatically paired sentences for each grammar item. |
| Outcome: | The proposed evaluation paradigm assesses models using minimal pairs of ungrammatical and grammatically-spaced sentences for each grammar item. |
