PROBLEM TO BE SOLVED: To provide a method capable of supplying additional information necessary and sufficient for satisfying predetermined pattern recognition performance, to a discriminator simultaneously with a pattern. SOLUTION: In an additional information determination method in regard to the recognition method for determining a category to which each pattern belongs from among a plurality of categories, based on the pattern recognition result of a pattern and additional information corresponding to each pattern, the additional information determination method makes a computer execute the following processes: a process of acquiring a confusion matrix having each element constituted of each probability of being decided as belonging to each category including a true category when each pattern has been pattern recognized; a process for inputting target recognition performance; a code definition process for determining code definition so as to satisfy the target performance being input corresponding to the code of the additional information to be added to the pattern concerned for the true category of each pattern, by referring to the confusion matrix; and a process for outputting the code definition as additional information.
