BERT Post-Training for Review Reading Comprehension and Aspect-based Sentiment Analysis

NAACL 2019 howardhsu/BERT-for-RRC-ABSA

Since ReviewRC has limited training examples for RRC (and also for aspect-based sentiment analysis), we then explore a novel post-training approach on the popular language model BERT to enhance the performance of fine-tuning of BERT for RRC.

An Unsupervised Neural Attention Model for Aspect Extraction

ACL 2017 ruidan/Unsupervised-Aspect-Extraction

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.

Jointly Modeling Aspect and Sentiment with Dynamic Heterogeneous Graph Neural Networks

14 Apr 2020lixin4ever/BERT-E2E-ABSA

Target-Based Sentiment Analysis aims to detect the opinion aspects (aspect extraction) and the sentiment polarities (sentiment detection) towards them.

Double Embeddings and CNN-based Sequence Labeling for Aspect Extraction

ACL 2018 howardhsu/DE-CNN

Unlike other highly sophisticated supervised deep learning models, this paper proposes a novel and yet simple CNN model employing two types of pre-trained embeddings for aspect extraction: general-purpose embeddings and domain-specific embeddings.

Summarizing Opinions: Aspect Extraction Meets Sentiment Prediction and They Are Both Weakly Supervised

EMNLP 2018 stangelid/oposum

We present a neural framework for opinion summarization from online product reviews which is knowledge-lean and only requires light supervision (e. g., in the form of product domain labels and user-provided ratings).
