Sentiment Analysis for Amazon Review Dataset & Drug Dataset

Introduction

Machine learning techniques have become increasingly popular and relevant to solve text and sentiment related problems in recent years. It has boosted performance on several tasks and significantly reduced the necessity for human efforts. For this project, we will focus on text classification, especially sentiment analysis, on several datasets. Since there are researches about sentiment analysis on Amazon Review dataset, we will first use the same methods on the same dataset, and then replicate the methods on datasets other than the Amazon Reviews dataset. By completing the project, we are trying to realize the following goals:

• Build four text sentiment classifiers on Amazon Review dataset (BoW, Word2Vec, GloVe, fastText);
• Re-apply the above four classifiers on Drug Reveiw dataset;
• Compare different classifiers for datasets
