A questionnaire subject extraction method (apparatus) according to the present invention is a questionnaire subject extraction method (apparatus) for extracting a questionnaire subject, and stores information on monitors that are candidates for a questionnaire subject in a monitor information storage unit. Monitor information storing step (monitor information storing means for storing information on a monitor that is a candidate for a questionnaire target), and N as a condition for extracting the questionnaire target from the first condition to the Nth condition (N ≧ 2). Extraction condition input step (means) for inputting the number of conditions, sampling number input step (means) for inputting the number of questionnaire subjects to be extracted as a sampling number, and extraction input (by means) in the extraction condition input step The conditions are applied in order from the first condition, and monitors that match the applied conditions are extracted from the monitor information storage unit. The process of the total number of the extracted monitor repeated until the sampling number, questionnaire subject extraction step of the extracted monitored questionnaire subject with (means), and having a.
[0007]
In this manner, in the extraction condition input step, the process of applying the plurality of input extraction conditions (by means) one by one in order and extracting the monitors is repeated until the number of monitors of the sampling number is extracted. Questionnaire subjects can be smoothly extracted by the number of samples.
[0008]
In the questionnaire target extraction method (apparatus), the questionnaire target extraction step (means) includes the steps of: extracting a monitor meeting the n-th condition (2 ≦ n ≦ N) from the first condition to the n-th monitor -1 is extracted for monitors that have not been extracted under any of the conditions of -1, and whether or not the total number of monitors extracted under the extraction conditions of the first to n-th conditions has reached the sampling number If it is determined that the total number of the extracted monitors has reached the sampling number, the extracted monitors may be set as a subject of the questionnaire.
[0009]
As described above, when the monitor is extracted under the n-th condition, the monitor is not extracted under the respective conditions from the first condition to the (n-1) -th condition. This is efficient because redundant monitors are not extracted redundantly.
[0010]
In the questionnaire target extraction method (apparatus), the monitor information storage unit stores a flag indicating whether or not the monitor has been extracted, and the questionnaire target extraction step (unit) includes a first step. A flag is set for a monitor extracted in accordance with one of the extraction conditions from the condition to the (n-1) th condition. When a monitor is extracted according to the nth condition, extraction is performed for monitors for which no flag is raised. May be performed.
[0011]
As described above, a flag indicating whether or not a monitor has been extracted is stored in the monitor information storage means, and a flag is set for the extracted monitor. Monitors that have already been extracted in the extraction process (1) can be excluded from the targets of extraction.
[0012]
In the questionnaire subject extraction method (apparatus), the questionnaire subject extraction step (means) may include the step of: if the total number of monitors extracted from the first condition to the n-th condition exceeds the sampling number, The monitors randomly selected from the monitors extracted by the above and the monitors extracted under the first to n-1th conditions are set as questionnaire subjects, and the number of questionnaire subjects is equal to the sampling number. May be characterized.
[0013]
When the number of monitors extracted in this way exceeds the number of samplings, the monitors extracted under the first to (n-1) th conditions are set as subjects of the questionnaire, and the last extracted condition ( By randomly selecting the monitors extracted under the (n-th condition) as questionnaire subjects, the number of questionnaire subjects is adjusted to the number of samplings, and the monitors previously extracted (first (The monitor extracted from the condition (1) under the (n-1) th condition) can be extracted as the subject of the questionnaire. By adopting such a method (configuration), by specifying the extraction condition to be prioritized as the condition to be applied first, it is possible to reliably secure a monitor that meets the extraction condition to be prioritized as a questionnaire subject. it can.
[0014]
The questionnaire subject extraction method (apparatus) is configured such that when the total number of monitors extracted under the respective extraction conditions from the first condition to the N-th condition does not reach the sampling number, the input extraction condition is used. The method may further include a result display step (means) for displaying that the questionnaire subject of the sampling number cannot be extracted.
[0015]
If the total number of monitors extracted under the respective extraction conditions from the first condition to the N-th condition does not reach the sampling number, it is necessary to input new extraction conditions or change the sampling number. Thus, it is preferable to display that the questionnaire subject of the sampling number cannot be extracted.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of a questionnaire subject extraction apparatus according to the present invention will be described in detail with reference to the drawings.

[0017]
FIG. 1 is a block diagram illustrating a configuration of a questionnaire target extraction device 1 according to the embodiment. The questionnaire target extraction device 1 includes a monitor information storage unit (hereinafter, referred to as a “monitor resource DB”) 11 that stores information on monitors that are candidates for the questionnaire target, and an extraction condition input for inputting extraction conditions of the questionnaire target. Means 12, a sampling number input means 13 for inputting a sampling number of the questionnaire, a questionnaire target extraction means 14 for extracting a questionnaire target from the monitor resource DB 11 based on the extraction condition input by the extraction condition input means 12, Questionnaire output means 15 for outputting information on the questionnaire extracted by the questionnaire extraction means 14.
[0018]
The monitor resource DB 11 is a database that stores information on monitors that are candidates for a questionnaire target. FIG. 2 is a diagram illustrating an example of data stored in the monitor resource DB 11. The monitor resource DB 11 stores data on items such as “monitor ID”, “name”, “sex”, “age”, “marriage calendar”, and “flag”. “Monitor ID” is an identifier for specifying a monitor. A monitor is a person who has been registered in advance by agreeing to answer a questionnaire. “Name” is information on the name of the monitor. “Gender”, “age”, and “marriage calendar” are information on attributes of the monitor. Here, the monitor resource DB 11 stores information on gender, age, and marriage calendar, but may store other information, such as whether the user owns a car, whether he owns a house or rents a house, and the like. . Note that these pieces of information may be obtained by interviewing directly at the monitor registration and directly asking a question, or may be added with attribute information obtained by the monitor's answer to the questionnaire. The “flag” is information indicating whether or not the information has been extracted by the questionnaire target extraction means 14, and “0” indicates that it has not been extracted, and “1” indicates that it has already been extracted.
[0019]
The extraction condition input means 12 has a function of inputting a plurality of extraction conditions for extracting as a questionnaire subject. The relationship between a plurality of extraction conditions input here will be described. For convenience of explanation, the plurality of input extraction conditions are referred to as a first condition, a second condition,..., An N-th condition. The plurality of input extraction conditions satisfy the first condition, satisfy the second condition, and extract monitors that satisfy the N-th condition as questionnaire subjects. Rather than being applied, it is applied with priority from the first condition. That is, first, a monitor that satisfies the first condition is extracted, and if the extracted number of monitors reaches the number of samples, the second to Nth conditions are not applied. If the number of monitors extracted under the first condition does not reach the number of samplings, then a monitor that meets the second condition is extracted, and the monitor extracted under the first condition and the monitor extracted under the second condition If the total number of monitored monitors reaches the sampling number, the third to Nth conditions are not applied. As described above, the plurality of input extraction conditions have a priority, and are the first condition, the second condition,..., The N-th condition in descending order of the priority.
[0020]
The sampling number input means 13 has a function of inputting the number of monitors extracted as a questionnaire subject as the number of samplings.
[0021]
The questionnaire target extraction means 14 has a function of extracting a monitor that matches the input extraction condition from the monitor resource DB 11 as a questionnaire target. The questionnaire target extraction unit 14 includes a monitor extraction unit 14a. The monitor extracting unit 14a has a function of extracting a monitor that meets a predetermined extraction condition. The questionnaire subject extraction means 14 sequentially applies the plurality of input extraction conditions, extracts monitors matching the respective conditions by the monitor extraction means 14a, and extracts the same number of monitors as the number of samples as the questionnaire subjects. It has a function to do. The detailed flow of extracting the questionnaire target by the questionnaire target extraction unit 14 will be described when describing the operation of the questionnaire target extraction apparatus 1 according to the present embodiment.
[0022]
The questionnaire subject output means 15 has a function of outputting the monitor information extracted as the questionnaire subject by the questionnaire subject extraction means 14.
[0023]
It should be noted that the questionnaire target extraction device 1 according to the present embodiment can be configured by a normal personal computer. The extraction condition input unit 12 and the sampling number input unit 13 correspond to input devices such as a keyboard and a mouse, and the questionnaire subject output unit 15 corresponds to a display and a flexible disk drive for writing data. The monitor resource DB 11 can be configured by storing monitor information on a hard disk, and the questionnaire target extracting means 14 is realized by causing a CPU to execute a program describing a step of extracting a questionnaire target. Is done. The program is usually stored in a storage medium such as a hard disk or a flexible disk, expanded in a memory, and executed.
[0024]
Next, the operation of the questionnaire target extraction device 1 according to the embodiment will be described, and also the questionnaire target extraction method according to the embodiment of the present invention will be described. FIG. 3 is a flowchart illustrating the operation of the questionnaire target extraction device 1 according to the embodiment.
[0025]
First, information on a monitor that is a candidate for a questionnaire target is stored in the monitor resource DB 11 (S10). Monitors may be recruited on the Internet website, or may be individually visited and interviewed. If the monitor is registered on the website, the attribute information input by the monitor itself can be stored in the monitor resource DB 11 as it is, which is efficient. The method for extracting a questionnaire target according to the present embodiment is a method for extracting a monitor from the monitor resource DB 11, and the step S10 of storing monitor information in the monitor resource DB 11 extracts the questionnaire target according to the present embodiment. It is a preparation stage for.
[0026]
Next, an extraction condition for extracting a questionnaire target and a sampling number to be extracted are input (S12). Here, as the extraction conditions, N conditions of a first condition, a second condition,..., An Nth condition are input in order from the condition having the highest priority. As the extraction condition, it is preferable to input information on the attribute of the monitor. For example, conditions such as “age: 30 or older” and “sex: female” are input as extraction conditions. The input extraction conditions and the sampling number are input to the questionnaire target extraction means 14, and the questionnaire target extraction means 14 extracts the questionnaire target based on the extraction conditions. First, the questionnaire subject extraction means 14 searches the monitor resource DB 11 by the monitor extraction means 14a, and extracts a monitor that meets the first condition (S14). For example, when the monitor resource DB 11 shown in FIG. 2 is searched under the condition “age: 30 years or older”, monitors with monitor IDs: 1001 and 1002 are extracted. Next, the monitor extracting means 14a sets a flag of the monitor extracted in accordance with the extraction condition (S16). That is, the flag is set to “1” (see FIG. 2). This flag is all set to “0” before the questionnaire target extraction unit 14 extracts the questionnaire target. The timing of setting the flag to “0” may be before the extraction of the questionnaire target or after the extraction of the questionnaire target is completed.
[0027]
Next, the questionnaire subject extraction unit 14 compares the number of monitors extracted by the monitor extraction unit 14a with the sampling number (S18). Here, the number of monitors extracted under the first condition is compared with the number of samples. If the extracted number of monitors is equal to the number of samplings, the extraction of the questionnaire target ends, and information on the monitor extracted as the questionnaire target is output (S22). If the number of monitors extracted is larger than the number of samplings, monitors for the number of samplings are randomly selected from the monitors extracted under the first condition (S20), and the selected monitors are set as questionnaire subjects. . Then, the monitor information extracted as the questionnaire target is output (S22). If the number of extracted monitors is smaller than the number of samplings, the process proceeds to the next condition (S26) and monitors are extracted (S14). In this case, since the monitor has been extracted under the first condition, the questionnaire subject extracting means 14 extracts the monitor under the second condition by the monitor extracting means 14a (S14). At this time, the monitor extracted before the extraction under the second condition, that is, the monitor extracted under the first condition is excluded from the target of the extraction under the second condition. Since the flag of the monitor extracted under the first condition is “1”, the extraction is performed on the monitor whose flag is “0”.
[0028]
Next, the questionnaire subject extraction means 14 sets a flag on the monitor extracted according to the second condition (S16). That is, the flag of the extracted monitor is set to “1”. Subsequently, the questionnaire subject extraction unit 14 compares the total number of monitors extracted under each of the first condition and the second condition with the sampling number (S18). The total number of monitors extracted can be easily specified by counting the number of monitors whose flag is “1”. If the extracted number of monitors is equal to the number of samplings, the extraction of the questionnaire target ends, and information on the monitor extracted as the questionnaire target is output (S22). When the number of extracted monitors is larger than the number of samplings, a monitor is randomly selected from monitors extracted under the second condition (S20), and the selected monitor and the monitor extracted under the first condition are selected. Is equal to the number of samples. Then, the extracted monitor is set as a questionnaire target, and information of the monitor extracted as the questionnaire target is output (S22). If the number of extracted monitors is smaller than the number of samplings, monitors are extracted under the following conditions. Here, since the monitor has been extracted under the second condition, the monitor extracting means 14a extracts the monitor under the third condition (S14). Until the total number of monitors extracted in this way becomes equal to or greater than the sampling number, the monitor is repeatedly extracted by sequentially applying the conditions of lower priority. Then, when the extracted number of monitors is equal to or greater than the sampling number, the information of the questionnaire target is output (S22), and the operation of the questionnaire target extraction device 1 according to the present embodiment ends. If the monitor of the sampling number cannot be extracted even when all the input conditions are applied, it is displayed that the monitor of the sampling number cannot be extracted under the input extraction conditions. That is, in step S18, the total number of extracted monitors is compared with the number of samplings. As a result, if the number of extractions is smaller than the number of samplings, it is determined which condition has been used to extract monitors at the present stage ( S24). It is determined whether the n-th condition from which the monitor has been extracted is the N-th condition having the lowest priority among the input conditions. If the n-th condition is the N-th condition, an extraction condition that can be applied more than that Since there is no questionnaire, it is displayed that it is not possible to extract the questionnaire subject of the sampling number (S28), and the operation of the questionnaire subject extraction device 1 according to the present embodiment ends. If the n-th condition is not the N-th condition with the lowest priority, the process proceeds to the next condition (S26) and monitors are extracted, as described in the above flow.
[0029]
In the questionnaire target extraction apparatus 1 according to the present embodiment, a plurality of extraction conditions are input by the extraction condition input means 12, and the plurality of extraction conditions are sequentially applied by the questionnaire target extraction means 14 to extract the monitor and extract the monitor. By repeating this process until the total number of monitors reaches the sampling number, it is possible to smoothly extract the questionnaire subjects matching the extraction conditions by the sampling number.
[0030]
Similarly, the questionnaire subject extraction method according to the present embodiment also applies the plurality of extraction conditions input in the extraction condition input step in order to extract monitors and the total number of monitors extracted reaches the sampling number. By repeating the above steps, it is possible to smoothly extract the questionnaire subjects matching the extraction conditions by the number of samplings.
[0031]
As described above, the questionnaire target extraction device and the questionnaire target extraction method of the present invention have been described in detail with reference to the embodiments. However, the present invention is not limited to the above embodiments.
