[Configuration of server device 30]
FIG. 3 is a schematic configuration diagram of the server device 30. As shown in FIG.

The server device 30 is a computer device such as a server computer, and is typically installed in a server on a cloud.

As shown in FIG. 3, the server device 30 includes a respondent identification DB 31 (database; the same applies hereinafter), a questionnaire management DB 32, a respondent submitted data management DB 33, a cluster table 34, an input means 35, a communication unit 36, an HDD 37, a control unit Equipped with 38 mag. The respondent identification DB 31, the questionnaire management DB 32, the respondent submitted data management DB 33, the cluster table 34, the input means 35, the communication unit 36, and the HDD 37 are connected to the control unit 38 via a bus or the like. Note that the cluster table 34 may be omitted.

Identification information (ID, password, etc.) of each respondent is registered (stored) in the respondent identification DB 31. The respondent identification DB 31 is mainly used to determine whether each respondent terminal 20 attempting to access (log in) to the server device 30 is an authorized user. Note that since the necessity of identifying respondents differs from person to person, the respondent identification DB 31 may be omitted.

In the questionnaire management DB 32, a response form for a questionnaire created in advance and a reception identifier, which is identification information of the response form, are registered (stored) in association with each other.

In the respondent submission data management DB 33, answers (response data) received from each respondent terminal 20 are accumulated (stored).

FIG. 4 is an example of the respondent submitted data management DB 33.

As shown in FIG. 4, the respondent submission data management DB 33 includes items such as "answer number", "answer", and "ID".

The answer number is stored in the "answer number" field. “Answer” stores the answer (answer data) received from the respondent terminal 20. In "ID", the ID of the respondent received from the respondent terminal 20 together with the answer is stored. Note that if the respondent identification DB 31 is not used, the ID is not stored.

The cluster table 34 stores the classification results of the answers. Clusters and response classification will be described later. The cluster table 34 is stored in a storage unit such as the HDD 37 or the RAM of the control unit 38.

FIG. 5 is an example of the cluster table 34.

As shown in FIG. 5, the cluster table 34 includes items such as cluster identification information 34a, number of answers 34b, cluster name 34c, and answers 34d.

Cluster identification information for identifying clusters is stored in the cluster identification information 34a.

The number of answers 34b stores the number of answers classified into the cluster identified by the cluster identification information 34a. Hereinafter, answers classified into clusters identified by the cluster identification information 34a may be referred to as answers belonging to the cluster.

The cluster name 34c stores the cluster name of the cluster identified by the cluster identification information 34a.

The answer 34d stores answers belonging to the cluster identified by the cluster identification information 34a.

The input means 35 is, for example, a keyboard, a mouse, or a touch panel.

The communication unit 36 communicates with each of the plurality of respondent terminals 20 via the network NW.

The HDD 37 is a hard disk device that stores an OS, a server program executed on the OS, and the like.

Although not shown, the control unit 38 includes a CPU, RAM, and ROM. As shown in FIG. 3, the control unit 38 causes the CPU to execute a predetermined program (server program) read into the RAM from the HDD 37, so that as shown in FIG. It functions as a representative answer calculation means 38d and a clustering condition setting means 38e. Note that the answer number counting means 38b and the cluster name calculating means 38c can be considered as part of the clustering execution means 38a.

Further, although not shown, the CPU executes a predetermined program (server program) read into the RAM from the HDD 37, so that each respondent terminal 20 attempting to access (log in) to the server device 30 The function of determining whether the user is an authorized user (function as an authentication server), the identification information of the answer form is transmitted to the respondent terminal 20 that requested the answer form by sending the answer form identification information (reception identifier). A function to read the associated response form from the questionnaire management DB 32 and send it, a function to receive the response sent by each respondent terminal 20 and identification information (reception identifier) of the response form, and a function to submit the received response to the respondent. It has a function of storing data in the data management DB 33.

The clustering execution means 38a executes a process (clustering) of analyzing the answers (groups) accumulated in the answerer submission data management DB 33 and classifying them into a plurality of clusters. Specifically, the clustering execution means 38a executes vectorization of each of the answers accumulated in the respondent submission data management DB 33 (vectorization of answers), calculates the distance between the answer vectors, and calculates the distance between the answer vectors. , similar meanings) are grouped together as a cluster.

Vectorization of answers or words means plotting the words into a semantic space. By vectorizing answers and words, it becomes possible to perform semantic vector operations (arithmetic operations, distance calculations) between answer sentences or between vectorized words and answer sentences.

By vectorizing the answers as described above, the degree of similarity between answers can be quantified as a distance. As a result, answers that are close to each other (that is, have similar meanings) can be grouped together as a cluster using a general clustering method (for example, K-means).

The number of clusters (eg, upper limit number) that can be grouped together by the clustering execution means 38a can be set, for example, by the clustering condition setting means 38e. For example, if nine is set as the number of clusters to be grouped together by the clustering execution means 38a, a maximum of nine clusters (cluster table 34) are generated, as shown in FIG.

The answer number counting means 38b counts the number of answers belonging to a cluster. Specifically, the answer number counting means 38b counts the number of answers stored in the answers 34d in the cluster table 34 for each cluster (cluster identification information).

The cluster name calculation means 38c calculates the cluster name of the cluster. Specifically, for example, the cluster name calculation means 38c selects the cluster name from among the words (groups) included in each answer stored in the answer 34d in the cluster table 34 for each cluster (cluster identification information). N1 (for example, N1=3) words that are close to the center of gravity (that is, have close meanings) are calculated. Note that the center of gravity of a cluster is the average value of the answer vectors of the answers stored in the answer 34d in the cluster table 34. The center of gravity of the cluster is calculated for each cluster (cluster table 34).

The cluster name (N1 words) calculated as above is the tendency of the answers (group) belonging to the cluster, that is, the tendency of all the answers (group) belonging to the cluster, for example, the tendency of all the answers (group) belonging to the cluster. ) indicates what kind of content is common, and what all the answers (groups) belonging to the cluster are talking about. At the same time, the cluster name becomes a name indicating the answer (group). In other words, by reading the cluster name, respondents can understand what kind of content is included in all the answers (groups) belonging to the cluster with the cluster name.

In this way, the cluster name is a name that expresses the contents of the cluster (answers (group)) using a short phrase, so it is difficult for viewers of the cluster name (respondents, etc.) to understand the contents of the cluster (answers (group)). It is an effective means to do so.

The number N1 (for example, the upper limit number) of words calculated by the cluster name calculation means 38c can be set, for example, by the clustering condition setting means 38e.

The representative answer calculating means 38d calculates a representative answer. Specifically, for each cluster (cluster identification information), the representative answer calculation means 38d selects from among the answers stored in the answers 34d in the cluster table 34 those that are close to the center of gravity of the cluster (that is, have a meaning). N2 (for example, N2=3) answers are calculated. At this time, a representative answer may be calculated by taking into account the number of characters in each answer. For example, answers with more characters than the first threshold, answers with fewer characters than the second threshold (second threshold < first threshold), and answers with the number of characters between the first and second thresholds. It may be calculated as a representative answer.

The representative answers (N2 answers, also referred to as central answers) calculated as described above represent the tendency of the answers (group) belonging to the cluster. Note that the representative answer refers to an answer (group) that is selected from a group of answers belonging to a certain cluster and is expected to most ``represent'' that ``answer tendency.'' Since the representative answer calculated as above is considered to represent the tendency of the content of the cluster (response (group)), viewers of the representative answer (respondents, etc.) ), it is possible to understand more deeply the contents of the cluster along with the cluster name.

The number N2 of answers calculated by the representative answer calculation means 38d can be set, for example, by the clustering condition setting means 38e.

The clustering condition setting means 38e sets clustering conditions input from the input means 35, for example. The set clustering conditions are stored in a storage unit such as the HDD 37 or the RAM of the control unit 38. The clustering conditions are conditions mainly used during clustering by the clustering execution means 38a.

The clustering conditions include, for example, the number of clusters that can be grouped together by the clustering execution means 38a (for example, the upper limit number), the number N1 of words calculated by the cluster name calculation means 38c (for example, the upper limit number), and the number N1 of words that can be calculated by the cluster name calculation means 38c (for example, the upper limit number). There are the number N2 of answers to be calculated, a predetermined timing at which the clustering execution means 38a executes clustering, etc.

[Example of operation of questionnaire system 10]
Next, an example of the operation of the questionnaire system 10 of this embodiment will be described with reference to FIG. 6.

FIG. 6 is a flowchart for explaining an example of the operation of the questionnaire system 10.

[Example of operation to display cluster screen]
First, an example of the operation of displaying a cluster screen on the display 21 of each answerer terminal 20 and the display 41 of the questioner terminal 40 will be described.

First, a question giver (e.g., a lecturer), in classroom A, sends information (information) to respondents (plurality) in classroom A to obtain a questionnaire response form registered in advance in the server device 30 (questionnaire management DB 32). the URL of the server device 30 and the reception identifier).

Next, each respondent in classroom A starts the answering application program installed on the respondent terminal 20 that each respondent owns, and inputs the URL of the server device 30 and the reception identifier that were communicated by the person asking the question. access the server device 30, if there is an authentication setting, perform an authentication operation to log in, obtain the answer form associated with the input reception identifier from the server device 30, and use the obtained answer form. is displayed on the display 21 of the respondent terminal 20 (step S10). FIG. 7 is an example of the answer form 21a displayed on the display 21 of the answerer terminal 20. Note that inputting the URL of the server device 30 may be omitted.

Next, the respondent who has the respondent terminal 20 on which the answer form 21a is displayed on the display 21 inputs an answer to the answer form 21a displayed on the display 21 (step S12). Typically, a respondent who has a respondent terminal 20 on which an answer form 21a is displayed on the display 21 displays a software keyboard (not shown) on the display 21, and uses the software keyboard on the operation unit 24. Enter the answer by operating through (flick input). The input answer is displayed in the answer input column 21a1 displayed on the display 21 (answer form 21a). Note that the input answer is typically text (letters, numbers, symbols, etc.).

Next, when the respondent performs a predetermined operation via the operation unit 24, the answer (answer data) input in step S12 is transmitted to the server device 30 (step S14). In other words, the answer will be posted. At that time, authentication information may be sent along with the answer.

Next, the server device 30 (communication unit 36) receives the answers (as well as the reception identifier and authentication information) sent from each respondent terminal 20 (step S16). As shown in FIG. 4, the received answers are associated with answer numbers and accumulated (stored) in the answerer submission data management DB 33 (step S18). Note that the answer number is incremented each time one answer is accumulated.

Next, the server device 30 (clustering execution means 38a) analyzes the answers (groups) accumulated in the respondent submission data management DB 33 at a predetermined timing and classifies them into a plurality of clusters (combines them into a plurality of clusters). (clustering) is executed (step S20). The predetermined timing is, for example, the timing when a predetermined number (for example, 300) of answers are accumulated in the respondent submission data management DB 33, or the timing when a predetermined time (for example, 10 seconds) has elapsed. The predetermined timing (for example, a predetermined number or a predetermined time) can be set by, for example, the clustering condition setting means 38e.

The classification results (clustering results) of the answers are stored in the cluster table 34 (cluster identification information 34a, answers 34d), for example, as shown in FIG.

Next, the server device 30 (answer number counting means 38b) counts the number of answers belonging to each cluster (cluster identification information) (step S22). The counted number of answers is stored in the cluster table 34 (number of answers 34b), for example, as shown in FIG.

Next, the server device 30 (cluster name calculation means 38c) calculates a cluster name for each cluster (cluster identification information) (step S24). The calculated cluster name is stored in the cluster table 34 (cluster name 34c), for example, as shown in FIG.

Next, the server device 30 transmits the cluster screen display data to each of the questioner terminal 40 and the plurality of answerer terminals 20 (step S26).

FIG. 8 is an example of cluster screen display data.

As shown in FIG. 8, the cluster screen display data includes items such as cluster identification information, number of answers, and cluster name. The cluster identification information, number of answers, and cluster name in the cluster screen display data are, for example, read from the cluster table 34 (cluster identification information 34a, number of answers 34b, cluster name 34c).

Further, the server device 30 transmits the self-answer affiliation cluster identification information to each of the plurality of respondent terminals 20. The self-answer belonging cluster specifying information is information for specifying the cluster to which the answer sent by the self (respondent terminal 20) in step S14 belongs, and is, for example, cluster identification information. An example in which the self-answer belonging cluster identification information is cluster identification information (cluster 3) will be described below.

Next, each respondent terminal 20 receives cluster screen display data and self-answer belonging cluster identification information transmitted from the server device 30 (step S28). Similarly, the questioner terminal 40 also receives cluster screen display data transmitted from the server device 30.

Next, each respondent terminal 20 (display control means 23a) displays the cluster screen 21b on the display 21 based on the cluster screen display data received in step S28 (step S30). The same applies to the questioner terminal 40.

FIG. 9 is an example of the cluster screen 21b.

The cluster screen 21b includes the classification results of the answers. Specifically, as shown in FIG. 9, the cluster screen 21b displayed on the display 21 of the respondent terminal 20 includes cluster symbol images (also referred to as cluster balloons) C0 to C8, the total number of answers 21b1, and the cluster to which the self-answer belongs. It includes an instruction display 21b2. On the other hand, although not shown, the cluster screen 21b displayed on the display 41 of the questioner terminal 40 includes cluster symbol images (also referred to as cluster balloons) C0 to C8 and the total number of answers 21b1. That is, the cluster screen 21b displayed on the display 41 of the question-asker terminal 40 does not include the self-answer affiliation cluster indication display 21b2.

Note that in FIG. 9, the cluster symbolic images C5 to C8 drawn outside the rectangle representing the outer shape of the display 21 are displayed on the display 21 by scrolling.

The cluster symbolic image C0 is an image that symbolizes the cluster identified by the cluster identification information (cluster 0) in the cluster screen display data received from the server device 30. Includes the number of matched answers (8) and cluster name (delicious x salt).

Similarly, the cluster symbolic image C1 is an image symbolizing the cluster identified by the cluster identification information (cluster 1) in the cluster screen display data received from the server device 30. This includes the number of responses associated with 1) (61) and the cluster name (curry x rice x hot).

The same applies to cluster symbolic images C2 to C8.

The size of the cluster symbolic image changes depending on the number of answers belonging to the cluster symbolized by the cluster symbolic image. For example, a cluster symbol image that symbolizes a cluster with a large number of answers is displayed in a larger size.

Each respondent can grasp the tendency of all answers without reading all the answers by reading the classification results of the answers displayed on the display 21, for example, the cluster name displayed on each cluster symbol image. I can do it.

The total number of responses 21b1 is the total number of responses in the cluster screen display data received from the server device 30.

The self-answer belonging cluster indication display 21b2 is a display pointing to the cluster (cluster symbol image) to which the answer that the self (respondent terminal 20) sent in step S14 belongs, and for example, as shown in FIG. 9, "YOU" and an arrow are displayed. This is an image that combines.

The self-answer belonging cluster indication display 21b2 indicates the cluster (here, cluster symbolic image C3) specified by the self-answer belonging cluster specifying information (here, cluster identification information (cluster 3)) received from the server device 30. is displayed near the cluster (here, the cluster symbolic image C3) (see FIG. 9).

By looking at the self-answer affiliation cluster indication display 21b2 displayed on the display 21 together with the cluster symbolic image, each respondent can determine the cluster (cluster symbolic image) to which the answer that he/she (respondent terminal 20) sent in step S14 belongs. can be grasped instantly.

[Example of operation to display additional answer symbol image]
Next, an example of the operation of displaying the additional answer symbolic image on the display 21 (cluster screen) of each answerer terminal 20 and the display 41 (cluster screen) of the question-asker terminal 40 will be described.

FIG. 10 is a flowchart for explaining an example of the operation of displaying the additional answer symbolic image. In FIG. 10, the same processes as those in FIG. 6 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The process shown in FIG. 10 is executed after the process shown in FIG. 6, for example.

First, the response form is displayed on the display 21 of the respondent terminal 20 (step S10).

Next, the respondent who has the respondent terminal 20 on which the answer form 21a is displayed on the display 21 inputs an answer to the answer form 21a displayed on the display 21 (step S12).

Next, by operating the confirmation button B (or a button equivalent to this) displayed on the display 21 (answer form 21a) via the operation unit 24, the answer data) is transmitted to the server device 30 (step S14). In other words, the answer will be posted.

Next, the server device 30 (communication unit 36) receives the answers (as well as the reception identifier and authentication information) sent from each respondent terminal 20 (step S16). Hereinafter, this received answer may be referred to as a new answer. As shown in FIG. 4, the received answers are associated with answer numbers and accumulated (stored) in the answerer submission data management DB 33 (step S18).

Next, the server device 30 (clustering execution means 38a) executes a process (clustering) of analyzing the new answers accumulated in the respondent submission data management DB 33 and classifying them into clusters at a predetermined timing (step S20). .

The classification results (clustering results) of the answers are stored in the cluster table 34 (answers 34d).

Next, the server device 30 transmits the additional answer symbolic image display data to each of the plurality of answerer terminals 20 and questioner terminals 40 (step S32).

Next, a modification will be explained.

FIG. 19 is a schematic configuration diagram of the questionnaire system 10A (modified example).

In the above embodiment, an example using one server device 30 has been described, but the present invention is not limited to this. For example, as shown in FIG. 19, a questionnaire server 30A and a response analysis server 30B may be used. In this case, the answer analysis server 30B is made to take charge of the functions of the clustering execution means 38a, the number of answers counting means 38b, the cluster name calculation means 38c, the representative answer calculation means 38d, and the clustering condition setting means 38e, and the questionnaire server 30A is responsible for the functions of It is possible to have them in charge of functions.

Note that the questionnaire server 30A and the response analysis server 30B may be installed on one server device, or may be installed on separate server devices.

Furthermore, when using multiple survey servers 30A, multiple response analysis servers 30B may be used for each of the multiple survey servers 30A, or one response analysis server 30B may be used for each of the multiple survey servers 30A. Good too.

Further, in the above embodiment, an example has been described in which a cluster screen including a cluster symbol image is used as the cluster screen, but the present invention is not limited to this.

For example, as the cluster screen, a list-type cluster screen as shown in FIG. 20 may be used.

Further, in the above embodiment, an example has been described in which the questioner of the questionnaire is a lecturer and the respondent of the questionnaire is a student, but the present invention is not limited to this. The question giver may be someone other than the lecturer (for example, an event organizer), and the answerer may be someone other than a student (for example, an event participant).

Further, in the above embodiment, an example in which each respondent terminal 20 exists in the same location (inside classroom A) has been described, but the present invention is not limited to this. For example, each respondent terminal 20 may not be located at the same location, but may be located at separate locations separated from each other.

Further, in the above embodiment, an example in which a smartphone is used as the respondent terminal 20 has been described, but the present invention is not limited to this. For example, the respondent terminal 20 may be a portable small computer such as a tablet PC or a notebook PC, or another computer.

Further, a specific word (for example, ``Omoiyari'') inputted by the instructor or the like from the input means 35 may be used as the clustering condition set by the clustering condition setting means 38e. For example, when converting words into vectors, weighting may be applied to the word vector of a specific word (for example, ``Omoiyari'') input by the instructor or the like from the input means 35.

Further, in the above embodiment, an example has been described in which N1 words expressing the tendency of answers (groups) belonging to a cluster are used as cluster names, but the present invention is not limited to this.

That is, the cluster name may be any display that represents the tendency of the answers (groups) belonging to the cluster, and may be, for example, a representative answer calculated by the representative answer calculating means 38d. In other words, the cluster name is not limited to a word, but may be a sentence. Further, in the above embodiment, an example has been described in which the answer input at each respondent terminal 20 is a character (sentence) input in the answer input field 21a1, but the answer is not limited to this. The answer entered at each respondent terminal 20 includes identification information that identifies the item selected from the options (for example, 5 occupations) and the characters (text) entered in the answer input field 21a1. It may also be a combination. In other words, the answer may be any answer that includes characters (sentences).

In this case, by first narrowing down the answers based on the options and then performing clustering for each option, more accurate analysis becomes possible.

Clustering may also be performed taking posting time into consideration. For example, clustering may be performed only on answers (groups) posted between 15:10 and 15:50. This can be realized, for example, by setting the time for performing clustering (for example, 15:10 to 15:50) as the clustering condition by the clustering condition setting means 38e.

Further, in the above embodiment, an example has been described in which a cluster symbolic image including the number of answers and a cluster name is used as a cluster symbolic image, but the present invention is not limited to this. For example, a cluster symbolic image containing only a cluster name may be used as the cluster symbolic image. In other words, the number of answers may be omitted.

This modification also provides the same effects as the above embodiment.

All of the numerical values shown in the above embodiments are merely examples, and it goes without saying that other appropriate numerical values can be used.

The above embodiments are merely illustrative in all respects. The present invention is not interpreted to be limited by the description of the above embodiments. The invention may be embodied in various other forms without departing from its spirit or essential characteristics.
