Abstract

Search is currently undergoing a major paradigm shift away from the traditional document-centric "10 blue links" towards more explicit and actionable information. Users expect the system to "understand" the user's information need and respond to it more directly instead of only serving documents matching the given set of keywords. Recent advances in this area are Google Knowledge Graph, Virtual Personal Assistants such as Siri and Google Now, as well as the now ubiquitous entity-oriented vertical search results for places, products, etc. Apart from novel query understanding methods, these developments are largely driven by structured data that is blended into the Web Search experience. Structured data can be obtained from a wide variety of documents and Web sources by tapping on information extraction and semantic markup like microformats. Additionally, the Web already offers publicly accessible knowledge bases, such as DBpedia, Yago, Freebase and the Linked Open Data cloud, as also used in Google's Knowledge Graph. Providing vast amounts of information about many different types of entities, these data sets can become very large, so sophisticated techniques for organizing and querying them are required. We discuss efficient indexing and query processing techniques to tackle these challenges. Finally, we present query interpretation and understanding methods to map user queries to these structured data sources, also highlighting the recent trend of virtual personal assistants like Siri.
