Claim 0:
1. A server for classifying a plurality of mental states of a user, comprising:
a service platform; and
a mental state classification platform,
wherein the service platform is configured to:
provide a questionnaire corresponding to each of the plurality of mental states to a terminal of a user, and receive an answer of the user to the questionnaire from the terminal;
receive a face image generated by photographing a face of the user while the user inputs the answer to the questionnaire for each of the plurality of mental states in the terminal of the user;
enable the terminal to display the face image including at least a middle of a forehead and both cheeks of the face of the user on the user interface so that the user can recognize his/her appearance while inputting the answer to the questionnaire through the user interface of the terminal; and
transmit the answer received from the user and the face image to the mental state classification platform,
wherein the mental state classification platform is configured to:
execute a first algorithm to obtain a first numerical value indicating a possibility that the user corresponds to each of the plurality of mental states based on the answer received from the terminal,
extract heart rate variability (HRV) data of the user based on the face image received from the terminal;
execute a second algorithm to obtain a second numerical value indicating a possibility that the user corresponds to each of the plurality of mental states based on the extracted HRV data;
execute a third algorithm to obtain a third numerical value indicating a possibility that the user corresponds to each of the plurality of mental states based on the first numerical value and the second numerical value;
and generate a mental state classification result report indicating the third numerical value,
wherein each of the first numerical value and the second numerical value includes a severity of the mental state of the user, and
wherein the third algorithm is configured to set a weight to be reflected in the third numerical value to each of the first numerical value and the second numerical value and obtain the third numerical value indicating a final mental state classification result from the first numerical value and the second numerical value based on the weight.
