Appl. No.:

12/797778

Charles Zitnick - Seattle WA, US
Rafael Sagula - Kirkland WA, US
Ashok Chandrashekar - Hanover NH, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06K 9/62
G06K 9/68
G06K 9/70
G06K 9/36

US Classification:

382225, 382226, 382235

Abstract:

A database of images may be accessed. A feature set may be computed for each image, respectively. Each feature set includes feature integers quantized from interest points of a corresponding image. An initial set of clusters of the feature sets is found based on min hashes of the feature sets. Given the clusters of feature sets, descriptors for each of the clusters are computed, respectively, by selecting feature integers from among the feature sets in a cluster. The clusters are then refined by comparing at least some of the feature sets with at least some of the cluster descriptors, and based on such comparing adding some of the feature sets to clusters whose feature descriptors have similarity to the feature sets.

International Classification:

G06F 17/00

US Classification:

715202

Abstract:

An image service uses a uniform resource locator (URL) or other location identifier to retrieve static images embedded in dynamic content presentations from the Internet. The image service uses a set of imaging parameters to extract one or more static images embedded in the dynamic content presentation that can be consumed by the static display device. URLs to existing web pages are entered into a configuration interface on the image service. The image service parses the web pages, identifies a direct location identifier for the embedded image, and passes the direct location identifier to the static display device for direct retrieval of the embedded image. In another implementation, the image service dynamically pulls the selected embedded images from the identified web sites, and downloads the static image files for display on the static display device.

US Classification:

715749

Abstract:

An image service uses a uniform resource locator (URL) or other identifier to retrieve dynamic content presentations from the Internet. The image service uses a set of imaging parameters to render HTML files into a static image, sized appropriately, that can be presented on a static display device. A user enters URLs identifying locations of dynamic content within a configuration interface on the image service. The image service then dynamically pulls the selected content from the identified web sites, converts the web pages, or portions thereof, into static digital image files, and downloads the image files for display on a static display device.

International Classification:

G06F 15/16

US Classification:

709204

Abstract:

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users using the metapages generated for the concepts. Aggregated social information may be presented to users viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. Information on other external websites associated with the metapage may be presented as links on the pages associated with the metapage. Feedback from users may be used to include or exclude pages from being associated with a generated metapage. A best page for a concept embodied in multiple pages may be determined using a hierarchy of rules.

International Classification:

G06F 15/16
G06F 17/30

US Classification:

707723, 709204, 707E17119

Abstract:

Embodiments of the invention improve the ability of a social networking system to determine which types of data—hereinafter referred to as “fields”—are relevant to which types of user pages. Specifically, a social networking system assigns page types to different user pages, and likewise stores information on different types of fields. By analyzing the relationships of different pages and fields, the social networking system determines which types of fields are particularly well-suited for inclusion on different types of pages. Using the learned information about page types and field types, the social networking system can better aid page administrators in specifying data to add to their pages. For example, the social networking system can recommend to administrators the addition of certain types of fields or automatically add the fields. Further, the social networking system can specialize a search for social networking system data to field types.

International Classification:

G06F 17/30

US Classification:

707727, 707E17082

Abstract:

Embodiments improve the ability of users of a social networking system to search for information that is likely to be relevant to them by learning and/or applying a search context associated with selector components used to search for objects of the social networking system. The search context is specific to the use of an individual selector and thus need not be as general as the context of an entire page or set of pages in which selectors can be embedded. The social networking system may learn the context of a selector by monitoring user selections from prior search results performed using the selector.

International Classification:

G06F 9/45
G06F 9/455

Abstract:

In one embodiment, a method includes generating an executable version of a decision tree by compiling source code into executable code and verifying the executable code by comparing a result of executing the executable code with a result of evaluating the decision tree in interpreted mode. The method further includes replacing the decision tree evaluated in the interpreted mode with the executable code if the executable code is verified or discarding the executable code otherwise.
