If the second data are found to exist within the first data, then the updating part updates the first data using the second data; if the second data are not found to exist within the first data, then the updating part adds the second data to the first data. ## Claims ### Claim 1 A method of operating an information processing apparatus including a memory device storing instructions, the method comprising: (a) causing at least one processor to execute the instructions to store at least one of a plurality of preferences of a user; (b) causing the at least one processor to execute the instructions to extract at least one of a plurality of keywords of a plurality of contents; (c) causing the at least one processor to execute the instructions to store the extracted keyword of the content; (d) causing the at least one processor to execute the instructions to select at least one of the plurality of contents based on a comparison of the extracted keyword and the stored preference of the user; and (e) causing the at least one processor to execute the instructions to delete the extracted keyword as a recommended reason. ### Claim 2 (depends on 1) The method of claim 1, which includes causing a display device to display, to the user, recommendation information based on the selected content. ### Claim 3 (depends on 2) The method of claim 2, which includes causing the at least one processor to execute the instructions to select the displayed recommendation information based on data corresponding to the user. ### Claim 4 (depends on 1) The method of claim 1, which includes wherein the plurality of keywords includes: (a) a first keyword having a first keyword ID; and (b) a second keyword having a second keyword ID. ### Claim 5 (depends on 4) The method of claim 4, which includes causing a display device to display, to the user, the first keyword based on the first keyword ID. ### Claim 6 (depends on 4) The method of claim 4, which includes causing a display device to suppress display, to the user, of the second keyword based on the second keyword ID. ### Claim 7 (depends on 4) The method of claim 4, wherein: (a) the first keyword having the first keyword ID is associated with a first flag; and (b) the second keyword having the second keyword ID is associated with a second flag. ### Claim 8 (depends on 7) The method of claim 7, which includes causing a display device to display, to the use, the first keyword having the first keyword ID based on the first flag. ### Claim 9 (depends on 7) The method of claim 7, which includes causing a display device to suppress display, to the use, of the second keyword based on the second flag. ### Claim 10 An information processing apparatus comprising: at least one processor; at least one memory device storing instructions which when executed by the at least one processor, cause the at least one processor to: (a) store at least one of a plurality of preferences of a user; (b) extract at least one of a plurality of keywords of a plurality of contents; (c) store the extracted keyword of the content; (d) select at least one of the plurality of contents based on a comparison of the extracted keyword and the stored preference of the user;

and (b) a second keyword having a second keyword ID. ### Claim 14 (depends on 13) The information processing apparatus of claim 13, wherein when executed by the at least one processor, the instructions cause a display device to display, to the user, the first keyword based on the first keyword 1D. ### Claim 15 (depends on 13) The information processing apparatus of claim 13, wherein when executed by the at least one processor, the instructions cause a display device to suppress display, to the user, of the second keyword based on the second keyword ID. ### Claim 16 (depends on 13) The information processing apparatus of claim 13, wherein: (a) the first keyword having the first keyword ID is associated with a first flag; and (b) the second keyword having the second keyword ID is associated with a second flag. ### Claim 17 (depends on 16) The information processing apparatus of claim 16, wherein when executed by the at least one processor, the instructions cause a display device to display, to the user, the first keyword having the first keyword ID based on the first flag. ### Claim 18 (depends on 16) The information processing apparatus of claim 16, wherein when executed by the at least one processor, the instructions cause a display device to suppress display, to the user, of the second keyword based on the second flag. ### Claim 19 A non-transitory computer-readable medium storing instructions structured to cause an information processing apparatus to: (a) store at least one of a plurality of preferences of a user; (b) extract at least one of a plurality of keywords of a plurality of contents; (c) store the extracted keyword of the content; (d) select at least one of the plurality of contents based on a comparison of the extracted keyword and the stored preference of the user; and (e) delete the extracted keyword as a recommended reason. ### Claim 20 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the instructions are further structured to cause a display device to display, to the user, recommendation information based on the selected content. ### Claim 21 (depends on 20) The non-transitory computer-readable medium of claim 20, wherein the instructions are further structured to cause the information processing apparatus to select the displayed recommendation information based on data corresponding to the user. ### Claim 22 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the plurality of keywords includes: (a) a first keyword having a first keyword ID; and (b) a second keyword having a second keyword ID. ### Claim 23 (depends on 22) The non-transitory computer-readable medium of claim 22, wherein when executed by the at least one processor, the instructions cause a display device to suppress display, to the user, of the second keyword based on the second keyword ID.
