1 is a block diagram schematically showing each configuration of a restaurant data collection system based on a question card for a survey according to the present invention.

Referring to FIG. 1 , a system for collecting data on a restaurant based on a question card for a survey according to the present invention is a content including a review on a restaurant by a user terminal 200 connected through a network. (contents) is registered, and includes a server 100 that provides the registered content back to the user terminal (200).

The user terminal 200 according to the present invention accesses the server 100 through a network. The server 100 may provide predetermined application software (application, app, hereinafter 'app') to which the user terminal 200 can access. An app provided by the server 100 is installed in the user terminal 200 , and information provided by the server 100 may be displayed on the screen of the user terminal 200 through the app.

The user terminal 200 according to the present invention accesses the server 100 and registers contents including information such as reviews on restaurants. The content registered by the user terminal 200 includes, in addition to the review, the restaurant's name, address, contact information, map-based restaurant location, food or photos of the restaurant, and the rating of the restaurant. The user terminal 200 registers contents about the restaurant experienced by the user. The user terminal 200 may obtain a reward according to the number of registered contents. The reward may be an increase in the number of readings of the restaurant and other restaurant contents registered by the person. The server 100 according to the present invention, as an embodiment, when the user terminal 200 registers as a member through the app, may limit the number of times to read the content to a predetermined specific number of times. The server 100 gives an additional point to the number of readings according to the number of times the user terminal 200 registers the contents or responds to the question card, and increases the number of readings according to the added points to register and query the contents of the user terminal 200 Facilitate and elicit responses to cards.

The server 100 according to the present invention may provide content registered from the user terminal 200 to the user terminal 200 as well as a plurality of other user terminals 200 .

The server 100 according to the present invention includes a content registration unit 10 for storing and managing content registered by the user terminal 200 by accessing the server 100 .

The server 100 according to the present invention includes a question card providing unit 20 that accesses the server 100 and provides a question card for a survey to the user terminal 200 that has registered the content. The content entered and registered by the user terminal 200 inevitably includes subjective information.

The question card according to the present invention is for further collecting standardized information in addition to the information registered by the user terminal 200 . The question card may be imaged so that a question and a view according to the question can be displayed on a display device including a touch screen of the user terminal 200 . The user may transmit a response to the question to the server 100 by clicking or touching any one of the views displayed on the screen of the user terminal 200 .

The question card providing unit 20 according to the present invention includes a plurality of different types of question cards. Each of the plurality of question cards includes different questions. An embodiment of the question cards and the questions and answers provided by the question cards will be described later together with the accompanying drawings.

The plurality of question cards according to the present invention may each have a serial number so that the order of provision to be provided to the user terminal 200 is determined. For example, when the question card providing unit 20 is provided with five question cards, each question card provides a serial number such as question card 1, question card 2, question card 3, question card 4, and question card 5. can be provided The question card providing unit 20 may provide the question card to the user terminal 200 sequentially from the question card 1 to the question card 5 according to the providing order. The question card providing unit 20 may provide the question card from question card 1 to the user terminal 200 again after question card 5 .

The user terminal 200 provided with the question card may select an answer corresponding to the question included in the question card, and the selected answer is transmitted to the server 100 and the user terminal 200 is transmitted by the question card providing unit 20 It can respond according to the transmission of its answer to a question. The server 100 that has received the answer stores information about the answer in the content registration unit 10, and the stored answer is collected and managed as content related to the restaurant together with the review registered by the user terminal 200. The serial number for the question card provided by the question card providing unit 20 and the order of providing the question card may be input and determined by the administrator.

The question card providing unit 20 according to the present invention may provide any one of a plurality of question cards according to the order of provision when providing the question card to the user terminal 200 in which the content is registered. When the server 100 receives a response to the provided question card, the server 100 may end content collection from the user terminal 200 . That is, the user terminal 200 that has registered content for one restaurant transmits only an answer to one question card to respond to the question card.

On the other hand, when the user terminal 200 cannot answer the question provided by the provided question card, it is possible to pass the response to the provided question card. The case where it is impossible to answer a question may include, for example, a case in which the answer to the question is unknown or cannot be remembered. The question card may include a clickable pass button to pass the answer.

The question card providing unit 20 according to the present invention, when the user terminal 200 passes the response to the question card, provides the question card of the next providing sequence again. When the user terminal 200 passes the question card provided again, the question card of the next provision order is provided again. When the user terminal 200 passes the question card provided again again, the server 100 does not store the subsequent response from the user terminal 200 . The aggregation of inaccurate information can be prevented according to the above-described algorithm.

Meanwhile, as it is possible for the user terminal 200 to pass the provided question card, referring to Table 1 below, the number of responses may be different for each question card. The server 100 according to the present invention further includes a response number counting unit 30 for counting the number of responses according to the question card stored in the content registration unit 10 .

The number of responses counting unit 30 according to the present invention may count the number of responses stored for each question card in the content registration unit 10 to calculate from the question card with the smallest number of responses to the question card with the largest number of responses. The number of responses counting unit 30 extracts a question card having a smaller number of responses than other question cards when there is a question card having a smaller number of responses than other question cards. When the number of responses counting unit 30 calculates and extracts a question card with a smaller number of responses, the number of times (eg, In Tables 1 and 2 below, 7 times) may be pre-designated.

The number of responses counting unit 30 according to the present invention, in the situation as shown in Table 1 below, the question card 1 was provided to the same or different user terminals 200 a total of 7 times, and for questions from all user terminals 200 Answers were received, Question Card 2 had 5 passes, so only 2 responses were received, Question Card 3 received 3 responses according to 4 passes, Question Card 4 received 4 responses according to 3 passes Responses received, question card 5 counts 6 responses received according to one pass. The number of responses counting unit 30 extracts the question card and information on the question card that have received fewer responses for each question card, and transmits the extracted question card and information on the question card to the question card providing unit 20 .

<Table 1>

The question card providing unit 20 according to the present invention, as described above, when providing the question card to the user terminal 200, provides it sequentially according to the sequence number provided by the question card in a given order. On the other hand, the question card providing unit 20 that has received the information on the question card extracted from the number of responses counting unit 30 takes precedence over the question card determined in the order of providing according to the serial number, the question card having a smaller number of responses is provided first.

Referring to Table 2 below, the question card providing unit 20 sends the question card 2 having the lowest number of responses to the question card 1 compared to other question cards calculated, extracted and received by the response number counting unit 30 . First, it is provided to the user terminal 200 . Thereafter, when a response to question card 2 is received, the number of responses of question card 2 and the number of responses of question card 3 are equal to each other, so that contention in the order of providing according to the number of responses occurs. In this case, the order of providing according to the serial number is applied again, so that the question card 2 is first provided to another user terminal 200, and when a response to the question card 2 is received, the question card 3 is sent to the next user terminal 200 is provided As such, the information can be balanced as the question cards with fewer responses are provided first, taking precedence over the order of presentation according to the serial number. can have an effect.

<Table 2>

On the other hand, the server 100 according to the present invention, as another embodiment, receives the answer to the question card from the user terminal 200 and receives information that is incompatible with each other in the information stored in the content registration unit 10 It may further include a true false extraction unit 40 to determine. The true false extracting unit 40 extracts information that has received incompatible responses from among the responses to the question card stored in the content registration unit 10 . At this time, the incompatible response is a response to the question card with the issue of true and false, for example, when the question of the question card is the question of whether there is a parking space, which user terminal 200 has a parking space? Transmitting an answer, the other user terminal 200 means responses in the case of transmitting an answer that there is no parking space.

The true false extracting unit 40 extracts information on the question card that has received the incompatible response, and then transmits the information on the question card including the extracted incompatible response to the question card providing unit 20 .

The question card providing unit 20 that has received the information on the question card including the mutually incompatible answers, gives priority to the question card including the received incompatible answer over the providing sequence according to the serial number to the user terminal 200 ) can be provided. Therefore, the question cards having the issue of true and false are provided to the other user terminals 200 in preference to a predetermined order of providing, so as to collect accurate information on restaurants. When the question card providing unit 20 provides the question card to the user terminal 200, when question cards including incompatible responses compete with each other, similar to the question card provision according to the number of responses described above, the order of provision Among the competing question cards, priority may be applied according to the order of provision according to the serial number and provided to the user terminal 200 .

On the other hand, the true-false extraction unit 40 can further calculate and determine the weight of the question card having the issue of true and false, and among the question cards with incompatible responses, When the weights are similar, it can be judged as a question card with greater true and false issues. For example, as described above, after calculating that the ratio of responses that there is a parking space to the question of whether there is a parking space is 60% vs 40% and 70% vs 30%, each result can be compared with each other . The true false extracting unit 40 may determine that the former (60% vs 40%) has more serious issues of true and false than the latter (70% vs 30%). The question card providing unit 20 that has received the information on the question card that is judged to have more serious issues of truth and falsehood takes precedence over the question card with more light issues of truth and falsehood. A question card having more serious issues of true and false may be provided to the user terminal 200 .
