摘要： A system and method to sort search results based upon a desirability value is illustrated. This desirability value may be based upon the difference between a demand value and a supply value. Demand may be based upon user activity such as click-throughs, purchases, price, or location. Supply may be based upon a supply of keywords that may be the number of times a word is used in search or item title. The system and method may include receiving a search query, associating a first numerical value with a keyword that is a part of the search query, tracking user activity associated with the keyword, associating a second numerical value with the keyword based upon the user activity, finding a difference value between the first and second numerical values, associating this difference value with the keyword, sorting keywords based upon the difference values, and returning the search results of the sorting.

摘要： In an example embodiment, a method of identifying an item depicted in an image is provided. In this method, the image depicting the item is accessed; in addition, other images and their item identifiers are also accessed. A match of the image with one of the other images is identified. With a match, the image is then associated with an item identifier of the matched image.

摘要： A method and apparatus for calculating the surface distance between two geographical locations are described. According to one aspect of the present invention, values are stored in a square look-up table for determining the square of a value. Also, values are stored in a linear to surface distance look-up table for determining the surface distance of a linear value. Cartesian co-ordinates of the two geographic locations and the square look-up table are then used to calculate the square of the linear distance between the two geographical locations and the linear to surface distance look-up table is used to convert the calculated square of the linear distance to a surface distance.

摘要： In various exemplary embodiments, a system and method is disclosed to analyze event streams of a user session. One embodiment of the method includes logging a plurality of events from an event stream, specifying conditions to sort the plurality of events, applying the conditions to the plurality of events, producing a probability distribution of event nodes after a given node in the event stream, and producing an interactive graphical reduction of a produced graph by determining patterns in a graphical tree and unifying occurrences of the patterns.

摘要： A weather forecasting system and method. The system includes a mobile computing device that may request, from a server, real-time weather data at an exact time for a location. The real-time weather data include weather data from up to sixty minutes prior to the exact time. The system predicts future weather data for up to sixty minutes after the exact time. The system converts this real-time future weather data into speech data for output to a user.
