Abstract: Techniques for providing items recommendations based on a state of a merchant device are described. For example, a determination of whether or not a merchant device is in an online mode or an offline mode may be made. When it is determined that the merchant device is in the online mode, a recommendation that is received for the current transaction may be presented. When it is determined that the merchant device is in the offline mode, a recommendation that is previously received may be presented. In other examples, other types of recommendations may be presented.

Abstract: A system and method for constructing a hierarchical multi-faceted classification structure includes organizing a plurality of visual categories into a multi-relational reference ontology that accounts for a plurality of different types of relationships. Media artifacts are categorized into the plurality of visual categories. The categories of artifacts are refined based on faceted ontology relationships or constraints from the multi-relational reference ontology. The multi-relational reference ontology and the one or more media artifacts with relationships are stored as the hierarchical multi-faceted classification structure in computer readable memory storage.

Abstract: A story describing an activity performed by an interacting user is distributed to viewing users according to the influencer scores for the viewing users. Each influencer score can be calculated based at least in part on the influence of a viewing user on those users connected to the viewing user, and on the influencer scores for the users connected to the viewing user. Based on the determined influencer scores, at least one of the viewing users can be provided with the story describing the activity performed by the interacting user.

Abstract: A service provider may receive transaction information from a plurality of merchant devices for a plurality of point of sale (POS) transactions conducted between buyers and merchants. The service provider associates the transaction information with respective buyer profiles. The service provider may subsequently receive an indication of a first item selected by a particular buyer for a current POS transaction being conducted with a particular merchant. The service provider may determine a particular buyer profile to associate with the current transaction. Based at least in part on the particular buyer profile or the other buyer profiles, the service provider may determine a second item that has been purchased frequently together with the first item. The service provider sends a communication to the particular merchant to indicate that the particular merchant may wish to offer the second item to the particular buyer for inclusion in the current transaction.

Abstract: A social networking system presents content items to users, who then provide feedback regarding pairs of content items. The feedback includes a selection of a content item of the pair of content items that was preferred by the user over the other content item. The social networking system uses this information to train a predictive model that scores content items based on quality. The content items may be advertisements. The social networking system uses the pair-wise comparisons of the advertisements to determine feedback coefficients in an advertising quality score prediction model using regression analysis of the pair-wise comparisons for each predictive factor in the model. In this way, the pair-wise comparisons are used to train the prediction model to understand which advertisements are more enjoyable than others. A feedback coefficient for each predictive factor may be computed based on the preferences received from the group of users.

Each influencer score can be calculated based at least in part on the influence of a viewing user on those users connected to the viewing user, and on the influencer scores for the users connected to the viewing user. Based on the determined influencer scores, at least one of the viewing users can be provided with the story describing the activity performed by the interacting user.

Abstract: An apparatus for sharing frequencies in an orthogonal frequency-division multiplexing OFDM-based wireless communication system, wherein the OFDM-based wireless communication system comprises a base station and a mobile device that work within a radio frequency band, the method comprising: detecting an interference signal in the radio frequency band; setting by the base station, based upon the interference signal, interference indication information in a control header of a downlink frame to be sent to the mobile device, the interference indication information indicating a frequency range that is occupied by the interference signal in the radio frequency band; and sending by the base station the downlink frame to the mobile device, such that the mobile device may, based upon the interference indication information, avoid the frequency range where the interference signal is located.

Abstract: Techniques and arrangements for authorizing a payment instrument by capturing an image of the payment instrument at a point-of-sale (POS) device and uploading the image to a payment service, which performs optical character recognition (OCR) on the image to identify an identifier of the payment instrument. The payment service may then use the identifier to authorize the payment instrument for a cost of a transaction performed at the POS device.

Abstract: A seed cluster comprising a group of users who share a particular attribute and/or affiliation is determined by a social networking system. For each user of the seed cluster, other users and/or entities connected to the user in the social networking system are retrieved. For each retrieved other user or entity, the social networking system may determine whether the other user or entity exhibits the attribute or affiliation based on a random walk algorithm. A resulting targeting cluster of users and/or entities may be used for targeting advertisements targeting to members. A social networking system may also infer an affiliation for a user based on the user's interaction with a page, application, or entity where other users who interacted with the same page, application, or entity have the same affiliation.

Abstract: Systems and methods for generating and distributing photo filters are described. A photo filter publication application receives filter data and object criteria and generates a photo filter based on the filter data. The photo filter is associated with satisfaction of the object criteria. A photo filter engine then identifies that a client device has taken a photograph. The photo filter engine then provides the photo filter to the client device based on the photograph including an object that satisfies the object criteria. The photo filter may then be displayed as an option on a user interface of the client device. The object criteria may include associations between an object and a source of image data, for example, a brand of a merchant in which case the associated photo filter may include images associated with the brand of the merchant.
