The features of blood pressure surges are classified based on blood pressure information, which is one type of biological information. An information processing apparatus includes a classification unit configured to classify a blood pressure surge determined with reference to time-series data of blood pressure values that change in conjunction with heartbeats, into one or more patterns based on a feature point and a feature amount that characterize the blood pressure surge； and a display unit configured to, upon one of the classified patterns being selected, display a waveform that corresponds to the selected pattern, or display a period in the time-series data to which the waveform corresponds.
