<p><P>PROBLEM TO BE SOLVED: To provide a method and a system for evaluating a trend analysis system. <P>SOLUTION: The device for evaluating a trend analysis system as a first embodiment to solve the problem comprises: an acceptable value input part for receiving acceptable values of false positives in which data which is irrelevant is judged as relevant, and acceptable values of false negatives in which data which is relevant is judged as irrelevant; and an accuracy rate calculation part for calculating the accuracy rate of the system, comprising a weight determination part for reading the accuracy data showing correctly whether there is a relation between the data of the existing data aggregate stored in the storage device from the storage device, and determining the weight to the number of the false positives of the system and the weight to the number of the false negatives from the acceptable values of the false positives and the acceptable values of the false negatives using the accuracy data, and a calculation part for calculating the accuracy rate of the system from the number and the weight of the false positives, the number and the weight of the false negatives, and the total number of the data. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
