What Do Users Want? Using Semantics to Predict User Intents at Scale

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.
