I saw there were samples but is this similar to how BloomBerry comes up with "topics" for popular questions for a keyword? They use some sort of NLP extraction of noun/verb phrases. Example: Most popular topics/themes related to Vodafone: https://app.bloomberry.com/questions;q=vodafone https://app.bloomberry.com/questions;q=vodafone
