Abstract:
1. An information processing comprising: a CPU; and a memory; wherein said CPU carries out processing which comprising: an its own-segment memorizing unit that memorizes its own segment, the own segment being at least on segment among each segment made by dividing a range of a key into a plurality of segments so as to make the segments neighbor with each other, the key being generated about at least two attribute names using an attribute name and an attribute value, based on a predetermined order relation and being of a size-comparable form; and a judgment unit that judges whether a key generated from an attribute name and an attribute value being included in the own-segment or not; a reception unit that receives event information, the event information including an attribute name and an attribute value; a segment information transfer unit that, when an attribute name having a frequency included in the received event information being no smaller than a predetermined value is existing among the attribute names, transmits an end segment to another information processing device storing a segment neighboring the end segment, the end segment being a divided segment of the own segment and being a segment including a lower limit or an upper limit; a segment information receiving unit that receives a segment neighboring its own segment from another information processing device; and a processing object information storage unit that updates its own-segment memorizing unit using one of or both of the transmitted end segment and a segment received by the segment information receiving unit.
