  The present invention relates to an opinion display device, an opinion display method, and a program for displaying opinions of a plurality of people concerning a certain subject.

  How to process and present opinions and proposals gathered from multiple users in an application where multiple users can give opinions and proposals or consensus among multiple users in an open virtual space This may affect the process of mutual understanding and consensus building among users. As a means of promoting mutual understanding and consensus building among multiple users, a method of visualizing the content currently being discussed in order to share it with everyone has been proposed.

  For example, Patent Document 1 proposes a consensus building support system that supports the smooth consensus of all participants in the creation, restoration, and maintenance of the natural environment. In the consensus building support system of Patent Document 1, the entire opinion network and the current network in the site are associated with each other based on a link between key phrases, and are shown as one integrated network. The consensus building support system determines the key phrases that are the core of the overall opinion and the links that are the skeleton of the overall opinion by counting the needs of all participants. Based on this, a network of notable phrases is sought. In addition, refer to the current network and clearly indicate the network position of the key phrase to be noted.

  Further, Patent Document 2 proposes a system for smoothening the discussion by assuming discussions via the Internet and subdividing and rearranging the content of statements. In the technique of Patent Document 2, it is possible to manage the discussion proceeding procedure by selectively specifying different discussion characteristics and types according to the discussion rules registered in advance. It defines the roles of discussion parties such as moderators, panels, interested parties, audiences, etc., and generates and manages discussion information in a hierarchical structure of discussion classification information, sub-topic information, claims, grounds for arguments, and objections. In addition, it is equipped with a special input device that can break down opinions for each detailed issue and register them structurally. Develop interactive defenses against various arguments and opinions by issue, and structurally inquire about these defenses. Analyze all the assertions and objections presented to define the logical structure, correlation, and character between opinions, and based on this, exit logically disagreements and bad opinions. Based on these personality definitions and attack and defense results, we establish a verdict rule that can specify the logical validity of the claim, and based on this rule, we automatically systematically evaluate the suitability of the claim for each detailed case.

  In the present invention, the virtual space is a model in which a real space or a conceptual space is represented by computer data. The actual space is a space that can be an object representing the arrangement of people or objects, and includes, for example, a city, a building, an office, a work place, a warehouse, a conference room, a banquet hall, and a stage. In that case, each virtual space is a model represented by computer data in order to simulate the arrangement of people or objects.

  A conceptual space is a place where elements of a concept are identified by one or more factors and are arranged to visually represent the relationship between them. For example, there are an event occurrence prediction diagram, a factor analysis diagram, a PERT diagram (Program Evaluation and Revue Technique chart). In that case, each virtual space is a model in which those fields are represented by computer data in order to simulate the arrangement of the elements of the concept. The conceptual space is typically represented by a coordinate system having factors as coordinate axes.

  In the present invention, an object is expressed in a virtual space by computer data in order to represent a point where a position in a conceptual space of a person's opinion is mapped to a position in a virtual space corresponding to the conceptual space. It is a model. In the case of an opinion regarding the arrangement of a person or thing in the real space, the opinion is represented by the arrangement of an object corresponding to the person or thing in the virtual space corresponding to the real space. Opinions regarding the arrangement of people or objects in the real space, or the positioning of opinions in the conceptual space are expressed by arranging objects in the virtual space.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of the opinion display system according to Embodiment 1 of the present invention. The opinion display system includes an opinion display device 1 and a terminal 6. The opinion display device 1 and the terminal 6 can communicate with each other via a network (not shown). Although a single terminal 6 is shown as a representative, a plurality of terminals 6 may be connected to a network. The terminal 6 may be a part of the opinion display device 1 or an attached device.

  The opinion display device 1 includes an opinion data input unit 11, an opinion data storage unit 12, an opinion data analysis unit 13, an object generation unit 14, a virtual space / object storage unit 15, a virtual space display generation unit 16, and an object distribution display generation unit 17. Is provided. The opinion data storage unit 12 or the virtual space / object storage unit 15 may be another device connected to the opinion display device 1 via a network.

  The opinion data input unit 11 inputs user opinion data input from the terminal 6. Opinion data is input, for example, in a questionnaire format for answering questions, or by selecting from displayed options. The opinion data input unit 11 associates the date and time at which the opinion data is input, or at least the input order with the opinion data. The opinion data already input may be input via some storage medium or network. Even in this case, it is assumed that the order in which the opinion data is generated is held in some form.

  The opinion data storage unit 12 stores input opinion data. The stored opinion data includes, for example, a code for identifying a user who inputs an opinion, the date and time or order in which the opinion was input (occurred), items and values constituting the opinion, a character string of a sentence representing the opinion, and the like Composed.

  The opinion data analysis unit 13 extracts the value of the coordinate of the opinion data in the virtual space from the input opinion data. The virtual space is a model in which a conceptual space having an opinion attribute as a coordinate axis is expressed by computer data. The value of the coordinate of the opinion data may be a continuous numerical value, or may be a discrete numerical value such as a five-step evaluation. If the opinion data is an arbitrary character string, a keyword of interest is extracted from the character string, and attributes and evaluation data in the subject included in the opinion are set corresponding to the keyword.

  The object generation unit 14 determines the position in the virtual space of the object represented in the virtual space from the coordinate value of the opinion data extracted by the opinion data analysis unit 13. The object is a character string or icon corresponding to the subject of the opinion, or the name or symbol of the user who has input the opinion data. One piece of data representing an object is generated for each opinion data. The date / time or order data when the opinion data is input is given to the object.

  Further, the object generation unit 14 may perform cluster analysis on a set of opinion data to generate an object corresponding to a representative for each cluster. The cluster analysis may take into account the date and time when opinion data was input. That is, changes in the tendency of opinion data can be extracted as a cluster in a time series in which opinion data occurs.

  A virtual space / object storage unit (hereinafter referred to as an object storage unit) 15 includes a configuration of coordinates (attributes) of the virtual space, an object generated by the object generation unit 14, and an object position (including the order of occurrence of opinion data) ( (Coordinate value) is stored.

  The virtual space display generation unit 16 selects a display type of the virtual space from the coordinate configuration of the virtual space stored in the object storage unit 15 and generates display data thereof. For example, a coordinate axis of interest is selected from the coordinate axes of the virtual space, and which is associated with the vertical axis and the horizontal axis is determined. It also determines the scale and range to display. The display type of the virtual space is not limited to a two-dimensional coordinate plane. For example, there can be a perspective view of a three-dimensional coordinate (for example, a 3-D graph), a radar chart, or the like.

  The virtual space display generation unit 16 also determines a method for displaying the temporal change of the opinion data, and generates display data of the virtual space in accordance with the method. For example, the occurrence order of opinion data is set as one coordinate axis on the screen. Examples of the method for displaying the temporal change of the opinion data include a method in which the occurrence time is set as one coordinate in the coordinate space, a method in which the occurrence time is shortened and the coordinate space is displayed as a moving image or a frame advance image, and the occurrence time. There is a method of changing the color and shape of the object for each stage. There are two methods for displaying an object by changing the color and shape of the object, in which the image is changed for each stage of occurrence time, and in which a plurality of stages of the occurrence time are overlapped and displayed in one image.

  The object distribution display generation unit 17 selects an object to be displayed according to the image of the virtual space to be displayed, and generates an image for displaying it. Further, the objects to be displayed are classified and arranged according to the method of displaying the temporal change of opinion data, and an image to be displayed is generated in accordance with each time order. For example, when the virtual space is three-dimensional or more and the coordinates to be displayed are two-dimensional, an image of the object projected on the selected coordinate plane is generated. In addition, a plurality of images are generated for each time order. Alternatively, an image in which the color or shape of the object is changed for each time order is generated.

  The object distribution display generation unit 17 may display an object for each opinion data, or may generate and display an object representing a cluster. In addition, an object for each opinion data and an object representing the cluster can be displayed in an overlapping manner. Or you may display the numerical value which counted the object for every coordinate value with a graph.

  The virtual space display generation unit 16 and the object distribution display generation unit 17 transmit the generated image data to the terminal. Images that display temporal changes in opinion data may be transmitted in sequence, or a plurality of images that follow the time sequence may be transmitted in a batch.

  The terminal 6 includes an input unit 61 and a display unit 62. The input unit 61 receives input of opinion data. Also, a command to display the virtual space and opinion data is input. The display unit 62 displays an image of the virtual space and object distribution sent from the opinion display device.

  FIG. 2 shows an example of display of virtual space and object distribution. The example of FIG. 2 displays the distribution of opinions that predict when a certain event will occur. The horizontal axis represents the year in which the event is expected to occur. The vertical axis represents the frequency of opinion. FIG. 2 shows an information presentation screen 2, a distribution 21 of all data, and a position 22 as a result of collecting opinions. By showing the entire distribution in this way, it can be seen that the opinion is largely divided into two distributions. Further, the change in the shape of the distribution 21 of all data and the change in the position 22 as a result of collecting the opinions are displayed as moving images or frame-by-frame. In the example of FIG. 2, for easy understanding, the distribution 21a at time t-2 and the distribution 21b at time t-1 are displayed with different line types. The distribution change is displayed as a moving distribution.

  FIG. 3 shows examples of different displays of the virtual space and the object distribution. The example of FIG. 3 displays the distribution of opinions that predict when a certain event occurs, as in FIG. Also in FIG. 3, the horizontal axis represents the year in which the event is predicted to occur, and the vertical axis represents the frequency of opinion. In FIG. 3, in the information presentation screen 3, the opinion data distribution 31 at time t-2, the opinion data distribution 32 at time t-1, the opinion data distribution 33 at time t, and A position 34 as a result of collecting opinions is shown. By showing in this way, you can see how the aggregated opinions have changed.

  FIG. 4 shows another display example of the virtual space and the object distribution. The example of FIG. 4 also displays the distribution of opinions that predict when a certain event will occur. Also in FIG. 4, the horizontal axis represents the year in which the event is predicted to occur, and the vertical axis represents the frequency of opinion.

  In FIG. 4, in the information presentation screen 4, a histogram 41 of people who are highly likely to occur around 2050, a histogram 42 of people who are highly likely to occur around 2060, A position 43 as a result of collecting the opinions is shown. As a temporal change, the position and height of the histogram may be displayed as a moving image or frame-by-frame, or the histogram may be displayed with different colors and patterns. In FIG. 4, the histogram at time t−2 is represented by an alternate long and short dash line, and the histogram at time t−1 is represented by a dotted line. By showing in this way, it can be seen whether there are many people who think that event A is likely to occur at any of the two times, and the transition of its distribution.

  FIG. 5 shows another display example of the virtual space and the object distribution. The example of FIG. 5 displays a distribution of opinions that predict when two events A and B will occur. Also in FIG. 5, the horizontal axis represents the year in which the event is predicted to occur, and the vertical axis represents the frequency of opinion.

  In FIG. 5, in the information presentation screen 5, objects 51 </ b> A and 51 </ b> B indicating positions where data is input by each user assuming that the respective events A and B may occur, and positions 52 </ b> A and 52 </ b> B obtained as a result of collecting opinions Show. The object 51A indicates the position where data is input for the event A. The object 51B indicates the position where data is input for the event B. A position 52A indicates a position where opinions are aggregated with respect to the event A. A position 52B indicates a position where opinions are aggregated with respect to the event B. In the example of FIG. 5, the dispersion of the user's opinion is small for the event A, and the opinion is dispersed for the event B in a range exceeding 2060 to 2070.

  In FIG. 5, the change in the distribution of the positions 51 of all data and the change in the position 52 as a result of collecting the opinions are displayed as moving images or frame-by-frame. FIG. 5A shows the object distribution at time t, FIG. 5B shows the object distribution at time t-1, and FIG. 5C shows the object distribution at time t-2. It can be seen how the object distribution has changed in the order of FIGS. 5C, 5B, and 5A. Regarding event A, there is not much change in opinion over time, and regarding event B, there is a change in opinion over time. Here, an example in which the distribution of each time is statically displayed has been described, but a dynamic display method such as tracking each person's opinion and swinging between two points may be used. Further, the positions 52A and 52B obtained as a result of collecting the opinions may be either an average value, a median, or a mode.

  FIG. 6 is a flowchart illustrating an example of the operation of the opinion display device according to the first embodiment. When the opinion data is input and transmitted at the terminal 6, the opinion data input unit 11 inputs the opinion data and registers it in the opinion data storage unit 12 (step S11).

  The opinion data analysis unit 13 inputs the user's opinion data from the opinion data storage unit 12, analyzes the opinion data, and extracts the value of the coordinate of the opinion data in the virtual space (step S12). The object generation unit 14 generates an object represented in the virtual space from the value of the coordinates of the opinion data, and determines the position in the virtual space (step S13). Then, the generated object data is stored in the object storage unit 15.

  When a command to display the opinion distribution is input from the terminal 6 (step S14; YES), the virtual space display generation unit 16 determines the virtual space from the configuration of the virtual space coordinates stored in the object storage unit 15. A display type is selected and the display data is generated (step S15). The object distribution display generation unit 17 selects an object to be displayed according to the virtual space image to be displayed, and generates an image for displaying the object (step S16). Further, the objects to be displayed are classified and arranged according to the method of displaying the temporal change of opinion data, and an image to be displayed is generated in accordance with each time order.

  The virtual space display generation unit 16 and the object distribution display generation unit 17 transmit the generated image data to the terminal, and display the virtual space and the object distribution on the terminal 6 (step S17). When the opinion data is input without terminating the display (step S18; NO), the process returns to step S11 and is repeated from the input of the opinion data.

  If a command for displaying the opinion distribution is not input in step S14 (step S14; NO), it is determined whether the opinion data is input without displaying the virtual space and the object distribution (step S18). When the display is to be ended (step S18; YES), the opinion display process is ended.

  As described above, according to the opinion display device 1 according to the first embodiment, the user can know how the contents of the discussion are changing over time. As a result, users who participated in discussions and discussions from the middle can grasp the transition of opinions.

The opinion data extraction unit 19 extracts the value of the coordinate (attribute) of the opinion data from the arrangement of the input object in the displayed virtual space. At this time, the date and time at which the arrangement of the object is input, or at least the input order is associated with the opinion data. The opinion data extracted by the opinion data extraction unit 19 is stored in the opinion data storage unit 12.

  FIG. 8 shows an example of the object arrangement opinion input screen. The object placement opinion input screen 81 displays a virtual space in which the horizontal axis is the year of birth and the vertical axis is the probability of occurrence, and the objects to be placed in the virtual space. On the screen 81, events B and C are displayed on the right side. The screen 81 also displays the opinion person and the current time. An opinion input person drags and arranges an object at a position where he or she guesses about the year in which the event occurs and its accuracy. FIG. 8 shows a state where an object 82 of event A, which is one of the objects, is arranged in the virtual space. When an “input” button is clicked after the object is arranged, the arrangement of the object is input as an opinion of the user X.

  Operations after the opinion data analysis unit 13 are the same as those in the first embodiment. Since the opinion data extraction unit 19 can extract the coordinates of the opinion data from the arrangement of the objects, the opinion data analysis unit 13 may use the value.

  FIG. 9 is a flowchart illustrating an example of the operation of the opinion display device according to the second embodiment. In the second embodiment, operations for displaying a virtual space and inputting an object arrangement are added. The virtual space display generation unit 16 generates an image of the virtual space and displays it on the display unit 62 of the terminal 6 (step S21).

  When the user arranges an object in the virtual space displayed by operating the terminal 6, the object arrangement input unit 18 inputs the position of the arranged object on the image (step S22). The opinion data extraction unit 19 extracts the values of the coordinates (attributes) of the opinion data from the input object arrangement (step S23). At this time, the date and time at which the arrangement of the object is input, or at least the input order is associated with the opinion data.

  Also, the opinion data analysis unit 13 inputs the user's opinion data from the opinion data storage unit 12, analyzes the opinion data, and extracts the value of the coordinate of the opinion data in the virtual space (step S23). The object generation unit 14 generates an object represented on the virtual space from the coordinate value of the opinion data, and determines a position on the virtual space (step S24).

  The operations from the opinion distribution display determination (step S25) to the display end determination (step S29) are the same as the operations from step S14 to step S18 in FIG.

To do. Here, the weighting of the object includes, for example, changing the size, shape, pattern or color of the object, or a combination thereof.

  Further, the object generation unit 14 may perform cluster analysis on a set of opinion data to generate an object corresponding to a representative for each cluster. Consider weighting for each object when performing cluster analysis. For example, when calculating the center of gravity of an object included in a cluster, a weighted average of the position of the object is taken using a coefficient representing importance.

  The object distribution display generation unit 17 selects an object to be displayed in accordance with the image of the virtual space to be displayed, and generates an image for displaying the object. At that time, a coefficient representing importance is considered. For example, the weighting of the object is performed here, and the size and shape of the object are changed by using a coefficient representing the importance when the object representing the cluster is generated.

  The weighting of the object may change even in the time series of opinion data. The object distribution display generation unit 17 includes a temporal change in a coefficient representing importance when generating an image to be displayed in accordance with a method for displaying a temporal change in opinion data. For example, an image is generated with different weights for each time order.

  The object distribution display generation unit 17 may display an object for each opinion data, or may generate and display an object representing a cluster. In addition, an object for each opinion data and an object representing the cluster can be displayed in an overlapping manner. Or you may display the numerical value which counted the object for every coordinate value with a graph.

  FIG. 11 is a flowchart illustrating an example of the operation of the opinion display device according to the third embodiment. The third embodiment is different from the first embodiment in that importance level input is added, and object weighting and object distribution are weighted and displayed.

  When the opinion data is input and transmitted at the terminal 6, the opinion data input unit 11 inputs the opinion data and registers it in the opinion data storage unit 12 (step S31). The opinion data analysis unit 13 inputs the user's opinion data from the opinion data storage unit 12, analyzes the opinion data, and extracts the value of the coordinate of the opinion data in the virtual space (step S32).

  The object generation unit 14 inputs a coefficient representing the importance of the user corresponding to the opinion data from the importance data storage unit 10 (step S33). Then, an object represented in the virtual space is generated from the coordinate value of the opinion data, the position in the virtual space is determined, and the object is weighted (step S34). The object generation unit 14 stores the generated and weighted object data in the object storage unit 15.

  The operations of opinion distribution display determination (step S35) and virtual space display generation (step S36) are the same as the operations of step S14 and step S15 of FIG. In the object distribution display generation (step S37), the coefficient representing the importance is taken into account. For example, when weighting the object or using the coefficient representing the importance when generating the object representing the cluster, Change the shape.

  The virtual space / object distribution display (step S38) and the display end determination (step S39) are the same as steps S17 and S18 in FIG.

  The coefficient representing the importance may be weighted according to the authority of the user (an opinion input person). In addition, what is determined by a plurality of users under an agreement may be increased in importance. In addition, it is possible to reduce the importance of an opinion that seems to have been decided by looking at the opinions of others, or to lower the importance of the opinion of a user who changes his opinion repeatedly.

  As described above, according to the opinion display device according to the third embodiment, the object of opinion data can be weighted and displayed with the coefficient representing the importance assigned to each user. As a result, it is possible to display how the content of the discussion changes with time, reflecting the origin of the opinion or the process of inputting the opinion.
