  Hereinafter, an embodiment of a contribution estimation device according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference symbols, without redundant description.

  FIG. 1 shows a contribution estimation device 10 according to the present embodiment. The contribution estimation device 10 is a device (system) that estimates the contribution of a user who has performed a predetermined activity to a predetermined group or organization. In the present embodiment, the contribution estimation device 10 estimates the contribution of the user to the local community. Activities that contribute to the local community include activities that improve the local community, such as littering (garbage collection) and greetings. The group or organization to be contributed is not limited to the local community, but may be a company or the like. Further, the activities of the user relating to the contribution are not limited to those described above.

  The contribution degree estimated by the contribution degree estimation device 10 is used, for example, for giving an incentive (reward) to the user. Specifically, the user may be given points that can be used as currency (for example, electronic money, regional currency (virtual currency)) according to the degree of contribution. Also, what is given to the user is not limited to points, but may be a discount ticket, a right to receive a service, or the like. In addition, by presenting the ranking of the contribution degree to the user, the user may be given a sense of accomplishment that the contribution activity has been performed. By using the degree of contribution as described above, activities for contributing to the local community can be activated. Note that the calculated contribution may be used for purposes other than the above.

  The contribution degree estimation device 10 estimates the contribution degree of the user based on the history of the declaration (report) related to the activity as described later. The contribution degree estimation device 10 is realized by, for example, a server device. Further, the contribution degree estimation device 10 may be realized by a plurality of server devices, that is, a computer system. The contribution estimation device 10 can transmit and receive information to and from an external device 20 which is a device used by a user via a communication network such as a mobile communication network or the Internet. The contribution degree estimation device 10 transmits and receives information according to the present embodiment, such as the information according to the declaration, to and from the external device 20.

  The external device 20 is specifically a terminal such as a mobile phone, a smartphone, or a PC (personal computer). The external device 20 is usually carried for each user. The functions of the external device 20 according to the present embodiment, which will be described later, may be realized by a report application that is a dedicated application (application) installed in the external device 20. When the report application is used, an account for each user for using the report application is generated. In order to prevent the same user from creating a plurality of accounts, the same user may be detected by telephone number authentication or the like. Log in with the account and use the report application. The account can be used as a user identifier as described later. The details will be described together with the function of the contribution estimation device 10. Note that the function according to the present embodiment may be realized by means other than the report application.

  Subsequently, the function of the contribution estimation device 10 according to the present embodiment will be described. As shown in FIG. 1, the contribution estimation device 10 includes a report information acquisition unit 11, an objectivity calculation unit 12, and a contribution estimation unit 13.

  The report information acquisition unit 11 is a functional unit that acquires report information indicating that the reporter reports that the implementing party has performed an activity. The declaration information includes information indicating the filer and the implementing party. In addition, the declaration information may include information indicating an activity performed by the implementing party.

  The declaration information acquisition unit 11 receives and acquires declaration information from the external device 20, for example. The transmission of the report information to the contribution degree estimation device 10, that is, the report of the activity, may be performed by the party performing the activity itself, or may be performed by a party other than the party performing the activity. In the case where the reporting party transmits the report information by itself, the reporting party pertaining to the activity is transmitted from the external device 20 after the party performing the activity. If the reporting information is transmitted by a party other than the party performing the activity, the declarant actually confirms the activity of the implementing party in the real world by seeing the activity of the implementing party, etc. It is transmitted from the device 20. The declaration information acquisition unit 11 acquires a plurality of declaration information as described later in order to appropriately estimate the contribution degree. Note that the acquisition of the declaration information may be performed by any method other than the above.

  FIG. 2 shows an example of a table including report information. In the table shown in FIG. 2, the information in the columns of the filer, the implementing party, and the activity type is information included in the report information. The information of the filer and the implementing party is, for example, the identifier of the user who is the filer and the implementing party. The identifier of the user is, for example, assigned in advance to each user. Specifically, the account of the report application described above can be used as the identifier. The activity type information is information indicating the content of the activity performed by the implementing party.

  The input of the declaration information in the external device 20 may be performed in a unified input format using the report application. For example, a screen for inputting the declaration information shown in FIG. 3 is displayed by the report application, and information is input and transmitted to the screen by a user operation. When information is input, the information may be selected by a pull-down menu in order to prevent the writing from fluctuating. It should be noted that the reason that there is no reporter column in the display of FIG. 3 is that the information of the reporter using the external device 20 is stored in the report application in advance. If there is no such function, it may be possible to input information of the filer.

  As shown in FIG. 3, the declaration information includes, in addition to the above information, implementation time information (for example, date and time) indicating the time at which the activity was performed, and implementation location information (for example, latitude and longitude) indicating the position. Or a character string indicating the location) or a photograph (image) indicating the status of the activity. As the execution position information, position information indicating the position of the external device 20 acquired by the GPS (global positioning system) function, or position information included in Exif (Exchangeable image file format) information attached to the photograph is used. You may.

  In addition, as described below, the declaration information transmitted by a certain user to the contribution degree estimation device 10 may be used to input the declaration information by another user. When a certain user transmits the report information to the contribution estimation device 10, another user can refer to the report information. For example, the declaration information can be displayed by an arbitrary external device 20. FIG. 4 shows an example of the displayed declaration information. FIG. 4A shows report information relating to a report by a user who is the implementing party (the implementing party and the reporter (declarer) are the same, and photographs before and after the activity are posted). FIG. 4 (b) shows report information relating to a report by a user other than the implementing party (the implementing party and the reporter are different, and only photos after the activity are shown). When a user other than the filer confirms that the activity is actually being performed, the user presses a button provided on the display (a button described as “Thank you” in the figure). With this pressing as a trigger, the external device 20 of the other user transmits the report information in which the reporter of the displayed report information is the other user to the contribution estimation device 10. By such a mechanism, a plurality of users can easily declare the same activity.

  Further, for example, as shown in FIG. 5, the location where the activity was performed may be displayed on a map based on the implementation location information included in the declaration information. In this display, when the displayed activity is selected, each information of the declaration information may be referred to.

  The reporting information acquisition unit 11 specifies (extracts) reporting information relating to the same activity from the plurality of the reporting information acquired. Specifically, the declaration information acquisition unit 11 transmits information related to the activity of the declaration information, specifically, the identifier of the user of the implementing party, information indicating the activity type, implementation time information, and implementation location information (that is, the reporter Information other than the user's identifier) to identify the report information related to the same activity. The reporting information acquisition unit 11 specifies information in which all of these pieces of information match each other as reporting information relating to the same activity. Note that there is a possibility that there is an error in the time and position for each piece of report information. Therefore, the time and the position may be the same if they are within a predetermined range. Further, as long as the mode does not use the execution time information and the execution position information, the comparison of these pieces of information may not be performed.

  For example, when new declaration information is acquired, the declaration information acquisition unit 11 determines whether the acquired declaration information is the declaration information relating to the same activity as the past declaration information. The reporting information acquisition unit 11 determines that the acquired reporting information is not reporting information relating to the same activity as past reporting information, that is, if the reporting information is reporting information relating to a new activity, A new activity identifier different from past declaration information is set. If the report information acquisition unit 11 determines that the acquired report information is report information relating to the same activity as any of the past report information, the report information acquisition unit 11 adds the same report information as the past report information relating to the same activity. Set the activity identifier.

  When acquiring a plurality of pieces of reporting information on the same activity by the same filer, the reporting information acquisition unit 11 may delete one of the pieces of reporting information as duplicate reporting information. The aggregation of the report information, that is, the setting and deletion of the activity identifier of the report information may be performed after the calculation of the objectivity by the objectivity calculation unit 12 described later.

  The declaration information acquired by the declaration information acquisition unit 11 is stored in the contribution degree estimation device 10 and used by the objectivity calculation unit 12 and the contribution degree estimation unit 13.

  The objectivity calculation unit 12 is a functional unit that calculates the objectivity of the declaration information in which the user whose contribution degree is to be estimated is the implementing party among the declaration information acquired by the declaration information acquisition unit 11. The objectivity of the report information indicates the degree of objectivity of the report related to the report information. That is, the degree of objectivity is the degree to which the declaration related to the declaration information is genuine (the degree of authenticity). The higher the degree of objectivity, the higher the activity indicated by the report information has been performed by the party involved in the activity indicated by the report information.

  As described above, for example, assuming that a point is given to the activity of the user, a false declaration may be made to obtain the point even though the activity is not actually performed. The objectivity in the present embodiment is for properly handling a correct declaration.

  The objectivity calculation unit 12 is configured to determine, among the declaration information acquired by the declaration information acquisition unit 11, an activity in which the user whose contribution degree is to be estimated is the implementing party and whose activity is different from the activity related to the declaration information whose objective degree is to be calculated. Based on at least one of the report information and the user other than the user whose contribution degree is to be estimated is the reporter, and at least one of the report information about activities different from the activity related to the report information for which the objective degree is calculated. Is calculated. The calculation of the objectivity is performed, for example, based on report information on activities in the past that are earlier than the activity on the report information for which the objectivity is to be calculated. In the case where the execution time information is not included in the declaration information, the objectivity is calculated based on the declaration information on all activities other than the activity related to the declaration information for which the objectivity is to be calculated. You may.

  Further, the calculation of the objectivity is performed by the user whose contribution is to be estimated, that is, the reporting information in which the active party is the reporter, and the user other than the user whose contribution is to be estimated, that is, the user who is not the active party. Is calculated by a different calculation method from that of the reporting information that is the filer. With respect to the declaration information in which the actor is the filer, for example, a certain number or more of the actors declare the activity of the actor in the past (corresponding to X described later), and The declared other party is not biased toward a specific person (corresponding to Y described later), and the number of times that the implementing party has declared its own activity in the past is the number of times that the other party has declared the performing party's activity in the past. If it is not large (corresponding to Z described later), the objectivity of the activity of the implementing party is considered to be high, and the objectivity of the report is considered to be high. FIG. 6 shows an example of a reporting relationship between users. From the above criterion, for example, the report of the user C's own activity is highly objective.

  Further, with respect to the declaration information in which another person is the filer, for example, the other person declares a certain number or more of past activities in the past (corresponding to X ′ described later), and Is not biased toward a specific person including the implementing party (corresponding to Y ′, Z ′ described later), the objectivity of the declaration of the other person is considered to be high. Based on the above criterion, for example, a report on the activity of the user C from the user A in FIG. 6 has low objectivity.

  Hereinafter, a specific calculation method of the objectivity will be described. The objectivity calculation unit 12 reads out the declaration information acquired by the declaration information acquisition unit 11. As described above, the objectivity calculation unit 12 uses report information on an activity that is different from the activity related to the report information for which the objectivity is to be calculated, in calculating the objectivity. That is, the objectivity calculation unit 12 uses the report information of the activity identifier different from the activity identifier of the report information for which the objectivity is to be calculated for the calculation of the objectivity.

  The objectivity calculation unit 12 determines that the user whose contribution is to be estimated is the reporter, and the user whose contribution is to be estimated is the implementing party, and the objectivity calculation target 12 Among the declaration information on activities different from such activities, at least one of the declaration information in which a user other than the user whose contribution is estimated is the declarant and the declaration information in which the user whose contribution is estimated is the declarant. Calculate the objectivity based on this. Based on the above-mentioned report information, the objectivity calculation unit 12 calculates the number of others who have declared the activity of the user whose contribution is to be estimated, and the number of times the other has declared the activity of the user whose contribution is to be estimated. The ratio of the number of others who have declared the activity of the user whose contribution is to be estimated, and the activity of the user whose contribution is to be estimated relative to the number of times the user himself / herself has declared the activity of the user whose contribution is being estimated. Calculates at least one of the ratios of the number of declarations, and calculates the objectivity of the declaration information in which the user whose contribution degree is to be estimated is the declarant from the calculated value. The above numbers are unique. For example, if there is a report of B (reporter) → A (activity identifier: A-101) and a report of B → A (activity identifier: A-102), the number of times that another person has declared A's activity Is twice, but the number of others who declare A's activity is one. The same applies to the number of people to be described later.

上記の式中のｍｉｎ（）は、最も小さい値を関数値とする関数である。上記の式中のｐ，ｑ，ｒは、予め設定されるパラメータである。ｐは、過去に少なくともｐ人以上の他者から活動を申告されていれば、その人物の活動（即ち、申告）には客観性があると定義するパラメータであり、０より大きい（＞０）値とされる。なお、実施当事者自身による活動の申告の客観性は、当該実施当事者による活動の客観性と等しい。ｑには、過去に実施当事者の活動を申告した他者が特定の人物に偏ることを全く許容しない場合には１が設定され、特定の人物に一定の割合で偏ることを許容する場合には０を除く１未満の正の値が設定される。ｒには、過去に実施当事者が自分自身の活動を申告した回数が、過去に他者が実施当事者の活動を申告した回数と比べ多くなることを全く許容しない場合には１が設定され、多くなることを一定の割合で許容する場合には０を除く１未満の正の値が設定される。Ｙ，Ｚの算出の際に式中の分数の分母が０になる場合（０除算時）には、それらのパラメータ（Ｙ，Ｚ）の値を１とすることとしてもよい。 Specifically, the objectivity calculation unit 12 calculates the following values X, Y, and Z as values relating to the objectivity.

Min () in the above equation is a function whose smallest value is a function value. P, q, and r in the above equation are parameters set in advance. p is a parameter that defines that if at least p or more persons have declared activities in the past, the activity (ie, declaration) of the person is objective and greater than 0 (> 0) Value. Note that the objectivity of the reporting of the activity by the implementing party itself is equal to the objectivity of the activity by the implementing party. q is set to 1 when the other party who has declared the activity of the executing party in the past is not allowed to be biased toward a specific person at all. A positive value less than 1 excluding 0 is set. r is set to 1 if the implementing party does not allow the number of times that the executing party has declared its own activity in the past to be much greater than the number of times that the other party has declared the performing party's activity in the past. If it is allowed to be a certain ratio, a positive value less than 1 except 0 is set. When the denominator of the fraction in the formula becomes 0 (when dividing by 0) in the calculation of Y and Z, the values of these parameters (Y, Z) may be set to 1.

  The objectivity calculation unit 12 calculates X × Y × Z and sets the calculated value as the objectivity for the report information. The value calculated in this way indicates that the larger the value, the greater the objectivity. FIG. 7 shows an example of the objectivity calculated as described above for the report information for the user A to report his / her own activity. In this example, (p, q, r) = (5, 1, 1).

  In the above-described formulas of X, Y, and Z, in order to make the influence of each value uniform, when the value exceeds 1, it is set to 1. However, even when the value exceeds 1, the value is set to X. , Y, and Z may be used. Further, instead of the product of X, Y, and Z as described above, the sum of X, Y, and Z may be used as the objectivity. In addition, when taking the sum, a predetermined weighting of each value may be performed. Also, it is not necessary to use all the values of X, Y, and Z, and at least one of them may be used to calculate the objectivity. Further, a value calculated by a formula other than the above formula, which meets the viewpoint of the above objectivity, may be used.

  The objectivity calculation unit 12 calculates the objectivity of the user other than the user whose contribution is to be estimated for the report information in which the user other than the user whose contribution is to be estimated is the reporter, and calculates the objectivity. The objectivity is calculated based on the report information in which a user other than the user of the filer is the executing party among the report information on activities different from the activity related to the target report information. The objectivity calculation unit 12 performs, based on the above-mentioned report information, the number of the other persons who have declared the activity by the reporter user, and the number of times that the reporter user declared the activity of the other person. Ratio of the number of others who have declared their activities by the user who is the reporter, and the user who is the reporter is other than the user whose contribution degree is to be estimated for the number of times that the reporter user has declared the activity of the other person. By calculating at least one of the ratios of the number of times that the other person's activity has been declared, the objectivity of the report information in which a user other than the user whose contribution degree is to be estimated is the reporter is calculated. That is, the objectivity of the report of B (filer) → A (performing party) is calculated from the report of B → C (other than B). That is, by referring to the declaration information indicating that B has declared the activity of another person, the value (value X ′, Y ′, Z ′ described later) related to the objectivity is calculated. The other person in the above corresponds to the above C. That is, C is a user (other than B) other than the user (B: reporter) who is the reporter other than the user whose contribution degree is to be estimated. Therefore, the others include the user whose contribution degree is to be estimated (A: the implementing party).

上記の式中のｐ´，ｑ´，ｒ´は、予め設定されるパラメータである。ｐ´は、ある人物が過去に少なくともｐ´人以上の他者の活動を申告していれば、その人物の申告には客観性があると定義するパラメータであり、０より大きい（＞０）値とされる。ｑ´には、客観度の算出対象の申告情報に係る申告者が過去に活動を申告した他者（申告者によって活動を申告された他者）が、特定の人物に偏ることを全く許容しない場合には１が設定され、特定の人物に一定の割合で偏ることを許容する場合には０を除く１未満の正の値が設定される。ｒ´には、客観度の算出対象の申告情報に係る申告者が過去に活動を申告した他者（申告者によって活動を申告された他者）が、客観度の算出対象の申告情報に係る実施当事者に偏ることを全く許容しない場合には１が設定され、実施当事者に一定の割合で偏ることを許容する場合には０を除く１未満の正の値が設定される。Ｙ´，Ｚ´の算出の際に式中の分数の分母が０になる場合（０除算時）には、それらのパラメータ（Ｙ´，Ｚ´）の値を１とすることとしてもよい。 Specifically, the objectivity calculation unit 12 calculates the following values X ′, Y ′, and Z ′ as values related to the objectivity.

P ′, q ′, and r ′ in the above equation are preset parameters. p ′ is a parameter that defines that if a certain person has declared at least p ′ or more other people's activities in the past, that person's declaration has objectivity and is greater than 0 (> 0). Value. In q ′, no other person (others whose activities have been declared by the filer) whose reporter related to the report information whose objectivity is to be calculated in the past declares activities is not allowed to be biased toward a specific person at all. In this case, 1 is set, and when it is allowed to be biased to a specific person at a fixed rate, a positive value less than 1 excluding 0 is set. In r ′, the other party (another whose activity has been declared by the filer) whose reporter related to the report information whose objectivity is to be calculated in the past is related to the report information whose objectivity is to be calculated. If the bias is not allowed at all by the implementing party, 1 is set. If the implementing party is allowed to be biased at a fixed rate, a positive value less than 1 except 0 is set. When the denominator of the fraction in the formula becomes 0 (when dividing by 0) when calculating Y ′ and Z ′, the values of these parameters (Y ′, Z ′) may be set to 1.

  The objectivity calculation unit 12 calculates X ′ × Y ′ × Z ′, and sets the calculated value as the objectivity of the report information. The value calculated in this way indicates that the larger the value, the greater the objectivity. FIG. 8 shows an example of the objectivity calculated as described above for the report information in which the user A reports the activity of the user B. In this example, (p ', q', r ') = (5, 1, 1).

  In the above formulas of X ', Y', and Z ', in order to make the influence of each value uniform, when the value exceeds 1, it is set to 1. The values may be used as the values of X ', Y', Z '. Further, instead of the product of X ', Y', Z 'as described above, the sum of X', Y ', Z' may be used as the objectivity. In addition, when taking the sum, a predetermined weighting of each value may be performed. Further, it is not necessary to use all the values of X ′, Y ′, Z ′, and at least one of them may be used to calculate the objectivity. Further, a value calculated by a formula other than the above formula, which meets the viewpoint of the above objectivity, may be used.

  The objectivity calculation unit 12 calculates, for example, the objectivity for all the report information. When the contribution calculation target is a specific user or the like, the objectivity calculation unit 12 may calculate the objectivity only for the report information in which the specific user is the implementing party. The objectivity calculated by the objectivity calculator 12 is stored in the contribution estimating device 10 in association with the declaration information as shown in the table of FIG. 2 and used by the contribution estimator 13.

  The contribution degree estimating unit 13 is a functional unit that estimates the contribution degree of the user based on the objectivity calculated by the objectivity calculation unit 12 with respect to the declaration information for which the user whose contribution degree is to be estimated is the implementing party. is there. The contribution estimation unit 13 may estimate the contribution of the user whose contribution is to be estimated based on the activity indicated in the report information. The contribution estimating unit 13 estimates the contribution of the user as follows.

  The contribution estimating unit 13 reads out the objectivity for each piece of report information calculated by the objectivity calculating unit 12. The contribution estimating unit 13 calculates an objectivity for each activity identifier (that is, a combination of the implementing party and the activity) from the read objectivity for each piece of report information. For example, the contribution degree estimating unit 13 calculates one objectivity by aggregating the objectivity of the report information of the same activity identifier (different filer) with a predetermined calculation rule set in advance. Specifically, the contribution degree estimating unit 13 calculates a sum or an average of those objectivities as an objectivity for each activity identifier. The calculated objectivity for each activity identifier is, for example, information shown in FIG.

  The contribution degree estimating unit 13 calculates the objectivity for each user (executor) from the objectivity for each activity identifier. The contribution degree estimating unit 13 calculates, for example, the objectivity for each user from the objectivity for each activity identifier using a predetermined conversion rule set in advance. Specifically, the contribution degree estimating unit 13 stores information in which activity types and values are associated with each other as shown in FIG. 10 in advance. This value is a reference value of the degree of contribution for each activity type. The higher the value, the higher the contribution. The contribution degree estimating unit 13 multiplies, for each user, the objectivity corresponding to the activity identifier by the value of the activity type corresponding to the activity identifier, and calculates a total value thereof. And The larger the calculated contribution degree, the larger the contribution. The calculated contribution degree is associated with a user (for example, a user identifier) as shown in FIG. Note that the contribution degree may be calculated for each activity (activity identifier) instead of performing the activity (activity identifier) for each user as described above. Further, the contribution degree may be calculated for each declaration (declaration information). Alternatively, the objectivity may be used as the contribution without using the reference value of the contribution for each activity type.

  The calculation of the objectivity by the objectivity calculating unit 12 and the estimation of the contribution by the contribution estimating unit 13 may be performed at a timing set in the contribution estimating device 10 in advance, or may be performed by the contribution estimating device 10. The operation of the manager on the contribution degree estimation device 10 or the like may be performed as a trigger.

  The contribution estimating unit 13 outputs the calculated contribution for each user to a module or a device that gives points to the user. The output of the contribution degree may be performed by other methods. The calculated contribution may be used not only for incentives such as giving points to the user but also for giving a penalty to the user. For example, a user whose contribution degree lower than a certain criterion, that is, an objectivity lower than a certain criterion is repeatedly calculated is regarded as a fraudulent user, and a penalty is given to the user instead of an incentive. You may.

  The calculation of the contribution by the contribution estimation unit 13 may be performed as follows in addition to the above method. The contribution estimating unit 13 may extract a feature for estimating the contribution from the activity type and the objectivity related to the activity of the user, and calculate the contribution using the feature. As the feature amount, for example, the number of activities of the user (the number of activity identifiers related to the user) or the number of activity types can be used. The greater the number of activities or the greater the number of activities, the greater the contribution of the user. For example, these values may be used as parameters to be multiplied by the contribution calculated as described above to obtain the final contribution. Alternatively, the contribution may be estimated by multiplying not the contribution but the objectivity calculated as described above. Further, as the multiplied objectivity, an average objectivity that can be extracted from the objectivity for each activity identifier of the user may be used. The greater the average objectivity, the greater the contribution of the user. In this case, a value obtained by multiplying all of them may be used as the contribution. For example, if the number of activities is four, the number of activity types is three, and the average objectivity is 0.5 (50%), 4 × 3 × 0.5 = 6 may be used as the contribution. Note that the parameters to be multiplied may be standardized according to the contribution calculation method so that the value of the finally calculated contribution becomes an appropriate value. For example, the value of the parameter may be divided by the maximum value or the like so as to be adjusted to a value of 0 to 1 (the same applies to the following parameters).

  Further, the contribution estimating unit 13 may estimate the contribution of the user whose contribution is to be estimated based on the contribution of users other than the user whose contribution is to be estimated. As a result, in addition to the information of the filer's past declarations made by others, the filer's own activities performed in the past and the objectivity to the activities are also calculated by the contributions made by the filer made by others. Affect. For example, a declaration from a user with a high contribution can be regarded as a declaration with higher objectiveness. Specifically, the contribution degree estimating unit 13 calculates the degree of contribution by multiplying the objectivity of each of the declaration information by the contribution degree of the filer related to the declaration information as a parameter, and multiplying the multiplied value in the same manner as described above. May be used. For a user whose contribution has not been calculated, a preset default value may be used instead of the contribution.

  In addition, the contribution estimation unit 13 determines the contribution estimation target based on the declaration information in which the user whose contribution is to be estimated is the filer and the user other than the user whose contribution is being estimated is the implementing party. The user's contribution may be estimated. Not only the user's activities, but also the user's declaration of the activities of others can be considered as one contributing activity. Therefore, the contribution of the user may be estimated in consideration of the declaration of the activity of the other user of the user whose contribution is to be estimated as described above. Further, the contribution degree of the user whose contribution degree is to be estimated may be estimated based on the objectivity of the report information. Specifically, the contribution degree estimating unit 13 can extract the above-mentioned declaration information and use the number of the declaration information (the number of declarations), the average objectivity, and the like as parameters. The contribution estimation unit 13 may multiply these parameters by a preset coefficient, add the multiplied value to the contribution calculated as described above, and determine the final contribution. Alternatively, these parameters may be multiplied by the contribution calculated as described above to obtain the final contribution. Alternatively, conversion such as one report = 5 points may be performed, and points adjusted by the objectivity of the report information may be added to the contribution degree. For example, among the declarations made by the user whose contribution degree is to be estimated, there are declaration information with an objectivity of 0.5 (50%) and declaration information with an objectivity of 0.7 (70%) (two times in total). It is conceivable to add 5 × 0.5 + 5 × 0.7 = 6.0 to the contribution. The above is the function of the contribution degree estimation device 10 according to the present embodiment.

  Subsequently, the processing executed by the contribution estimation device 10 according to the present embodiment (the operation method performed by the contribution estimation device 10) will be described with reference to the flowchart of FIG. In this process, the declaration information acquisition unit 11 acquires the declaration information (S01). Subsequently, the objectivity calculation unit 12 calculates the objectivity of the reporting information in which the user whose contribution is to be estimated is the implementing party (S02). The calculation of objectivity is performed by a user other than the user whose contribution degree is to be estimated, the user who is the executing party, and which is an activity different from the activity related to the report information to be calculated of objectivity, and the user whose contribution degree is to be estimated. Are reporters, and are performed based on at least one of report information on activities different from the activity related to the report information for which the objectivity is to be calculated. Subsequently, the contribution degree of the user is estimated and output by the contribution degree estimation unit 13 based on the objectivity (S03). The above is the processing executed by the contribution estimation device 10 according to the present embodiment.

  As described above, in the present embodiment, the contribution degree of a user whose contribution degree is to be estimated is estimated based on the declaration information in which the user is the implementing party. At this time, the objectivity of the report information used for estimating the contribution is calculated, and the objectivity is considered when estimating the contribution. This makes it possible to quantitatively determine how objectively the user's activity is performed. For example, if a user's activity is declared by highly objective reporting information, it can be considered that the user's activity is highly likely to have been performed. On the other hand, if the activity of the user is declared by the declaration information with low objectivity, it can be considered that there is a high possibility that the activity of the user is not actually performed. Therefore, according to the present embodiment, it is possible to objectively evaluate a user's activity and estimate a highly accurate contribution of the user to a predetermined group or organization.

  In addition, by setting an incentive or a penalty according to the degree of contribution as described above, the user performs a contribution activity that can obtain a high degree of objectivity in order to gain or not to lose. As described above, the user has a motivation to increase the contribution degree, and it is possible to suppress the report of the illegal behavior. As a result, a more accurate contribution degree estimation becomes possible.

  Further, as in the present embodiment, both the declaration information in which the user whose contribution degree is to be estimated is the declarant and the declaration information in which the user other than the user whose contribution degree is to be estimated is the declarant. Objectivity may be calculated and both of them may be used for estimating the contribution. Further, only one of the respective pieces of report information may be used for estimating the contribution degree. According to this configuration, the contribution degree can be appropriately and reliably estimated.

  Also, as in the present embodiment, the values of X to Z and X 'to Z' may be calculated based on the declaration information to calculate the objectivity. According to this configuration, it is possible to appropriately and reliably calculate the objectivity. However, the method of calculating the objectivity is not limited to the above, and any method may be used as long as it is calculated using the above-described report information.

  Further, as described above, the contribution may be estimated based on information indicating an activity such as an activity type. According to this configuration, when many types of activities are assumed, the contribution can be calculated by appropriately evaluating the activities. However, when only one type of activity is assumed, it is not always necessary to use information indicating the activity.

  Further, as described above, in calculating the contribution, the contribution of a user other than the user whose contribution is to be estimated, or the user whose contribution is to be estimated is the filer, and the user other than the user whose contribution is to be estimated. May be used as the execution party. By using these, it is possible to calculate more appropriate contributions from various viewpoints. However, it is not always necessary to use such information for calculating the degree of contribution.

  In the above-described embodiment, the declaration of the activity is performed after the executing party is specified. However, when a person other than the implementing party makes a declaration, it may be difficult to identify the implementing party. For example, there is a case where another person confirms that trash is being discarded, but does not know who dumped the trash. In such a case, the contribution estimation device 10 may specify the implementing party as described below and acquire information indicating the implementing party of the report information.

  The declaration information acquisition unit 11 acquires position information indicating the position of the user, acquires execution position information indicating the position where the implementing party has performed an activity, and based on the acquired position information and the execution position information, identifies the implementing party. Identify and acquire information indicating the party implementing the declaration information. Specifically, the declaration information obtaining unit 11 obtains information indicating the implementing party as follows.

  The declaration information acquisition unit 11 acquires position information indicating the position of the user and time information indicating the time at which the user was at the position for each user. As the position information, for example, latitude and longitude acquired by a GPS function provided in a portable terminal (may be the same as the external device 20) such as a mobile communication terminal carried by the user, or a portable terminal Information indicating the base station of the communication carrier that is located is used. The reporting information acquisition unit 11 acquires periodic position information and time information (for example, information every minute). FIG. 13 shows an example of the acquired position information and time information.

  In addition, the declaration information acquisition unit 11 acquires declaration information that does not include information indicating an executing party but includes execution time information and execution position information. The declaration information acquisition unit 11 compares the execution time information and the execution position information included in the declaration information with the position information and the time information of each user. The reporting information acquisition unit 11 extracts the user who stayed at the time and place indicated by the implementation time information and the implementation location information by this comparison, and identifies the user as the implementing party related to the reporting information. Since the filer has not confirmed the activity of the implementing party, the time indicated in the implementation time information may not be accurate. Therefore, for example, if the time indicated in the user's time information is included in a time range that is set back to a certain time in the past from the time indicated in the execution time information, the user stays at the time indicated by the execution position information. It may be what you did. In addition, in consideration of the time and position errors, if the time and position indicated in the user's time information and position information are included in a certain range of time and position based on the execution time information and the execution position information, The user may be staying at the time and position indicated by the execution time information and the execution position information.

  By specifying the implementing party as described above, the reporting information can be obtained and the contribution of the user can be estimated even if the submitter has not been able to recognize the implementing party.
