The input-prompting part 5 outputs prompting information to the hard disk 103 or display 110 shown in FIG. 1, for example.

CPU101 is generally constituted of many units other than each part shown in FIG. 2, and however, other units are not illustrated for simplicity of description.

The user information acquisition part 3 acquires user information indicating at least either of a subject user's content of opinion e.g. a comment with respect to one or more evaluation subjects and/or a subject user's operation history with respect to one or more evaluation subjects. Besides, the subject user's operation history may be an operation history with respect to the information-processing device 201, or may be an operation history with respect to other devices.

Here, the evaluation subject means all the matters which can be subjects of opinion-issuing. For example, in evaluation subjects, included are an agenda such as a policy, a measure, law, a bill, a rule, an incident, and a news article; a good such as food and a product; service such as service in stores, service in facilities, and service of Web contents; a copyrighted work such as literature, music, a picture, a sculpture, a movie, a theater, and a building; and an opinion and idea of others.

The group determination part 4, based on the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups.

The input-prompting part 5, based on the group to which the subject user belongs, presents to the subject user prompting information, for example, a message for the purpose of inducing the subject user to input a new evaluation subject or content of opinion with respect to a presented evaluation subject which is an evaluation subject presented to the subject user. For example, the input-prompting part 5 determines a prompting information content for every group.

Specifically, the prompting information storage part 8 stores a correspondence relation between each group and a prescribed message which is prompting information. Then, the input-prompting part 5, from among messages stored in the prompting information storage part 8, selects as prompting information a message corresponding to the group to which the subject user belongs.

In addition, for example, in the information-processing device 201, an operation until a subject user inputs a new evaluation subject or content of opinion with respect to a presented evaluation subject is classified into a plurality of stages (phases).

The user information acquisition part 3 acquires user information indicating a subject user's operation history in each phase.

The group determination part 4, based on the operation history indicated by the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups.

In addition, the input-prompting part 5, for every phase, based on a group to which the subject user belongs, presents prompting information for the purpose of inducing the subject user to the next phase.

In more details, the group determination part 4, based on the subject user's operation history in one or more phases to which the subject user has moved before a subject phase, determines a group to which the subject user belongs from among a plurality of groups.

The input-prompting part 5, in the subject phase or a phase to which the subject user moves after the subject phase, presents prompting information to the subject user based on the group to which the subject user belongs.

The phase determination part 6, based on a subject user's operation history, determines a subject user's current phase.

The input-prompting part 5, based on a determination result by the phase determination part 6, presents prompting information for every phase.

[Operation]

Then, an operation of a information-processing device according to the first embodiment of the present invention will be described using the figures In the first embodiment of the present invention, a comment-prompting method according to a first embodiment of the present invention is performed by making the information-processing device 201 operate. Therefore, a description of the comment-prompting method according to the first embodiment of the present invention is substituted by an operation description of the following information-processing device 201. In the following description, FIG. 1 is referred to suitably.

FIG. 3 is a figure showing an example of each phase until comment input or article input in the information-processing device according to the first embodiment of the present invention.

With reference to FIG. 3, in the information-processing device 201, as a criterion of type-classifying of a user, i.e., group classification, for example, a user's behavioral characteristic in each phase is used.

That is, in the information-processing device 201, for example, configured are phases that are: a phase in which a subject user browses a presented evaluation subject; a phase in which a subject user evaluates a presented evaluation subject; a phase in which a subject user inputs content of opinion with respect to a presented evaluation subject; and a phase in which a subject user inputs a new evaluation subject.

Specifically, in the information-processing device 201, a browsing phase, an applause phase (evaluation phase), and a new creation phase are provided. The new creation phase includes a comment creation phase and an article (idea) creation phase.

In the information-processing device 201, the user's behavioral characteristic in each phase is represented by a combination of parameters.

That is, in the information-processing device 201, as a behavioral characteristic in the browsing phase, for example, average time of browsing and the average number of browsing are used. In addition, as a behavioral characteristic in the applause phase, for example, average standby time and the average number of applauding are used. In addition, as a behavioral characteristic in a comment creation phase, for example, average standby time and the average number of input characters are used. In addition, as a behavioral characteristic in an article creation phase, for example, average standby time and the average number of input characters are used.

Specifically, in the browsing phase, the group determination part 4 determines whether a user has a tendency of looking at an evaluation subject only in a short time, or a user has a tendency of looking at it deliberately. In addition, the group determination part 4 determines whether a user has a tendency of looking at only a few evaluation subjects, or a user has a tendency of looking at many evaluation subjects.

In addition, in the applause phase, the group determination part 4 determines whether a user has a tendency of applauding in a short time after having browsed an evaluation subject, or a user has a tendency of applauding after a long time after having browsed an evaluation subject. In addition, the group determination part 4 determines whether a user has a tendency of applauding a few times or a user has a tendency of applauding many times.

In addition, in the comment creation phase, the group determination part 4 determines whether a user has a tendency of inputting a comment in a short time after having browsed an evaluation subject or a user has a tendency of inputting a comment in a long time after having browsed an evaluation subject. In addition, the group determination part 4 determines whether a user has a tendency of inputting a short comment or a user has a tendency of inputting a long comment.

In addition, in the article creation phase, the group determination part 4 determines whether a user has a tendency of inputting an article in a short time after having browsed an evaluation subject or a user has a tendency of inputting an article in a long time after having browsed an evaluation subject. In addition, the group determination part 4 determines whether a user has a tendency of inputting a short article, or a user has a tendency of inputting a long article.

FIG. 4 is a figure showing an example of classification information in the information-processing device according to the first embodiment of the present invention.

With reference to FIG. 4, the classification information storage part 9 stores a group-behavioral characteristic table which is classification information indicating a plurality of groups classified based on each user's behavioral characteristic in each phase. That is, the classification information storage part 9 stores classification information indicating a plurality of groups classified based on a user's content of opinion with respect to an evaluation subject and a user's operation history with respect to the evaluation subject.

The group determination part 4, based on the user information acquired by the user information acquisition part 3, determines a group to which a subject user belongs from among a plurality of groups indicated by classification information stored by the classification information storage part 9

Specifically, in this group-behavioral characteristic table, for example, average time of browsing in a browsing phase of a user belonging to group A is a “small” level and an average number of browsing is a “large” level, and average standby time in the applause phase is a “small” level and the average number of applauding is a “large” level, and average standby time in the new input phase is a “large” level, and the average number of input characters is a “large” level. That is, as a behavioral pattern of a user belonging to group A, a tendency of browsing many articles one after another in a short time, a tendency of inputting many applauses immediately after having browsed articles, and a tendency of inputting a long comment or article in a long time after having browsed articles are acquired as a part of classification information.

In addition, with respect to a user belonging to group B, average time of browsing in the browsing phase is a “small” level and the average number of browsing is a “large” level, and average standby time in the applause phase is a “large” level and the average number of applauding is a “small” level, and average standby time in the new input phase is a “large” level and the average number of input characters is a “small” level.

In addition, with respect to a user belonging to group C, the average time of browsing in the browsing phase is a “small” level and average number of browsing is a “small” level, and the average standby time in the applause phase is a “small” level and the average number of applauding is a “small” level, and the average standby time in the new input phase is a “small” level and the average number of input characters is a “small” level.

Besides, each group's behavioral characteristic in this group-behavioral characteristic table may be acquired from a behavioral characteristic of one user, and may be acquired from behavioral characteristics of a plurality of users.

For example, in the information-processing device 201, as a user's operation history, acquired are the number of input characters of a user's past comment, and standby time after a user has finished browsing of an evaluation subject and has moved to the comment creation phase until inputting a comment. Then, users are classified based on a combination between them, and a message to be presented to a user based on the classification results is determined.

FIG. 5 is a figure showing an example of a message determination table in the information-processing device according to the first embodiment of the present invention.

With reference to FIG. 5, this message determination table indicates each message presented in the comment creation phase, and is a table indicating the average number of input characters of past comments by a user, average standby time until comment input, and a message content corresponding to a combination between them.

In this message determination table, the average number of input characters of a comment is level-classified into “large”, “middle” and “small”, and average standby time until comment input is level-classified into “large”, “middle” and “small”, and nine types of messages corresponding to combinations of each level are indicated. That is, this message determination table indicates nine messages which correspond each to nine classified user groups.

For example, a case where the average number of input characters of a comment is one character to ten characters corresponds to a “small” level, and a case where the average number of input characters of a comment is 11 characters to 50 characters corresponds to a “middle” level, and a case where the average number of input characters of a comment is no less than 51 characters corresponds to a “large” level. In addition, a case where average standby time until comment input is 0 second to 20 seconds corresponds to a “small” level, and a case where average standby time until comment input is 21 seconds to 60 seconds corresponds to a “middle” level, and a case where average standby time until comment input is no less than 61 seconds corresponds to a “large” level.

Then, a message to be presented to a user where average standby time is a “small” level and average number of input characters is a “small” level is “Don't consider too much, and please present a short comment”, and a message to be presented to a user where average standby time is a “small” level and average number of input characters is a “middle” level is “You may not consider too much, but please present a little longer comment”, and a message to be presented to a user where average standby time is a “small” level and average number of input characters is a “large” level is “You may not consider too much, but please present a long comment”.

In addition, a message to be presented to a user where average standby time is a “middle” level and average number of input characters is a “small” level is “considering a little, please present a short comment”, and a message to be presented to a user where average standby time is a “middle” level and average number of input characters is a “middle” level is “considering a little, please present a little longer comment”, and a message to be presented to a user where average standby time is a “middle” level and average number of input characters is a “large” level is “Considering a little, please present a long comment”.

In addition, a message to be presented to a user where average standby time is a “large” level and average number of input characters is a “small” level is “Please consider deliberately. It is O.K. even if a comment is short.”, and a message to be presented to a user where average standby time is a “large” level and average number of input characters is a “middle” level is “Please consider deliberately. Please present a little longer comment.”, and a message to be presented to a user where average standby time is a “large” level and average number of input characters is a “large” level is “Please consider deliberately. Please present a longer comment”.

The prompting information storage part 8 stores this message determination table. The input-prompting part 5, with reference to the message determination table stored in the prompting information storage part 8, selects a message corresponding to a group to which a subject user belongs.

Specifically, the input-prompting part 5, in the case where with respect to a subject user to which prompting information is to be presented, i.e., a user who is browsing an evaluation subject indicated by the information-processing device 201 and has not yet inputted a comment, average standby time is 30 seconds and the past average number of input characters are 40 characters, presents “Considering a little, please present a little longer comment” which is a message where average standby time is a “middle” level and the average number of input characters is a “middle” level.

Besides, a subject of an operation history in this message determination table may be both an evaluation subject which a subject user is browsing and other evaluation subject, and may be either of a presented evaluation subject which a subject user is browsing and/or an evaluation subject of other.

With reference to FIG. 6, first, when a user starts browsing of an evaluation subject, the user information acquisition part 3 acquires user information indicating an operation history or the like of a subject user who is the user having started browsing of the evaluation subject (Step S1).

Next, the group determination part 4, with reference to the group-behavioral characteristic table stored in the classification information storage part 9, based on the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs (Step S2).

Next, the phase determination part 6, based on the subject user's operation history, determines the subject user's current phase (Step S3).

Next, the input-prompting part 5, with reference to the message determination table stored in the prompting information storage part 8, based on a determination result by the group determination part 4 and a determination result by the phase determination part 6, selects a message corresponding to the group to which the subject user belongs and to the subject user's current phase (Step S4).

Then, the input-prompting part 5 presents the selected message to the subject user by displaying it on a screen or the like (Step S5).

When description is carried out using a specific example, the user information acquisition part 3 acquires as user information an operation history which indicates that a user X browsing each article which is an evaluation subject has browsed many articles one after another in a short time in a browsing phase, and has inputted a number of applauses immediately after the article browsing in an applause phase, and stores it in the user information storage part 7 (Step S1).

Next, the group determination part 4, based on the user information stored in the user information storage part 7, determines that a browsing behavior, i.e., behavior in a browsing phase and an applause behavior, i.e., behavior in an applause phase, which are performed by a user X, are behavioral patterns similar to those of the group A in a group-behavioral characteristic table shown in FIG. 4 stored in the classification information storage part 9 (Step S2).

Next, the phase determination part 6, based on the user X's operation history indicated by the user information stored in the user information storage part 7, determines that the user X's current phase is the comment creation phase (Step S3).

Next, the input-prompting part 5, in the comment creation phase, with reference to the message determination table shown in FIG. 5 stored in the prompting information storage part 8, selects a message, corresponding to group A, where average standby time is a “large” level, and the average number of input characters is a “large” level (Step S4), and presents it to the user X (Step S5).

With reference to FIG. 7, in the comment creation phase, an input field F1 for the purpose of a user inputting a comment and a comment field F2 where each user's comment is arranged are displayed on a screen. A scroll bar is provided, for example, in the past comment field F2, and a user can browse each comment.

The input-prompting information presenting part 5, for example, displays on a screen a message, corresponding to group A, where average standby time is a “large” level, and the average number of input characters is a “large” level, i.e., the message “Please consider deliberately. Please present a longer comment”.

By such a message as this, user X's comment input with respect to an evaluation subject is prompted, and the user X inputs a comment.

With reference to FIG. 8, in the article creation phase, an input field F3 for the purpose of a user inputting an idea with respect to the future, and an input field F4 for the purpose of inputting the year where this idea will be realized are displayed on a screen.

The input-prompting information presenting part 5, for example, displays on a screen the message “Don't consider too much, and Please add a simple future idea”.

By such a message as this, a user X's new article input is prompted, and the user X inputs a new article.

With reference to FIG. 9, in the applause phase, the input-prompting information presenting part 5, for example, displays on a screen the message “Please try to applaud immediately after thinking that it is interesting”.

Looking at such a message as this, a user X performs applause input with respect to an evaluation subject, and is induced to a next phase, for example, a new input phase.

In addition, the information-processing device 201, as a criterion of type-classifying of a user, i.e., group classification may be configured to use a move characteristic of each behavior phase by a user, for example.

FIG. 10 is a figure showing other example of classification information in the information-processing device according to the first embodiment of the present invention.

With reference to FIG. 10, the classification information storage part 9 stores a group-behavioral characteristic table which is classification information indicating a plurality of groups classified based on a moving pattern between phases of each user. That is, the classification information storage part 9 stores classification information indicating a plurality of groups classified based on a user's operation history with respect to an evaluation subject.

In this group-behavioral characteristic table, for example, a moving pattern of a user belonging to group A is a pattern where a user moves from a browsing phase to an applause phase, and moves from an applause phase to a new input phase.

In addition, a moving pattern of a user belonging to group B is a pattern where a user moves from a browsing phase to a new input phase. That is, acquired is as apart of classification information a tendency where a user skips an applause phase as a moving pattern of the user belonging to group B and moves directly to a new input phase from a browsing phase.

The user information acquisition part 3 acquires user information indicating a phase move history by a subject user.

The group determination part 4, based on the move history indicated by the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups.

In more details, the group determination part 4, based on the phase move history by the subject user to the subject phase, determines a group to which the subject user belongs from among a plurality of groups.

Specifically, again with reference to FIG. 6, the user information acquisition part 3 acquires as user information an operation history indicating that a user X browsing an evaluation subject has skipped an applause phase and moved directly to a new input phase from a browsing phase, and stores it in the user information storage part 7 (Step S1).

Next, the group determination part 4 determines, based on the user information stored in the user information storage part 7, that a user X's moving pattern is a behavioral pattern similar to that of group B in the group-behavioral characteristic table stored in the classification information storage part 9 shown in FIG. 10 (Step S2).

Next, the phase determination part 6, based on the user X's operation history indicated by the user information stored in the user information storage part 7, determines that a user X's current phase is a browsing phase (Step S3).

Next, the input-prompting part 5, in the browsing phase, with reference to the message determination table stored in the prompting information storage part 8, selects a message corresponding to group B (Step S4), and presents it to the user X, and thereby, induces the user X to the new input phase (Step S5).

Meanwhile, in many cases in a system for the purpose of collecting opinions with respect to a certain content, a few users input a comment positively with respect to this content among users who browse this content, and most users only browse this content and does not input comments. Consequently, a scheme capable of inducing a large number of users' comments is expected.

As compared with this, in the information-processing device according to the first embodiment of the present invention, the user information acquisition part 3 acquires user information indicating at least either of subject user's content of opinion with respect to one or more evaluation subjects and/or a subject user's operation history. The group determination part 4, based on the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups. Then, the input-prompting part 5 presents, to the subject user, prompting information for the purpose of inducing the subject user to input a new evaluation subject or content of opinion with respect to a presented evaluation subject which is an evaluation subject presented to the subject user, based on a group to which the subject user belongs.

That is, in the information-processing device according to the first embodiment of the present invention, type-classifying of an individual is carried out based on a behavioral tendency or the like, and a content for working on the subject user is determined with reference to the past similar behavior type or the like. Thereby, it becomes possible to prompt input of a comment and a new article.

Therefore, based on a minimum configuration comprised of the user information acquisition part 3, group determination part 4 and input-prompting part 5 among each constituent in the information-processing device 201 according to the first embodiment of the present invention, it becomes possible to achieve the object of the present invention to collect opinions from a larger number of users.

In addition, in the information-processing device according to the first embodiment of the present invention, an operation until a subject user inputs a new evaluation subject or content of opinion with respect to a presented evaluation subject is classified into a plurality of stages i.e. phases. Then, the user information acquisition part 3 acquires user information indicating the subject user's operation history in each stage.

By such a configuration as this, it becomes possible to perform more appropriately group determination of a subject user based on an operation history.

In addition, in the information-processing device according to the first embodiment of the present invention, the user information acquisition part 3 acquires user information indicating a move history of a stage by a subject user.

By such a configuration as this, it becomes possible to perform more appropriately group determination of a subject user based on an operation history.

In addition, in the information-processing device according to the first embodiment of the present invention, the group determination part 4, based on the subject user's operation history in one or more stages to which the subject user has moved before a subject stage, or a stage move history by the subject user up to the subject stage, determines a group to which the subject user belongs from among a plurality of groups. Then, the input-prompting part 5, in a stage after the subject stage, presents prompting information to the subject user based on the group to which the subject user belongs.

By such a configuration as this, based on the subject user's operation history in a previous stage, it is possible to determine appropriately a group to which the subject user belongs, and to present more effectively prompting information with respect to the subject user.

In addition, in the information-processing device according to the first embodiment of the present invention, the input-prompting part 5, for every stage, based on a group to which the subject user belongs, presents prompting information for the purpose of inducing the subject user to the next stage. For example, the input-prompting part 5, in the comment creation phase, in addition to prompting information for the purpose of prompting a subject user to input a comment, can also present prompting information so as to induce the subject user to an article creation phase.

In this way, based on a configuration to induce a subject user in incremental steps, the subject user's opinion input can be prompted more effectively.

In addition, in the information-processing device according to the first embodiment of the present invention, the classification information storage part 9 stores classification information indicating a plurality of groups classified based on at least either of user's content of opinion with respect to an evaluation subject and/or an input record of content of opinion by a user. Then, the group determination part 4, based on the user information acquired by the user information acquisition part 3, determines the group to which the subject user belongs from among a plurality of groups indicated by this classification information.

In this way, based on a configuration using results classified in accordance with a prescribed classification rule, a group to which a subject user belongs can be determined by a simple process.

In addition, in the information-processing device according to the first embodiment of the present invention, the input-prompting part 5 determines a prompting information content for every group.

By such a configuration as this, prompting information having a more appropriate content can be presented to a subject user.

In addition, in the information-processing device according to the first embodiment of the present invention, the prompting information storage part 8 stores a correspondence relation between each group and a prescribed message. Then, the input-prompting part 5, from among messages stored in the prompting information storage part 8, selects a message corresponding to a group to which the subject user belongs as the prompting information.

In this way, based on the configuration using the correspondence relation between each group and a prescribed message, it is possible to select a message corresponding to a group to which the subject user belongs by a simple process.

Besides, in the information-processing device according to the first embodiment of the present invention, the input-prompting part 5 is made to be configured to present a message to a subject user as prompting information, and however, it is not limited to this. The input-prompting part 5 may be configured to present, to a subject user, not only a message, but also an image, voice and light or the like as prompting information.

In addition, in the first embodiment of the present invention, the user information acquisition part 3 may be configured to acquire user information indicating both a subject user's operation history in each phase and a phase move history by a subject user, and the group determination part 4, based on the combination between them, may be configured to determine a group to which the subject user belongs from among a plurality of groups.

In addition, in the information-processing device according to the first embodiment of the present invention, a stage where a subject user browses a presented evaluation subject; a stage where a subject user evaluates a presented evaluation subject; a stage where a subject user inputs content of opinion with respect to a presented evaluation subject; and a stage where a subject user inputs a new evaluation subject, are made to be configured, and however, it is not limited to this. For example, a stage where a subject user browses each user's content of opinion with respect to a presented evaluation subject may be further configured.

In addition, if at least any two of these two or more stages are made up to be configured, by dividing a part or all of operations until a subject user inputs a new evaluation subject or content of opinion with respect to a presented evaluation subject into a plurality of stages, it becomes possible to perform group determination of a subject user more appropriately.

In addition, in the first embodiment of the present invention, the stage where a subject user browses a presented evaluation subject may be divided into a stage where a subject user browses a presented evaluation subject in a short time and a stage where a subject user browses it in a long time.

In this case, the input-prompting part 5 presents prompting information to induce a subject user from the stage where the subject user browses a presented evaluation subject in a short time to the stage where the subject user browses a presented evaluation subject in a long time. Specifically, the input-prompting part 5, in the stage where a subject user browses a presented evaluation subject in a short time, presents a message such as “Let's try to look at one article deliberately now”.

By such a configuration as this, in a browsing stage of a presented evaluation subject, it is possible to induce a subject user appropriately toward an input stage of content of opinion or a new evaluation subject.

In addition, in the first embodiment of the present invention, the stage where a subject user browses each user's content of opinion with respect to a presented evaluation subject may be divided into a stage where a subject user browses each user's content of opinion with respect to a presented evaluation subject in a short time and a stage where a subject user browses it in a long time.

In this case, the input-prompting part 5 presents prompting information to induce a subject user from the stage where the subject user browses content of opinion in a short time to the stage where the subject user browses content of opinion in a long time. Specifically, the input-prompting part 5, in the stage where a subject user browses each user's content of opinion with respect to a presented evaluation subject in a short time, presents a message such as “Let's try to look at one comment deliberately now”.

By such a configuration as this, in the browsing stage of each user's content of opinion with respect to a presented evaluation subject, it is possible to induce a subject user appropriately toward an input stage of content of opinion or a new evaluation subject.

In addition, in the information-processing device according to the first embodiment of the present invention, the classification information storage part 9 is made to be configured to store a user's content of opinion with respect to an evaluation subject, and classification information indicating a user's operation history, and however, it is not limited to this.

The classification information storage part 9 may be configured to store classification information indicating a plurality of groups classified based on at least either of a user's content of opinion with respect to an evaluation subject and/or a user's operation history. In addition, classification based on such content of opinion and operation history may be configured using a past actual record, and a manager may configure a classification content in advance.

Next, an other embodiment of the present invention will be described using the figures. It is noted that the same reference character will be is given to the same or corresponding part in the figures, and thus the description will not be repeated.

Second Embodiment

The present embodiment, as compared with the information-processing device according to the first embodiment of the present invention, relates to an information-processing device which controls a presenting timing of prompting information. It is the same as the information-processing device according to the first embodiment except for a content described in the following.

In the information-processing device according to the second embodiment of the present invention, the input-prompting part 5, in the case where a subject user does not move to a new phase even if prescribed time has elapsed after the subject user has moved to a certain phase, presents prompting information to the subject user.

With reference to FIG. 11, first, the input-prompting part 5 detects a timing at which a user has moved to a certain phase (Step S21).

Next, the user information acquisition part 3 acquires user information indicating an operation history or the like of this user (Step S22).

Next, the group determination part 4, with reference to the group-behavioral characteristic table stored in the classification information storage part 9, determines a group to which the user belongs based on the user information acquired by the user information acquisition part 3 (Step S23).

Next, the input-prompting part 5 stands by after the timing at which the user has moved to this phase until a prescribed time elapses (NO at Step S24). Then, the input-prompting part 5, in the case where a user does not move to a new phase even if prescribed time elapses after the timing at which the user has moved to this phase (YES at Step S24), with reference to the prompting information storage part 8, based on the determination result by the group determination part 4, selects a message corresponding to a group to which the subject user belongs (Step S25).

Then, the input-prompting part 5 presents the selected message to a user by displaying it on a screen or the like (Step S26).

In addition, in the information-processing device according to the second embodiment of the present invention, in the new input phase, the input-prompting part 5 presents prompting information to the subject user in the case where a new evaluation subject or content of opinion with respect to a presented evaluation subject is not inputted even if prescribed time has elapsed after a prescribed timing.

With reference to FIG. 12, first, the input-prompting part 5, for example, detects a timing at which a user has finished browsing of an evaluation subject (Step S11).

Here, a timing at which browsing is finished, for example, can be acquired by detecting a timing at which a user has performed an operation to browse a WEB page other than a WEB page on which an evaluation subject is indicated, a timing at which a WEB page on which an evaluation subject is indicated has been closed, or a timing at which a user has moved to a new input phase, i.e., a timing at which a user has performed an operation to browse a WEB page into which an comment or a new article with respect to evaluation subject is to be inputted.

Next, the user information acquisition part 3 acquires user information indicating an operation history or the like of a user who has finished browsing of an evaluation subject (Step S12).

Next, the group determination part 4, with reference to the group-behavioral characteristic table stored in the classification information storage part 9, based on user information acquired by the user information acquisition part 3, determines a group to which the user belongs (Step S13).

Next, the input-prompting part 5 stands by after a timing at which a user has finished browsing of an evaluation subject until a prescribed time elapses (NO at Step S14). Then, the input-prompting part 5, in the case where a user does not input a comment with respect to an evaluation subject even if prescribed time elapses after the timing at which the user has finished browsing of an evaluation subject (YES at Step S14), with reference to the prompting information storage part 8, based on the determination result by the group determination part 4, selects a message corresponding to a group to which the subject user belongs (Step S15).

Then, the input-prompting part 5 presents the selected message to a user by displaying it on a screen or the like.

Besides, the input-prompting part 5, in every prescribed time, for example, in every 10 seconds after above-mentioned each prescribed timing, may be configured to present a message to prompt move to a new phase or new input.

As mentioned above, in the information-processing device according to the second embodiment of the present invention, the input-prompting part 5, in the case where a subject user does not move to anew stage even if prescribed time has elapsed after the subject user has moved to a certain stage, presents prompting information to the subject user.

By such a configuration as this, since prompting information can be presented, at an appropriate timing, to a user who does not move to the next stage, it is possible to prompt further a subject user to move to the next stage.

In addition, in the information-processing device according to the second embodiment of the present invention, the input-prompting part 5, in the case where a new evaluation subject or content of opinion with respect to a presented evaluation subject is not inputted even if prescribed time has elapsed after a prescribed timing, presents prompting information to the subject user.

By such a configuration as this, since prompting information can be presented, at an appropriate timing, to a user who has not performed an input operation, it is possible to prompt further an input operation of the subject user.

Since other configurations and operations are the same as those of the information-processing device according to the first embodiment, detailed descriptions are not repeated here.

Third Embodiment

The present embodiment, as compared with the information-processing device according to the second embodiment, relates to an information-processing device which determines a presenting timing of prompting information for every group. It is the same as the information-processing device according to the second embodiment except for a content described in the following.

In the information-processing device according to the third embodiment of the present invention, the input-prompting part 5, determines for every group a presenting method, for example, a presenting timing of prompting information.

In more details, the input record information acquisition part 1 acquires input record information indicating a record in which each user in a group to which a subject user belongs has inputted content of opinion with respect to one or more evaluation subjects.

The input-prompting part 5, based on the input record information acquired by the input record information acquisition part 1, determines a presenting timing of prompting information.

Specifically, the input record information acquisition part 1 acquires standby time after a prescribed timing until each user starts inputting of content of opinion with respect to one or more evaluation subjects.

The input-prompting part 5, based on each user's standby time in a group to which the subject user belongs, calculates a presenting timing of prompting information.

For example, the input-prompting part 5 creates a frequency distribution of each user's standby time in a group to which the subject user belongs, and based on the created frequency distribution, calculates a presenting timing of prompting information.

FIG. 13 is a figure showing a frequency distribution of standby time until comment input with respect to an evaluation subject.

With reference to FIG. 13, the input record information acquisition part 1 acquires standby time until each user inputs a comment with respect to one or more evaluation subjects, and stores it in the input record information storage part 2.

The input-prompting part 5, for example, for every group of a user in the message determination table shown in FIG. 5, creates a frequency distribution of each standby time stored in the input record information storage part 2.

Specifically, for example, in the case where a subject user belongs to a group where average standby time is a “middle” level and average number of input characters is a “large” level, the input-prompting part 5 creates a frequency distribution of this group.

Then, the input-prompting part 5, since many users belonging to this group inputs a comment at 30 seconds after a browsing finish time of an article which is an evaluation subject, presents a message “Considering a little, please present a long comment” at the timing a little before 30 seconds, for example, at 25 seconds.

That is, the input-prompting part 5 configures the prescribed time in Step S14 of the flow chart shown in FIG. 12 as the time of prescribed time smaller than 30 seconds.

Besides, this frequency distribution may be a frequency distribution of standby time with respect to one evaluation subject, for example, presented evaluation subject, and may be a frequency distribution of standby time with respect to a plurality of evaluation subjects.

In addition, the input-prompting part 5 may have not only a configuration to create a frequency distribution of standby time of a group to which the subject user belongs, but also a configuration to create a frequency distribution of standby time of only a subject user and determine a message presenting timing.

Next, other examples with respect to a determination method of a presenting timing of prompting information will be described.

The input record information acquisition part 1 acquires input record information indicating a record in which each user has inputted content of opinion with respect to other evaluation subjects other than a presented evaluation subject.

The user information acquisition part 3 acquires, as an operation history, user information indicating a record in which a subject user has inputted content of opinion with respect to other evaluation subjects.

The group determination part 4 classifies users into a plurality of groups based on the input record information acquired by the input record information acquisition part 1, and based on the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups.

The input-prompting part 5, based on the group to which the subject user belongs, calculates a presenting timing of prompting information.

Specifically, the input-prompting part 5 classifies users based on a comment log with respect to each article, i.e., determines a user's standby time type, and based on this standby time type, determines a presenting timing of prompting information.

FIG. 14 and FIG. 15 are figures showing a frequency distribution of standby time until comment input of each user who has browsed a certain article.

With reference to FIG. 14, the input record information acquisition part 1 acquires standby time until each user's comment input with respect to an article 1 which is an evaluation subject, and stores it in the input record information storage part 2.

The input-prompting part 5, with respect to the article 1, creates a frequency distribution of each standby time stored in the input record information storage part 2.

The input-prompting part 5, in the frequency distribution of each user who has browsed the article 1, configures as “small” the standby time type of a user whose standby time until comment input is 0 second to 20 seconds, and configures as “middle” the standby time type of a user whose standby time until comment input is 20 seconds to 60 seconds, and configures as “large” the standby time type of a user whose standby time until comment input is no less than 60 seconds.

With reference to FIG. 15, the input record information acquisition part 1 acquires standby time until each user's comment input with respect to an article 2 which is an evaluation subject, and stores it in the input record information storage part 2.

The input-prompting part 5, with respect to article 2, creates a frequency distribution of each standby time stored in the input record information storage part 2.

The input-prompting part 5, in the frequency distribution of each user who has browsed the article 2, configures as “small” the standby time type of a user whose standby time until comment input is 0 second to 10 seconds, and configures as “middle” the standby time type of a user whose standby time until comment input is 10 seconds to 40 seconds, and configures as “large” the standby time type of a user whose standby time until comment input is no less than 40 seconds.

Although not illustrated, in the same way, the input-prompting part 5 creates a frequency distribution also with respect to an article 3 and article 4, and configures a standby time type of “small”, “middle”, or “large”.

Then, the input-prompting part 5, based on the created frequency distribution of each article, and standby time until comment input with respect to each article of the subject user, determines a group to which the subject user belongs, i.e., determines a standby time type of the subject user.

FIG. 16 is a figure showing standby time and a standby time type with respect to each article of the subject user.

FIG. 16 shows that: standby time of a user X who has browsed the article 1 is 40 seconds and a standby time type thereof is “middle”; standby time of a user X who has browsed the article 2 is 15 seconds and a standby time type thereof is “middle”; standby time of a user X who has browsed the article 3 is 20 seconds and a standby time type thereof is “large”; standby time of a user X who has browsed the article 4 is 60 seconds and a standby time type thereof is “small”.

In this case, the input-prompting part 5 determines the “middle” which is the most with respect to each article as the standby time type of the user X.

Besides, the input record information acquisition part 1 may be configured to acquire standby time until each user's comment input with respect to at least one article.

With reference to FIG. 17, the input record information acquisition part 1 acquires standby time until each user's comment input with respect to the article X which is an evaluation subject, and stores it in the input record information storage part 2.

The input-prompting part 5, with respect to the article X, creates a frequency distribution of each standby time stored in the input record information storage part 2, and configures a standby time type of “small”, “middle”, or “large”. Specifically, the input-prompting part 5, in the frequency distribution of each user who has browsed the article X, configures as “small” the standby time type of a user whose standby time until comment input is 0 second to 20 seconds, and configures as “middle” the standby time type of a user whose standby time until comment input is 20 seconds to 60 seconds, and configures as “large” the standby time type of a user whose standby time until comment input is no less than 60 seconds.

Then, the input-prompting part 5, with respect to the user X who is browsing the article X and has not yet inputted a comment, since a standby time type of the user X is “middle”, configures as standby time 40 seconds which is a median, for example, of “middle” types in the created frequency distribution.

That is, the input-prompting part 5 configures the prescribed time in Step S14 of a flow chart shown in FIG. 12 as the median of “middle” types in the frequency distribution of the article X.

Besides, in the third embodiment of the present invention, presenting of prompting information in the comment creation phase has been illustrated and described, and with respect to presenting of prompting information in the article creation phase, the same operation will be also performed.

As mentioned above, in the information-processing device according to the third embodiment of the present invention, the input-prompting part 5 determines a presenting method of prompting information for every group.

By such a configuration as this, it is possible to present prompting information to a subject user more effectively.

In addition, in the information-processing device according to the third embodiment of the present invention, the input-prompting part 5 determines a presenting timing of prompting information for every group.

By such a configuration as this, since it is possible to present prompting information to a subject user at an appropriate timing, a subject user's input operation can be prompted further.

In addition, in the information-processing device according to the third embodiment of the present invention, the input record information acquisition part 1 acquires input record information indicating a record in which each user in a group to which a subject user belongs has inputted content of opinion with respect to one or more evaluation subjects. Then, the input-prompting part 5, based on the input record information acquired by the input record information acquisition part 1, determines a presenting method of prompting information.

In this way, based on a configuration to determine an appropriate presenting method of prompting information using an input record of each user's content of opinion, it is possible to prompt further a subject user's input operation.

In addition, in the information-processing device according to the third embodiment of the present invention, the input record information acquisition part 1 acquires standby time after a prescribed timing until each user starts inputting of content of opinion with respect to one or more evaluation subjects. Then, the input-prompting part 5, based on each user's standby time in a group to which the subject user belongs, calculates a presenting timing of prompting information.

By such a configuration as this, it is possible to acquire an appropriate presenting timing using each user's standby time. Besides, the above-mentioned prescribed timing, for example, may be a timing at which each user starts browsing of each evaluation subject, and may be a timing at which each user finishes browsing of each evaluation subject.

In addition, in the information-processing device according to the third embodiment of the present invention, the input-prompting part 5 creates a frequency distribution of each user's standby time in a group to which the subject user belongs, and calculates a presenting timing of prompting information based on the created frequency distribution.

By such a configuration as this, it is possible to acquire an appropriate presenting timing using a frequency distribution of each user's standby time.

In addition, in the information-processing device according to the third embodiment of the present invention, the input record information acquisition part 1 acquires the input record information indicating a record in which each user has inputted content of opinion with respect to other evaluation subjects other than a presented evaluation subject. The user information acquisition part 3, as an operation history, acquires user information indicating a record in which a subject user has inputted content of opinion with respect to above-mentioned other evaluation subjects. The group determination part 4 classifies users into a plurality of groups based on the input record information acquired by the input record information acquisition part 1, and based on the user information acquired by the user information acquisition part 3, determines a group to which the subject user belongs from among a plurality of groups. Then, the input-prompting part 5 calculates a presenting timing of prompting information based on the group to which the subject user belongs.

By such a configuration as this, with respect to other evaluation subjects other than a presented evaluation subject, an appropriate presenting timing can be acquired using an input record of content of opinion by the subject user and an input record of content of opinion by each user.

Besides, in the information-processing device according to the third embodiment of the present invention, the input-prompting part 5 is made to be configured to determine a message presenting timing for every group, and however, it is not limited to this.

The input-prompting part 5 may be configured to change not only a presenting timing, but also a color, brightness and font or the like of a message as a message presenting method.

In addition, in the information-processing device according to the third embodiment of the present invention, the input record information acquisition part 1 is made to be configured to acquire a user's standby time until comment input as input record information, and however, it is not limited to this. The input record information acquisition part 1 may be configured to acquire, as input record information, a typing speed by a user, i.e., a character input speed by a user, the number of times where a backspace key is pressed, and the number of times where an undo operation is performed, when a user inputs content of opinion.

Since other configurations and operations are the same as those of the information-processing device according to the second embodiment, detailed descriptions are not repeated here.

Fourth Embodiment

The present embodiment, as compared with the information-processing device according to the first embodiment of the present invention, relates to an information-processing device with a classification criterion of user changed. It is the same as the information-processing device according to the first embodiment except for a content described in the following.

In the information-processing device according to the fourth embodiment of the present invention, the user information acquisition part 3 acquires user information indicating attributes of a subject user, and stores it in the user information storage part 7.

In more details, the classification information storage part 9 stores classification information indicating a plurality of groups classified based on attributes of a user.

FIG. 18 is a figure showing an example of a user table in the information-processing device according to the fourth embodiment of the present invention.

With reference to FIG. 18, the user table is a table which indicates individual attributes of each user, and indicates a level of the average number of input characters and average standby time of a comment of each user with respect to each evaluation subject.

In this user table, user A is indicated as follows: age is 25; gender is male; a level of the average number of input characters of a comment with respect to an evaluation subject A is “small”, and a level of average standby time is “middle”; a level of the average number of input characters of a comment with respect to an evaluation subject B is “large”, and a level of average standby time is “small”.

In addition, user B is indicated as follows: age is 25; gender is female; a level of the average number of input characters of a comment with respect to an evaluation subject A is “middle”, and a level of average standby time is “middle”; a level of the average number of input characters of a comment with respect to an evaluation subject B is “middle”, and a level of average standby time is “middle”.

In addition, user C is indicated as follows: age is 30; gender is male; a level of the average number of input characters of a comment with respect to an evaluation subject A is “large”, and a level of average standby time is “small”; a level of the average number of input characters of a comment with respect to an evaluation subject B is “small”, and a level of average standby time is “middle”.
