1. Embodiment 2. FIG. Modified example

<1. Embodiment>
[Configuration Example of Information Processing System 1]
FIG. 1 is a block diagram illustrating an embodiment of an information processing system to which the present technology is applied.

  The information processing system 1 is configured to include a server 11 and clients 12-1 to 12-n. The server 11 and the clients 12-1 to 12-n are connected to each other via the network 13.

  Hereinafter, the clients 12-1 to 12-n are simply referred to as clients 12 when it is not necessary to individually distinguish the clients 12-1 to 12-n.

  The server 11 provides each client 12 with a service for distributing content such as video and music, which is a kind of various items. Further, the server 11 has a function of assisting the user to give a comment to the content or presenting a comment given to the content to the user.

  The client 12 is configured by a device that can use content, such as a personal computer, a portable information terminal, a mobile phone, a smartphone, a video player, and an audio player.

[Configuration Example of Server 11]
FIG. 2 is a block diagram illustrating a configuration example of functions of the server 11.

  The server 11 is configured to include a communication unit 31, an information processing unit 32, and a storage unit 33. The information processing unit 32 is configured to include a feature amount analysis unit 41, a content classification unit 42, a comment analysis unit 43, a user classification unit 44, a selection unit 45, and an output control unit 46. The storage unit 33 is configured to include a content information storage unit 51, a comment information storage unit 52, a user information storage unit 53, and a synonym dictionary 54. Each unit of the communication unit 31 and the information processing unit 32 can access each other. Each unit of the information processing unit 32 can access each unit of the storage unit 33.

  The communication unit 31 communicates with each client 12 via the network 13 and transmits and receives various information and commands related to the content distribution service.

  The feature amount analysis unit 41 analyzes the feature amount of each content used in the content distribution service, and reflects the analysis result in the content feature amount DB (database) stored in the content information storage unit 51.

  FIG. 3 shows a configuration example of the content feature amount DB. The content feature amount DB includes items of a content ID for identifying each content and feature amounts 1 to N. In this example, for example, the value of the feature amount 1 of the content with the content ID 1 is 20, the value of the feature amount 2 is 1, the value of the feature amount 3 is 100,..., And the value of the feature amount N is 0. It has been shown.

  The content classification unit 42 uses the content feature amount DB to classify content used in the content distribution service into a plurality of groups for each content having similar feature amounts. Then, the content classification unit 42 reflects the classification result in the content group DB (database) stored in the content information storage unit 51.

  FIG. 4 shows a configuration example of the content group DB. The content group DB includes two items: a content ID and a group ID for identifying a group to which each content belongs. In this example, for example, it is indicated that a content with a content ID of 1 belongs to a group with a group ID of 3.

  Note that the method of classifying content by the content classification unit 42 is not limited to a specific method, and an arbitrary method can be adopted.

  The comment analysis unit 43 receives a comment given to the content by the user in each client 12 via the network 13 and the communication unit 31. Then, the comment analysis unit 43 stores information regarding the received comment in the comment DB (database) stored in the comment information storage unit 52.

  FIG. 5 is a diagram illustrating a configuration example of the comment DB. The comment DB includes four items: the content ID of the content to which the comment is attached, the user ID for identifying the user to whom the comment is attached, the language used for the comment, and the comment. In this example, for example, it is shown that a user with a user ID of 1 gives a comment “Rhythm is cool” to a content with a content ID of 1 in Japanese.

  In addition, the comment analysis unit 43 analyzes a comment using the synonym dictionary 54 and the like. For example, the comment analysis unit 43 divides the comment into units of words, and extracts characteristic items from words / phrases made up of one or more words constituting the comment. For example, phrases used for content evaluation and impression, phrases with specific parts of speech, and the like are extracted. At this time, a plurality of words may be extracted from one comment, or the whole comment may be regarded as one word.

  Moreover, the comment analysis part 43 totals the usage frequency of the same kind comment for every content based on an analysis result. At this time, the usage frequency may be aggregated for each comment that completely matches, or the comments having similar expressions may be aggregated into one. Then, the comment analysis unit 43 reflects the count result in the comment count DB (database) stored in the comment information storage unit 52.

  FIG. 6 shows a configuration example of the comment tabulation DB. The comment tabulation DB includes four items: a content ID, a language used for the comment, a comment, and a score based on the frequency of use of each comment. In this example, for example, it is indicated that the score of the comment “Rhythm is cool” in Japanese given to the content with the content ID 1 is 7845.

  Here, for example, the frequency of use of each comment may be used as a score as it is, or the number of positive evaluations given by each user may be added to each comment. . Further, for example, only comments whose usage frequency is equal to or higher than a predetermined threshold may be registered in the comment aggregation DB.

  Moreover, the comment analysis part 43 totals the usage frequency of each phrase extracted from the content for every content based on the analysis result. Then, the comment analysis unit 43 reflects the tabulation result in the phrase tabulation DB (database) stored in the comment information storage unit 52.

  FIG. 7 shows a configuration example of the phrase totalization DB. The phrase totalization DB includes four items: a content ID, a language used for the phrase, a phrase, and a score based on the frequency of use of each phrase. In this example, for example, it is indicated that the score of the phrase “cool” in Japanese extracted from the comment given to the content whose content ID is 1 is 26345.

  Here, for example, the frequency of use of each word may be used as a score as it is, or the number of positive evaluations given by each user is added to the comment from which each word is extracted. You may do it. Further, for example, only words having a usage frequency equal to or higher than a predetermined threshold may be registered in the word totaling DB.

  The user classifying unit 44 classifies users who use the content distribution service into a plurality of groups for each similar user based on a predetermined criterion.

  For example, it may be possible to classify each user into a group for each user who has a similar comment tendency, based on the tendency of comments given by each user (for example, the feature amount of a phrase used by each user for comments). It is done. Further, for example, it is conceivable to classify each user into a group for each user with similar behavior based on each user's behavior (for example, content usage history, comment posting history, etc.). Further, for example, it is conceivable to classify each user into a group for each user with similar attributes based on the user attributes (for example, age, sex, occupation, hobby, etc.).

  In addition, you may make it classify | categorize a user using another reference | standard, and may make it classify | categorize a user combining a some reference | standard. Moreover, the method for classifying users is not limited to a specific one, and any method can be employed. Note that the method for classifying users based on the tendency of comments given by each user is described in detail in, for example, Patent Document 1 described above.

  Then, the user classification unit 44 reflects the classified result in the user group DB (database) stored in the user information storage unit 53.

  FIG. 8 shows a configuration example of the user group DB. The user group DB includes two items: a user ID and a group ID for identifying a group to which each user belongs. In this example, for example, it is indicated that a user with a user ID of 1 belongs to a group with a group ID of 1.

  As will be described later, the selection unit 45 uses a content group DB, a comment DB, a comment total DB, a word total DB, a user group DB, and the like to select comments or phrases to be presented to the user together with the content. Then, the selection unit 45 supplies information indicating the selected comment or phrase to the output control unit 46.

  The selection unit 45 selects content to be presented to the user. Then, the selection unit 45 reads information about the selected content from the content information storage unit 51 and the comment information storage unit 52 and supplies the information to the output control unit 46.

  As will be described later, the output control unit 46 uses a comment tabulation DB, a phrase tabulation DB, and the like to prioritize the comment or phrase selected by the selection unit 45 based on the language or score of the comment or phrase, and the communication unit 31.

  Further, the output control unit 46 processes the information related to the content selected by the selection unit 45 as necessary, and supplies the processed information to the communication unit 31.

  The content information storage unit 51 stores information regarding each content used in the content distribution service. For example, in addition to the content feature amount DB in FIG. 3 and the content group DB in FIG. 4, the content information storage unit 51 displays actual content, metadata indicating various attributes of the content, usage status of each content for each region, and the like. Remember.

  The comment information storage unit 52 stores information related to comments given to each content. For example, the comment information storage unit 52 stores the above-described comment DB of FIG. 5, the comment total DB of FIG. 6, the word total DB of FIG.

  The user information storage unit 53 stores information regarding each user who uses the content distribution service. For example, in addition to the above-described user group DB in FIG. 8, the user information storage unit 53 stores each user's attributes and each user's action history (for example, content usage history).

  The synonym dictionary 54 includes a synonym dictionary for each language used in an area where the content distribution service is provided.

[Configuration example of client 12]
FIG. 9 is a block diagram illustrating a configuration example of functions of the client 12.

  The client 12 is configured to include a communication unit 71, a playback unit 72, an output control unit 73, an output unit 74, and an input unit 75.

  The communication unit 71 communicates with each server 11 via the network 13 and transmits and receives various information and commands related to the content distribution service.

  The playback unit 72 receives content from the server 11 via the network 13 and the communication unit 71 and plays back the received content. The playback unit 72 supplies playback data obtained as a result of playback to the output control unit 73.

  The output control unit 73 receives information to be displayed to the user and information to be displayed together with the reproduction of the content, such as information related to the content and comments given to the content, from the server 11 via the network 13 and the communication unit 71. Further, the output control unit 73 controls display of moving images and still images, output of audio, and the like in the output unit 74 based on the reproduction data. Further, the output control unit 73 controls display of various types of information received from the server 11 on the output unit 74.

  The output unit 74 includes, for example, various display devices such as a display and various audio output devices such as a speaker and an audio output terminal.

  The input unit 75 is configured by various input devices such as a keyboard, a mouse, a touch panel, and a microphone. The input unit 75 supplies information and commands input by the user to the reproduction unit 72 and the output control unit 73.

[Processing of information processing system 1]
Next, processing of the information processing system 1 will be described with reference to FIGS. 10 to 17.

(Process when adding comments to content)
First, with reference to the flowchart of FIG. 10, a process when a user gives a comment to content will be described.

  In this process, for example, the user uses the input unit 75 of the client 12 to perform an operation for adding a comment to the content being displayed or reproduced, and the command is output from the input unit 75. Started when supplied to the unit 73.

  Hereinafter, in this process, a user who gives a comment is referred to as an active user, and a content to which a comment is given is called a target content.

  In step S <b> 1, the client 12 transmits information regarding the target content, the active user, and the language setting. Specifically, the output control unit 73 transmits information including the content ID of the target content, the user ID of the active user, and the language currently set in the client 12 (hereinafter referred to as a client setting language) to the communication unit. It transmits to the server 11 via 71.

  Here, the client setting language is set to be used for presenting character information such as a comment in software (for example, a browser, an operating system, etc.) for using the content distribution service by the client 12, for example. It is a language. The client setting language is not limited to one type, and a plurality of client setting languages can be set.

  In step S <b> 2, the communication unit 31 of the server 11 receives information regarding the target content, active user, and language setting from the client 12 via the network 13. The communication unit 31 supplies the received information to the selection unit 45 and the output control unit 46.

  In step S3, the selection unit 45 selects input candidates to be presented to the active user. Here, the input candidates are comments or phrases that are presented so as to be selectable in order to support input when a comment is given to the target content, as will be described later with reference to FIG.

  For example, the selection unit 45 extracts content (its content ID) belonging to the same group as the target content from the content group DB of FIG. 4 as similar content. Then, the selection unit 45 extracts the comments given to the target content or similar content and the words extracted from those comments from the comment total DB of FIG. 6 and the word total DB of FIG. Thereby, comments and phrases suitable for being added to the target content are extracted.

  Moreover, the selection part 45 extracts the user (its user ID) which belongs to the same group as an active user from a user group DB of FIG. 8 as a similar user. And the selection part 45 extracts the phrase extracted from the comment which the active user or the similar user gave in the past from the extracted comment and phrase using comment DB etc. of FIG. To do. As a result, comments and phrases that are likely to be used by active users are extracted.

  Then, the selection unit 45 supplies the finally remaining comments and phrases to the output control unit 46 as input candidates to be presented to the active user.

  At this time, only one of a comment or a phrase may be selected as an input candidate.

  In step S4, the output control unit 46 prioritizes input candidates based on the input candidate scores and language.

  For example, the output control unit 46 sets a weight for a predetermined language (hereinafter referred to as a priority language) to be larger than a weight for other languages, and multiplies or adds the set weight to the score of each input candidate. Thus, the priority of each input candidate is set.

  Then, the output control unit 46 extracts, for example, input candidates having a priority higher than a predetermined threshold or a predetermined number of input candidates having higher priority as input candidates to be finally presented to the active user. Further, the output control unit 46 sets the presentation order of the selected input candidates in order of priority. At this time, input candidates to be presented to the active user may be limited to only comments and phrases in the priority language, or comments and phrases in languages other than the priority language may be included.

  As a result, comments and phrases with high scores are preferentially presented as input candidates. Therefore, general comments and phrases, popular comments and phrases, comments and phrases used for a wide range of contents, etc. are preferentially presented as input candidates.

  On the other hand, special comments and phrases are excluded from the input candidates. For example, comments and phrases that are specific to a specific user, such as those based on personal experiences and those that deviate from general sensitivity, are excluded. Also, comments and phrases that are specific to a specific region or group, such as those based on local topics or using special terms used in some regions and groups, are excluded.

  In addition, comments and phrases in the priority language are preferentially presented as input candidates.

  Here, an example of a priority language setting method will be described.

  For example, a language other than the client setting language may be set as the priority language. As a result, comments and phrases in languages other than the client setting language are preferentially presented as input candidates. As a result, it becomes easy for the active user to add a comment using a language other than the client setting language, for example, a language other than the native language, to the target content.

  Conversely, the client setting language may be set as the priority language. As a result, comments and phrases in the client setting language are preferentially presented as input candidates. As a result, it becomes easy for the active user to add a comment using a client setting language, for example, a native language, to the target content.

  Further, for example, the active user may be able to set the priority language separately from the setting of the client setting language. Thereby, the active user can arbitrarily designate a priority language, and as a result, it becomes easy to give a comment using a desired language to the target content.

  Note that the priority language may be set in advance by the active user or when a comment is given, for example. Alternatively, it may be set at both timings. A plurality of priority languages may be set.

  Further, for example, the active user may designate a specific area instead of a specific language, and set the language of the area (for example, a native language or a standard language) as the priority language. For this specific region, it is possible to designate not only one country but also, for example, a region including a plurality of countries or a partial region of the country.

  Further, instead of a specific language or region, a language that satisfies a specific condition or a language in a region that satisfies a specific condition may be set as a priority language. Here, an example of conditions for setting the priority language will be described.

  For example, it is conceivable to set a language in which the number of comments assigned to the target content is from the top to a predetermined order, or a language in which the number of comments is a predetermined threshold or more as the priority language. Such a language can be detected using, for example, the comment DB of FIG. As a result, comments and phrases in a language that is often given to the target content, that is, comments and phrases in a more commonly used language for the target content are preferentially presented as input candidates. become.

  In addition, for example, it is conceivable to set a language (for example, a native language or a standard language) in a region closely related to the target content or the genre to which the target content belongs as the priority language. Here, the region closely related to the target content or the genre to which the target content belongs is, for example, a region where the target content or the genre to which the target content belongs is produced or a popular region. Such a region can be detected based on, for example, metadata of each content stored in the content information storage unit 51, a usage situation for each region, or the like. As a result, comments and phrases in a language in a region closely related to the target content or the genre to which the target content belongs are preferentially presented as input candidates.

  It is expected that the amount and quality of the comments given by the user are higher in the region closely related to the target content or the genre to which the target content belongs than in other regions. For example, comments on content belonging to the hip-hop genre are expected to be higher in quantity and quality from comments given by users in the United States, the birthplace of hip-hop, than comments given by Japanese users . Accordingly, it is expected that comments and phrases in such local languages will be more expressive and appropriate than comments and phrases in other languages. As a result, the user can widen the range of expression, and it becomes easy to give an appropriate comment that matches his sensitivity.

  In addition, a predetermined number of regions from the top of the content distribution service provided by the server 11 or a language in a region where the number of users is equal to or greater than a predetermined threshold (for example, a native language or a standard language) is set as a priority language. It is possible to do so. Such a region can be detected based on, for example, the attributes of each user stored in the user information storage unit 53. As a result, local language comments and phrases with a large number of users of the content distribution service are preferentially presented as input candidates. Thereby, comments and phrases in a language used by more users are preferentially presented as input candidates.

  These conditions may be set by, for example, an active user, or may be set by the server 11 regardless of the intention of the active user.

  In addition, for example, the above-described priority language setting method may be selected by the active user, or may be automatically selected on the server 11 side. A plurality of setting methods may be used in combination.

  In step S5, the server 11 transmits input candidates. Specifically, the output control unit 46 generates input candidate information including finally remaining input candidates and their presentation order, and transmits the input candidate information to the client 12 of the active user via the communication unit 31.

  In step S <b> 6, the communication unit 71 of the client 12 receives input candidate information from the server 11 via the network 13. The communication unit 71 supplies the received input candidate information to the output control unit 73.

  In step S <b> 7, the output unit 74 presents input candidates under the control of the output control unit 73.

  FIG. 11 shows an example of a screen for inputting a comment on the target content displayed on the client 12. In this screen, a comment input field 101, an evaluation input field 102, and a send button 103 are displayed.

  The comment input field 101 is an area for inputting a comment to be given to the target content.

  The evaluation input field 102 is an area for inputting a five-step evaluation for the target content.

  The send button 103 is a button for confirming the comment input in the comment input field 101 and the evaluation input in the evaluation input field 102 and transmitting it to the server 11.

  For example, when the active user uses the input unit 75 to place a cursor (not shown) in the comment input field 101, the list box 104 for presenting the input candidates selected by the server 11 in the set presentation order or A list box 105 is displayed on the screen.

  The list box 104 shows an example in which words / phrases extracted from comments already added to the target content are presented as input candidates. On the other hand, the list box 105 shows an example in the case where a comment already given to the target content is presented as an input candidate. Of course, comments and phrases may be mixed and presented as input candidates.

  In this example, Japanese is set as the client setting language, and an example in which comments or phrases in a language other than Japanese are preferentially presented as input candidates is shown.

  In step S8, the input unit 75 receives an input of a comment. Then, the input unit 75 supplies information indicating the comment input by the active user to the output control unit 73. The output unit 74 displays the input comment under the control of the output control unit 73.

  At this time, the active user can create a comment using the presented input candidate, or can create a comment without using the input candidate. The active user can also create a comment by adding another character string to the input candidate, or by changing or deleting a part of the input candidate.

  In step S9, the client 12 transmits a comment. Specifically, when the active user presses the send button 103 on the screen of FIG. 11 using the input unit 75, the input unit 75 notifies the output control unit 46 that the send button 103 has been pressed. . The output control unit 46 transmits comment information including the content ID of the target content, the user ID of the active user, and the input comment to the server 11 via the communication unit 31.

  Thereafter, the client 12 ends the process.

  In step S <b> 10, the communication unit 31 of the server 11 receives comment information from the client 12 via the network 13. The communication unit 31 supplies the received comment information to the comment analysis unit 43.

  In step S11, the comment analysis unit 43 analyzes the comment. For example, the comment analysis unit 43 uses the synonym dictionary 54 and the like to divide the comment into words by an arbitrary method, and extracts a characteristic phrase composed of one or more words. At this time, a plurality of words may be extracted from one comment, or the whole comment may be regarded as one word.

  In step S12, the comment analysis unit 43 updates the database. Specifically, the comment analysis unit 43 registers information on a new comment given to the target content by the active user in the comment DB of FIG.

  Further, the comment analysis unit 43 uses the synonym dictionary 54 to search for a comment similar to the new comment from the comment tabulation DB of FIG. And when the comment similar to a new comment is found, the comment analysis part 43 adds one score of the similar comment. On the other hand, when a comment similar to the new comment is not found, the comment analysis unit 43 registers information related to the new comment in the comment tabulation DB.

  Further, the comment analysis unit 43 uses the synonym dictionary 54 to search for a new phrase extracted from the new comment from the phrase totalization DB of FIG. Then, when a phrase similar to the new phrase is found, the comment analysis unit 43 adds one score for the similar phrase. On the other hand, when a phrase similar to the new phrase is not found, the comment analysis unit 43 registers information related to the new phrase in the phrase totalization DB.

  In addition, when an active user selects a comment or a phrase from input candidates presented, the score of the comment or phrase in the comment tabulation DB or the phrase tabulation DB is 1 regardless of whether or not it is included in the final comment. One may be added.

  Thereafter, the client 12 ends the process.

  As described above, the user can easily input an appropriate comment in the language of another country. As a result, for example, the user can easily communicate with the user who uses a language other than the native language.

(Comment ranking presentation process)
Next, a comment ranking presentation process executed by the information processing system 1 will be described with reference to the flowchart of FIG.

  In this process, for example, the user uses the input unit 75 of the client 12 to designate one of the contents being displayed or reproduced, and to perform an operation for displaying the comment ranking of the designated content. This is started when the command is supplied from the input unit 75 to the output control unit 73.

  Hereinafter, in this process, the user who operates the client 12 and views the comment ranking is referred to as an active user, and the content for which the comment ranking is displayed is referred to as target content.

  In step S101, the client 12 requests transmission of comment ranking. Specifically, the output control unit 73 transmits a content ranking transmission request signal for requesting transmission of the comment ranking of the target content to the server 11 via the communication unit 71, including the content ID of the target content.

  In step S <b> 102, the communication unit 31 of the server 11 receives a content ranking transmission request signal from the client 12 via the network 13. The communication unit 31 supplies the received content ranking transmission request signal to the selection unit 45.

  In step S103, the selection unit 45 extracts comments given to the target content from the comment tabulation DB of FIG. Further, the selection unit 45 extracts the score and language of the extracted comment from the comment tabulation DB of FIG. The selection unit 45 supplies the extracted comment and information indicating the score and language of each comment to the output control unit 46.

  In step S104, the output control unit 46 generates a comment ranking. Specifically, the output control unit 46 generates the comment ranking by arranging the comments extracted by the selection unit 45 in descending order of scores.

  In step S105, the server 11 transmits the comment ranking. Specifically, the output control unit 46 generates comment ranking information including the comments extracted by the selection unit 45 and the rank and score of each comment. Then, the output control unit 46 transmits the generated comment ranking information to the client 12 of the active user via the communication unit 31.

  In step S <b> 106, the communication unit 71 of the client 12 receives comment ranking information from the server 11 via the network 13. The communication unit 71 supplies the received comment ranking information to the output control unit 73.

  In step S <b> 107, the output unit 74 presents the comment ranking under the control of the output control unit 73.

  FIG. 13 shows an example of a comment ranking display screen.

  In this example, in the comment field 121 on the left side of the screen, comments given by each user to each content used in the content distribution service are displayed in time series from the top to the newest. In addition to the comment, the name of the user who gave the comment, date and time, content name, artist name, evaluation of the content, and the like are displayed.

  In the balloon 122, the comment ranking of the target content designated by the active user is displayed. In this example, the comment ranking of the song 4 of the artist 4 is displayed. In the balloon 122, the title (the previous comment ranking (all)) is displayed at the top, and the comments for the target content (music 4) are displayed in order of score.

  In step S108, the client 12 receives a setting relating to the language of the comment to be presented. That is, the active user uses the input unit 75 to input settings related to the language (priority language) of the comment displayed in the comment ranking, and the input unit 75 supplies information indicating the setting contents to the output control unit 46.

  Here, an example of a priority language setting method will be described.

  For example, a specific language can be set as the priority language. At this time, a plurality of languages may be set as priority languages.

  Conversely, for example, a language excluded from the priority language may be set. Accordingly, in this case, a language other than the set language is set as the priority language. At this time, a plurality of languages may be set.

  Also, for example, as in the case of the process described above with reference to FIG. 10, a condition is specified, and a language that satisfies the specified condition or a language in a region that satisfies the specified condition is set as the preferred language. Also good.

  In step S <b> 109, the output control unit 73 transmits setting information indicating the priority language setting content to the server 11 via the communication unit 71.

  In step S <b> 110, the communication unit 31 of the server 11 receives setting information from the client 12 via the network 13. The communication unit 31 supplies the received setting information to the output control unit 46.

  In step S111, the output control unit 46 changes the comment ranking based on the setting content. Specifically, first, when a condition for setting a priority language is specified, the output control unit 46 uses the information stored in the storage unit 33 to prioritize the language that satisfies the specified condition. Set the language. Then, the output control unit 46 changes the comment ranking of the target content by rearranging only the comments in the priority language among the comments assigned to the target content in descending order of score.

  In step S112, the comment ranking information related to the changed comment ranking is transmitted from the server 11 in the same manner as in the process of step S105.

  In step S113, the comment ranking information related to the changed comment ranking is received by the client 12 in the same manner as the processing in step S106.

  In step S114, the changed comment ranking is presented in the client 12 in the same manner as in step S107.

  Thereby, for example, comments in the priority language among the comments assigned to the target content are displayed in the score 122 from the top in the balloon 122 of FIG.

  Thereafter, each time the priority language is changed, the processes of steps S108 to S114 are repeatedly executed.

  If the priority language is not changed, the processes in steps S108 to S114 are not executed.

  As described above, the user can easily browse a comment having a higher score among comments in a desired language given to the content.

(Content list presentation process)
Next, content list presentation processing executed by the information processing system 1 will be described with reference to the flowchart of FIG.

  In this process, for example, when the user performs an operation for displaying a desired content list using the input unit 75 of the client 12 and the command is supplied from the input unit 75 to the output control unit 73. Be started.

  The type of content list is arbitrary. For example, a list such as a hit chart provided by the server 11, a playlist created by each user of the content distribution service, a list of content that matches the conditions specified by the user, and the like are assumed. Is done.

  Hereinafter, in this process, a user who operates the client 12 and browses the content list is referred to as an active user.

  In step S201, the client 12 requests transmission of a content list. Specifically, the output control unit 73 transmits a content list request signal for requesting transmission of the content list designated by the active user to the server 11 via the communication unit 71.

  In step S <b> 202, the communication unit 31 of the server 11 receives a content list transmission request signal from the client 12 via the network 13. The communication unit 31 supplies the received content list transmission request signal to the selection unit 45.

  In step S203, the selection unit 45 extracts information and comments regarding the content included in the list. Specifically, the selection unit 45 extracts information such as the content ID, title, and artist name of the content included in the list specified by the active user from the content information storage unit 51. Moreover, the selection part 45 extracts the comment and score provided to each content in the list from the comment aggregation DB of FIG. Then, the selection unit 45 supplies information related to the content in the list, and comments and scores for each content in the list to the output control unit 46.

  In step S204, the output control unit 46 extracts a comment having a higher score for each content in the list. That is, the output control unit 46 extracts, for each content in the list, a comment having a score from the top to a predetermined rank from among the comments assigned to each content.

  In step S205, the server 11 transmits a content list and a comment. Specifically, the output control unit 46 generates content list information including information on the content in the list and a comment extracted for each content. Then, the output control unit 46 transmits the generated content list information to the client 12 of the active user via the communication unit 31.

  In step S206, the client 12 receives the content list and the comment. That is, the communication unit 71 of the client 12 receives content list information from the server 11 via the network 13. The communication unit 71 supplies the received content list information to the output control unit 73.

  In step S207, the output unit 74 presents the content list together with comments under the control of the output control unit 73.

  FIG. 15 shows an example of a content list display screen. In this example, an example is shown in which the top songs in the rankings of hit charts in the United States are presented as a content list.

  In the content list area 141, the contents included in the content list are displayed in order from the top according to the order in the list. For each content, an image representing the content (for example, an album jacket including the content (music)) and an artist name are displayed.

  Also, comments with higher scores among the comments assigned to each content in the list are displayed in balloons 142a to 142c.

  In step S208, the setting regarding the language of the comment to be presented is accepted as in the process of step S108 of FIG. Thereby, the priority language which is the language of the comment presented with the content list is set.

  Note that a method similar to the processing in step S108 in FIG.

  FIG. 16 shows an example of a method for setting a specific language as a priority language. In addition to the screen of FIG. 15, a list box 151 is displayed on the screen of FIG. In the list box 151, a list of language candidates that can be set as the preferred language is displayed. The active user can easily set the priority language by selecting a desired language from the languages in the list box 143.

  In step S <b> 209, the output control unit 73 transmits setting information indicating the setting content of the priority language to the server 11 via the communication unit 71.

  In step S <b> 210, the communication unit 31 of the server 11 receives setting information from the client 12 via the network 13. The communication unit 31 supplies the received setting information to the output control unit 46.

  In step S211, the output control unit 46 extracts a comment to be presented based on the setting content. Specifically, first, when a condition for setting a priority language is specified, the output control unit 46 uses the information stored in the storage unit 33 to prioritize the language that satisfies the specified condition. Set the language. And the output control part 46 extracts the comment from a top to a predetermined order | rank from the comment by the priority language provided to the content in a content list.

  In step S <b> 212, the output control unit 46 transmits the extracted comment to the client 12 via the communication unit 31.

  In step S <b> 213, the communication unit 71 of the client 12 receives the extracted comment from the server 11 via the network 13. The communication unit 71 supplies the received comment to the output control unit 73.

  In step S <b> 214, the output unit 74 changes the comment to be presented under the control of the output control unit 73. Thereby, for example, the comments displayed in the balloons 142a to 142c in FIG. 15 are changed to comments in the priority language designated by the active user.

  Thereafter, each time the priority language is changed, the processes in steps S208 to S214 are repeatedly executed.

  If the priority language is not changed, the processes in steps S208 to S214 are not executed.

  As described above, the user can view a comment having a higher score in each language among comments assigned to the content in the content list while switching the language. Thereby, the user can enjoy, for example, comparing a comment in the native language with a comment in another language.

  It should be noted that the sensitivity to content does not differ greatly depending on the country or race, with some exceptions. For this reason, it is assumed that the content of a comment given to each content becomes more similar as the score becomes higher regardless of the language. Therefore, the user can easily understand how comments in their native language are expressed in multiple languages by displaying comments with higher scores while switching languages.

  FIG. 17 shows a modification of the content list display screen. In this example, information indicating the language of comments for each content in the content list is transmitted from the server 11, and the comments are displayed separately for each language in the client 12.

  Specifically, in the content list area 161, as in the content list area 141 of FIG. 14, the contents included in the content list are displayed in order from the top according to the order in the list.

  In the balloons 162a to 162c, among the comments given in English by the American user to the contents in the list, those having higher scores are displayed.

  In the balloons 163a to 163c, among the comments given in Japanese by the Japanese user to the contents in the list, those having higher scores are displayed.

  The button 164 is used to scroll the balloon display in the horizontal direction and display a comment in a language different from the comment currently displayed on the screen.

  Thereby, the active user can compare the comments in a plurality of languages at a glance.

  As described above, the information processing system 1 assists the user in browsing the comment presented together with the content in the language of another country or adding the comment to the content in the language of the other country. can do.

<2. Modification>
Hereinafter, modifications of the above-described embodiment of the present technology will be described.

[Variation 1: Variation of Comment or Phrase Selection Method and Prioritization Method]
In the above description, an example has been shown in which only comments or phrases given to the target content or similar content and given by the active user or similar user are presented as input candidates, but either condition is omitted. You may do it. In other words, only comments or phrases given to the target content or similar content may be presented as input candidates, or only comments or phrases given by the active user or similar users may be presented as input candidates. . Alternatively, the processing of the selection unit 45 may be omitted, and the output control unit 46 may prioritize all comments or phrases.

  In the above description, an example in which commonly used general comments and phrases are preferentially presented as input candidates has been shown, but for example, comments that are prominently used in the target content compared to other content Or words may be preferentially presented as input candidates. This is because such comments and phrases are considered to significantly represent the unique characteristics of the target content.

  Furthermore, for example, in the comment ranking presentation process in FIG. 12 and the comment list presentation process in FIG. 14, only the comments given by the active user or a user similar to the active user are extracted and presented in the same manner as the process in FIG. 10. You may make it do.

  For example, the output control unit 46 of the server 11 may prioritize comments or phrases to be presented to the user based on only the language without considering the score.

[Modification 2: Modification of processing sharing]
In the above description, an example in which the server 11 prioritizes comments or phrases to be presented to the user has been described. However, it may be performed on the client 12 side.

  For example, all the comments or phrases selected by the selection unit 45 may be transmitted to the client 12, and the output control unit 73 of the client 12 may prioritize the same as the output control unit 46 of the server 11.

  Further, for example, the server 11 and the client 12 may share the priorities. For example, the server 11 may extract a comment or phrase whose score is equal to or greater than a predetermined threshold, the client 12 may prioritize based on language, and the comment or phrase may be presented to the user based on the prioritization.

[Modification 3: Modification of a target to which a comment is added]
Also, this technology is not only for the entire content, but also when specifying a part of the content and giving a comment, or viewing a comment given to a part of the content. Can be applied.

  Furthermore, in addition to the music and videos described above, this technology can add comments to various contents using characters, sounds, images, etc., such as books, games, software, websites, news, advertisements, etc. This can be applied when viewing the attached comments.

  The present technology can also be applied to a case where a comment is given to an item other than the content, for example, a user on various products or a social service, or a given comment is viewed.

[Modification 4: Other Modifications]
In addition, in the above, an example in which a comment or a phrase in a specified region or a region satisfying a specified condition is given priority is shown. For example, regardless of the language to be used, those regions (hereinafter referred to as a priority region) May be preferentially presented.

  Here, the comment given in the priority area is, for example, a comment given by a user belonging to the priority area, a comment transmitted from the client 12 in the priority area, or both. In addition, the user belonging to the priority area is, for example, a user whose registered address or work place is in the priority area, a user whose birth place or nationality is in the priority area, or both. Furthermore, the phrase given in the priority area is, for example, a phrase made up of one or more words constituting a comment given in the priority area.

  Furthermore, in the example of the comment ranking and content list described above, an example is shown in which comments in all languages are first presented to the user. However, only comments in the preferred language may be presented from the beginning.

  Further, when only one of the comment or the words constituting the comment is presented to the user, the creation of either the comment aggregation DB of FIG. 6 or the word aggregation DB of FIG. 7 is omitted. It is possible.

  In addition to the above-described example, the present technology can be applied to any case where a comment is given to an item or a comment or a phrase extracted from the comment is presented together with the item.
