In a database, product image data is accumulated. A search portion acquires product image data having the image characteristics information that is the same as or similar to the image characteristics information that indicates the characteristics of the image of input image data from the database for the input image data. A search server outputs information on another product that is different from the product corresponding to the product image data together with the product image data acquired by the search portion.

A method of providing reservation status relating to a group of objects includes providing a database for containing (i) availability data describing availability of at least one of the group of objects, and (ii) reservation data describing allocation of at least one of the group of objects. The availability data and the reservation data are stored in sparse form. The method further includes extracting, from the database, availability data and reservation data corresponding to a predetermined period of time, and combining the extracted availability data and reservation data to form windowed data in a dense format. The method also includes receiving the windowed data and providing the windowed data in a bit-vector view, and sampling the windowed data in the bit-vector view to produce sampled data. The sampled data provides the reservation status as a static view of the windowed data in the bit-vector view.

A system and method of an intelligent shopping infrastructure is provided. A data storage of current inventory from a plurality of merchants is maintained. User preferences that indicate an item affinity of a user are retrieved. Furthermore, a location of the user is detected. Using the detected location, available inventory, and item affinity, an available item from the current inventory of a merchant located within a predetermined distance to the location of the user that match the item affinity of the user is identified. The available item is presented on a user interface of a client device of the user.

A computer-implemented method for searching information and an electronic device are disclosed. The method includes: receiving, at one or more computing devices, a search term; acquiring, at the one or more computing devices, a 3D search result corresponding to the search term if the search term includes a 3D search requirement, in which the 3D search result includes a 3D picture and one or more service items corresponding to the 3D picture; displaying, at the one or more computing devices, the 3D search result; determining, at the one or more computing devices, a service item selected by a user; and processing, at the one or more computing devices, the 3D picture according to the service item. The method can provide a service on the basis of the 3D search result when the user has the 3D search requirement, thereby better satisfying the user' requirement and improving the user experience.

Methods, systems, and computer program products for re-computing pre-computed search results, such as pre-computed priced recommendations. Pre-computed search results stored in a search platform are subdivided into shares of related pre-computed search results including a first share. A re-computation controller determines a validity trend indicating a change rate of a validity probability of a pre-computed search result over time and an instantaneous validity rate for the pre-computed search results. If a difference between the instantaneous validity rate and the validity trend exceeds a given extent, the re-computation controller adjusts the validity probabilities being associated with other pre-computed search results included in a second share correlated with the first share. The re-computation controller issues re-computation orders to a computation platform to re-compute a part of the pre-computed search results, the part being selected by the re-computation controller on the basis of the validity probabilities associated with the pre-computed search results.

A method and system for intuitive content browsing. The method includes determining, based on a request to browse content, an initial focal point for a visual representation of the content, wherein the initial focal point represents a content item; identifying, based on the request and the determined initial focal point, the content to be browsed; generating, based on the identified content and the focal point, a visual representation of the identified content, wherein the generated visual representation includes the identified content organized with respect to the initial focal point; and sending, to a user device, the generated visual representation for display, wherein the identified content is browsed via the displayed visual representation with respect to the focal point.

In one embodiment one or more service provider work product of a knowledgebase can be processed according to one or more methods. A knowledgebase can be provided that includes a work product of one or more service provider. According to one method one or more work product of a knowledgebase can be processed.

Example embodiments described herein disclose a specially configured device to receive and recognize enhanced user interactions through a graphical user interface. A user device may accordingly receive and display a set of search results, detect a user input entered via a touch-input device related to a single item from among the set of search results, determine a pressure exerted upon the touch-input device corresponding to the user input, and based on at least the pressure of the user input, select and execute an appropriate commerce action.

Embodiments of the present specification provide product information query methods and systems. In an embodiment, a method comprising detecting, by a distance sensor, a moving object that enters a predetermined detection range, wherein the moving object comprises a product; sending, by the distance sensor, a notification that that notifies a computer of the one or more computers to enable a query of the product; photographing, by a photographing device, an image of the product; obtaining, by a computer, the image from the photographing device; extracting, by the computer and from the image, image features of the product; performing, by the computer, the query to obtain product information based on the image features; and displaying, by a display, the product information.

An order delivery processing method includes: extracting target location information and merchant location information from a received order; determining whether the order is in a preset delivery range according to the target location information and the merchant location information; delivering the order based on a first preset rule when the order is not in the preset delivery range; sending first order-taking notification information to a merchant in response to receiving an order-taking operation of a deliverer in the target deliverer set; determining the order is effective in response to receiving an order-taking operation fed back by the merchant in response to the first order-taking notification information; and delivering the order based on a second preset rule when the order is in the preset delivery range.
