US Classification:

707 3, 707 5, 707 6, 7071041

Abstract:

There is provided a method and system to communicate information. The system receives a first query that contains at least one constraint and retrieves a first plurality of data items from a database based on the first query. Next the system generating a first distribution based on the first plurality of data items, the first distribution utilizing a first plurality of domains used to identify data items. Next the system generates a second distribution based on a plurality of requests to view a second plurality of data items. Next the system generates a third distribution based on the first distribution and the second distribution. Finally the system generates interface information, to be communicated to a user, based on the third distribution.

US Classification:

707758, 707748, 707752, 707E17071

Abstract:

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.

US Classification:

707709, 707710

Abstract:

A computer-implemented system and method for keyword extraction and contextual advertisement generation are disclosed. The system in an example embodiment includes a keyword extraction service to receive from a consumer application a request for activation of a keyword extraction service via an application programming interface, the request including an identity of a content source, the request further including an identification of a particular extraction process to be used by the keyword extraction service on the identified content source; determine if the keyword extraction service has already processed the identified content source and retained extracted keywords in a data store; extract keywords from the identified content source using the particular extraction process identified in the request; and make the extracted keywords accessible to the consumer application.

International Classification:

G06F 17/30

US Classification:

707724

Abstract:

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 square of 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 square of linear to surface distance look-up table is used to convert the calculated square of the linear distance to a surface distance.
