Abstract: A method and apparatus that generates a plurality of ranked query results from a query over a plurality of separate search domains. In this embodiment, the device receives the query and determines a plurality of results across the plurality of separate search domains using the query. The device further characterizes the query. In addition, the device ranks the plurality of results based on a score calculated for each of the plurality of results determined by a corresponding search domain and the query characterization, where the query characterization indicates a query type.

Abstract: The subject technology provides for converting natural language input to structured queries. The subject technology receives a user input query in a natural language format. The subject technology determines scores for candidate entities derived from the user input query. The subject technology selects an entity with a highest score among the candidate entities, and converts, using a context-free grammar, the user input query to a structured query based at least in part on the selected entity. The subject technology classifies the structured query to an expected answer type, the expected answer type corresponding to a type of an expected answer of the structured query. The subject technology queries a database based on the expected answer type and the structured query, the database including information corresponding to a knowledge graph. The subject technology provides, for display, an answer to the user input query based on a result of querying the database.
