Prototype-Guided Pseudo Labeling for Semi-Supervised Text Classification (2023.acl-long)
Copied to clipboard
| Challenge: | Existing semi-supervised text classification methods suffer from categorical boundary issues . existing methods suffer by ambiguous categoric boundaries, making it difficult to generate reliable pseudo-labels for each category. |
| Approach: | They propose a semi-supervised framework that assigns pseudo-labels to unlabeled data . they exploit categorical prototypes to assimilate instance representations within the same category . |
| Outcome: | Empirical studies show that the proposed framework is effective . it uses prototypical cluster separation and prototypical-center data selection . |
Text Style Transferring via Adversarial Masking and Styled Filling (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing models for text style transfer suffer from two challenges: the word masking procedure may mistakenly remove unexpected words and the selected words in the word filling procedure lack diversity and semantic consistency. |
| Approach: | They propose a style transfer model with adversarial masking and styled filling techniques to solve these challenges. |
| Outcome: | The proposed model performs well on two benchmark text style transfer data sets. |
Anaphor Assisted Document-Level Relation Extraction (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for document-level relation extraction are incomplete and lack anaphor for identifying relations between entities. |
| Approach: | They propose an Anaphor-Assisted (AA) framework for document-level relation extraction . they use a document or sentences as intermediate nodes to model cross-sentence entity interactions . |
| Outcome: | The proposed framework achieves state-of-the-art on the widely-used datasets. |
Progressively Modality Freezing for Multi-Modal Entity Alignment (2024.acl-long)
Copied to clipboard
| Challenge: | Multi-Modal Entity Alignment aims to discover identical entities across heterogeneous knowledge graphs. |
| Approach: | They propose a strategy of progressive modality freezing that focuses on alignment-relevant features and enhances multi-modal feature fusion. |
| Outcome: | The proposed approach demonstrates state-of-the-art performance and the rationale for freezing modalities. |
Parameter-free Automatically Prompting: A Latent Pseudo Label Mapping Model for Prompt-based Learning (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing manual label mapping methods that require extra parameters and human knowledge are limited in data. |
| Approach: | They propose a Latent Pseudo Label Mapping method that optimizes the label mapping without human knowledge and extra parameters. |
| Outcome: | The proposed method outperforms the standard SOTA method in few-shot learning tasks and significantly outperformed the standard ALM method which requires extra task-specific prior knowledge. |
