Abstract: Online selling mechanism creation is described, for example, whereby a retailer with business goals and constraints benefits from automatic generation and execution of software which controls generation of online offers so as to meet the business goals within the constraints. For example, as business goals and constraints change over time, bespoke selling mechanisms may be automatically updated. In various examples business goals are used to select selling mechanisms from a plurality of available online selling mechanisms; properties of the selling mechanisms may be taken into account. In examples, generic software implementing the selling mechanisms is used to instantiate a bespoke selling mechanism according to particular business goals and constraints. For example, a bespoke selling mechanism may be executed at a commerce server so as to control dynamic generation of offers.

Abstract: Automatically alternating between input modes on a computing device based on a usage pattern is provided. A first input mode is initiated for interacting with content displayed on the computing device. An input corresponding to a second input mode on the computing is then detected. A transition is then made from the first input mode to the second input mode on the computing device. Upon the detecting a termination of the input on the displayed content the second input mode, a gradual transition is made from the second input mode to the first input mode based on a current sensor state of the computing device and a threshold.

Abstract: An advertisement system which uses a retailer inventory is described, for example, to dynamically generate advertisements with data from the retailer inventory. In various examples product data from a retailer inventory such as numbers of remaining units of a product, is available to an advertising server by querying a retailer inventory. In various examples a retailer is able to create an advertisement design for a selling period; the design is used to dynamically generate advertisements in response to advertisement impression requests from information retrieval systems, dedicated sales sites, and other entities. In various examples, prices, minimal bids and other data is calculated using data retrieved from a retailer inventory and input to advertisements generated for display at end user devices. In an example group buying is facilitated by generating advertisements stating a current number of participants out of a target number of participants.
