Description

[0002] Comments evaluation method and system using user location information [

The present invention relates to a method and system for evaluating comments using user location information, and more particularly, to a method for evaluating user comments based on user location information and set location information.

Recently, as more people use smartphones to get information about restaurants, the content related to eating out (commercial content) and comments are increasing. In particular, comments have a variety of benefits, including allowing consumers to share information and helping to validate content. Specifically, the following is summarized.

Comments allow customers to share information in a variety of ways, including reviews and reviews of specific restaurants. This information not only narrows the choices for restaurants but also curiosity about restaurants that have not been visited. In addition, it has an effect of increasing the number of visitors to the business, as it affects the brand attitude and the purchase intention positively to the customer.

However, comments related to eating out do not have the above merits. Commenting on the biggest problem of commenting in commercial content is that commenting has its own economic value, which leaves false negative and positive opinions. For example, a corporation providing a financial price of an operating stock to content such as a community site, a blog or an Internet café creates a false post comment. Therefore, various attempts have been made to minimize the problems of such comments.

First of all, there is a widely known login system. The login system is a system that allows only the logged-in user to create a comment by using the login ID and password that are given after describing the personal details of a certain condition. Although the fictitious writings have been somewhat reduced due to the introduction of the above system, in this case, the use of multiple IDs is not revealed, and the effect of reducing false writings is insufficient.

As another attempt to solve the problem of comments, there has been attempted a method in which only a logged-in user can make a recommendation, or a method in which only a member class can be recommended in a certain condition of a logged-in member has been tried. However, there was a problem that the above two methods could avoid circumstantial way to evaluate the reliability of the comment, and most of the users' recommendation was not able to recommend the recommendation by subjective judgment only in the comment. Therefore, there is a limit to the conventional method as described above.

Accordingly, it is an object of the present invention to solve the above-mentioned problems of the related art, and it is an object of the present invention to confirm whether or not a comment is posted at a location where the user actually commented on the offline service content, Allows you to evaluate the reliability of comments. In addition, based on the reliability, comments can be ranked and provided in order of high reliability.

Yet another object of the present invention is to minimize the economic loss of a content provider (provider) and objectively evaluate a user's evaluation opinion, thereby forming a reliable comment culture in the Internet space.

According to an embodiment of the invention, a method of rating a comment in a comment rating system is provided. The method of claim 1,

A step of receiving user location information from the geolocation API at the user terminal in a case where there is a comment registration request from the user terminal, a step of evaluating the reliability of the comment based on the user's location information and the content location information And a ranking step of determining a ranking of a plurality of comments.

The step of receiving the user location information at the server may receive the user location information from the geolocation API at the user terminal at the server.

In the position information evaluation step, the error index and the confidence index may be determined based on the content position information and the terminal position information stored in advance in the database as the position information acquired by the user terminal. At this time, if the content position information is null, the error index and the confidence index can be determined using the predetermined position information. Also, it can be excluded from the comment evaluation method according to the present invention by setting in the content provider.

The ranking step gives the order of descending exposure from highest to lowest in the order of the highest confidence index, and the final exposure ranking can be stored in the database. In addition, the comment ranking can be configured such that data is sorted in descending order when the comment of the general user is confirmed on the web, which is the earliest when the comment having a high confidence index is displayed.

According to the method and system for evaluating comments using location information of a user according to the present invention,

1) As soon as a user posts a comment, the user can evaluate the reliability of the comment using the location information.

2) As the actual visitor's comment takes precedence, the actual visitor's opinion can be increased, and reliable information can be easily shared.

3) You can get the effect of reducing intentionally promoting and reproving users' comments.

In order to clearly explain the present invention, parts not related to the description are omitted, and like parts are denoted by like reference numerals throughout the specification.

[Preferred Embodiment of the Present Invention]

Configuration of the entire system

1 is a diagram showing the configuration of an overall system according to the present invention. 2 and 3 are exemplary diagrams for explaining storage formats of a content database (not shown) and a comment database (not shown), respectively.

1, the server 200 in the overall system according to the present invention may be connected to a plurality of user terminals 400 through a network 300 and may include a content management unit 210, a location information evaluation unit 220, A determination unit 230 and a database 100 linked to the determination unit 230.

The user terminal 400 may have an Internet browser (for example, Internet Explorer, Safari, or Opera Mobile) capable of displaying web contents provided by the content management unit 210 in the form of HTML (Hyper Text Markup Language) .

In addition, the user terminal 400 is provided with a geolocation application programming interface (API) for confirming location information. The geo location API refers to an application programming interface that inquires the location information of the user terminal 400 in the Internet browser installed in the user terminal 400. [ Here, the location information inquiry means information obtained through the location based service.

Using Geo Location API, users can inquire latitude, longitude, altitude, latitude and longitude accuracy (hereinafter referred to as accuracy) without direct manipulation, so users can get a convenient method.

The content management unit 210 provides a web page corresponding to an address to a user terminal 400 connected to a predetermined address such as a uniform resource locator (URL) or an internet protocol (IP). Such a web page may be a view page that displays a plurality of posted contents in a unified form, a predetermined article (hereinafter, referred to as content) and a comment.

Also, the content management unit 210 can separately manage the content and the comment, and the location information data of each content and the comment can be included in the database 100 and recorded. Then, the content is provided to the user terminal 400 through a view page, so that the content and the comment of the content can be provided to the user terminal 400.

On the other hand, the database 100 includes a content database (not shown) in which contents provider membership number, content contents, location information previously registered by the content provider, and information on the error range S200 are stored. (Not shown) in which information on the user membership number, the comment content, the user error index, the trust index, and the comment display rank (S300) are stored in advance so as to be able to display and evaluate the comments using the comment database have. The database 100 in which such information is stored typically includes a predetermined computer-readable recording medium.

Such a recording medium includes all kinds of recording media in which programs and data are stored so that they can be read by a computer system. Examples of the recording medium include a ROM, a Random Access Memory, a CD (Compact Disk), a DVD (Digital Video Disk) -ROM, a magnetic tape, a floppy disk, The medium may be distributed over networked computer systems so that computer readable code can be stored and executed in a distributed manner.

The location information evaluation unit 220 evaluates the location of the data received from the user terminal 400 through the network 300 based on the location information. The latitude, longitude, and accuracy of the location information acquired by the geolocation API according to the present invention can be retrieved, and the error index and the confidence index of the corresponding comment can be calculated based on the latitude, longitude, and accuracy.

Here, the database 100 provides the positional information evaluation unit 220 with predetermined positional information, an error range, an error index, a confidence index, and the like recorded in the content database (not shown) and a comment database And can be recorded in the database 100 without passing through the ranking unit 230 according to the evaluation method of the position information evaluation unit 220. [

The ranking determining unit 230 may integrate the confidence index S300 of all the comments of each content calculated by the position information evaluating unit 220 to determine the entire comment ranking (order) according to the comment display order. The overall comment ranking can be configured such that the data is sorted in descending order, which is the earliest when the confidence index S300 is high. Although the ranking unit 230 is shown in the server 200 in FIG. 1, the server 200 may exclude the ranking unit 230 as needed.

Further, the entire comment ranking can be determined based on predetermined data concerning the evaluation method of the contents provider. The overall ranking may be determined by including a rating method when the location information is null in a content database (not shown) and a specific location rating method of the content provider.

Calculation and use of error index and confidence index

The reliability index can be calculated based on the location information (latitude, longitude, accuracy) as mentioned above. First, the reliability index is calculated before calculating the confidence index to exclude unreliable comments from the evaluation.

The low-reliability comment means that the distance between the position (S200) where the contents provider is registered in advance and the user position in which the comment is registered is longer than the predetermined distance. Here, the predetermined distance refers to the error range (S200) previously registered by the content provider.

The error index can be calculated by comparing the position information S200 of the content provider with the position information of the user. The error index has several purposes other than the purpose of excluding the low reliability comment from the evaluation.

If a user places a comment in a restaurant, the environmental factor (indoor location information accuracy is low in a high-rise building or a room where reflections and refractions are good due to characteristics of a satellite signal) If the error is large, it is difficult to evaluate the reliability of the comment. However, if the error index is compared with the error range (S200), such a problem can be minimized.

In addition, since the user location information means one point, an error range (S200) is referred to in order to evaluate a wide space. If the space such as a golf course, an amusement park, or a playground is wide, more accurate reliability evaluation can be performed by setting the error range (S200) of the contents provider.

According to an embodiment of the present invention, the calculation principle of the error index will be described in detail as follows. First, the error index is a unit of kilometers, which allows the content provider to know the distance difference between the location information (S200) predetermined by the content provider and the user location information.

The error index can be calculated as follows. For example, if you use the formula (sphere distance) to find the straight line distance between two points, you can see the straight line distance between two points. Since the position information includes latitude and longitude information, the position information may be configured to obtain a spherical distance. Thus, since the error index means the distance between two points, the error index increases as the distance increases.

The confidence index can be calculated based on the error index, the error range (S200), and the accuracy. The utilization of the error index may not be calculated because the above-mentioned unreliable comment is included in the comment when the user places the comment in the area other than the error range (S200).

On the other hand, the reliability index S300 can be utilized for a plurality of comments to calculate the overall reliability index. For example, if the distribution of the error varies depending on the specific position, the confidence index can be more accurately judged to the user. That is, if the distribution of the error index (S300) is utilized for a plurality of user comments in one content, the reliability index can be calculated based on a plurality of user error indices (S300) in a high-rise building or in a room.

In addition, the confidence index can be calculated with a more accurate confidence index with the accuracy acquired by the user terminal 400. [ The confidence index can make a more reliable comment evaluation method by making it difficult to manipulate the intentional comment rankings for the two reasons mentioned above.

The confidence index can be calculated as follows. For example, an average value and a standard deviation of an error index S300 included in a plurality of user comments are obtained. Then, a deviation between the average value and the user error index is obtained. The greater the deviation, the greater the distance from the average value, and thus the confidence index is lowered. Also, the reliability index can be calculated including the accuracy of the user location information according to the size of the standard deviation.

As described above, according to the embodiment of the present invention, it is difficult to intentionally manipulate the confidence index, thereby reducing publicity and slander. The error index S300 and the confidence index S300 can be calculated without directly recording the position information of the user in the database 100. [

In addition, if the above method is used, a reliable aspect can be evaluated based on whether a comment is posted at an actual visiting place.

Location information null Evaluation method

A method of evaluating a comment when the location information is null in a content database (not shown) storing information in a content provider including location information (S200) and an error range (S200) determined by the content provider will be described.

As described above, according to the present invention, an error index and a confidence index can not be calculated without recording predetermined positional information in a content database (not shown). Therefore, the error index and the confidence index are calculated by referring to the basic values. For example, the latitude and longitude default values can calculate the error and confidence indices with values of 37.246 and 127.556, respectively.

In summary, the error index can be calculated by substituting the above basic values. Since the error index does not refer to the error range (S200) unlike the above-mentioned contents, it is impossible to distinguish the low reliability indices. Therefore, the reliability index calculation is performed by including the error index standard deviation value in a plurality of comments.

Here, the standard deviation is a means for replacing the error range (S200), meaning that the standard deviation value is large, which means that it may be distributed far away from the average value and may be distributed evenly. The reliability index can be calculated.

How to evaluate a specific location

The specific location evaluation method generally follows the predetermined settings of the content provider and the person skilled in the art, and the predetermined setting of the content provider can be referred to a content database (not shown) as mentioned above.

FIG. 2 is a database relating to content provider information, and may be recorded including predetermined specific positional information and specific positional error range data. The specific location information may be recorded in advance with latitude and longitude information of the specific location. The specific position error range can be recorded in advance in the error range with respect to the specific position. In addition, since evaluation of a good user can be limited, a person skilled in the art can easily set the allowable range. And may be separately recorded in the database 100 as '/' symbols to evaluate a plurality of specific positions.

Here, the specific position information and the specific position error range have functions similar to the position information (S200) and the error range (S200) mentioned in the calculation and use of the error index and the confidence index , The error index and the confidence index are not operated if they exist within the position error range, and the error index and the confidence index can be calculated when the region is outside the error range.

Ranking comments

According to the present invention, the confidence index according to the present invention can be used for ranking the comments in the ranking unit 230. Ranking can also be used as a comment marking method.

First, the comment ranking (S300) may have the highest priority as the comment having the highest confidence index (S300). For example, if the confidence indexes (S300) are 156.25, 92.59, and 96.15, respectively, as shown in FIG. 3, a comment having a confidence index at 156.25 is ranked 1, a comment having a confidence index at 96.15 is ranked 2 (S300).

In addition, the comment ranking (S300) may be determined only in the value of the error index (S300), and the rank (S300) may be determined. If there is an error index (S300) value, it means that the comment is not a low-reliability comment. Therefore, the comment (S300) can be determined in the comment registration order only for the comment with the error index (S300). However, when the location information (S200) is null in the content database (not shown) linked to the content, the low reliability can not be distinguished only by the presence or absence of the error index. In this case, Follow.

Meanwhile, the user terminal 400 according to the present invention may be connected to the server 200 by any digital device capable of accessing the Internet through a wired or wireless network such as a personal computer, PDA, or PMP. Therefore, in the user terminal 400 in which the location information is not confirmed even if the user terminal 400 has the basic requirements described in the entire system configuration , the error index S300 and the confidence index S300 are null. In this case, The overall ranking (S300) can be determined in registration order. For example, the comments whose reliability indexes have been computed first are ranked in the order of higher confidence indexes, and then the comments for which the confidence indexes are not computed can be ranked in the order of registration.

As described above, according to the embodiment of the present invention, the reliability of the comment can be measured and the ranking can be determined through the user location information. As the user provides the comment input from the near range after using the restaurant service in the top rank, the user may increase the post immediately after using the service, which can improve the quality of the trust and quality of the comment.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. And falls within the scope of the invention.
