Look inside

In this liveProject, you’ll fill the shoes of a developer for an e-commerce company looking to build a machine learning solution to help identify bad product reviews. If one of your company’s products receives too many bad reviews, it’s policy to take it down from the e-commerce store. Until now this process has been manual—but your boss has decided that this is too expensive and time-consuming.

Your mission is to automate this process, dramatically increasing the speed of identifying bad reviews, and decreasing the cost to your company. To complete this project you will have to train a machine learning model to recognize and rank positive and negative reviews, expose this model to an API so your website and partner sites can benefit from automatic rankings, and build a small webpage that can run your model for demonstration.
