a first calculating unit that obtains a first recommended result, which is the contents to be recommended to the predetermined user, by a first recommendation method;
a second calculating unit that calculates a second recommended result, which is the contents to be recommended to the predetermined user, based on the calculation data by a second recommendation method;
a third calculating unit that obtains a first accuracy rate, which is an accuracy rate of the first recommended result, and a second accuracy rate, which is an accuracy rate of the second recommended result, based on the evaluation data; and
a setting unit that sets a recommendation method for determining the contents to be recommended to the predetermined user by using the first recommendation method and the second recommendation method based on the first accuracy rate and the second accuracy rate.
2. The information processing apparatus according to claim 1 ,
wherein the setting unit sets the recommendation method, by which a higher accuracy rate among the first accuracy rate and the second accuracy rate is obtained, to the recommendation method for determining the contents to be recommended to the predetermined user.
3. The information processing apparatus according to claim 1 ,
wherein the setting unit sets, a combination of the first recommendation method and the second recommendation method according to the first accuracy rate and the second accuracy rate, to the recommendation method for determining the contents to be recommended to the predetermined user.
4. The information processing apparatus according to claim 3 ,
wherein the controller is configured or programmed to function as a determining unit that determines the contents to be recommended to the predetermined user by combining the first recommended result and the second recommended result at a ratio proportional to the first accuracy rate and the second accuracy rate.
5. The information processing apparatus according to claim 3 ,
wherein the controller is configured or programmed to function as a determining unit that determines the number of the contents to be recommended to the predetermined user, which are displayed on a predetermined display device, at a ratio proportional to the first accuracy rate and the second accuracy rate.
6. The information processing apparatus according to claim 4 ,
wherein the controller is configured or programmed to function as a display control unit that, when the contents to be recommended to the predetermined user are displayed on a predetermined display device, displays a reason for recommending the displayed contents by the setting unit on the predetermined display device.
7. The information processing apparatus according to claim 5 ,
wherein the controller is configured or programmed to function as a display control unit that, when the contents to be recommended to the predetermined user are displayed on the predetermined display device, displays a reason for recommending the displayed contents by the setting unit on the predetermined display device.
8. The information processing apparatus according to claim 1 ,
wherein the controller is configured or programmed to function as a threshold value setting unit that sets a threshold value with respect to the first accuracy rate and the second accuracy rate,
in a case that both the first accuracy rate and the second accuracy rate are equal to or greater than the threshold value, the setting unit sets, a combination of the first recommendation method and the second recommendation method according to the first accuracy rate and the second accuracy rate, to the recommendation method for determining the contents to be recommended to the predetermined user, and
in a case that both the first accuracy rate and the second accuracy rate are not equal to or greater than the threshold value, the setting unit sets the recommendation method, by which a higher accuracy rate among the first accuracy rate and the second accuracy rate is obtained, to the recommendation method for determining the contents to be recommended to the predetermined user.
9. The information processing apparatus according to claim 1 ,
wherein the first recommendation method and the second recommendation method are two recommendation methods selected from a recommendation method based on ranking, a recommendation method based on content-based recommendation, and a recommendation method based on collaborative filtering.
10. A control method for an information processing apparatus,
the control method comprising:
storing a usage count of each of a plurality of contents used by each of a plurality of users;
dividing data about the usage count into calculation data for obtaining contents to be recommended to a predetermined user among the plurality of users and evaluation data for obtaining an accuracy rate of a recommended result;
obtaining a first recommended result, which is the contents to be recommended to the predetermined user, by a first recommendation method;
calculating a second recommended result, which is the contents to be recommended to the predetermined user, based on the calculation data by a second recommendation method;
obtaining a first accuracy rate, which is an accuracy rate of the first recommended result, and a second accuracy rate, which is an accuracy rate of the second recommended result, based on the evaluation data; and
performing setting of a recommendation method for determining the contents to be recommended to the predetermined user by using the first recommendation method and the second recommendation method based on the first accuracy rate and the second accuracy rate.
11. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for an information processing apparatus,
the control method comprising:
storing a usage count of each of a plurality of contents used by each of a plurality of users;
dividing data about the usage count into calculation data for obtaining contents to be recommended to a predetermined user among the plurality of users and evaluation data for obtaining an accuracy rate of a recommended result;
obtaining a first recommended result, which is the contents to be recommended to the predetermined user, by a first recommendation method;
calculating a second recommended result, which is the contents to be recommended to the predetermined user, based on the calculation data by a second recommendation method;
obtaining a first accuracy rate, which is an accuracy rate of the first recommended result, and a second accuracy rate, which is an accuracy rate of the second recommended result, based on the evaluation data; and
