This presentation focuses on the design and evolution of the LinkedIn recommendations platform. It currently computes more than 100 billion personalized recommendations every week, powering an ever growing assortment of products, including Jobs You May be Interested In, Groups You May Like, News Relevance, and Ad Targeting. We will describe how we leverage Hadoop to transform raw data to rich features using knowledge aggregated from LinkedIn's 100 million member base, how we use Lucene to do real-time recommendations, and how we marshal Lucene on Hadoop to bridge offline analysis with user-facing services.
