Sentiment Analysis

Overview

Sentiment Analysis is the process of computationally identifying and categorizing opinions expressed in an article or text. This helps to determine whether the writer’s attitude towards a particular topic, product, etc. is positive, negative, or neutral.

Businesses today are connected with their customers through different channels like social, blogs, e-commerce sites, etc. Customers typically express their experience in reviews about the product over such different channels. It’s critical for the business to analyze these reviews and drive analytics to drive product future.

Sample Review:
Great value smartphone! Good camera & picture quality. Easy to use Android system. Good battery life. There is no external SD slot is a big issue for me. Amazon did a great job getting it to me quickly. I am not able to install new apps because of insufficient Storage.
