[0083] The determination unit 42 also has an attribute item determination model, and can input attribute information of the recipient user into the attribute item determination model and determine one or more attribute items to be classified based on the score for each attribute item output from the attribute item determination model.

[0084] For example, the determination unit 42 can determine attribute items whose scores output from the attribute item determination model are equal to or greater than a threshold as classification target attribute items, or can determine a predetermined number of attribute items in descending order of the scores output from the attribute item determination model as classification target attribute items. The attribute item determination model is generated using, for example, learning data including, for each user U, information on the attributes of the user U and information on the attribute items selected by the user U.

[0085] Furthermore, the determining unit 42 can determine one or more classification target attribute items based on the type of target content provided by the providing unit 45 in addition to the attributes of the destination user.

[0086] In this case, the determination unit 42 has an item determination table in which one or more attribute items are associated with each combination of the attribute of the destination user and the type of target content, and the classification unit 43 uses this item determination table to determine one or more attribute items to be classified.

[0087] In addition, the determination unit 42 can also determine one or more attribute items to be classified using an attribute item determination model that receives attribute information of the destination user and information on the type of target content as input and outputs a score for each attribute item.

[0088] Furthermore, the determination unit 42 can also determine one or more attribute items to be classified based on the type of target content provided by the providing unit 45, instead of the attributes of the destination user. In this case, the determination unit 42 can also determine one or more attribute items to be classified using an item determination table or an attribute item determination model.

[0089] In addition, when the target content provided by the providing unit 45 is specific content, the determining unit 42 can also determine a plurality of predetermined attribute items as classification target attribute items regardless of the attributes of the recipient user.

[0090] The determining unit 42 can also determine a plurality of groups to be included in the determined group set for each attribute item to be classified, based on at least one of the attribute of the destination user and the type of target content.

[0091] For example, assume that the classification target attribute item determined by the determination unit 42 is the attribute item of age. In this case, the determination unit 42 determines one group from, for example, a group including multiple groups in age ranges of 10 years (for example, groups in ranges such as under teens, teens, 20s, and 30s), a group including multiple groups in age ranges of 20 years (for example, groups in ranges such as under teens, 20s to 30s, and 40s to 50s), etc.

[0092] The determination unit 42 has, for example, an item determination table in which attribute items are associated with each combination of the attributes of the recipient user and a group group, and uses this item determination table to determine multiple groups included in the group group for each attribute item to be classified.

[0093] In addition, the determination unit 42 has a group determination model for each attribute item to be classified, inputs attribute information of the recipient user into the group determination model, and can determine a group for each attribute item to be classified based on the score for each group output from the group determination model.

[0094] The determination unit 42 can also determine the priority of the determined plurality of classification target attribute items based on at least one of the attributes of the destination user and the type of the target content. Such priority is, for example, a display priority, and in this case, a group of classification target attribute items with a higher priority is displayed higher.

[0095] Each of the above-mentioned attribute item determination models and group determination models is, for example, a learning model generated by a GBDT (Gradient Boosting Decision Tree) or a learning model generated by deep learning using a deep neural network (DNN), but is not limited to such examples and may also be a learning model generated by other machine learning methods.

[0096] [4.3.4. Classification section 43] The classification unit 43 classifies each of the multiple comments posted to the target content provided by the provision unit 45 into groups according to the attributes of the posting users.

[0097] For example, the classification unit 43 classifies each of the multiple posted comments into a group according to the attribute of the posting user for each attribute item. For example, when the determination unit 42 determines multiple attribute items to be classified, the classification unit 43 classifies the multiple posted comments into a group according to the attribute of the posting user for each attribute item to be classified determined by the determination unit 42.

[0098] For example, assume that the multiple classification target attribute items determined by the determination unit 42 are gender, age, place of residence, and family structure. In this case, the classification unit 43 classifies each of the classification target attribute items, gender, age, place of residence, and family structure, into groups according to the attributes of the posting user.

[0099] The classification unit 43 classifies the posted comments into groups of the gender of the posting user, such as a male group, a female group, and an unknown group, in terms of the attribute item of gender.

[0100] Furthermore, the classification unit 43 classifies the posted comments into age groups corresponding to the posting users, such as a group of teenagers, a group of people in their twenties, a group of people in their thirties, etc., as a classification based on the attribute item of age.

[0101] Furthermore, the classification unit 43 classifies the posted comments into groups of residences corresponding to the posting user's place of residence, for example, a group of posted comments whose place of residence is in the Kanto region, a group of posted comments whose place of residence is in the Kansai region, a group of posted comments whose place of residence is in a region other than the Kanto region and the Kansai region, etc.

[0102] Furthermore, the classification unit 43 classifies the posted comments into family structure groups corresponding to the family structures of the posting users, such as a group of single posting users, a group of posting users who have a spouse but no children, a group of posting users who have a spouse and children, etc.

[0103] Assume that the attribute items to be classified determined by the determination unit 42 are gender, age, and political ideology. In this case, the classification unit 43 classifies the attribute items of gender, age, and political ideology into groups according to the attributes of the posting user.

[0104] The classification unit 43 classifies the posted comments into groups of political ideology tendencies corresponding to the posting user, as a classification based on the attribute item of political ideology tendencies. The groups of political ideology tendencies are, for example, a group of conservative political ideologies, a group of neutral political ideologies, a group of reformist political ideologies, etc.

[0105] Furthermore, when the determining unit 42 determines a plurality of groups included in each attribute item, the classifying unit 43 classifies the posted comments into the plurality of groups for each attribute item determined by the determining unit 42.

[0106] [4.3.5. Judgment unit 44] The determining unit 44 determines a group according to the attributes of users to whom the target content provided by the providing unit 45 is to be provided.

[0107] For example, the determination unit 44 determines one or more groups from among the multiple groups of attribute items classified by the classification unit 43 as groups corresponding to the attributes of the destination user for each attribute item classified by the classification unit 43.

[0108] The determination unit 44 determines, for each attribute item, a group that matches the attribute of the destination user from among a plurality of groups of attribute items classified by the classification unit 43, as a group according to the attribute of the destination user.

[0109] For example, suppose that the attribute item classified by the classification unit 43 is the attribute item of gender, and the multiple groups of the attribute item of gender are a male group, a female group, and other groups. In this case, the determination unit 44 selects the male group if the gender of the destination user is male, and selects the female group if the gender of the destination user is female.

[0110] Furthermore, it is assumed that the attribute item classified by the classification unit 43 is the attribute item of age, and that the multiple groups of the attribute item of age include a group of teens, a group of twenties, and a group of thirties, etc. In this case, the determination unit 44 selects the group of twenties when the age of the destination user is in his twenties, and selects the group of thirties when the age of the destination user is in his thirties.

[0111] In addition, the judgment unit 44 may have, for example, a group determination table in which a group of each attribute item is associated with each attribute of the destination user, and may determine in such a group determination table that a group associated with the attribute of the destination user is a group according to the attribute of the destination user.

[0112] The determination unit 44 also has a group determination model for each attribute item, and can input attribute information of the destination user to the group determination model and determine a group according to the attribute of the destination user based on the score for each group output from the group determination model. For example, the determination unit 44 determines the group with the highest score output from the group determination model as the group according to the attribute of the destination user.

[0113] Note that, instead of determining one group for each attribute item to be classified as a group corresponding to the attributes of the target user, the determination unit 44 can also determine two or more groups for each attribute item to be a group corresponding to the attributes of the target user. For example, the determination unit 44 can determine a predetermined number of groups in descending order of the scores output from the group determination model as groups corresponding to the attributes of the target user.

[0114] [4.3.6.Providing Department 45] The providing unit 45 provides the content corresponding to the request or information received by the receiving unit 41 to the terminal device 2 that made the request and displays it on the display unit 11 of the terminal device 2, thereby providing the content corresponding to the request or information to the user U of the terminal device 2 that made the request.

[0115] For example, when a content list request is accepted by the accepting unit 41, the providing unit 45 provides the list content corresponding to the content list request to the user U of the requesting terminal device 2 by transmitting the list content including multiple target contents of the type identified by the content list request to the requesting terminal device 2 and displaying it on the display unit 11 of the terminal device 2.

[0116] 7 is a diagram showing an example of list content provided by the providing unit 45 of the information processing device 1 according to the embodiment. The list content 50 shown in FIG. 7 includes a search box 51, a search button 52, a first content column 53, a tab column 54, a second content column 55, and a third content column 56.

[0117] A search keyword is input into the search box 51 by the user U operating the operation unit 12. When the user U operates the operation unit 12 to select a search button 52 with the search keyword input into the search box 51, the information output unit 18 of the terminal device 2 transmits a search query including the search keyword input into the search box 51 to an information providing device (not shown). The information providing device transmits search results according to the search keyword included in the search query to the terminal device 2. The search results are acquired by the information acquisition unit 16 and displayed on the display unit 11 by the display processing unit 17.

[0118] Each content included in the first content column 53, the second content column 55, and the third content column 56 is content that will be transferred to the destination content when selected by user U, and some of the content, for example, displays part of the information included in the destination content.

[0119] When the user U selects a content in the first content column 53, the content to which the selected content is to be transferred is displayed on the display unit 11. The user U can redisplay the list content 50 by selecting the back button or home button displayed on the display unit 11.

[0120] In the second content column 55, a plurality of target contents 57a, 57b, 57c, 57d, and 57e are arranged side by side in the vertical direction. The plurality of target contents 57a, 57b, 57c, 57d, and 57e arranged in the second content column 55 can be switched by selecting a tab included in the tab column 54.

[0121] The third content column 56 includes home button content for transitioning to an initial screen, as well as content for transitioning to destination content when selected by the user U. Hereinafter, when referring to each of the target contents 57a, 57b, 57c, 57d, and 57e without distinguishing them individually, they may be referred to as target content 57.

[0122] When the user U selects one of the multiple target contents 57 included in the second content column 55 by operating the operation unit 12, the information output unit 18 of the terminal device 2 transmits a content request to the information processing device 1, including information identifying the target content 57 selected by the user U.

[0123] The providing unit 45 of the information processing device 1 provides the provided content to the user U by transmitting the provided content in response to the content request to the requesting terminal device 2 and displaying it on the display unit 11 of the terminal device 2. The provided content includes, for example, the target content specified in the content request, comment content including multiple comments on the target content, and a comment report button.

[0124] 8 is a diagram showing an example of provided content provided by the providing unit 45 of the information processing device 1 according to the embodiment. The provided content 60 shown in Fig. 8 includes target content 57 specified in the content request, comment content 61, a comment report button 64, and a link 65. The link 65 is a GUI for returning to the list content 50 shown in Fig. 7.

[0125] The comment content 61 includes posted comment information 62a and 62b corresponding to the target content 57 specified by the content request, and a comment button 63. The comment button 63 is a GUI button for displaying multiple pieces of posted comment information other than the posted comment information 62a and 62b on the display unit 11 of the terminal device 2.

[0126] Each of the posted comment information 62a and 62b includes a posted comment 620, a positive evaluation button 621, a negative evaluation button 622, and a reply comment button 623. Note that the posted comment information 62a and 62b may also include a neutral evaluation button.

[0127] Each posted comment 620 is a posted comment posted for the target content 57 specified by the content request. The positive evaluation button 621 is a GUI (Graphical User Interface) button that a user U who has viewed the posted comment 620 selects when giving a positive evaluation to the posted comment 620, and the number of selected positive evaluation buttons 621 is indicated at a position corresponding to the positive evaluation button 621.

[0128] The negative evaluation button 622 is a GUI button that a user U who has viewed the posted comment 620 selects when they want to give a negative evaluation to the posted comment 620, and the number of negative evaluation buttons 622 selected is indicated at a position corresponding to the negative evaluation button 622.

[0129] The reply comment button 623 is a GUI button for displaying posted comments on the target content 57 specified by the content request, other than the posted comment 620 indicated by the posted comment information 62a and 62b.

[0130] The comment report button 64 is a GUI button for displaying comment-related content including grouped content and comment content including multiple posted comments. For example, by selecting the comment report button 64, the user U can display the comment-related content on the display unit 11 of the terminal device 2.

[0131] The information output unit 18 of the terminal device 2 transmits, as selection information, information for identifying the button selected by the user U from the positive evaluation button 621, the negative evaluation button 622, the reply comment button 623, and the comment report button 64 to the information processing device 1. The receiving unit 41 of the information processing device 1 receives the selection information from the terminal device 2.

[0132] If the received selection information includes information for specifying the positive evaluation button 621 or the negative evaluation button 622, the receiving unit 41 stores the received selection information in the content storage unit 31 and updates the evaluation information in the content table.

[0133] If the selection information received by the receiving unit 41 includes information for identifying the reply comment button 623, the providing unit 45 provides the comment content to the user U by transmitting comment content including multiple posted comments in response to the posted comment corresponding to the reply comment button 623 to the terminal device 2 and displaying the comment content on the display unit 11 of the terminal device 2.

[0134] In addition, if the selection information received by the receiving unit 41 includes information for identifying the comment report button 64, the providing unit 45 provides the comment-related content to the user U by transmitting the comment-related content corresponding to the comment report button 64 to the terminal device 2 and displaying it on the display unit 11 of the terminal device 2.

[0135] The comment-related content includes grouping content and comment content. The grouping content is content that indicates, for each attribute item, a plurality of groups into which a plurality of posted comments have been classified by the classification unit 43.

[0136] 9 is a diagram showing an example of comment-related content provided by the providing unit 45 of the information processing device 1 according to the embodiment. The comment-related content 70 shown in Fig. 9 includes grouping content 71, comment content 72, and a link 76. The link 76 is a GUI for returning to the provided content 60 shown in Fig. 8.

[0137] The comment content 72 includes posted comment information 74a and 74b corresponding to the target content 57 identified by the content request, and a comment button 75. Like the posted comment information 62a and 62b, the posted comment information 74a and 74b include a positive rating button, a negative rating button, and a reply comment button. The posted comment information 74a and 74b may also include a neutral rating button. The comment button 75 is a GUI button for displaying multiple pieces of posted comment information other than the posted comment information 74a and 74b on the display unit 11 of the terminal device 2.

[0138] The grouping content 71 is content that indicates, for each attribute item, a plurality of groups into which a plurality of posted comments have been classified by the classification unit 43, and includes graph content 73a and 73b.

[0139] The graph content 73a is content of a graph by age group showing multiple groups classified according to the attribute item of age, and in the example shown in Fig. 9, it is content of a graph by age group showing the distribution of the number of posted comments by age group from teenagers to people in their 70s. Also, while the graph content 73a shown in Fig. 9 shows the distribution of the number of posted comments by age group using a bar graph, the number of posted comments by age group may also be shown using a different type of graph, such as a pie chart.

[0140] Graph content 73b is a gender graph content showing multiple groups classified according to the attribute item of gender, and in the example shown in Fig. 9, it is a gender graph content showing the distribution of the number of posted comments by gender, male, female, and other gender. Also, graph content 73b shown in Fig. 9 is a graph showing the distribution of the number of posted comments by gender using the size of the circle, but the number of posted comments by gender may be shown using a different type of graph, such as a bar graph or a pie chart.

[0141] The graph contents 73a and 73b are GUI contents, and the user U can select one of multiple groups classified by attribute items to display posted comments posted by a specific posting user.

[0142] For example, when user U views a comment posted by a woman in her twenties, he or she selects, for example, a group for people in their twenties in graph content 73a, and selects, for example, a group for women in graph content 73b.

[0143] When a group included in the graph contents 73a and 73b is selected by the user U, the information output unit 18 of the terminal device 2 transmits information indicating the selected group to the information processing device 1 as selection information.

[0144] For example, suppose that user U selects, for example, a group of people in their twenties in graph content 73a and a group of women in graph content 73b. In this case, information output unit 18 transmits information indicating the group of people in their twenties and the group of women to information processing device 1 as selection information.

[0145] The receiving unit 41 of the information processing device 1 receives selection information from the terminal device 2. When the selection information received by the receiving unit 41 includes information indicating a group selected by the user U, the providing unit 45 provides the new comment-related content 70 to the user U by transmitting the new comment-related content 70 to the terminal device 2 and displaying it on the display unit 11 of the terminal device 2.

[0146] The new comment-related content 70 includes comment content including a plurality of posted comments classified into groups indicated by the selection information received by the reception unit 41, and grouping content 71 in which the groups indicated by the selection information are highlighted.

[0147] For example, if the received selection information includes information indicating a group of people in their twenties and a group of women, the providing unit 45 provides the user U with comment-related content 70 including comment content including multiple posted comments classified into both the group of people in their twenties and the group of women, and grouping content 71 in which the group of people in their twenties and the group of women are highlighted.

[0148] 10 is a diagram showing another example of comment-related content 70 provided by the providing unit 45 of the information processing device 1 according to the embodiment. The comment-related content 70 shown in FIG. 10 includes grouping content 71, comment content 77, and a link 76.

[0149] In the grouping content 71 of the comment-related content 70 shown in Fig. 10, the group of people in their twenties and the group of women are highlighted as groups selected by the user U among the attribute items. This allows the user U to easily understand the groups for each selected attribute item. The groups selected by the user U are highlighted by, for example, varying the color, shading, thickness of the border, etc.

[0150] The comment content 77 includes posted comment information 78a, 78b, and 78c each including a comment posted by a woman in her twenties among a plurality of posting users corresponding to the target content 57 specified by the content request, and a comment button 79.

[0151] The comment button 79 is a GUI button for displaying on the display unit 11 of the terminal device 2 information on posted comments other than the posted comments included in the posted comment information 78a, 78b, and 78c among multiple posted comments, each of which includes a comment posted by a woman in her twenties.

[0152] In this way, by selecting a plurality of groups indicated by the grouping content 71, the user U can easily view posted comments that have been categorized into any of the plurality of groups.

[0153] In the above-described example, when a group of multiple attribute items is selected, the providing unit 45 provides posted comments classified into any of the selected groups of attribute items, but when a group of one attribute item is selected, the providing unit 45 provides posted comments classified into the selected group.

[0154] For example, when a group of people in their twenties is selected, the providing unit 45 provides posted comments categorized into the group of people in their twenties, and when a group of men is selected, the providing unit 45 provides posted comments categorized into the group of men.

[0155] Furthermore, in the above example, the providing unit 45 provides grouping content including a plurality of groups for each of a plurality of attribute items, but it is also possible to provide grouping content for each attribute item.

[0156] For example, the providing unit 45 provides information indicating a plurality of groups in one attribute item among the plurality of attribute items as grouping content. After that, when one or more groups among the plurality of groups in one attribute item are selected, the providing unit 45 provides information indicating a plurality of groups in the remaining one attribute item among the plurality of attribute items as grouping content.

[0157] 11 is a diagram showing an example of changes in comment-related content provided by the providing unit 45 of the information processing device 1 according to the embodiment. Comment-related content 70 shown in (a) of Fig. 11 includes grouping content 71A instead of grouping content 71. Grouping content 71A includes graph content for selecting a group for the attribute item of age.

[0158] When a group is selected by the user U from among the graph contents included in the grouping content 71A, the providing unit 45 provides the comment-related content 70 including the grouping content 71A in which the selected group is highlighted, the grouping content 71B in which no group is selected, and the comment content 77A, as shown in (b) of Fig. 11. In the example shown in (b) of Fig. 11, the comment-related content 70 is shown when a group of people in their twenties is selected.

[0159] Comment content 77A includes posted comment information including posted comments posted by posting users in their twenties among a plurality of posting users corresponding to target content 57 specified by the content request.

[0160] The grouping content 71B includes graph content for selecting a group of the attribute item of gender. When the user U selects one group from the graph content included in the grouping content 71B, the providing unit 45 provides the comment-related content 70 including the grouping contents 71A and 71B in which the selected group is highlighted and the comment content 77, as shown in (c) of Figure 11. The example shown in (c) of Figure 11 shows the comment-related content 70 when the group of people in their twenties and the group of women are selected.

[0161] In the example shown in Figure 11, the grouping content of the attribute item for which the group is selected is included in the comment-related content 70, but the providing unit 45 can also provide comment-related content 70 that does not include the grouping content of the attribute item for which the group is selected.

[0162] In this way, the providing unit 45 can also provide grouping content for each attribute item. When providing grouping content for each attribute item, the providing unit 45 provides the grouping content for each attribute item in descending order of priority determined by the determining unit 42.

[0163] The providing unit 45 can also provide grouping content that combines groups of two or more attribute items. For example, the providing unit 45 can provide grouping content that allows users to select attributes of posting users that combine groups of multiple attribute items, such as a group of women in their twenties and a group of men in their twenties.

[0164] [5. Processing Procedure] Next, a procedure of information processing by the processing unit 22 of the information processing device 1 according to the embodiment will be described. Fig. 12 is a flowchart showing an example of information processing by the processing unit 22 of the information processing device 1 according to the embodiment.

[0165] 12, the processing unit 22 of the information processing device 1 determines whether the target content has been submitted from the uploader device 3 (step S20). If the processing unit 22 determines that the target content has been submitted (step S20: Yes), the processing unit 22 stores the submitted target content in the storage unit 21 (step S21).

[0166] When the processing of step S21 is completed or when it is determined that the target content has not been submitted (step S20: No), the processing unit 22 determines whether or not a comment has been posted (step S22). When it is determined that a comment has been posted (step S22: Yes), the processing unit 22 stores the posted comment in the storage unit 21 (step S23). Then, the processing unit 22 classifies the posted comment into groups according to the attributes of the posting user (step S24).

[0167] When the processing of step S24 is completed or when it is determined that no comment has been posted (step S22: No), the processing unit 22 determines whether a content request or selection information has been accepted (step S25). When it is determined that a content request or selection information has been accepted (step S25: Yes), the processing unit 22 provides the content according to the content request or selection information to the user U by transmitting the content according to the content request or selection information to the terminal device 2 and displaying it on the terminal device 2 (step S26).

[0168] For example, when a group indicated by the grouping content 71 is selected, the processing unit 22 provides comments classified into the selected group from among the multiple groups indicated by the grouping content 71 in the process of step S26.

[0169] When the processing of step S26 is completed or when it is determined that a content request or selection information has not been received (step S25: No), the processing unit 22 determines whether or not it is time to end the operation (step S27). For example, when the power of the information processing device 1 is turned off or when it is determined that an end operation has been performed by operating an operation unit (not shown) of the information processing device 1, the processing unit 22 determines that it is time to end the operation.

[0170] If the processing unit 22 determines that the operation end time has not yet arrived (step S27: No), it proceeds to step S20, and if it determines that the operation end time has arrived (step S27: Yes), it terminates the processing shown in Figure 12.

[0171] [6. Modifications] In the above-described example, the online services provided by the information processing device 1 are online services provided by news sites, shopping sites, auction sites, flea market sites, restaurant introduction sites, review sites, SNS sites, etc. However, the online services are not limited to these examples. The information processing device 1 may also provide online services provided by map providing sites, travel sites, search sites, etc.

[0172] Furthermore, the terminal device 2 can cooperate with the information processing device 1 to execute some or all of the functions of one or more of the acquisition unit 40, the reception unit 41, the determination unit 42, the classification unit 43, the judgment unit 44, and the provision unit 45, and can function as a part of an information processing device having some or all of the functions of one or more of the determination unit 42, the classification unit 43, the judgment unit 44, and the provision unit 45. Note that, hereinafter, a configuration including some or all of the above-described information processing device 1 and the terminal device 2 may be referred to as the information processing device 1.

[0173] The processing unit 15 shown in Figure 3 is realized by a processor such as a CPU or MPU executing various programs (examples of information processing programs) stored in a storage device (e.g., storage unit 14) inside the terminal device 2 using RAM as a working area.

[0174] [7. Hardware Configuration] The information processing device 1 or terminal device 2 according to the above-described embodiment is realized by, for example, a computer 80 configured as shown in Fig. 13. The following description will be given taking the information processing device 1 as an example. Fig. 13 is a hardware configuration diagram showing an example of a computer 80 that realizes the functions of the information processing device 1 according to the embodiment. The computer 80 has a CPU 81, a RAM 82, a ROM (Read Only Memory) 83, an HDD (Hard Disk Drive) 84, a communication interface (I / F) 85, an input / output interface (I / F) 86, and a media interface (I / F) 87.

[0175] The CPU 81 operates and controls each part based on programs stored in the ROM 83 or the HDD 84. The ROM 83 stores a boot program executed by the CPU 81 when the computer 80 starts up, programs that depend on the hardware of the computer 80, and the like.

[0176] The HDD 84 stores programs executed by the CPU 81, data used by such programs, etc. The communication interface 85 receives data from other devices via the network N (see FIG. 2) and sends it to the CPU 81, and transmits data generated by the CPU 81 to other devices via the network N.

[0177] The CPU 81 controls output devices such as a display and a printer, and input devices such as a keyboard and a mouse, via the input / output interface 86. The CPU 81 acquires data from the input devices via the input / output interface 86. The CPU 81 also outputs generated data to the output devices via the input / output interface 86.

[0178] The media interface 87 reads a program or data stored in a recording medium 88 and provides it to the CPU 81 via the RAM 82. The CPU 81 loads the program or data from the recording medium 88 onto the RAM 82 via the media interface 87 and executes the loaded program. The recording medium 88 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or a PD (Phase Change Rewritable Disc), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0179] For example, when the computer 80 functions as the information processing device 1 according to the embodiment, the CPU 81 of the computer 80 executes programs loaded onto the RAM 82 to realize the functions of the processing unit 22. In addition, the HDD 84 stores data in the storage unit 21. The CPU 81 of the computer 80 reads and executes these programs from a recording medium 88, but as another example, the CPU 81 may obtain these programs from another device via the network N.

This enables the information processing device 1 to further facilitate viewing of comments by the user U.

[0188] The information processing device 1 also includes a determination unit 42 that determines a plurality of attribute items to be used for classification by the classification unit 43 based on the attributes of the user to whom the content is provided. The classification unit classifies the content into groups according to the attributes of the posting user for each attribute item determined by the determination unit 42. This allows the information processing device 1 to make it even easier for the user U to view comments.

[0189] The information processing device 1 also includes a receiving unit 41 that receives a selection of one or more groups from among the plurality of groups indicated by the content. The providing unit 45 provides content classified into one of the one or more groups whose selection has been received by the receiving unit 41. This enables the information processing device 1 to easily allow the user U to view comments.

[0190] The information processing device 1 also includes a determination unit 44 that determines a group according to the attributes of the user to whom the content is to be provided. The provision unit 45 provides comments categorized into the group determined by the determination unit 44. This enables the information processing device 1 to make it even easier for the user U to view the comments.

[0191] The plurality of attribute items also include an attribute item indicating the age of the posting user and an attribute item indicating the gender of the posting user. This allows the information processing device 1 to make it easier for the user U to view comments.
