[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] First Embodiment

[0015] FIG. 1 shows the configuration of a questionnaire system according to one embodiment of the present invention.

[0016] As shown in the diagram, the questionnaire system is configured by connecting a server device 1, a questioner's terminal device 2, and a respondent's terminal device 3 to a communication network such as the Internet wirelessly or via a wired connection. The terminal devices 2 and 3 can be various devices such as smartphones, tablet devices, notebook personal computers, and desktop personal computers.

[0017] In this configuration, the terminal devices 2 and 3 are able to post, view, and answer questions on a timeline by implementing an application program provided by the server device 1. More specifically, when a question is sent from the questioner's terminal device 2, the server device 1 processes the question, selects suitable answerers for the question, and recruits the selected answerers to answer the question. The server device 1 then posts the question to answerers who have agreed, accepts their answers, and tally them up. The server device 1 generates display data based on the tallying results and presents the answers on a timeline.

[0018] FIG. 2 shows the configuration of the server device of the questionnaire system, which will now be described.

[0019] As shown in the figure, the server device 1 has a control unit 11, a communication interface (I / F) 12, and a storage unit 13. The control unit 11, the communication I / F 12, and the storage unit 13 are communicably connected via a system bus. In addition to these components, the server device 1 may have input units such as a keyboard and a mouse, and a display unit such as a liquid crystal display for displaying various information.

[0020] The communication I / F 12 is realized by, for example, a network interface card (NIC), and is connected to a communication network 4 such as the Internet via a wired or wireless connection, and is a communication interface for communicating with the terminal device 32. The storage unit 13 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, a hard disk drive (HDD), or an optical disk device, and stores in advance the programs to be executed by the control unit 11. The storage unit 13 also has a user information storage unit 14, a questionnaire information storage unit 15, a respondent selection storage unit 16, a payment information storage unit 17, etc.

[0021] The user information storage unit 14 stores, linked to the user ID, basic registration information such as the user's gender, age, place of residence, nearest station, educational background, occupation, average smartphone usage time, hobbies, preferences, and interests, as well as answer history information, posting history information, browsing history information, high rating (like) information, browsing history of SNS provided by the server device 1, and payment information. For ease of explanation, in Fig. 1, the questioner's terminal device 2 and the answerer's terminal device 3 are shown separately, but a user can be both a questioner and an answerer.

[0022] The survey information storage unit 15 stores, in association with the question ID, the question category, the user ID of the questioner, the question content, the posting date and time, the user ID of the selected answer candidate, the user ID of the answerer who actually answered, the answer content, the answer date and time, high rating (like) information, and the payment ID.

[0023] The answerer selection storage unit 16 stores feature quantities calculated in advance by the learning unit 11e using all columns linked to the user IDs of answerers, feature quantities calculated in advance by the learning unit 11e using columns linked to the user IDs of answerers who provided accepted answers, and scoring results (ranking and evaluation) for each category of each user calculated by the learning unit 11e using the feature quantities, which are referenced when the answerer selection unit 11d-2 selects an answerer suitable for a question category. Furthermore, the answerer selection storage unit 16 stores a table for calculating the variance of answerers by category of question at each division of basic registration information, setting a threshold value, and evaluating whether they are suitable for the category based on their relationship with the threshold value (below the threshold value, above the threshold value, etc.) using a statistical method.

[0024] The payment information storage unit 17 stores, in association with a payment ID, a question ID, payment information of the questioner, payment information of the answerer, payment status information, etc. The payment information of the questioner includes payment information associated with the question, and the payment information of the answerer includes consideration information associated with the answer.

[0025] The control unit 11 is realized by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. The control unit 11 may be configured by an integrated circuit such as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Array), or the like. By executing a program stored in the storage unit 13, the control unit 11 functions as a main control unit 11a, a transmission unit 11b, a reception unit 11c, a survey execution unit 11d, a learning unit 11e, a settlement unit 11f, a generation unit 11g, and the like. The survey execution unit 11d further functions as a question processing unit 11d-1, a respondent selection unit 11d-2, a collection unit 11d-3, a question posting unit 11d-4, a response processing unit 11d-5, and a counting unit 11d-6.

[0026] In this configuration, the transmitting unit 11b transmits various display data and the like to the terminal devices 2 and 3. The receiving unit 11c receives various information transmitted from the terminal devices 2 and 3, such as the user's basic registration information, question information, and answer information.

[0027] The survey execution unit 11d executes the survey. More specifically, the question processing unit 11d-1 receives and processes question information transmitted from the terminal device 2 of the questioner and received by the receiving unit 11c, registers the question information in the user information storage unit 14 in association with the user ID of the questioner, and registers the question information in the survey information storage unit 15 in association with the issued question ID.

[0028] The answerer selection unit 11d-2 selects the most suitable answerer based on the category related to the question information. Specifically, the answerer selection unit 11d-2 refers to the answerer selection storage unit 16 and selects an answerer based on the feature values ​​calculated in advance by the learning unit 11e using all columns linked to the answerer's user ID, the feature values ​​calculated in advance by the learning unit 11e using columns linked to the user ID of the answerer who provided the adopted answer, and the scoring results (ranking and evaluation) for each category of each user calculated by the learning unit 11e using the feature values. Alternatively, the answerer selection storage unit 16 may select an appropriate answerer by comparing the variance of each item of basic registration information data for each question category with a predetermined threshold (below the threshold, above the threshold, etc.).

[0029] The solicitation unit 11d-3 solicits respondents from the candidate respondents selected by the answerer selection unit 11d-2. The question posting unit 11d-4 posts questions on a timeline for respondents who have agreed to be answers in response to the solicitation. The answer processing unit 11d-5 receives and processes answer information from respondents, registers the answer information in the questionnaire information storage unit 15, and also registers the answer information as an answer history in the user information storage unit 14. The counting unit 11d-6 counts the received answer information. Specifically, for each answer option, the number of respondents who selected each option and their percentage of the total are calculated.

[0030] The learning unit 11e periodically refers to the user information storage unit 14 and the questionnaire information storage unit 15, calculates feature amounts using all columns linked to the user IDs of respondents, calculates feature amounts using columns linked to the user IDs of respondents who provided adopted answers, performs scoring (ranking and evaluation) for each category of each user using these feature amounts, and updates the scoring results registered in the answerer selection storage unit 16. Furthermore, the learning unit 11e calculates the variance of answerers by question category at the division of each item data of the basic registration information, and then updates a table for selecting suitable answerers by comparing them with a predetermined threshold (below the threshold, above the threshold, etc.), and registers the updated table in the answerer selection storage unit 16.

[0031] The settlement unit 11f executes electronic settlement, such as making a payment according to the level of the question from the questioner and a payment according to the level of the answer to the answerer. At this time, the settlement information stored in the user information storage unit 14 is referenced, and the content and status of the settlement are registered in the settlement information storage unit 17. The generation unit 11g visualizes the results tallied by the aggregation unit 11d-6 and generates display data. The SNS execution unit 11h realizes interactions between users on a timeline, etc. In addition, the main control unit 11a is responsible for overall control, such as user authentication.

[0032] FIG. 3 shows the configuration of the terminal device of the questionnaire system, which will now be described.

[0033] As shown in the figure, the terminal device 2 has a control unit 21, a communication I / F 22, an operation input unit 23, a display unit 24, a location information acquisition unit 25, and a storage unit 26. The units 21 to 26 are connected to each other so as to be able to communicate with each other via a system bus. The communication I / F 22 is realized by, for example, an NIC or the like, and is a communication interface that is connected to a communication network 3 such as the Internet by wire or wirelessly and communicates with the server device 1 or the like.

[0034] The operation input unit 23 is realized by a mouse, keyboard, etc., and accepts various operation inputs from the user. The display unit 24 is realized by a liquid crystal display, etc., and displays various screens. The operation input unit 23 and the display unit 24 may be integrated into one unit as a touch panel. The storage unit 25 is realized by a semiconductor memory element such as RAM or flash memory, a HDD, or an optical disk device, for example, and stores programs executed by the control unit 21.

[0035] The control unit 21 is realized by a CPU, an MPU, etc., and may be configured by an integrated circuit such as an ASIC, an FPGA, etc. The control unit 21 reads and executes programs stored in the storage unit 25, thereby functioning as a main control unit 21a, a transmission unit 21b, a reception unit 21c, and a display control unit 21d.

[0036] In this configuration, the transmitting unit 21b transmits the user's basic registration information, questions, various answer requests, question information, answer information, etc. to the server device 1. The receiving unit 21c receives display data, etc. from the server device 1. Then, the display control unit 21d displays various screens on the display unit 24 based on the display data. In addition, the main control unit 21a controls the entire terminal device.

[0037] The processing flow of the questionnaire system according to the embodiment of the present invention will be described in detail below with reference to the flowchart in Fig. 4. Here, screen display examples in Fig. 5(a) to Fig. 5(d) will be referred to as appropriate.

[0038] As shown in FIG. 5(a), various questions and answers are displayed on a timeline on the questioner's terminal device 2. On the screen 100, reference numeral 100a denotes a button for displaying newest questions, reference numeral 100b denotes a button for displaying recommended questions, reference numeral 100c denotes a button for displaying top search results, and reference numeral 100d denotes a button for displaying answers by most respondents. The display mode can be changed by selecting any of these buttons. Reference numeral 100e denotes a button for displaying paid question details, and reference numeral 100f denotes a button for selecting whether to display or hide options. Reference numeral 100g denotes a button for displaying only the question, reference numeral 100h denotes a button for displaying questions and options, reference numeral 100i denotes a button for displaying questions and answer results, and reference numeral 100j denotes a button for creating a question. When the questioner selects the create question button 100j, the screen switches to the screen 101 shown in FIG. 5(b). After selecting either the single question button 101a or the multiple questions button 101b, the questioner enters the question in text. When a question is input by operating the operation input unit 23, the transmission unit 21b transmits the question information to the server device 1 via the communication I / F 22 under the control of the main control unit 21a (S1).

[0039] In the server device 1, the receiving unit 11c receives the question information from the terminal device 2 (S2), and the question processing unit 11d-1 accepts and processes the question information sent from the questioner's terminal device 2 and received by the receiving unit 11c, registers the question information in the user information storage unit 14 in association with the questioner's user ID, and registers the question information in the survey information storage unit 15 in association with the issued question ID (S3).

[0040] The answerer selection unit 11d-2 selects the most suitable answerer based on the category related to the question information. Specifically, the answerer selection unit 11d-2 refers to the answerer selection storage unit 16 and selects the answerer based on the feature values ​​calculated in advance by the learning unit 11e using all columns linked to the answerer's user ID, the feature values ​​calculated in advance by the learning unit 11e using columns linked to the user ID of the answerer who provided the adopted answer, and the scoring results (ranking and evaluation) for each category of each user calculated by the learning unit 11e using the feature values. Alternatively, the answerer selection storage unit 16 may select the most suitable answerer by comparing the variance of each item data of the basic registration information for each question category with a predetermined threshold (below the threshold, above the threshold, etc.) (S4).

[0041] The soliciting unit 11d-3 solicits respondents from the candidate answerers selected by the answerer selecting unit 11d-2 (S5). The question posting unit 11d-4 posts a question on the timeline for answerers who have agreed to be answerers in response to the solicitation (S6). In the answerer's terminal device 3, the receiving unit 21c receives display data related to the question, and under the control of the display control unit 21d, displays the question on the timeline on the display unit 24 (S7). When an answer is input by operating the operation input unit 23, under the control of the main control unit 21a, the transmitting unit 21b transmits the answer information to the server device 1 (S8).

[0042] The response processing unit 11d-5 receives and processes the response information from the respondent, and registers the response information in the questionnaire information storage unit 15 and also registers it as a response history in the user information storage unit 14 (S9). Subsequently, the counting unit 11d-6 counts the received and processed response information. More specifically, for example, for each answer option, the number of respondents who selected each option and the percentage of respondents who selected each option relative to the total are calculated (S10).

[0043] The generation unit 11g visualizes the results tallied by the tallying unit 11d-6 and generates display data (S11). The transmission unit 11b transmits this display data to the questioner's terminal device 2 (S12). In the questioner's terminal device 2, the reception unit 21c receives the display data (S13) and, under the control of the display control unit 21d, displays the tallied results and the like on the display unit 24 (S14). This completes the series of processes.

[0044] An example of the display on the terminal device 2 is as shown in Figure 5(c), and on the screen 102, the display mode can be changed using the graph display button 102a, the comment posting / viewing button 102b, and the percentage display / vote display switching button 102c, and it is also possible to switch to displaying the answers of respondents related to attributes such as the respondent's gender, age, place of residence, educational background, occupation, annual income, and smartphone usage time using the result display by attribute button 101d, or to switch to displaying the results by option using the result display by option button 102e.

[0045] Furthermore, the SNS function provided by the server device 1 makes it possible to check SNS comments on the screen 103, etc. On the screen 103, reference numeral 103a denotes a newest display button, reference numeral 103b denotes a posted order display button, reference numeral 103c denotes a recommended order display button, and by selecting a comment posting button 103d, the screen changes to a comment input screen, where a comment can be posted.

[0046] The survey system according to the first embodiment of the present invention described above allows users to post, view, and repost questions on a timeline. Furthermore, it is possible to select the most suitable respondent for each question category, solicit responses, and post the question to those who agree, thereby enabling a survey that meets the needs of the questioner.

[0047] Second Embodiment

[0048] The configurations of the questionnaire system, server device, and terminal device in the second embodiment of the present invention are the same as those shown in Figures 1, 2(a), 2(b), and 3, so the following explanation will be given with appropriate reference to Figures 1, 2(a), 2(b), and 3.

[0049] The questionnaire system of this embodiment selects pre-selected users who have booked responses from the event venue, etc., immediately after the event, etc., and identifies them as respondents by assuming that they are event participants based on their location information. The system then posts questions to these respondents, thereby obtaining highly accurate responses such as their impressions of the event, etc.

[0050] First, an outline of the processing performed by the questionnaire system according to the second embodiment of the present invention will be described with reference to the conceptual diagram of FIG.

[0051] As shown in the figure, the server device 1 operates a survey service site (#1). The server device 1 invites users who are likely to answer the survey to make reservations to answer the survey via the service site (#2). The users send survey response reservations to the server device 1 from their terminal devices 2 (#3). The server device 1 accepts these response reservations and grants reward rights after answering the survey to the terminal devices 2 of the answer-reserving users (#4). After the event is held, the server device 1 posts questions to the answer-reserving users and receives their answers (#5). The server device 1 tallys these answers (#6) and provides the results to the terminal device 2 in real time (#7). The server device 1 then receives payment from the terminal devices 2 (#8) and pays rewards to the respondents for their answers (#9).

[0052] Hereinafter, the processing procedure of the questionnaire system according to the second embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

[0053] First, in the questioner's terminal device 2, the transmission unit 21b transmits a question reservation to the server device 1 (S21). When reserving a question, the terminal device 2 transmits the content of the question (for example, the date and time of the event, the venue, the category of the event, etc.). In the server device, the reception unit 11c accepts the question reservation, and the question processing unit 11d-1 processes it (S22). The answerer selection unit 11d-2 checks the content of the question and the user information stored in the user information storage unit 14 of the storage unit 13, and selects an appropriate answerer to answer the question (S23).

[0054] That is, the answerer selection unit 11d-2 selects the most suitable answerer based on the category related to the question information. More specifically, the answerer selection unit 11d-2 refers to the answerer selection storage unit 16 and selects an answerer based on the feature amounts calculated in advance by the learning unit 11e using all columns linked to the answerer's user ID, the feature amounts calculated in advance by the learning unit 11e using columns linked to the user ID of the answerer who provided the adopted answer, and the scoring results (ranking and evaluation) for each category of each user calculated by the learning unit 11e using the feature amounts. Alternatively, the answerer selection storage unit 16 may select an appropriate answerer by comparing the variance of each item data of the basic registration information for each question category with a predetermined threshold (below the threshold, above the threshold, etc.).

[0055] Next, in the server device 1, the soliciting unit 11d-3 solicits answers from the candidate answers selected by the answerer selecting unit 11d-2 (S24). In the respondent's terminal device 3, the receiving unit 21c receives the display data related to the question and, under the control of the display control unit 21d, displays the contents of the answer reservation solicitation on the display unit 24 (S25). When an instruction to reserve an answer is input by operating the operation input unit 23, the sending unit 21b sends the answer reservation to the server device 1 under the control of the main control unit 21a (S26). In the server device 1, the receiving unit 11c accepts the answer reservation and registers it in the user information storage unit 14 and the questionnaire information storage unit 15 (S27).

[0056] When the event start date and time has passed, the server device 1 determines that the event has been held (branching S28 to Yes), acquires location information of users who have reserved answers at the time the event ends from the terminal device 3, the answerer selection unit 11d-2 identifies users who are located within a predetermined range from the event location based on the location information as answerers (S29), and the question posting unit 11d-4 posts a question on the timeline for the identified answerers (S30). In the answerer's terminal device 3, the receiving unit 21c receives display data related to the question, and under the control of the display control unit 21d, displays the question on the timeline on the display unit 24 (S31), and when an answer is input by operating the operation input unit 23, the sending unit 21b sends the answer information to the server device 1 under the control of the main control unit 21a (S32).

[0057] In the server device 1, the answer processing unit 11d-5 receives and processes the answer information sent from the answerers, and registers the answer information in the questionnaire information storage unit 15 and also registers it as an answer history in the user information storage unit 14 (S33). Then, the counting unit 11d-6 counts the received answer information. More specifically, for example, for each answer option, the number of respondents who selected each option and the percentage of respondents who selected each option relative to the total are calculated (S34).

[0058] In the server device 1, the generation unit 11g visualizes the results tallied by the tallying unit 11d-6 and generates display data (S35). The transmission unit 11b transmits this display data to the questioner's terminal device 2 (S36). In the questioner's terminal device 2, the reception unit 21c receives the display data (S37) and, under the control of the display control unit 21d, displays the tallied results and the like on the display unit 24 (S38). Thereafter, in the server device 1, the settlement unit 11f receives payment from the questioner's terminal device 2, pays the answer reward to the answerer's terminal device 3 by electronic settlement, and updates the contents of the settlement information storage unit 17 (S39). This completes the series of processes.

[0059] In the above example, we have explained the posting of questions about an event with a clear date, time, and location, and the implementation of a survey related to the answers and tallying of the results, but this is not limited to this, and it is also possible to conduct a survey to coincide with the opening of a new store such as a cafe. In this case, the same processing as above is performed based on the store's location, opening date, and store category.

[0060] As described above, according to the second embodiment of the present invention, an answerer who is suitable for answering a question is ultimately identified based on the user's location information, and a survey is then conducted, thereby making it possible to obtain a highly accurate answer to the questioner's question.

[0061] <Third embodiment>

[0062] The configurations of the questionnaire system, server device, and terminal device in the third embodiment of the present invention are the same as those shown in Figures 1, 2(a), 2(b), and 3, so the following explanation will be given with appropriate reference to Figures 1, 2(a), 2(b), and 3.

[0063] The questionnaire system according to this embodiment, when a disaster such as an earthquake occurs, instantly identifies users who are within a predetermined range of the disaster area as respondents and posts questions to those respondents, thereby making it possible to grasp the situation of the earthquake, etc. Alternatively, it recruits respondents about policies, obtains responses about the policies, and provides the analysis results related to the policies to the government, local authorities, and lifeline operators.

[0064] First, an outline of the processing performed by the questionnaire system according to the second embodiment of the present invention will be described with reference to the conceptual diagram of FIG.

[0065] As shown in the figure, the server device 1 operates a survey service site (#21). The server device 1 invites users located within a predetermined range of the disaster area to fill out a survey (#22), accepts responses about the disaster area from the users (#23), tallying the responses (#24), and provides the analysis results in real time to terminal devices 2 of government, administrative bodies, and lifeline operators (#25). The server device 1 then receives payment from the terminal devices 2 (#26). The server device 1 provides information about lifelines and supplies to disaster-affected users, and provides disaster area information to holders of disaster area information (#27, #28).

[0066] A similar system can also be used for surveys about policies, where the server device 1 invites users who match the policy content to take the survey (#31), accepts responses about the policy from those users (#32), tallying the responses (#24), and provides the analysis results in real time to the terminal device 2 of the government, administration, or lifeline operator (#25).The server device 1 then receives payment from the terminal device 2 (#26).A communication activation community about the policy content is provided (#33), and the communication content is shared with the community of users who are the target of the policy (#34).

[0067] Hereinafter, the processing procedure of the questionnaire system according to the second embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

[0068] When a disaster such as an earthquake occurs, the transmission unit 21b of the questioner's terminal device 2 transmits disaster information relating to the disaster, such as the affected area (latitude, longitude, affected range, etc.) and seismic intensity, to the server device 1 (S41).

[0069] In the server device 1, the receiving unit 11c receives the disaster information from the terminal device 2 (S42), and the question processing unit 11d-1 accepts and processes the disaster information sent from the questioner's terminal device 2 and received by the receiving unit 11c, registers the disaster information in the user information storage unit 14 by linking it to the questioner's user ID, and registers the disaster information in the survey information storage unit 15 by linking it to the issued question ID (S43).

[0070] The respondent selection unit 11d-2 identifies users located within a predetermined range of the disaster area (the epicenter in the case of an assessment) based on the latitude and longitude of the disaster area included in the disaster information, based on the location information of the user's terminal device 3, and selects the most suitable respondent (S44). At this time, in addition to the location information, the respondent selection storage unit 16 may refer to the feature values ​​calculated in advance by the learning unit 11e for all columns linked to the respondent's user ID, the feature values ​​calculated in advance by the learning unit 11e for columns linked to the user ID of the respondent who provided the selected answer, and the scoring results (ranking and evaluation) for each category of each user calculated by the learning unit 11e based on the feature values. Alternatively, the respondent selection storage unit 16 may select suitable respondents by dividing the data of each item of basic registration information by question category, comparing the data with a predetermined threshold (below the threshold, above the threshold, etc.).

[0071] The question posting unit 11d-4 posts the question on the timeline to answerers who have agreed to answer the above-mentioned call (S45). In the answerer's terminal device 3, the receiving unit 21c receives the display data related to the question, and under the control of the display control unit 21d, displays the question on the timeline on the display unit 24 (S46). When an answer is input by operating the operation input unit 23, the transmitting unit 21b transmits the answer information to the server device 1 under the control of the main control unit 21a (S47).

[0072] The response processing unit 11d-5 receives and processes the response information from the respondent, and registers the response information in the questionnaire information storage unit 15 and also registers it as a response history in the user information storage unit 14 (S48). Subsequently, the counting unit 11d-6 counts the received and processed response information. More specifically, for example, for each answer option, the number of respondents who selected each option and the percentage of respondents who selected each option relative to the total are calculated (S49).

[0073] The generation unit 11g visualizes the results tallied by the tallying unit 11d-6 and generates display data (S50). The transmission unit 11b transmits this display data to the questioner's terminal device 2 (S51). In the questioner's terminal device 2, the reception unit 21c receives the display data (S52) and, under the control of the display control unit 21d, displays the tallied results and the like on the display unit 24 (S53). Thereafter, in the server device 1, the settlement unit 11f accepts and processes the payment of the consideration from the questioner's terminal device 2 by electronic settlement and updates the contents of the settlement information storage unit 17 (S54). This completes the series of processes.

[0074] As described above, according to the third embodiment of the present invention, disaster victims are identified as respondents based on user location information, and a questionnaire is then conducted, making it possible to obtain highly accurate responses regarding the disaster. Furthermore, it is also possible to provide information on lifelines, etc. to disaster victims.

[0075] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various improvements and modifications are possible without departing from the spirit of the present invention.

[0076] For example, when the respondent selection unit selects respondents, if the number of dimensions in the columns of the user's basic registration information is large, it is of course possible to utilize machine learning without teacher data to reduce the number of dimensions handled and regenerate columns divided into several groups, thereby deriving useful features.
