Papers with noisy annotations
RAVEN: Robust Advertisement Video Violation Temporal Grounding via Reinforcement Reasoning (2025.acl-industry)
Copied to clipboard
| Challenge: | Existing methods for detecting ads video violations lack precise temporal grounding, noisy annotations, and limited generalization. |
| Approach: | They propose a framework that integrates curriculum reinforcement learning with large language models to enhance reasoning and cognitive capabilities for violation detection. |
| Outcome: | The proposed framework achieves superior performance in violation category accuracy and temporal interval localization. |
TEBNER: Domain Specific Named Entity Recognition with Type Expanded Boundary-aware Network (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to label data and identify entities require large amounts of manually annotated texts for training supervised models. |
| Approach: | They propose a dictionary extension method which extracts new entities through the type expanded model. |
| Outcome: | The proposed method outperforms state-of-the-art supervised systems on different types of datasets and surpasses supervised models. |
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. |
NUTMEG: Separating Signal From Noise in Annotator Disagreement (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent work suggests that annotators may have genuine disagreements, but few models separate signal from noise in annotator disagreement. |
| Approach: | They propose a Bayesian model that removes noisy annotations from training data while preserving systematic disagreements. |
| Outcome: | The proposed model outperforms models trained on NUTMEG-aggregated data. |
Distantly Supervised NER with Partial Annotation Learning and Reinforcement Learning (C18-1)
Copied to clipboard
| Challenge: | Existing approaches to named entity recognition (NER) in Chinese are limited by the lack of annotated data. |
| Approach: | They propose a method which can automatically populate annotated training data without humancost by using distant supervision. |
| Outcome: | The proposed method performs better than comparison systems on two datasets. |
SCANNER: Knowledge-Enhanced Approach for Robust Multi-modal Named Entity Recognition of Unseen Entities (2024.naacl-long)
Copied to clipboard
| Challenge: | Named entity recognition (NER) is a task to identify textual spans that correspond to named entities in the given text. |
| Approach: | They propose a model that can generalize to entities unseen during training and handle noisy annotations. |
| Outcome: | The proposed model outperforms existing methods on both MNER and GMNER benchmarks and is robust and accurate. |
Prompt-Based Monte-Carlo Tree Search for Goal-oriented Dialogue Policy Planning (2023.emnlp-main)
Copied to clipboard
| Challenge: | Optimal policy planning is a difficult task, authors say . many goal-oriented conversations require subjective strategies, they say - a problem in goal-orientated settings . |
| Approach: | They propose an approach to perform goal-oriented dialogue policy planning without model training. |
| Outcome: | The proposed approach performs goal-oriented dialogue policy planning without model training. |
Dual Debiasing for Noisy In-Context Learning for Text Generation (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing methods detect noisy annotations by ranking local perplexities, but this assumption breaks down when the noise ratio is high and many demonstrations are flawed. |
| Approach: | They propose a method that uses synthesized neighbors to explicitly correct perplexity estimates, yielding a robust Sample Cleanliness Score. |
| Outcome: | The proposed method is comparable to a fully clean demonstration corpus and performs well even with noise ratios as high as 0.8. |
USDC: A Dataset of ̲User ̲Stance and ̲Dogmatism in Long ̲Conversations (2025.findings-acl)
Copied to clipboard
| Challenge: | Previously, studies on stance and dogmatism in user conversations have focused on training models using annotated datasets at the post level, treating each post as independent and randomly sampling posts from conversation threads. |
| Approach: | They build a dataset for studying user opinion fluctuations in 764 long multi-user Reddit conversation threads, called USDC. |
| Outcome: | The proposed dataset analyzes user opinion fluctuations in 764 long multi-user Reddit conversation threads. |
