Content Discovery with Semantic Flows

Recommendation system is a powerful tool to increase customer engagement and satisfaction for media industry. Existing approaches rely on measuring similarity between contents and similarity between customers. In this talk, I am introducing Sky’s patent-pending machine learning research by looking at the recommendation problem from a different angle: what is the benefit of learning dissimilarity? In particular, I will introduce semantic flow, a brand-new approach, to measure semantic distance between concepts and its capability on recommending exciting and surprising contents to customers.
