>"Google NLP algorithms use quora and trip advisor like training data sets." I understand that Google competes with Trip Advisor with their own travel offering but might you or someone else explain how they use NLP algorithms steal business from them? Also could you elaborate on how they might be using NLP on Quora to their advantage. Where or how do they compete with Quora exactly? Thanks.
