Code for A Dependency Syntactic Knowledge Augmented Interactive Architecture for End-to-End Aspect-based Sentiment Analysis

Introduction

The implementation is based on IMN and the dataset we used is also from IMN. The dependency tree is generated by spaCy. Download Glove file and the bert-based feature used in this Repo is produced by BERT. The dependency tree (i.e., *.pkl) is generated by prepare_data_A.py and utils_opinion.py, most of the two files are adapted on this.

Usage

Training and evaluating with the following scripts (the Hyper-parameters are shown in 'train.py' file and you may change them for better results):

bash train.sh

Requirements

• Python 2.7
• Keras 2.2.4
• tensorflow 1.4.1
