Hierarchy-aware Label Semantics Matching Network for Hierarchical Text Classification (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods ignore the semantic relationship between text and labels, so they cannot make full use of hierarchical information. |
| Approach: | They propose a hierarchy-aware label semantics matching network to model the semantic relationship between text and labels in a semantic matching problem. |
| Outcome: | The proposed model captures the text-label semantics matching relationship among coarse-grained labels and fine-grain labels in a hierarchy-aware manner. |
CATE: A Contrastive Pre-trained Model for Metaphor Detection with Semi-supervised Learning (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing models for metaphor detection require a large amount of labeled data and are not linguistically-based. |
| Approach: | They propose a ContrAstive pre-Trained modEl (CATE) for metaphor detection with semi-supervised learning using a pre-trained model to obtain a contextual representation of target words. |
| Outcome: | The proposed model outperforms existing models on several benchmark datasets and achieves better performance against state-of-the-art models. |
A Span-based Dynamic Local Attention Model for Sequential Sentence Classification (2021.acl-short)
Copied to clipboard
| Challenge: | Existing methods for sentence classification ignore latent segment structure of document, in which contiguous sentences have coherent semantics. |
| Approach: | They propose a span-based dynamic local attention model that captures structural information by supervised dynamic local focus. |
| Outcome: | The proposed model outperforms state-of-the-art models on two benchmark datasets. |
MODE-LSTM: A Parameter-efficient Recurrent Network with Multi-Scale for Sentence Classification (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing models for sentence classification use linear convolution, which may not be sufficient to model the non-consecutive dependency of the phrase and may overfit the sequential information. |
| Approach: | They propose a model that extracts multi-scale n-gram features for understanding the semantic meaning of sentences by some key-phrases located at different positions. |
| Outcome: | The proposed model outperforms existing models on eight benchmark datasets and is competitive against state-of-the-art models. |
