Over the years search paradigm has shifted from document retrieval to deeper user intent understanding. Today’s users are no longer satisfied with seeing a list of relevant documents, instead they want to complete tasks and take actions on them. The question I will address in this talk is how to build an automated user intent understanding system, where given a query like "Mia" the user sees relevant and personalized recommendations such as "buy latest album of the singer”, or "check-in flight to Miami". I will begin by introducing the task and the main challenges with semantic understanding. Then, I will describe categorization and structured prediction algorithms for entity detection and intent prediction. Finally, I will highlight results and findings for user intent prediction from shopping, movies, restaurant and sport domains.
