The venue data can include records describing physical features of a venue and records describing conceptual features of the venue. A validation engine can detect conflicts between records in the venue data or conflicts between records in the venue data and external data. The conflict can include a physical conflict between two physical features, e.g., when a floor of a building is larger than a footprint of the building, a conceptual conflict between two occupants of a venue, e.g., when an airport baggage claim area is located next to a high school, or a relationship conflict between an occupant and a venue in which the occupant is allegedly located, e.g., ski resort located in an office building. The conflict can be defined in conflict rules. The validation engine can learn the conflict rules from historical venue data and truth references. | 12-03-2015 |

20150350844 | VENUE DATA FRAMEWORK - Techniques for storing information representing a venue are described. A venue data provider may upload venue data to a venue data service. The venue data can include locations, geometries, and business categories of the buildings and floors. The venue data service can validate the venue data, and request a survey service to survey the venue using the validated venue data. A survey can include recording measurements of an environment variable at various locations of the venue. The location service can generate location fingerprint data from the survey. The location fingerprint data can include expected measurements of the environment variable at various locations of the building. The venue data service can provide the location fingerprint data to a mobile device such that the mobile device can determine a location of the mobile device in the venue using sensor readings of the environment variable. | 12-03-2015 |
20150350845 | Indoor Location Survey - Methods, systems, and computer program product for generating location fingerprint data for a venue are described. A sampling device surveying a venue can move inside the venue. While the sampling device moves, the sampling device can record environmental readings including, for example, strengths of signals from multiple radio signal sources. The sampling device can take the recording at fixed or various time intervals. Meanwhile, the sampling device can determine, based on a starting point and motion sensor readings, an estimated location of the mobile device for each time the sampling device takes the recordings. The sampling device can display a motion path of the estimated locations and a user interface item for receiving a user input for correcting the estimated locations. The sample device can tag the recorded environmental readings with the corrected locations, and submit the tagged readings to a server for determining a location fingerprint for the venue. | 12-03-2015 |
