Walmart has acquired Aspectiva, a start-up that uses AI and natural language processing to analyze user-generated content (such as product reviews) and combine it with shopper browsing behavior.

The result is that it can make product suggestions to shoppers both online and in-store. Shoppers can also search and filter products based on the criteria they choose. Aspectiva likens the technology to being accompanied by a personalized, knowledgeable in-store assistant while consumer shop.
