Before text processing, analyze the numeric ratings customers have assigned to various products.
Although numeric ratings on product reviews can help identify a specific products that has issues, we may not understand why customers don’t like the product. We could simply read through all the comments associated with that product to learn this information, but that approach doesn’t scale. So, we will use Hive’s text processing support to analyze the comments.
