Adversarial Training for Aspect-Based Sentiment Analysis with BERT

IMPLabUniPr/Adversarial-Training-for-ABSA 30 Jan 2020

In this work, we apply adversarial training, which was put forward by Goodfellow et al. (2014), to the post-trained BERT (BERT-PT) language model proposed by Xu et al. (2019) on the two major tasks of Aspect Extraction and Aspect Sentiment Classification in sentiment analysis.

An Unsupervised Neural Attention Model for Aspect Extraction

ruidan/Unsupervised-Aspect-Extraction ACL 2017

Unlike topic models which typically assume independently generated words, word embedding models encourage words that appear in similar contexts to be located close to each other in the embedding space.

Interactive Attention Networks for Aspect-Level Sentiment Classification

songyouwei/ABSA-PyTorch 4 Sep 2017

In this paper, we argue that both targets and contexts deserve special treatment and need to be learned their own representations via interactive learning.
