The semantic analysis identifies negative sentiment keywords associated with one or more product characteristics in the customer review and assigns each negative sentiment keyword a value. The value of each identified negative sentiment keywords is then used to calculate a score for the product characteristic to which the negative sentiment keyword is correlated. A product recommendation report comprising the identified products, their product characteristics, a list of scored product reviews, or a combination thereof is then presented to the end user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Providing product recommendations through keyword extraction from negative reviews","description":"A product recommendation system and method identify product characteristics from customer reviews using a semantic analysis of the product review text.
