Abstract: 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.

Abstract: Techniques are disclosed for selecting an item to recommend to a user from a plurality of items. A first set of scores indicating degrees of association between items of the plurality of items may be calculated using a first scoring algorithm having a first scale, and a second set of scores indicating degrees of association between items of the plurality of items may be calculated using a second scoring algorithm having a second scale. The second set of scores may be adjusted to match the second scale to the first scale, and a third set of scores may be calculated for the plurality of items by combining the first set of scores and the adjusted second set of scores. An item may be selected from the plurality of items to recommend to the user based on the third set of scores.

Abstract: To improve the convenience of a user and further provide service comfortable and safe for the user. A PK 22 storing PMD as personal related information of a user 20 communicates with a service system 24. When first using the service system 24, the PK 22 stores the service ID of the service system 24 and a spoofing preventing method. When the PK 22 communicates with the service system 24 for a second time and thereafter, a spoofing preventing process is mutually performed, and then the PMD is provided to the service system 24. The service system 24 reads or changes the PMD on the basis of access permission information set in advance by the user 20. The present invention is applicable to PDAs.

Abstract: There is provided an information processing device including a content analysis unit configured to analyze a group of content by setting individual pieces of content included in the group of content as nodes of a graph structure and a link between the pieces of the content as a link of the graph structure, and a learning support information generation unit configured to generate learning support information that supports learning of knowledge provided as at least a part of the group of content based on a result of the analysis.
