Abstract
A data processing device () is provided with: a data base storage region () for storing MSmass spectra of a great number of known compounds in advance; an acquisition unit for acquiring the MSmass spectrum of an unknown compound (); and a score calculation unit () for finding respective scores indicating similarities between the MSmass spectrum of the unknown compound and MSmass spectra of the great number of known compounds. The data processing device () is characterized by being further provided with: an intensity score calculation unit () for classifying the peaks in the MSmass spectrum of the unknown compound and the peaks in the MSmass spectra of the known compounds into intensity scores of several ranks depending on the dimensions of the ion intensities, respectively; and a position score calculation unit () for finding the respective position scores indicating error in the mass-to-charge ratio for each peak, wherein the score calculation unit () adds up the intensity score of each peak in the MSmass spectrum of a known compound, the intensity score of the corresponding peak in the MSmass spectrum of the unknown compound and the position score, and calculates as a score the sum total of the values that have been added up for all peaks.
