Abstract: A system to effectuate passive check-in with respect to a user's mobile device is described. A server system may be configured to receive communications from a GPS-enabled mobile device (e.g., a mobile phone), extract a stream of locations from the received communications, and use the location information to determine whether a boundary-crossing event has occurred with respect to the mobile device. In response to detecting a boundary-crossing event, the server stores special locations information in a profile that represents the user with respect to a web-based service.

Abstract: A method, system, and article of manufacture for disambiguating ambiguous queries based on location information. The system receives a query and location information for where the query was transmitted. Business information is requested from a GPS service. Based on the business information, a plurality of item categories are constrained to an item category related to the business information that satisfies the query. The constrained item category is sent to the user. The system may detect the absence of an item category related to the business information that satisfies the query, and may then determine one or more item category that does not meet the query but is related to the business information, to provide to the user. Other information related to the transmission of the query, such as the type of device, background audio, and the activity of the user, may used to constrain the plurality of item categories.

Abstract: A method and apparatus are disclosed for a method and apparatus for implementing an auto wait list process in scheduling or calendaring appointments. In one embodiment, the method includes selecting an appointment slot, wherein the appointment slot includes a date and a time and the appointment slot is unavailable for scheduling purposes. The method further includes enabling a user to submit the appointment slot to a wait list. In addition, the method includes saving the appointment slot as a wait list entry in the wait list at the user's submission. The method also includes notifying the user when the appointment slot becomes open due to rescheduling or cancellation, and asking the user whether the user wishes to accept the appointment slot. Furthermore, the method includes assigning the appointment slot to the user, and notifying the user of the assignment.

Abstract: Methods, systems, and apparatus for defining, generating, utilizing, and/or detecting a geo-fence are described. A definition of a geo-fence is obtained, the geo-fence being defined based on a first geo-fence criterion of a plurality of geo-fence criteria. A trigger is obtained, the trigger generated in response to a change in the geo-fence criterion. One or more boundaries of the geo-fence based on the changed first geo-fence criteria are redefined in response to obtaining the trigger.

Abstract: A system comprising a computer-readable storage medium storing at least one program and a computer-implemented method for a geo-fenced zone of commerce are described. Consistent with some embodiments, the method may include subdividing a geographic area, generating corresponding geo-fences, and presenting the corresponding geo-fences as listings in a navigable online marketplace.

Abstract: Techniques for determining location of a networked computing device are presented herein. An association module may be configured to associate two or more co-located computing devices based on an association selected from the group consisting of a common user, network address similarities, local communications between the two or more co-located computing devices, and co-location patterns. A location module may be configured to determine the location for the one of the two or more co-located computing devices, at least in part, based on a location of an associated computing device.

Abstract: Systems and methods to arrange transactions are described. A transaction request may be received from transaction parties. The transaction request may include transaction data. Geographic region data associated with the transaction parties using the transaction data may be retrieved. A mutual geographic region based on the geographic region data may be determined. Suggested transaction locations based on the mutual geographic region may be determined. The suggested transaction locations may be recommended to the transaction parties.

Abstract: Systems and methods for facilitating location-aware listing publication are discussed. A listing can include an item location corresponding to an item described in the listing. The listing may be received on a central server from a device operated by a first user. A geofence can be generated around the item location corresponding to the item described in the listing. The geofence surrounding the item location can be monitored for a second user. A second user can be detected within the geographical area enclosed by the geofence. In response to detecting the second user, a determination can be made as to whether the second user has indicated an interest in the item described in the listing. In response to the determination, the listing can be transmitted to a second device operated by the second user to notify the second user of the published listing.
