<p>PROBLEM TO BE SOLVED: To provide a new method for selecting the subset of data items with high possibility to be referred to at the point of time when newly referring to data by paying attention to the periodicity of the reference of the data items. SOLUTION: In this information processor, this method is for predicting and selecting the subset of the predetermined (n) pieces of the data items as the candidates of the data items to be referred to at the certain point of time from the plural data items of one set. For that, reference history information including a representative reference time interval I(Di) in the past and the latest reference time T(Di) of the last reference is updated/managed for the respective plural data items Di (i=1, 2, 3, 4...), and at the time of referring to an optional data item, the time of the next reference is predicted based on the time interval and the latest reference time for the respective items and high order (n) pieces are selected from the one of which the predicted time is close to the present time.</p> |
