摘要： When there are no evaluation values from a user who has evaluated both contents X and Z, an indirect similarity calculation unit 32 of an arithmetic processing unit 30 of an information processing center 10a indirectly calculates the similarity between the contents X and Z using evaluation values of a content Y whose evaluation value is present from a user who has evaluated both the contents X and Y and whose evaluation value is present from a user who has evaluated both the contents Y and Z. A predicted evaluation value calculation unit 33 calculates a predicted evaluation value from a user who has not evaluated either of the contents X and Z using the similarity between the contents X and Z calculated by the indirect similarity calculation unit 32 and the evaluation values of the contents X and Z. Thus, it is possible to calculate the predicted evaluation values of the contents X and Z which are not directly calculable. Therefore, it becomes possible to further expand the range of contents whose evaluation values are predictable through collaborative filtering.

摘要： Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

摘要： Movement histories of a vehicle are registered appropriately in a database. A point specification unit specifies a geographical base of a user as a point serving as a nucleus of behavior of the user. When the need arises to delete a movement history stored in the database, a deletion subject data determination unit specifies a movement history having a low degree of relatedness to the geographical base of the user. A data deletion unit then deletes the movement history specified by the deletion subject data determination unit from the database. As a result, behavior histories having a high utility value to the user are held preferentially in the database.
