Abstract: Embodiments of the present invention provide a method for identifying discrepancies in digital map data, comprising selecting one or more candidate locations as a subset of locations within positional data relating to the movement of a plurality of devices with respect to time in an area, allocating each of the candidate locations to one or more predetermined categories based upon a distribution of travel directions of the devices at each candidate location and comparing the candidate locations against a database of map data and identifying locations of possible discrepancies in the digital map data based upon the category of each candidate location.

Abstract: According to some aspects, a system for detecting a designated wake-up word is provided, the system comprising a plurality of microphones to detect acoustic information from a physical space having a plurality of acoustic zones, at least one processor configured to receive a first acoustic signal representing the acoustic information received by the plurality of microphones, process the first acoustic signal to identify content of the first acoustic signal originating from each of the plurality of acoustic zones, provide a plurality of second acoustic signals, each of the plurality of second acoustic signals substantially corresponding to the content identified as originating from a respective one of the plurality of acoustic zones, and performing automatic speech recognition on each of the plurality of second acoustic signals to determine whether the designated wake-up word was spoken.

Abstract: The invention relates to a method of obtaining and storing data relating to a count of journeys made between origin and destination pairs in respect of different predetermined time periods. Positional data is received from vehicles, and filtered to obtain positional data relating to travel between each of a plurality of origin-destination pairs. The filtered positional data is analysed to obtain multiple sets of profiles. Each set of profiles represents a count of journeys made between the origin and destination in a plurality of predetermined time periods for each origin-destination pair. The different sets of profiles relate to different days of the week, and journeys having arrival or departure times in the predetermined time periods. The sets of profiles are used in a clustering operation to provide a reduced set of standard profiles.

Abstract: Methods and apparatus to process a user input on independent applications that provide classifier outputs to an arbitration module, which selects one of the application to respond to the user input. The classifier outputs include a probability that the user input is in domain for the application functionality.
