Cross-lingual Transfer for Text Classification with Dictionary-based Heterogeneous Graph (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to cross-lingual text classification require task-specific training data in high-resource sources . labeling cost, task characteristics, and privacy concerns can hinder the use of cross-linguistic training . |
| Approach: | They propose a dictionary-based heterogeneous graph (DHGNet) that uses bilingual dictionaries for task-independent word embeddings. |
| Outcome: | The proposed method outperforms pretrained models even though it does not access to large corpora. |
Learning Only from Relevant Keywords and Unlabeled Documents (D19-1)
Copied to clipboard
| Challenge: | Existing methods for document classification are limited due to labeling and privacy concerns. |
| Approach: | They propose a super-vised text classification framework that provides keywords as a hint for classifying a document to a target class. |
| Outcome: | The proposed framework is simple to implement and has flexible choices of models, e.g., linear models or neural networks. |
