Papers with cross-lingual learning
Bridging the Gap between Native Text and Translated Text through Adversarial Learning: A Case Study on Cross-Lingual Event Extraction (2023.findings-eacl)
Copied to clipboard
| Challenge: | Recent research in cross-lingual learning has found that combining large-scale pretrained multilingual language models with machine translation can yield good performance. |
| Approach: | They propose a model architecture that jointly encodes a source language input sentence with its translation to the target language during training and takes a target language sentence with it as input during evaluation. |
| Outcome: | The proposed model architecture can integrate machine translation to improve event extraction while adding machine-translated data yields unstable performance due to representational gap. |
Leveraging Multi-lingual Positive Instances in Contrastive Learning to Improve Sentence Embedding (2024.eacl-long)
Copied to clipboard
| Challenge: | Recent trends in learning monolingual and multilingual sentence embeddings are based on contrastive learning (CL) among an anchor, one positive and multiple negative instances. |
| Approach: | They propose to leverage multiple positives to improve learning of multilingual sentence embeddings by using an anchor, one positive, and multiple negative instances. |
| Outcome: | The proposed approach improves retrieval, semantic similarity, and classification performance on unseen languages. |
Cross-lingual Transfer of Monolingual Models (2022.lrec-1)
Copied to clipboard
| Challenge: | Existing studies on cross-lingual learning using multilingual models cast doubt on shared vocabulary and joint pre-training . et al. (2005) show that model knowledge learned in the source language enhances the learning of the target language independently of language proximity. |
| Approach: | They propose a method for transferring monolingual models to other languages through continuous pre-training and investigate their results in English. |
| Outcome: | The proposed method outperforms a model trained from scratch in the GLUE benchmark for English . it shows that model knowledge from the source language enhances the learning of syntactic and semantic knowledge in english. |
Cross-lingual CCG Induction (N19-1)
Copied to clipboard
| Challenge: | Combinatory categorial grammars are linguistically motivated and useful for semantic parsing, but costly to acquire in a supervised way and difficult to acquire unsupervised. |
| Approach: | They propose an alternative using a source-language parser and a parallel corpus to induce a grammar and parsing model for a target language. |
| Outcome: | The proposed model outperforms POS tags on 3 out of 8 languages and unsupervised CCG induction on 6 out of 8. |
Can Machine Translation Bridge Multilingual Pretraining and Cross-lingual Transfer Learning? (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing models that pretrain for cross-lingual tasks do not improve cross-linguistic learning. |
| Approach: | They propose to employ machine translation as a continued training objective to enhance language representation learning by bridging multilingual pretraining and cross-lingual applications. |
| Outcome: | The proposed model performance is compared with existing models and their latent representations. |
Zero-Shot Cross-Lingual Opinion Target Extraction (N19-1)
Copied to clipboard
| Challenge: | Aspect-based sentiment analysis involves the recognition of opinion target expressions . supervised learning algorithms are usually employed to extract OTEs from text . |
| Approach: | They propose a zero-shot cross-lingual approach for the extraction of opinion target expressions . they leverage multilingual word embeddings that share a common vector space across languages . |
| Outcome: | The proposed approach can perform accurate prediction on a target language without using annotated samples. |
On the Role of Parallel Data in Cross-lingual Transfer Learning (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing multilingual models do not exploit the full potential of monolingual data, a new study finds . prior work has shown that parallel data is beneficial for cross-lingual learning, but it is unclear if it is the data itself or the modeling of parallel interactions that matters. |
| Approach: | They compare unsupervised machine translation to supervised machine translator and gold parallel data to generate synthetic parallel data. |
| Outcome: | The proposed model generated parallel data is better than supervised machine translation and gold parallel data in both general and task-specific settings. |
KINNEWS and KIRNEWS: Benchmarking Cross-Lingual Text Classification for Kinyarwanda and Kirundi (2020.coling-main)
Copied to clipboard
| Challenge: | low-resource African languages are traditionally left behind because of the lack of well-annotated data and effective preprocessing. |
| Approach: | They propose two news datasets for multi-class classification of news articles in two low-resource African languages. |
| Outcome: | The proposed datasets show that training embeddings on the higher-resourced Kinyarwanda yields successful cross-lingual transfer to Kirundi. |
