<p>Activity information obtainer (10a) of intellectual productivity measurement device (100) obtains activity information representing an activity. Event information obtainer (10b) obtains information representing an event and including a time at which the event occurs. Evaluation obtainer (4) obtains a subjective evaluation. Short-term-context input section (11a) generates a short-term context from the activity information. Long-term-context input section (11b) extracts a long-term context from event information. Model generator (5) generates, using a mapping function from a direct sum space of the space of the short-term context and the space of the long-term context to the space of the subjective evaluation, an estimation model that is a parameter of the mapping function in such a way that values reflecting the short-term context and the long-term context enter within the range of the subjective evaluation. Intellectual productivity calculator (6) calculates an intellectual productivity using the estimation model.</p> |
