Summarising Historical Text in Modern Languages (2021.eacl-main)
Copied to clipboard
| Challenge: | Historical text summarisation is a routine for historians and digital humanities researchers but has never been automated. |
| Approach: | They propose a model that can be trained even with no cross-lingual data and further benchmark it against state-of-the-art algorithms. |
| Outcome: | The proposed model outperforms standard cross-lingual benchmarks on historical text summarisation task and identifies distinctness and value of the dataset. |
Highly Efficient Knowledge Graph Embedding Learning with Orthogonal Procrustes Analysis (2021.naacl-main)
Copied to clipboard
| Challenge: | Knowledge Graph Embeddings (KGEs) have been explored in recent years due to their promise for a wide range of applications. |
| Approach: | They propose a KGE framework which can reduce the training time and carbon footprint by orders of magnitudes compared with state-of-the-art approaches. |
| Outcome: | The proposed framework reduces the training time and carbon footprint by orders of magnitudes compared with state-of-the-art approaches while producing competitive performance. |
Dual-Gated Fusion with Prefix-Tuning for Multi-Modal Relation Extraction (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for multi-modal relation extraction lack useful visual information. |
| Approach: | They propose a novel multi-modal relation extraction framework to capture deeper correlations of text, entity pair, and image/objects. |
| Outcome: | The proposed framework captures the deeper correlations of text, entity pair, and image/objects, and extracts useful information. |
Cross-Lingual Word Embedding Refinement by ℓ1 Norm Optimisation (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing methods for building high-quality CLWEs learn mappings that minimise the l2 norm loss function but this optimisation objective has been shown to be sensitive to outliers. |
| Approach: | They propose a simple post-processing step to improve cross-lingual word embeddings using the Manhattan norm goodness-of-fit criterion. |
| Outcome: | The proposed approach outperforms four state-of-the-art baselines in bilingual lexicon induction and cross-lingual transfer tasks. |
