An information processing method is disclosed which includes the steps of: (a) calculating levels of similarity between a standard form vector as a comparison basis vector and each of a plurality of item characteristic vectors of the standard form which are characteristic of a plurality of items, the standard form vector being made up of N components individually representative of N attributes of each of the plurality of items, N being an integer of at least 1, step (a) further determining as the items to be recommended to a user a plurality of items corresponding to the item characteristic vectors of which the level of similarity satisfies a first condition; (b) determining one of the N attributes of the plurality of recommended items determined in step (a) as a common recommendation reason common to the plurality of recommended items when the determined attribute satisfies a second condition; and (c) controlling presentation to the user of either the plurality of recommended items determined in step (a) or information about the recommended items, together with the common recommendation reason determined in step (b).

Systems and methods for correcting a location of a terminal are provided. In various aspects, a processor in a position correction apparatus may associate a reference position with the terminal, and determine a range for the terminal based on the reference position. The processor may also associate a second position with the terminal, and determine if the second position associated with the terminal is outside the determined range for the terminal based on the reference position. Upon a determination that indicates that the second position is outside the determined range, the processor may correct the second position to a corrected position associated with the terminal.

An advertisement selecting system is disclosed providing, when selecting advertisements to be exposed to subscribers over the Internet, exposure control reflecting the inventory of advertisements by taking into account results of past exposure of each of the advertisements. When subscribers with a particular profile biased to specific tastes or preferences gain access to contents carrying advertisements, the first-ranked advertisement, i.e., the one best targeted for the subscribers in question, is exposed repeatedly but in a manner also making way for the advertisements in second and subsequent places which would be less likely to be exposed if handled conventionally, so that the stocked advertisements are exposed in fairly averaged fashion. Advertisement exposure is thus controlled in a manner averting lopsided exposure of certain (or partial) advertisement information by giving consideration to the advertisement inventory.

Systems and methods are disclosed for determining the preferences of a user of an information processing apparatus. This may be achieved, for example, by an information providing apparatus sending sample content data representing the contents database to the information processing apparatus. Then, the sample content data may be evaluated, and the evaluation results may be sent to the information providing apparatus. The information providing apparatus may then derive user preference information based on the evaluations results.
