<P>PROBLEM TO BE SOLVED: To identify, in messages that are not associated with other messages, a candidate of an association key for associating the messages with other messages. <P>SOLUTION: An information processing method includes: a step of extracting messages including attribute values of a first attribute and the appearance time of each message from a message storage unit for storing messages including attribute values of one or plural attributes and the appearance time of each message associated with each other; a step of using the extracted data to calculate, for each attribute value of the first attribute, an existing period that is a difference between the earliest appearance time and the latest appearance time among the appearance time of the messages including the attribute value; a step of determining whether a rate of the existing period shorter than a predetermined period to the calculated existing periods is equal to or more than a predetermined threshold; and a step of storing data indicating that the first attribute is a candidate of an association key in a data storage unit when it is determined that the rate is equal to or more than the predetermined threshold. <P>COPYRIGHT: (C)2012,JPO&INPIT |
