We can notice every business is try getting in the habit of asking for customer reviews. These reviews help companies to understand their customer needs better and improve the customer satisfaction by promoting quality products. Reviews and Feedback is worthless if we don't analyze and figure out what the true needs and problems of the customers are and/or don't actually act on it and use it actively and continuously to develop and drive the business forward. It is difficult to go through tons of reviews manually to act upon customer reviews/problems.

The Solution

Manually gathering information about user-generated data is time-consuming. By using this insightful information, we have developed an end-to-end “Recommendation System” based on “Sentiment Analysis of Product Reviews” using Machine Learning and Natural Language Processing.

  • Sarcasm: Sarcasm is a type of sentiment where people express their negative feelings using positive or intensified positive words in the text
  • Negation Detection: To detect negation effect on consumer reviews which looks like positive but exactly negative in sense

The Benefits

This system can be used across different industries like E-commerce, Retail, Health care and social media platforms. This helps companies to gain a positive niche in customers’ expectations with more established competition in the market. 

Listed below are some of the benefits of how Sentiment based automated solutions help companies.

  • Improve customer experience
