  • Patent number: 11700229
    Abstract: Generating an improved/more accurate geolocation database is provided. Given a dataset of reverse DNS hostnames for IP addresses, ground truth information, and a hierarchical geographical database, a machine learning classifier can be trained to extract and disambiguate location information from the reverse DNS hostnames of IP addresses and to apply machine learning algorithms to determine location candidates and to select a most probable candidate for a reverse DNS hostname based on a confidence score. The classifier can be used to generate an accurate geolocation database, or to provide accurate geolocation information as a service.

  • Patent number: 11397717
    Abstract: Data item deltas are generated for each of M updates of a plurality of updates, wherein M is greater than or equal to one, and a first first-level combined delta is generated representing N updates of the plurality of updates, wherein N is greater than M, and the N updates comprise the M updates and O=N?M other updates. A first second-level combined delta is generated representing J updates of the plurality of updates, wherein J is greater than N, and the J updates comprise the N updates and K other updates of the plurality of updates, wherein K=J?N. The deltas, the first first-level combined delta and the first second-level combined delta are stored for enabling subsequent reading of at least part of the data by accessing the data item, the first first-level combined delta and the first second-level combined delta.

  • Publication number: 20210406247
    Abstract: Systems, methods, and non-transitory computer readable media are provided for managing expiration of modules. An expiry dataset may be maintained. The expiry dataset may include a set of identifiers corresponding to a set of modules, a set of expiry values for the set of modules, and a set of termination tasks for the set of modules. A request to refresh a module may be received from a client. Responsive to the reception of the request, an expiry value and a termination task for the module within the expiry dataset may be updated. The expiry value may be independent of a timestamp associated with the request.

  • Patent number: 10091253
    Abstract: The act of setting up a user's device to participate in a meeting may be performed automatically, using location information and calendar information. With appropriate permission obtained from the user, the user's calendar and the location of the user's device are monitored. When the user's calendar indicates that the user is scheduled to be in a meeting and the user is in or approaching a conference room (or other type of room) associated with that meeting, the user's desktop, application, and meeting documents may be shared. The user's computer may be automatically connected to devices in the meeting room, and any audio/visual settings appropriate for the user's role in the meeting may be configured automatically. Alternatively, if the user is to participate in the meeting online, the online meeting may be joined automatically.

  • Patent number: 10032118
    Abstract: A system that incorporates teachings of the present disclosure may operate, for example, obtaining a number of blogs including an initial set of annotated blogs and unannotated blogs. The initial set of annotated blogs are annotated as being either relevant to a selected media program or not relevant to the selected media program. A set of features is determined associating the selected media program with the unannotated blogs and a trained classifier is generated based on the set of features. The trained classifier is applied to the blogs to identify a subset of blogs relevant to the selected media program. An analysis is performed on the selected blogs to determine a trend related to the selected media program and a graphical user interface is presented that concurrently presents the selected blogs, the trend, and the selected media program. Other embodiments are disclosed.

  • Publication number: 20170286534
    Abstract: Architecture that enables the creation and utilization of a user location profile for a personalized search experience in recommendation systems. The user location profile does not necessitate login of the user to obtain user profile information such as a user ID. Rather, the identifying information associated with the user location can be a network address and/or a device identifier that identifies the particular device from which the user is performing a search or which auto-suggest is being initiated. The user location profile can then be used to identify items about which the user may want information. Once generated, a matching operation is performed between the user location profile and item profiles in a log. The matched item profiles related to the user's location information (the user physical location and/or or user interested location(s)) are identified and recommended to the user.

  • Patent number: 9753946
    Abstract: Architecture that improves the quality of RevIP databases using search engine query logs and other location information sources and finds IP addresses that share multiple locations (indicative of large Internet gateways). A ground truth dataset is generated with mappings of IP addresses to locations and IP ranges to locations which are known to be correct. Additionally, the architecture can determine which types of queries and SERP page blocks (page sections) are location aware. Location information can be extracted from user queries and the most-frequently-used locations aggregated per IP address. Dominant locations can be aggregated, mapped to existing RevIP database IP address ranges and replaced. The updated RevIP database can be evaluated against the ground truth dataset. RevIP IP address ranges can be split and combined to improve the overall performance of the RevIP database.

  • Publication number: 20170178012
    Abstract: Architecture that processes preemptive events for an application that trigger based on user interaction movements of a specific input method (e.g., a mouse pointer) in a virtual document of the application. Machine learning is employed to predict and identify a target element the user will select in the virtual document. Thus, event triggering occurs before the user has physically performed the interaction. In response, a request that would normally be sent from the application when the user interacts with the target element(s), is prematurely cached in a system and processed to retrieve the results of the request so that when the target element is actually interacted with, the results are immediately transmitted to the user device for viewing. This saves time in the system by processing critical path operations before the user has interacted with the target element, and ultimately, produces an improved user experience with the application.

  • Patent number: 9189550
    Abstract: Embodiment described herein are generally directed to a toolbar extension of a web browser that grabs a user's search engine query and suggests a refined search query known to yield better search results. The toolbar recognizes the web page the user is on as being associated with a search engine and retrieves the user's search query. The toolbar interacts with a refinement component on a server, and the refinement component determines a refined search query based on confidence scores assigned to data mined from a data center affiliated with different search engine (one related to the toolbar). The refined search query is returned and displayed in a search field of the toolbar, allowing the user to easily run the refined search on the different search engine.
