Variational Semi-supervised Aspect-term Sentiment Analysis via Transformer [article]

Xingyi Cheng, Weidi Xu, Taifeng Wang, Wei Chu
2019 arXiv   pre-print
This paper proposes a semi-supervised method for the ATSA problem by using the Variational Autoencoder based on Transformer (VAET), which models the latent distribution via variational inference.  ...  Our method is classifier agnostic, i.e., the classifier is an independent module and various advanced supervised models can be integrated.  ...  Classifier Various currently available models can be used as the classifier.  ...

Emotion Detection for Spanish by Combining LASER Embeddings, Topic Information, and Offense Features

Fedor Vitiugin, Giorgio Barnabò
2021 Annual Conference of the Spanish Society for Natural Language Processing  
We propose a novel model for Emotion Detection that combines transformers embeddings with topic information and offense features.  ...  As for the leader-board, our classification model achieved a macro weighted averaged F1 score of 0.661427, and a overall accuracy of 0.675725, reaching the 9th and 10th place respectively.  ...  To prove the need of using additional topic and offense feature vectors we also used only transformer embeddings as input to a LSTM model.  ...

2020 arXiv   pre-print
Leveraging the flexibility and speed of a recently proposed Levenshtein Transformer model (Gu et al., 2019), our method injects terminology constraints at inference time without any impact on decoding  ...  Previous work either required re-training existing models with the lexical constraints or incorporating them during beam search decoding with significantly higher computational overheads.  ...  We use the WMT'17 En-De test sets released by Dinu et al. (2019) 8 that were created based on Wiktionary and IATE term entries exactly matching the source and target.  ...
