Requirements

The purpose of this assignment is to use SAS Visual Text Analytics to analyse a dataset labelled AmazonAlexaReviews available on Moodle as a CSV file. The dataset consists of 3151 Amazon verified customer reviews of various amazon Alexa products like Alexa Echo, Echo dots, Alexa Firesticks etc . The data also includes star ratings, date of review, and variants of Alexa products. In this assignment, you will use only the customer reviews text, which is named verified_reviews. The verified_reviews variable represents free-form, unstructured customer reviews collected from Amazon's website.

You are required to conduct a data analysis of Amazon verified customer reviews using SAS Visual Text Analytics in two parts. Part 1 consists of exploring predefined concepts and automatically generated topics to derive insights from the data. Part 2 consists of defining your own custom concepts and custom categories to answer specific research questions.

Your report should have the following components:

•   A standard cover page (available on Moodle).

•   Part 1
