JWSign: A Highly Multilingual Corpus of Bible Translations for more Diversity in Sign Language Processing (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing sign language datasets are limited and skewed towards high-income sign languages, mainly those from high-risk countries. |
| Approach: | They propose a large and highly multilingual dataset for sign language translation: JWSign. |
| Outcome: | The proposed dataset consists of 2,530 hours of Bible translations in 98 sign languages, featuring more than 1,500 individual signers. |

| Challenge: | Lower-resource corpora have systematic issues, including mislabeled or nonstandard/ambiguous language codes. |
| Approach: | They manually audit the quality of 205 language-specific corpora released with five major public datasets. |
| Outcome: | The results show that lower-resource corpora have systematic issues even for non-proficient speakers. |
Machine Translation between Spoken Languages and Signed Languages Represented in SignWriting (2023.findings-eacl)
Copied to clipboard
| Challenge: | Yin et al. ( 2021) calls for including sign language processing (SLP) in natural language processing research. |
| Approach: | They propose to use a sign language writing system to parse, factorize, decode and evaluate signed languages. |
| Outcome: | The proposed method achieves over 30 BLEU in a bilingual setup and over 20 BLUE in two multilingual setups. |
Considerations for meaningful sign language machine translation based on glosses (2023.acl-short)
Copied to clipboard
| Challenge: | In machine translation, sign language translation based on glosses is becoming more popular . limitations of glossed approaches are not discussed in a transparent manner, and there is no common standard for evaluation. |
| Approach: | They propose to use a gloss-based approach to evaluate machine translation results . they propose to include realistic datasets, stronger baselines and convincing evaluation . |
| Outcome: | The proposed approach is based on a neural gloss translation model. |
SignCLIP: Connecting Text and Sign Language by Contrastive Learning (2024.emnlp-main)
Copied to clipboard
| Challenge: | SignCLIP is an efficient method of learning useful visual representations for sign language processing from large-scale, multilingual video-text pairs without optimizing for a specific task or sign language of limited size. |
| Approach: | They propose a method for learning visual representations for sign language processing from large-scale video-text pairs without directly optimizing for a specific task or sign language. |
| Outcome: | The proposed model can learn from multilingual video-text pairs without optimizing for a specific task or sign language of limited size. |
Understanding the Properties of Minimum Bayes Risk Decoding in Neural Machine Translation (2021.acl-long)
Copied to clipboard
| Challenge: | Neural Machine Translation (NMT) currently exhibits biases such as producing translations that are too short and overgenerating frequent words. |
| Approach: | They propose to use minimum bayes risk decoding instead of beam search to investigate the effects of beam decoding on unbiased samples. |
| Outcome: | The proposed method improves on a number of previously reported biases and failure cases of beam search on unbiased samples. |
Linguistically Motivated Sign Language Segmentation (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Sign language segmentation is a crucial task in sign language processing systems. |
| Approach: | They propose to combine two kinds of segmentation: segmentation into individual signs and segmentation to segment into phrases, larger units comprising several signs. |
| Outcome: | The proposed model is based on linguistic cues observed in sign language corpora and replaces the predominant IO tagging scheme with BIO taging to account for continuous signing. |
Why Self-Attention? A Targeted Evaluation of Neural Machine Translation Architectures (D18-1)
Copied to clipboard
| Challenge: | Recent studies show that non-recurrent architectures outperform RNNs in neural machine translation. |
| Approach: | They hypothesize that CNNs and self-attentional networks could extract semantic features from source text. |
| Outcome: | The proposed architectures outperform RNNs on two tasks: subject-verb agreement and word sense disambiguation. |
