1. A method comprising:

  • receiving, at a computer system from a user electronic device, a query related to an electronic media work comprising an image displayed at the user electronic device;

    extracting, using the computer system, one or more features of the electronic media work, wherein the extracted features are a compact representation of the electronic media work;

    identifying, at the computer system, action information associated with the query based at least in part on an approximate nearest neighbor search, which is a sub-linear search of an electronic database of reference features corresponding to one or more reference works that identifies any match within a threshold of at least one of the reference features to the extracted one or more features but does not guarantee to identify the closest match to the extracted one or more features; and

    providing, by the computer system to the user electronic device, machine readable instructions to perform an action associated with the identified action information, which action includes displaying additional information associated with the query.
