Description

Customer Satisfaction Survey Execution System

The present invention relates to a system for performing a satisfaction survey. Specifically, the present invention relates to a system for performing a satisfaction survey on an evaluation target for arbitrary users in a public place or a store providing customer service.

With the recent development of information and communication technology, most users can easily evaluate a specific place, and the collected evaluation content is transmitted to the manager of the evaluation target and used as a means of requesting feedback. Although digital devices such as phone, e-mail, face-to-face, or tablet are often used as a collection method for customer satisfaction evaluation, the actual response rate and accuracy are low because respondents usually spend time explaining and answering the question.

In addition, such evaluation contents may be provided to other users and may affect their intention to use. Due to the influence of such rating information, there is a possibility that competitors may give false low ratings, or conversely, a problem may arise in which a person who has been rewarded may repeatedly post falsely high ratings. In the portal, such false repeated evaluation can be prevented by identifying each individual user based on the user's personal information such as resident registration number. However, unlike these portals, if you want to immediately conduct a satisfaction survey in a public place used by many people, survey participants will be reluctant to input such personal information because it can be misused for crime. will be low In addition, since it takes time to input such personal information and to be authenticated as an individual user, it is difficult to secure personal information and prevent duplicate evaluation.

Therefore, when conducting a satisfaction survey in a public place, a method is required to prevent damage caused by duplicate evaluators while preventing the survey participants from entering personal information.

The present invention is designed to filter duplicate answers by duplicate raters while collecting customer evaluations quickly and easily during a satisfaction survey without collecting sensitive personal information such as name, social security number, and phone number.

The system for performing a satisfaction survey according to an embodiment of the present invention is configured to include an apparatus for performing a survey and a server, and the apparatus for performing the survey provides the evaluation information obtained by the evaluator participating in the satisfaction survey and the appearance sensing information of the evaluator to the server. provided to, and the server calculates an evaluation result for an evaluation target based on the evaluation information received from the survey performing device and the evaluator's appearance sensing information, but within a preset period based on the evaluator's appearance sensing information It is determined whether the evaluator has repeatedly evaluated, and if it is confirmed that the evaluation is duplicated, the evaluation information written by the evaluator can be removed.

The present invention can filter out duplicate evaluators in a satisfaction survey without collecting sensitive personal information such as name, resident number, and phone number.

In addition, although not shown in the drawings, according to various embodiments, the expression input device 201 may additionally include a button for canceling a satisfaction expression selection.

2 is a diagram illustrating the configuration of a server according to an embodiment of the present invention.

As shown in FIG. 2 , the server 100 according to an embodiment of the present invention is configured to include a communication unit 110, a storage unit 120, an evaluation request unit 131, an evaluator analysis unit 132, a duplicate removal unit 133, and an evaluation information analysis unit 134. can

The communication unit 110 may use a network for data transmission/reception between the user device and the server, and the type of the network is not particularly limited. The network may be, for example, an IP (Internet Protocol) network that provides a large-capacity data transmission/reception service through Internet Protocol (IP) or an All IP network that integrates different IP networks. In addition, the network includes a wired network, a Wibro (Wireless Broadband) network, a mobile communication network including WCDMA, a High Speed Downlink Packet Access (HSDPA) network, and a Long Term Evolution (LTE) network including a mobile communication network, LTE advanced (LTE-A) ), a mobile communication network including 5G (Five Generation), a satellite communication network, and a Wi-Fi network, or a combination of at least one or more of them.

The communication unit 110 according to an embodiment of the present invention may deliver content for a satisfaction survey (eg, information on an evaluation target, a satisfaction evaluation information input screen, etc.) to the survey performing device 200 so that the evaluator can check it.

The storage unit 120 may include, for example, an internal memory or an external memory. The internal memory includes, for example, a volatile memory (eg, dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM), etc.), non-volatile memory (eg, OTPROM (one time programmable ROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (such as NAND flash or NOR flash), hard drive, or a solid state drive (SSD).

External memory is a flash drive, for example, CF (compact flash), SD (secure digital), Micro-SD (micro secure digital), Mini-SD (mini secure digital), XD (extreme digital), It may further include a multi-media card (MMC) or a memory stick. The external memory may be functionally and/or physically connected to the electronic device through various interfaces.

The storage unit 120 according to an embodiment of the present invention may store an evaluator identification value. The evaluator identification value may mean a code given based on the appearance sensing information of the evaluator to prevent negative evaluation by the same evaluator.

The evaluation requesting unit 131 may manage satisfaction survey items for each target (eg, company and institution, etc.) requesting a satisfaction survey, and may perform a satisfaction survey with an item corresponding to each target. In addition, the evaluation requesting unit 131 may request the survey performing device 200 to perform a satisfaction survey.

According to various embodiments of the present disclosure, the evaluation requesting unit 131 may support a satisfaction survey for a plurality of subjects through one survey performing device 200 . In this case, the evaluation requesting unit 131 may periodically change the initial screen for displaying the evaluation target, and the like, so that a plurality of people can check the evaluation target in the research performing apparatus 200 .

The evaluation request unit 131 may provide star point selection data or expression selection data corresponding to satisfaction to the evaluator, and request the evaluator to input satisfaction evaluation information for the target. In addition, the evaluation request unit 131 may support the evaluator to input satisfaction evaluation information through various operations such as numerical input.

According to an embodiment, the evaluation requesting unit 131 may induce a plurality of evaluators to input evaluation information on condition that rewards such as accumulation of points and coupons are provided.

The evaluator analyzer 132 may generate and assign an identification value to an individual evaluator based on appearance sensing information about the evaluator obtained from the survey performing apparatus 200 . Later, the identification value for the individual evaluator provided by the evaluator analyzer 132 may be utilized to detect duplicate evaluators.

According to an exemplary embodiment, the evaluator analyzer 132 may obtain an evaluator's face image through a camera provided in the survey performing apparatus 200, and may determine whether the same evaluator is repeatedly evaluated based on the obtained face image. . In addition to the face image, the evaluator analysis unit 132 may receive elements such as height and body shape from the survey performing device 200, and analyze the evaluator's characteristics by using them, and may assign an identification value (eg, a code such as BSD1352). have. The identification value may be used to determine whether it is identical to a previous evaluator.

In this case, the evaluator analysis unit 132 may be set not to collect personal information such as resident registration number and phone number from the evaluator when generating an identification value for the evaluator. The present invention relates to a technology for limiting excessive repeated evaluation by the same person without collecting sensitive personal information of evaluators that can be used for crimes during a satisfaction survey. Accordingly, the evaluator analysis unit 132 of the present invention may be set not to request personal information (eg, resident registration number, address, phone number, etc.) for specifying the evaluator.

The evaluator analyzer 132 may discard the identification value generated from the evaluator's appearance sensing information when a preset time elapses. For example, the period in which the identification value is discarded may be set to 24 hours. In addition, after the individual evaluator identification values are discarded, even if the same evaluator performs reevaluation, even if the same evaluator performs reevaluation, it is not regarded as a duplicate evaluation because there is no evaluator information for identifying duplicate evaluators even if evaluation information is generated from the same evaluator. That is, the evaluator analyzer 132 may set the minimum reference time for not being regarded as a duplicate evaluation as an individual evaluator identification value discard cycle and periodically discard the evaluator identification value.

In addition, according to various embodiments, when generating an evaluator identification value, the evaluator analyzer 132 may analyze group information including the evaluator's gender and age through an image analysis algorithm. Specifically, the evaluator analysis unit 132 determines the group to which the evaluator belongs (eg, gender, age group, foreigner status, etc.) based on appearance sensing information including the evaluator's appearance image, voice, height, etc. Information can be extracted together and reflected in the evaluation information.

As a result of the evaluator analysis, when it is determined that the same evaluator participated in the duplicate evaluation, the duplicate removal unit 133 may determine the evaluation information as a negative evaluation and delete it.

According to an embodiment, the duplication removing unit 133 may determine whether an evaluator overlaps after acquiring both the evaluation information and the evaluator identification information. you can also make it

Of the two methods, below, after obtaining both evaluation information and evaluator identification information, the method of determining whether an evaluator overlaps or not, and removing the latest evaluation information when it is determined that the evaluation is duplicated, will be described in greater detail below.

According to an embodiment of the present invention, in order to limit the behavior of one evaluator continuing to participate in evaluation for a specific purpose (eg, for the purpose of maliciously slandering a specific store or for the purpose of falsely raising the rating), it is obtained by the same evaluator By removing the redundant evaluation information, it is possible to improve the reliability of the evaluation result.

To this end, the duplicate evaluator 133 may confirm the existence of the duplicate evaluator by determining whether a value identical to the previously obtained identification value exists among the evaluator's identification values obtained during the satisfaction survey. In addition, the duplicate removal unit 133 may delete evaluation information input by an evaluator determined as a duplicate evaluator so that it is not reflected in the satisfaction evaluation.

A more detailed description of the duplicate removal unit 133 will be described with reference to FIG. 3 .

3 is a diagram illustrating a configuration of a duplication removing unit according to an embodiment of the present invention.

As shown in FIG. 3 , the duplication removal unit 133 may include a service field-based determination unit 133a and a peripheral integration determination unit 133b.

First, the service field-based determination unit 133a sets different criteria for overlapping evaluation in correspondence to the service field to which the evaluation target belongs, and in response, transmits the reset value of the individual evaluator identification value discard cycle to the evaluator analysis unit 132. have. Alternatively, the service field-based determination unit 133a may apply a separate evaluation limitation period only to an additional specific service field, regardless of the period of discarding individual evaluator identification values set as a default value in the evaluator analysis unit 132 .

For example, if it is assumed that the period of discarding individual evaluator identification values set as a default value is 24 hours, the service field-based determination unit 133a classifies service fields to which such a basic value is applied and service fields to which such a basic value is not applied, and performs different evaluation Limited time periods may apply. First, in the case of satisfaction evaluation of facilities such as toilets and benches, which are generally considered to be usable several times during one day, the service field-based determination unit 133a may set the evaluation limit period to 30 minutes, and In the case of satisfaction evaluation for places that are not expected to be used more than once in a day, the default evaluation limit period (eg, 24 hours) may be applied.

The service sector-based determination unit 133a may set the evaluation limit period differently according to the characteristics of the service sector as described above, and the criteria for setting the evaluation limit period include the user's revisit cycle, the time required for one use, and the like. can be

Basically, if a customer who uses a facility or store wants to participate in a satisfaction survey more than twice during the preset evaluation limit period, the participation may be restricted or the submitted evaluation information may not be reflected because it is deleted.

The service sector-based determining unit 133a determines whether an evaluator identification value included in the evaluation information exists when new evaluation information for the first service field in which the individual evaluator identification value discard period and the evaluation limit period are set to be the same is acquired By determining whether there is a duplicate or not, it is possible to delete the evaluation information if the duplicate identification value information exists.

On the other hand, when the evaluation information for the second service field in which the evaluation limit period is set shorter than the period of discarding the individual evaluator identification value is obtained, the service field-based determination unit 133a performs a separately set evaluation even if the identification value information of the evaluator exists. If it is judged that evaluation information has been entered beyond the limited period, it is not considered as a negative evaluation by a duplicate evaluator.

The peripheral integration determiner 133b may set a plurality of investigation performing apparatuses 200 into a group, detect a negative evaluation based on evaluation information performed by the investigation performing apparatus 200 belonging to the group, and remove it.

The peripheral integration determining unit 133b may preset a plurality of irradiation performing apparatuses 200 existing within a preset distance range as one group based on the location of the one irradiation performing apparatus 200 . In addition, the peripheral integration determining unit 133b may determine that the evaluation is a duplicate evaluation when the same evaluator inputs satisfaction evaluation information more than once through an arbitrary device belonging to a group for a preset time (evaluation limitation period). Accordingly, the peripheral integration determination unit 133b may check and filter not only the duplicate evaluation through one device but also the duplicate evaluation by the same evaluator performed through any device among a plurality of devices set as a group.

Furthermore, the peripheral integration determination unit 133b may determine whether or not the evaluation is duplicated based on the moving line or the moving distance of the evaluator, and when it is determined that the evaluation is duplicated, the corresponding evaluation information may be deleted.

Specifically, the peripheral integration determiner 133b may reset the evaluation limit period by adding a time proportional to the degree of the separation distance based on the separation distance between the plurality of survey performing apparatuses. For example, it is assumed that the first irradiation performing device and the second irradiation performing device are installed at a distance of about 50 m, and the distance between the first irradiation performing device and the third irradiation performing device is about 70 m. And when it is assumed that the period (evaluation limitation period) that must elapse for the evaluator to input evaluation information through the first investigation performing device again to input evaluation information through the first investigation performing device is 30 minutes, the peripheral integration judgment Part 133b sets the elapsed period (evaluation limit period) required to input evaluation information in the second investigation performing device after inputting the evaluation information in the first investigation performing device to 5 minutes (eg, the first investigation performing device and the second It can be set to 35 minutes by adding the value calculated as the distance between the devices performing the survey is 50 m). Similarly, the peripheral integration determination unit 133b inputs the first evaluation information in the first investigation performing device and then the evaluation limit period when the third investigation performing device wants to input the second evaluation information is the first investigation performing device and the second 3 It can be set to 37 minutes by adding 7 minutes, which is a value proportional to the distance (70 m) between the 3 irradiation performing devices. In this case, it goes without saying that the formula for calculating the distance between the survey performing devices and the value proportionally added to the evaluation limit period may vary depending on the case.

The evaluation information analysis unit 134 may analyze the evaluation information input by the evaluators. According to an embodiment, the evaluation information analysis unit 134 may calculate evaluation statistical information for each evaluator group, and may filter inaccurate evaluation information.

The description of the evaluation information analysis unit 134 may be described with reference to FIG. 4 .

4 is a diagram illustrating the configuration of an evaluation information analysis unit according to an embodiment of the present invention.

As shown in FIG. 4 , the evaluation information analyzing unit 134 may include a statistical calculating unit 134a, a correlation determining unit 134b, and a filtering performing unit 134c.

The statistics calculator 134a may perform an operation of calculating statistics based on the obtained evaluation information. The statistics calculator 134a may calculate statistics according to gender and statistics according to age in response to a result value obtained by extracting evaluator group information based on the appearance sensing information of the evaluator.

Furthermore, the statistics calculating unit 134a may calculate the evaluation results for each time period as statistics. For example, the statistics calculator 134a may calculate the evaluation of the employee friendliness in the morning time period (eg, 10 o'clock to 12 o'clock) and the employee friendliness of the afternoon time period (eg, 1 o'clock to 3 o'clock), respectively. . Through this, it is possible for a company or an institution official who checks the evaluation analysis data calculated by the statistical calculation unit 134a to confirm that there is a difference in the response methods of the morning staff and the afternoon staff.

The relevance determining unit 134b may determine the relevance between the evaluation target and the evaluation content.

According to various embodiments of the present disclosure, the survey performing apparatus 200 may evaluate satisfaction in various ways. For example, according to the present invention, an evaluator may directly select an evaluation item and then assign a rating or may perform an evaluation on an object by selecting one of pre-provided example sentences. Furthermore, the evaluator may perform a more detailed and specific evaluation through a method such as voice input or writing on the touch panel. For example, the evaluator may input a rating when performing a satisfaction survey and may also input a reason for the rating.

As described above, in addition to the rating or score, more specific sentence-type evaluation information may be input from the evaluator, so that the relevance determining unit 134b can determine the correlation ratio between the sentence-shaped evaluation information and the service field of the evaluation target. do.

The association determining unit 134b may determine whether texts whose meanings are not confirmed are listed, for example, in the evaluation information in the form of sentences. Alternatively, the association determining unit 134b may check the meaning of the evaluation information in the form of a sentence to determine whether the sentence is not related to the service field of the evaluation target.

The filtering performing unit 134c may filter by deleting evaluation information having a relevance equal to or less than a reference value based on the relevance ratio confirmed by the relevance determining unit 134b. Unclear evaluation information may be filtered out through the filtering function performed by the filtering performing unit 134c.

According to various embodiments of the present disclosure, various evaluation information (e.g., ratings) including result information filtered by the filtering performing unit 134c may be provided to a manager of an evaluation target later.

Also, according to various embodiments, the acquired and filtered evaluation information may be provided to other managers in the same service field at a predetermined price.

5 is a diagram illustrating the configuration of an apparatus for performing a satisfaction survey according to an embodiment of the present invention.

As shown in FIG. 5 , the apparatus 200 for performing a satisfaction survey according to an embodiment of the present invention includes a wireless communication unit 210, an audio processing unit 220, a sensor unit 230, a camera unit 240, a usage fact authentication unit 251, and an evaluation information collection unit 242. can be configured.

The wireless communication unit 210 according to an embodiment of the present invention may transmit the evaluation information input from the evaluator to the server 100, and may receive data provided from the server 100 on the contrary.

According to an embodiment, the wireless communication unit 210 transmits the evaluator appearance sensing information to the server 100 when performing an evaluator analysis operation performed to determine whether an evaluator repeatedly performs negative evaluation, and the server 100 It is possible to receive a result of determining whether the evaluators overlap.

According to an embodiment, the wireless communication unit 210 may transmit a connection unstable signal to a temporary storage control unit (not shown) when it is determined that the communication connection state is in an unstable state, such as indicating a speed less than a reference value or not being connected to the server 100. . When the temporary storage control unit (not shown) receives the connection instability signal, it may instruct the storage unit (not shown) to immediately temporarily store the evaluation information input by the evaluator. In addition, the temporary storage control unit may control to provide the temporarily stored evaluation information to the server 100 as the communication connection with the server 100 is restored to a normal state later. Through such an operation, the present invention can support so that the evaluation information input by the evaluator is not lost.

The audio processing unit 220 may interactively convert a sound and an electrical signal, for example. At least some components of the audio processing unit may be included in the input/output interface. The audio processing unit may process sound information input or output through, for example, a speaker, a receiver, an earphone, or a microphone.

The audio processing unit 220 according to an embodiment of the present invention may receive a voice input from an evaluator to generate an evaluator identification value. Also, the audio processing unit 220 may receive an evaluation content in voice form from an evaluator in order to use it for evaluation information.

In addition, the audio processing unit 220 may output a guide voice to be provided to the evaluator when the satisfaction survey is performed.

The sensor unit 230 may, for example, measure a physical quantity or sense an operating state of the watch, and convert the measured or sensed information into an electrical signal. The sensor unit may include, for example, a gesture sensor, a barometric pressure sensor, a magnetic sensor, a proximity sensor, a color sensor (eg, an RGB (red, green, blue) sensor), a biometric sensor, a temperature/humidity sensor, an illuminance sensor, or It may include at least one of UV (ultra violet) sensors. Additionally or alternatively, the sensor unit, for example, an olfactory sensor (E-nose sensor), an EMG sensor (electromyography sensor), an EEG sensor (electroencephalogram sensor), an ECG sensor (electrocardiogram sensor), IR (infrared) ) may include a sensor. The sensor unit may further include a control circuit for controlling at least one or more sensors included therein.

The sensor unit 230 according to an embodiment of the present invention may acquire appearance sensing information required to generate an identification value for an evaluator. For example, the sensor unit 230 may perform a sensing operation through infrared rays or the like to predict the height of an evaluator who is stopped in front of the device for a satisfaction survey. Accordingly, for example, the sensor unit 230 can check the height of the evaluator, and can check whether the evaluator is a child or an adult corresponding thereto.

In addition, the sensor unit 230 may determine whether the evaluator is in proximity. According to various embodiments of the present disclosure, a satisfaction evaluation request sound and screen may be displayed only when proximity of an evaluator is determined through the sensor unit 230 .

The camera unit 240 is, for example, a device capable of capturing still images and moving images, and according to an embodiment, one or more image sensors (eg, a front sensor or a rear sensor), a lens, an image signal processor (ISP), or It may include a flash (eg, an LED or xenon lamp, etc.).

The camera unit 240 according to an embodiment of the present invention may obtain image information on the appearance of the evaluator. At this time, the obtained appearance image information may be provided to the server 100 and utilized to generate an identification value of an individual evaluator.

For reference, according to various embodiments, assuming that the apparatus 200 for performing the survey of the present invention is implemented in the same form as the expression input apparatus 201, the configuration of the audio processing unit 220, the sensor unit 230, the camera unit 240, the display unit (not shown), etc. It may be configured through a separate peripheral device instead of an integrated one.

According to an embodiment, the use fact authenticator 251 may request an evaluator to authenticate the use fact when proof of the use fact is requested. For example, the usage fact authentication unit 251 may request to perform an authentication operation such as scanning a usage receipt image or barcode. In addition, the use fact authentication unit 251 may grant the qualification of the evaluator only to the user whose use fact is authenticated.

The use fact authenticator 251 may selectively request proof of the use fact from the evaluator only in the service field. For example, the use fact authentication unit 251 selects a specific evaluation target and evaluates the satisfaction thereof when the investigation execution device 200 is installed in a place where a large number of stores or use facilities are densely located in the vicinity, such as a department store, an outlet, an airport, etc. can be performed. In this case, the use fact authentication unit 251 may allow the evaluator to select a specific evaluation target and then request authentication of the use fact for the corresponding evaluation target.
