INTELLECTUAL PRODUCTIVITY MEASUREMENT DEVICE, INTELLECTUAL PRODUCTIVITY MEASUREMENT METHOD, AND RECORDING MEDIUM

摘要

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.
