Abstract
A classification device includes processing circuitry configured to acquire an operation log related to operation information and identify each operation performed by a user using the operation log, create a vector of each operation based on a co-occurrence relationship between operations identified, calculate a similarity between a predetermined number of operations adjacent to each other in chronological order by using the vector of each operation created, determine a division point of operations by using the similarity calculated and divide a time-series operation into operation sets based on the division point, and classify the operation sets divided into classes based on a number of types of operations common to the operation sets.
