Causal inference system, causal inference method, and program

Abstract

To provide a causal inference system with which it is possible to estimate a medicine effective to the mental health of a user.SOLUTION: According to one embodiment of the present invention, a causal inference system is provided. This causal information system includes a processor. The processor is configured to execute a registration step, a change amount calculation step, and a first inference step. In the registration step, drug information including at one of the commodity name of an over-the-counter drug or a prescribed drug that a user takes and the component contained in the over-the-counter drug or the prescribed drug is registered as drug data together with the date of registration. In the change amount calculation step, a change amount of the user's mental health value from the date of registration is calculated. The mental health value indicates the degree of the user's metal health state. In the first inference step, the causal relationship between the over-the-counter drug or the prescribed drug and the mental health value is inferred on the basis of the change amount.SELECTED DRAWING: Figure 1
