Abstract: A computer-based learning system uses knowledge points organized with a predefined multilevel arrangement. Each knowledge point has an information set which may include a knowledge content, an evaluation content and a solution content. For a given knowledge point, the learning system provides the knowledge content and evaluation content, analyzes the user's answers to the evaluation content and determines the next knowledge point to be studied by the user based on the user's answers and the predefined multilevel arrangement of the knowledge points. The learning system thus provides a different learning course for different users to achieve individualized learning. User's learning history may be recorded to facilitate reviews by the user and improve the selection of the next knowledge point. Users may provide feedbacks on knowledge contents and evaluation contents, and may even suggest their own knowledge contents and evaluation contents to improve the learning system and user participation.

Abstract: Creative energy of consumers is captured and incentivized by businesses when the businesses provide personal incentives that reflect the extent to which the consumers make productive contributions to a socially networked business and consumer space. The personal incentives provide consumers lower prices through coupons, rebates, or other discounts for various items sold or distributed by the businesses. Consumers that are more productive or active in the social space can receive lower pricing on items. The personalized incentive for a particular consumer may be based on the quantity and quality of product reviews provided by the consumer as well as other factors such as consumer loyalty to a particular merchant or business. This business and consumer space spans the brick-and-mortar as well as the online retail spaces allowing consumers to use a mobile device to make online purchases by scanning a tag on a tangible object in a brick-and-mortar store.
