Among other things, videos and commercials are downloaded to a mobile device for storage on the mobile device and later playout on the mobile device. The downloading includes downloading of metadata associated with the commercials and based on which the mobile device can select commercials for insertion into videos being played back to the user of the mobile device. The commercials to be downloaded are selected based on one or a combination of any two or more of the location of the user, the type of mobile device, and personally-identifiable information about a user of the mobile device.

The present disclosure is directed to associating computing devices with each other based on computer network activity for selection of content items as part of an online content item placement campaign. A first linking factor is identified based on a connection between a first device and the computer network via a first IP address during a first time period, and based on a connection between a second device and the computer network via the first IP address during the first time period. A number of devices that connect with the computer network via the first IP address is determined. A positive match probability is generated. A second and third linking factors are monitored. A negative match probability is determined based on the second and third linking factors. The first device is linked with the second device based on the positive and negative match probabilities.

A method, system, and computer program product for managing user identification codes in an interne advertising environment. One aspect implements a system including a database engine to store a plurality of signals comprising characteristics and/or values received from a user device. A user ID generator calculates collision statistics and/or fragmentation statistics to form a first mapping function that is in turn used to generate a plurality of identification codes based at least in part a first set of selected signals. A calibration module produces measurements determined from collision quantities and/or fragmentation quantities using the first mapping function, wherein the measurements are determined by comparing the plurality of identification codes to entries in a known ID database. A sequencing module generates updated sequences of mapping functions.

A system and method for providing personalized recommendations or promotional information to consumers based upon a recommendation algorithm selected from a number of recommendation algorithms, by matching personal contextual information of each consumer to detailed contexts in which each recommendation algorithm exhibits optimal performance with regard to particular business performance measures.

Methods and arrangements are provided to valuate advertising slots for a client device based on events that are detected on the device. The cost of the advertising slots can vary according to the timing of the user interactions or according to different classifications for the client device that are determined based on the events. The cost of the advertising slot can be determined before or after the invitational content is provided to the client device.

According to an embodiment, a computer-implemented method stores a set of historical transaction records pertaining to past consumer transactions, contextual transaction data, and offer activation and redemption tracking logs; receives a request to generate a new item offer; and uses a parameter optimizer to create suggested additional parameters. The parameter optimizer receives the stored records and data and determines a potential impact of the suggested additional parameters on sales of the item. In an embodiment, a visualization of the impact of the set of the parameters is presented on an offer definition interface. In an embodiment, the suggested additional parameters are automatically sent to the offer provider based in part on previous offer data associated with the offer provider.

A QR code is caused to be displayed on a display device. The QR code encodes therein a URL including an address of an application store website at which a software application for a hospitality establishment can be downloaded by a mobile device, an application identifier for uniquely identifying the software application from other software applications provided by the application store, and a connect code parameter for uniquely identifying a media device with which the mobile device is to be associated. When the mobile device scans the QR code prior to installation of the software application, the mobile device is directed to the URL and the application store website ignores the connect code parameter. When the mobile device scans the QR code after installation of the software application, the software application prevents redirecting the mobile device to the application store website and instead authenticates using the connect code.

A system and method for facilitating electronic commerce over a network, according to one or more embodiments, includes communicating with a user via a user device and a business entity via a business entity device over the network, monitoring user navigation events over the network, determining a mood of the user based on user navigation behavior, marketing to the user based on the mood of the user, and storing user information related to the user navigation events and the mood of the user.

Systems and methods for personalization using image clouds to represent content. Image clouds can be used to identify initial user interest, present recommended content, present popular content, present search results, and present user profile information. Image clouds are interactive, allowing users to select images displayed in the image cloud, which can contribute to presenting more personalized content as well as updating a user's profile.

A system and process for coordinating streaming content or messages is provided. A network-connected server maintains a database containing media content-related data, such as the text of a message, accompanying media, time of airing, payment and related comments. A user can view these feeds or streams of these consciousness messages by downloading a mobile application or browsing to a website. The application can also be used to create, schedule and pay for a media content message.
