Sentiment Analysis of Amazon Reviews

overview:

A review text usually contains emotional information, which is very useful for evaluating the quality of a product. In this Project, we will train a model to classify a sentence to 3 sentiment: positive, negative and neutral.

dataset:

We will use the Amazon Customer Reviews Dataset, which is provided from Amazon. This dataset consists of many classes, and we will use book review data from them, which is about 4.4GB in size.This is a link including all the information of those data. There are many attributes in this data set, however we will use mainly the review text as training data.

We divided the whole project into 3 part: data process, training model, and evaluating model.
