Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.

It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.

In order to ensure the authenticity of UGC content as much as possible, the embodiment of the specification provides a method for determining the authenticity of information, which can be applied to judging the authenticity of user-generated information, namely UGC content.

Fig. 1A is a flowchart of a method for determining authenticity of information provided by an exemplary embodiment. As shown in fig. 1A, the method may include the following processes:

in step 100, target positioning data corresponding to target information is obtained, where the target positioning data is used to characterize a user location where the target information is released.

In the present description embodiment, the user-generated UGC content may be referred to as target information, and the target information may be information associated with a point of interest (POI, point of Interest).

For example, if the POI is a restaurant, then the target information may be: and (5) evaluating information about the dishes of the restaurant.

For another example, if the POI is a park, the target information may be: comment information for the park.

For another example, if the POI is a scenic spot, the target information may be: photo information within the scenic spot.

The above is merely an example, and in summary, the target information may be some information related to a POI, such as some comment information on a POI as described above.

Wherein, the target positioning data of the target information can be a user position used for representing and issuing the target information. For example, the target location data corresponding to the target information may be the longitude and latitude of the location point of the user who publishes the information for a certain period of time before the information publishing time. For another example, the target positioning data corresponding to the target information may also be a certain piece of navigation positioning data before the information release time of the user who releases the information. For another example, the target information may be a picture, and then the target positioning data of the picture may be the longitude and latitude of the picture when the picture is taken, in which case, since the picture is usually taken by the user using the camera, the longitude and latitude of the picture when the picture is taken also represents the location of the user who issues the picture.

In step 102, the authenticity reference information of the target information is determined according to the association relationship between the target positioning data and the positioning data of the interest point.

In the method of the embodiment of the present disclosure, in order to verify the authenticity of the target information, it may be determined whether there is an association between the target positioning data corresponding to the target information and the positioning data of the POI, and the authenticity reference information of the target information may be determined according to the association relationship between the target positioning data of the target information and the positioning data of the POI.

Wherein, when determining the authenticity reference information of the target information according to the association relationship between the target positioning data corresponding to the target information and the positioning data of the POI, the method can be understood as follows: since the target information is information for the POI, taking the example that the target information is comment information for the POI, the user who publishes the target information really goes to the POI, and can only consider that the real probability of the target information for the POI published by the user is higher. Otherwise, if a user never goes through the POI, then there is a high probability that the information about the POI that the user published is not trusted. Therefore, the embodiment of the specification acquires the target positioning data of the target information, the target positioning data can represent the position of the user, and the travel behavior of the user can be reflected through the target positioning data representing the position of the user, so that whether the travel behavior of the user is associated with the position of the POI or not is judged, and whether the user really goes to the position of the POI or not is judged. If the judgment result is that the user position represented by the target positioning data of the target information is far away from the position of the POI represented by the positioning data of the POI, the user is likely to not go through the POI; otherwise, if it can be determined that the user has gone through the POI, then it can be determined that the target information for the POI published by the user is highly probable to be authentic.

Further, the authenticity reference information of the target information in the embodiments of the present specification refers to information that can be used as a measure of the authenticity of the target information. For example, if the target information is marked with an authenticity label for representing authenticity, the target information may be interpreted as having a high probability that the target information is authentic. For another example, some parameters may be used as the authenticity reference information, and by way of example, the distance between the longitude and latitude of the picture and the POI is used as the authenticity reference information, and the larger the distance, the lower the probability that the target information is authentic. Of course, the longitude and latitude parameters of the picture are only schematic, and are not limited to the above. In summary, the authenticity reference information may correspond to a factor that measures the authenticity of the information.

Furthermore, the method for determining the authenticity of information in the embodiment of the present disclosure provides a way to measure the authenticity of information based on the association relationship between the target positioning data of the target information and the positioning data of the POI, but the embodiment is not limited to the following two points:

1) The specific use and manner of use of the above-mentioned authenticity reference information are not limited:

for example, the authenticity reference information may be an evaluation result that gives only one of the authenticity of the target information.

For example, the authenticity reference information may be combined as one of the considerations, and then subjected to other data processing. Illustratively, when ordering and displaying a plurality of comment information of the POI, ordering and displaying the comment information with higher real probability that the authenticity reference information represents the target information; or, comment information with lower real probability of representing the target information by the authenticity reference information is not displayed.

For another example, when determining the authenticity of the target information, the authenticity reference information determined according to the method of the embodiment of the present disclosure may be used as one of the influencing factors, and the authenticity of the target information may be comprehensively determined by combining other various factors.

2) The output mode of the above-described authenticity reference information is not limited:

for example, when the authenticity reference information is a parameter, such as the distance between the longitude and latitude of the picture and the POI, the parameter itself may be directly used as the authenticity reference information; alternatively, the above parameters may be converted into another measurement factor to be output as the authenticity reference information.

For another example, the authenticity reference information may also be output by means of a tag. That is, the target information may be marked, and if an authenticity tab for characterizing authenticity is set to the target information, it is indicated that the target information is authentic. It is even possible to set a tag of the non-authentic information for the target information, indicating that the information is not authentic, which is also an authenticity reference information. That is, the authenticity reference information is information that measures the authenticity (or probability of authenticity) of the information.

In the following description of the embodiment, how to judge the authenticity of information will be described taking as an example the form of the authenticity reference information being a tag. Also, in the following description, description is mainly made with setting logic for characterizing an authenticity tag having authenticity, and if the authenticity tag is set for target information, it is indicated that the information is authentic. The specific determination mode may be: for target information aiming at the POI, if the distance between the position represented by the target positioning data of the target information and the position represented by the positioning data of the POI is within a preset distance range, setting an authenticity label for representing authenticity for the target information.

In the present embodiments, the authenticity labels may include a variety of types of labels, including but not limited to the following:

1) And the scene representation tag is used for representing that the picture in the target information is shot at the position of the POI on site.

The present embodiment is not limited to the specific name of the field characterization tag, for example, the tag may be named "field shot", or may be named "field", or may also be named "live shot", or the like. In summary, whatever the specific tag name, it may indicate that the picture was taken in the field at the location of the POI.

In the subsequent embodiments of the present specification, description will be given taking a label named "live shooting" as an example.

2) And the on-site meaning label is used for indicating that the user issues the target information at the position of the interest point.

Similarly, the present embodiment is not limited to the specific name of the on-site meaning tag, for example, the tag may be named "on-site issue", or may be named "on-site", or may also be named "real-time issue", or the like. In any case, whatever specific tag name is, it may indicate that the user publishes the target information at the location of the point of interest.

In the subsequent embodiments of the present specification, description will be given taking as an example a label named "field release".

3) And the resident characterization tag is used for indicating that the user resides at the position of the interest point before the target information is released.

Similarly, the present embodiment is not limited to the specific name of the resident characterization tag, for example, the tag may be named "post-resident issue", or may be named "once" or the like. In general, whatever specific tag name may be used, it may indicate that the user resides at the location of the point of interest prior to the release of the target information.

In the subsequent embodiments of the present specification, a label named "post-residence issue" will be described as an example.

4) And the navigation characterization tag is used for indicating that the user has the action of navigating to the interest point before issuing the target information.

Similarly, the present embodiment is not limited to the specific name of the resident token tag, for example, the tag name may be "post-navigation release", or may be named "once-navigated to here", or may also be named "navigation arrive", etc. In summary, whatever the specific tag name, it may represent that the user has an action to navigate to the point of interest before publishing the target information.

In the subsequent embodiments of the present specification, description will be given taking as an example a label named "post navigation release".

It will be appreciated that the authenticity labels are not limited to the examples described above, but may be other authenticity labels, such as post-consumer release. Regardless of the type of the authenticity tag, as long as the authenticity tag is applied to the target information, the target information may be represented as the authenticity information, but the authenticity information may be classified into a plurality of types, each of which corresponds to the above-mentioned authenticity tag.

The processing procedure of this information authenticity determination method will be described in detail below, wherein in the following description, how to label (i.e., set a label) target information will be described taking several kinds of authenticity labels as examples of the above. In addition, it should be noted that, the processing of the method for determining the authenticity of information in the embodiment of the present disclosure does not limit the processing time, for example, after the user submits the target information and before the target information is issued, the target information may be marked according to the method of the present disclosure and then issued. Or, the user may issue the target information first and then mark it according to the method of the present specification. The target information initially issued may have an initial tag, and the tag may be updated after the initial tag is found to be wrong according to the method of the present disclosure.

1) Setting of field characterization tags:

for example, taking the field characterization tag as "field shot" as an example, the field shot tag may be set for a picture. For example, if a picture is verified and found to be captured in the field at the location of the POI, a tag "field capture" may be set for the picture.

Referring to the illustration of fig. 1B, a "live shot" 12 has been marked in the picture 11. Specifically, it is assumed that the picture 11 is a snowman photographed at a bamboo park, and that the picture 11 is photographed by a user at the bamboo park site. The user publishes a rating for bamboo parks in a web page, and the rating information published by the user can be referred to as "target information" referring to the illustration of fig. 1C. In fig. 1C, the target information may include a plurality of pictures, or may include a text evaluation "bamboo park has been many times, landscape of park is beautiful … …". Of course, in other examples, only the "live-shot" tag of the present embodiment of the picture may be used as the target information, and the "live-shot" tag may correspond to a single picture, that is, it is specifically determined whether or not to set the live-shot tag for a certain picture. Further, if at least one picture among the pictures issued by the user is marked "live shot", the whole set label of the target information may also be set to "live shot", as in the label 13 shown in fig. 1C.

Fig. 2 is a flow chart of a method of determining authenticity of information provided by an exemplary embodiment for describing processing logic for whether a field characterization tag is set for a single picture. As shown in fig. 2, the method may include the following processes:

In step 200, the longitude and latitude of the picture at the time of picture shooting in the target information are obtained.

Wherein, the target information comprises: and (5) a picture.

In this step, the target positioning data during the image capturing may be longitude and latitude coordinates during the image capturing, which are called as image longitude and latitude. The longitude and latitude of the picture can be obtained by analyzing exif information serving as the picture attribute.

Since a picture is typically taken by a user, the target location data of the picture can also be used to characterize the location of the user who published the target information. For example, the user shoots a scenery in a bamboo park, and then the position of the user can be known according to the longitude and latitude of the scenery picture, namely, the user is in the bamboo park.

In step 202, if the distance between the longitude and latitude of the picture and the longitude and latitude of the POI is within the preset distance range, setting the authenticity tag of the picture as a field characterization tag, where the field characterization tag is used for indicating that the picture is shot at the position of the interest point on site.

For example, in the above example, the POI may be a bamboo park, and the positioning data of the POI may be the longitude and latitude of the bamboo park. In this step, the distance between the longitude and latitude of the picture and the longitude and latitude of the POI can be calculated, and whether the distance between the longitude and latitude of the picture and the longitude and latitude of the POI is within a preset distance range is judged. If the distance is within the preset distance range, the authenticity tag of the picture can be set as field shooting. For example, when the POI is a bamboo park, the corresponding preset distance range is 100 meters, and if the distance between the longitude and latitude of the picture and the longitude and latitude of the POI is within the range of 100 meters, the picture tag may be set as the field characterization tag. For example, the field characterization tag set in the present embodiment may be "field shooting".

In this embodiment, the preset distance range is different according to the category of the POI, for example, there may be multiple categories of POI, including but not limited to: scenic spots POIs, food POIs, hotel POIs, etc. Different classes of destination POIs may correspond to different preset distance ranges. The distance range is set properly, in practical implementation, the proper preset distance range can be determined on the basis of ensuring enough accuracy by evaluating the badcase rate of the pictures under different preset distance ranges. Wherein, the badcase rate can be understood as follows: if the longitude and latitude of the picture and the longitude and latitude distance of the POI are calculated, the picture is recalled, namely the picture is marked as being shot on site, but the picture is found to be not the picture shot on site through examination, and the picture is badcase.

As described above, in the present example, if the distance between the target positioning data of the picture and the positioning data of the POI is within the preset distance range, the picture can be regarded as being taken at the position of the POI, so the authenticity flag of the picture can be set as "live-shot". The tag is used for indicating that the picture is shot at the position of the POI on site.

The picture is marked with 'on-site shooting' under the condition that the distance between the target positioning data of the picture and the positioning data of the POI is in the preset distance range, so that the authenticity of the picture information is ensured through marking, and the picture is obtained through on-site shooting by the aid of an on-site shooting label. For example, in comment information about a bamboo park issued by a user in fig. 1B, through a set tag, other readers can know that a picture in the comment information is a picture taken by the user fengqingyang in the bamboo park.

As an inverse example: if a user shoots a landscape picture in a hundred-vac park, but issues a comment on a bamboo park, and when the background checks, the user finds that the longitude and latitude of the picture of the landscape picture are too far away from the positioning position of the bamboo park according to the judgment logic shown in fig. 2, and the position is beyond the preset distance range, the user can determine that the landscape picture is not shot in the bamboo park, and the user cannot mark the landscape picture with a scene shooting tag.

As can be seen from the example shown above, in this embodiment, through the field shooting of the logic marking shown in fig. 2, the reader of the information is helped to know the authenticity of the target information, especially to know whether the picture in the target information is obtained by field shooting at the position of the POI, which is helpful for the reader to obtain more authentic and credible information, so as to assist the reader in making a correct trip decision, for example, the reader can decide whether to play in bamboo parks according to the information.

In addition, the distance between the target positioning data of the picture and the positioning data of the POI calculated by the embodiment can also be used for reminding when uploading the picture shot off site. For example, if the user in the above example is operating to upload the landscape picture of the hundred-thousand park to the comment information of the bamboo park, if the longitude and latitude of the picture of the landscape picture is far away from the longitude and latitude coordinates of the bamboo park and exceeds the preset distance range, a similar prompt can be prompted to the user popup window in the process of uploading the landscape picture by the user, so as to prevent the user from uploading unreliable information. Even if the user ignores the prompt, the scenic picture of the Schwann park is still uploaded, and whether the target information is released can be determined according to the recorded popup window prompt during background auditing.

In view of the reasons of unstable GPS signals, equipment and shooting use software used by users, etc., the longitude and latitude data of the pictures can drift in the level of 10-100 meters or the positioning is lost, which can cause the pictures which are originally shot on site, but the pictures are not marked with labels shot on site, and the readers are influenced to obtain more real information. Based on this, the present description uses some way to make a picture marking call, i.e. some pictures that are truly taken at the POI site but not originally marked are retrieved and the site-taken label is re-marked.

Several ways of live picture recall are illustrated as follows:

the first, the supplementary recall mode of picture clustering:

this is applicable to the fact that part of pictures in the target information are marked, and the other part of pictures which are not marked can be recalled by using the method. For example, a picture that has been photographed by a marking site may be referred to as a first picture, a picture that has not been successfully marked may be referred to as a second picture, and a plurality of pictures may be included in one item of marking information, and at least one of the first picture and at least one of the second picture may be included in the plurality of pictures.

For example, referring to the illustration of fig. 3, the target information issued by the user includes 4 pictures, "picture 31, picture 32, picture 33 and picture 34", wherein 3 pictures have been labeled by the process shown in fig. 2, however, the picture 34 is not labeled due to drift of positioning or loss of positioning data. In this case, it is determined whether the picture 34 is a live picture or not by the recall method of the picture clustering described herein.

Specifically, the picture 31, the picture 32, and the picture 33 in the above example may be referred to as a first picture, and the picture 34 may be referred to as a second picture, as shown in fig. 3, which are included in the same target information. And, the distance between the target positioning data (such as longitude and latitude of the picture) and the positioning data (such as longitude and latitude of the POI) of the first picture when the first picture is shot is within a preset distance range, and the authenticity label of the first picture is set as field shooting.

For the second picture, i.e., picture 34, the distance between its target location data and the location data of the POI is outside the preset distance range and is therefore not marked. In this case, whether the attribute information of the second picture meets the picture clustering condition may be continuously determined, and if the attribute information of the second picture meets the picture clustering condition, the authenticity tag of the second picture may be set as field shooting. The picture clustering condition is used for indicating that the second picture and the first picture have at least partial association, that is, at least some commonality exists between the first picture and the second picture, and the pictures can be acquired together in a short time.

The image clustering condition may include, but is not limited to, the following conditions:

condition 1: the distance between the target positioning data and the positioning data of the POI when the second picture is shot is in a recall expansion range, the recall expansion range is larger than the preset distance range, and the recall expansion range is obtained by increasing a preset distance based on the preset distance range.

The fact that the recall range and the preset distance range are large means that, for example, when the first picture is marked, the preset distance range adopted is 50 meters, for example, the distance between the longitude and latitude of the picture 31 and the longitude and latitude of the POI bamboo park is within 50 meters, and then the authenticity label of the picture 31 is set as field shooting. For the second picture, i.e., picture 34, the recall range for the extension may be 100 meters, which is expanded compared to 50 meters, i.e., the recall range is obtained after adding a predetermined distance of "50 meters" to the 50 meters basis. Then, if the distance between the picture longitude and latitude of the picture 34 and the longitude and latitude of the POI bamboo park is within a range of 100 meters, the authenticity tag of the picture 34 may be set as live shooting.

It can be seen that when there are multiple pictures in the same target information, where some pictures have been marked as being shot in the field, the marking condition can be properly relaxed for another part of the pictures, because in the same target information, if some pictures have been marked as being shot in the field, the confidence that another part of the pictures that are not marked will be shot in the field will be improved, and it is likely to be shot in the field, but the pictures may not be marked due to drift of longitude and latitude data of the pictures, and the like.

As described above, in the present condition 1, the attribute information of the second picture according to the present condition is the picture longitude and latitude.

Condition 2: the time interval between the time of the taking of the second picture and the time of the taking of the at least one first picture is within an interval threshold. In this condition 2, the attribute information of the second picture according to the present invention is the photographing time of the picture.

The image attribute of the image recorded during shooting may further include shooting time, for example, the exif information may include shooting time. The shooting time is used to indicate when the picture was taken.

In this condition, if the time interval between the photographing time of the picture 34 and the photographing time of the first picture is within the interval threshold, the picture 34 may be marked for live photographing. For example, the interval threshold may be set to 20 seconds. Further, when there are a plurality of the first pictures, it may be determined that a time closest to the photographing time of the picture 34 among photographing times of the plurality of the first pictures is within the interval threshold.

For example: the shooting times of the picture 31, the picture 32 and the picture 33 are respectively "12:5:06 seconds, 12:5:20 seconds, 12:6:02 seconds", and the shooting time of the picture 34 is "12:6:12 seconds", and it is possible to determine that the time interval between the shooting time of the picture 33 and the shooting time of the picture 34 is "12:6:02 seconds and 12:6:12 seconds" is 10 seconds, and the 10 seconds are within the interval threshold value of 20 seconds, so that the picture 34 can be marked for live shooting.

Condition 3: the second picture acquisition equipment and the first picture acquisition equipment belong to the same equipment.

In this condition 3, the attribute information of the second picture according to this is the device information of the capturing device of the picture. For example, device information of the capture devices of the pictures 34 may be compared, and based on the device information, it is determined whether the capture device of the second picture is the same device as the capture device of the first picture. If the same device is used, the picture 34 may be considered to be taken on site.

As long as the second picture satisfies at least one of the conditions described above, it may be determined that the second picture is taken in the field at the location of the POI, and the in-field taking may be marked for the second picture. In practical implementation, the three conditions may be that when only one of the conditions is satisfied, the second picture is marked and shot on site; it is also possible to set the second picture to satisfy two or three conditions therein before setting the live photographing tag therefor.

As described above, the above-mentioned condition of clustering pictures means that the pictures are taken by a single piece, for example, the pictures are taken by the same device on the scene, or taken by the same time period, or taken by the same location area, and only some of the pictures are marked for various reasons, and for the remaining pictures, the above-mentioned conditions 1 to 3 are that the pictures are taken by finding the scene with unsuccessful marking by using the relevant characteristics of the pictures, for example, the same location area, the same time period, the same device, etc., and supplementing the pictures with the scene with unsuccessful marking. It will be appreciated that, particularly where applicable, at least one of the conditions may be set to be satisfied, for marking the picture.

By adopting the recall mode of the picture clustering, pictures which are truly shot on site but are not successfully marked for various reasons are replenished and marked on site shooting, so that real information is increased as much as possible, more credible information is provided for information readers, more real information which can be referred by the readers is provided, and more accurate trip decisions can be made by the readers.

Second, the recall mode of AOI buffer:

The AOI (Area Of Interest) has an Area range and is also a POI, but the POI is not a point, but an Area, and the AOI may be also referred to as an Interest plane. For example, the AOI may be a scenic spot, which is then regional in scope.

For this AOI type, the method adopted in the determination of the shooting at the marking site in the embodiment of the present specification may be: the vertical line is drawn to the edge of the area of the AOI at the position corresponding to the longitude and latitude of the picture when the picture is shot; and if the length of the vertical line is within the preset distance range, setting the authenticity label of the picture as field shooting.

For example: taking AOI as an example of a park, the park will have a boundary contour, i.e. the area edge of AOI. If one picture is the photographed picture of the park, acquiring longitude and latitude coordinates of the picture, and making a vertical line to the boundary contour line of the park from the position indicated by the longitude and latitude coordinates of the picture. The length of the perpendicular line can represent the distance between the longitude and latitude coordinates of the picture and the region edge of the AOI, and if the distance is within a preset distance range, the authenticity label of the picture can be set as field shooting.

Thirdly, the user positioning is used as a picture longitude and latitude recall mode:

because longitude and latitude data of pictures strongly depend on GPS signals and are possibly lost in various links such as user equipment, shooting lenses, picture repairing software, uploading modes and the like, the situation that some pictures lack longitude and latitude coordinates may exist. In this case, for a picture lacking longitude and latitude coordinates, the capturing time of the picture may be obtained by analyzing exif information, and a plurality of user positioning data of a user who captures the picture in a period corresponding to the capturing time may be obtained, where the positioning data may be the longitude and latitude of a user positioning point. The user positioning data is used as target positioning data of the picture. For example, assuming that the photographing time of a picture is 12 points 6 minutes, the photographing time corresponding period may be set to "11 points 55 minutes to 12 points 10 minutes", the longitudes and latitudes of a plurality of user positioning points within the period are acquired, and the number of these longitudes and latitudes may be a plurality.

Then, the minimum distance between the plurality of user positioning data and the positioning data of the POI in the period corresponding to the shooting time can be judged, and if the minimum distance is within the preset distance range, the authenticity label of the picture can be set as on-site shooting.

In this way, since the picture is generally taken by the user through a device such as a digital camera, when the latitude and longitude coordinates of the picture are lost, the latitude and longitude coordinates of the picture can be used as the latitude and longitude coordinates of the picture through the positioning data of the user. And if the positioning data of the user is satisfied within the preset distance range of the position of the POI, shooting the picture marking site. In this way, some pictures actually shot on site can be recalled as well, more trusted information is provided for the user to refer to, and correct decisions are assisted.

2) Setting of on-site meaning labels:

for example, the live meaning tag is exemplified by "live post" which is directed to the content type of the target information, but is not limited to the target information. For example, if a target message is marked for onsite publication, that means that the user is onsite publication at the location of the POI at the time the target message was published. Referring to the illustration of fig. 4, the target information issued by the user fengqingang is labeled with two authenticity tags "live shot, live evaluation", referring to two tags in the tag area 41 in fig. 4. The two tags mean that the target information is issued by the user fengqingyang at the site of the bamboo park, and that there is a picture taken at the site among pictures contained in the target information.

Fig. 5 is a flow chart of a method of determining authenticity of information provided by an exemplary embodiment for describing processing logic of whether to set a live meaning tag for target information. As shown in fig. 5, the method may include the following processes:

in step 500, acquiring longitude and latitude of a user positioning point corresponding to information release time of target information; the user is a user who publishes the target information.

The longitude and latitude of the user locating point corresponding to the information release time of the target information can be a time point of the information release time, can be a time point which is closer to the information release time, can also be a time period comprising the information release time, and is smaller in duration. For example, assuming that the information release time of the target information is "12 points on 11 months and 3 days 5 minutes", the longitude and latitude of the user positioning point in the period of "11 points on 11 months and 3 days 55 to 12 points and 10 minutes" may be acquired, and of course, the period is merely illustrative and not limited thereto.

In addition, in this step, besides the longitude and latitude of the user positioning point in the corresponding information release time obtained, other data may be obtained, for example, the signal strength of the WiFi signal connected to the user's device may also be obtained, so as to assist the signal strength to determine whether the user is on the POI site.

In step 502, if the distance between the longitude and latitude of the user positioning point and the longitude and latitude of the POI is within the preset distance range, setting the authenticity tag of the target information as a field meaning tag, where the field meaning tag is used for indicating that the user issues the target information at the position of the interest point.

In this embodiment, the on-site meaning tag is exemplified by "on-site release".

The following determination method is exemplified: for example, the number of longitudes and latitudes of the user positioning points obtained in the certain period may be plural, wherein most (the ratio may be set) of the distances between the longitudes and latitudes and the longitudes and latitudes of the POI are within a preset distance range, and the signal strength of the WiFi signal connected to the user equipment reaches a preset strength threshold value in the average value of the period, that is, the signal strength is also strong, so that it may be determined that, in the adjacent period corresponding to the information release time of the target information, the user is located at the POI site, and the authenticity tag of the target information may be set to be released on site. Of course, in other judging modes, the longitude and latitude of the user positioning point at the information release time point can be obtained, if the longitude and latitude are at the position of the POI, the user can be determined to be in the site of the POI, and the target information can be marked and released in the site.

In addition, other judging modes may be adopted, for example, when judging whether the distance between the longitude and latitude of the locating point of the user and the longitude and latitude of the POI is within a preset distance range according to the longitude and latitude of the locating point of the user, the method may be that the central point of the longitude and latitude of a plurality of locating points of the user in the period is obtained, and if the distance between the central point and the POI is within the preset distance range, the user is determined to be on the spot of the POI.

In order to make it easier for the user to understand the meaning of each authenticity tab set to the target information, it is also possible to set: when a click selection of an authenticity tab is detected, a description about the authenticity tab is popped up. For example, taking fig. 4 as an example, if the user clicks "release on site", a prompt message "the message is a message released on site in a bamboo park" may be popped up.

In addition, in any embodiment of the present disclosure, when data such as positioning data of a user is used, the data may be acquired after authorization approval of the user is obtained in advance.

3) Setting of resident characterization tags:

for example, resident characterization tags mean that the user who published the target information resides at the location of the POI before the target information is published. For example, taking the example that the POI is a mall, if the evaluation information (i.e., the target information) about the mall issued by the user marks "post-residence issue", that is, the user does go through the mall before issuing the target information.

For example, the user fengqingang issues a piece of target information, and the target information has no picture and is market evaluation information in pure text. And, the target information may be marked "post-residency release" in the tag area, meaning that the user fengqingyang was truly resident in the hundred-venues before releasing the target information, and not never had gone to the hundred-venues. Therefore, according to the label released after residence, the label information can be determined to have higher credibility, belongs to real information and can be referred by readers of the information.

FIG. 6 is a flowchart of a method for determining authenticity of information describing whether a resident characterization tag is set for target information, provided in an exemplary embodiment. As shown in fig. 6, the method may include the following processes:

in step 600, user positioning data in a time period before the information release time of the target information is acquired, wherein the user positioning data is a positioning point cluster comprising a plurality of positioning points; the user is a user who publishes the target information.

For example, assuming that the information distribution time of the target information is "12 points on 11 months 3 minutes" 5 minutes, the longitude and latitude coordinates of the user who distributes the target information in the period of 10 points 50 minutes to 11 points 30 minutes on 11 months 3 minutes are acquired, and these longitude and latitude coordinates constitute a localization point cluster. Referring to the illustration of fig. 7, fig. 7 illustrates one anchor point cluster, and may be an anchor point illustrating a portion thereof in the anchor point cluster.

In step 602, if the distance between the characterizing position of the locating point cluster and the locating data of the POI is within a preset distance range, and the duration of a plurality of locating points in the locating point cluster is longer than a preset duration, setting the authenticity tag of the target information as a resident characterizing tag, where the resident characterizing tag is used for indicating that the user resides at the position of the interest point before issuing the target information.

For example, the resident token tag may be "post-resident post-release".

In this step, when determining whether the distance between the characterization position of the anchor point cluster and the positioning data of the POI (the POI is a mall) is within the preset distance range, the center position of the anchor point cluster may be obtained, for example, the center position 71 shown in fig. 7. It is assumed that the distance between the center position 71 and the position of the POI is within a preset distance range.

In addition, it may also be determined whether the duration of a plurality of anchor points in the anchor point cluster is longer than a preset duration, for example, in the anchor point cluster shown in fig. 7, each anchor point has a corresponding time, that is, a time when the user is at the location of the anchor point. And finding the earliest time and the latest time in the anchor point cluster, and calculating the duration according to the earliest time and the latest time. For example, the earliest time in a anchor point cluster is 10 points 50 minutes, the latest time is 11 points 30 minutes, and the duration is 40 minutes. The duration has been greater than the preset duration for 20 minutes.

If the distance between the characterization position of the positioning point cluster and the positioning data of the POI is within the preset distance range and the duration time of a plurality of positioning points in the positioning point cluster is longer than the preset duration time, the user is indicated to reside at the position of the POI for a certain duration time, the reliability of the issued target information about the POI is higher, and the authenticity label of the target information can be set to be issued after the user resides.

In this example, according to the location information of the user represented by the target location data, the association relationship between the location information of the user and the location data of the POI may be determined, where the user resides at the location of the POI, so that the authenticity label corresponding to the association relationship is set to be issued after residing. Through the authenticity tag, a reader of the target information can know that the user who issues the information does go through the POI, and the information is more reliable.

4) Setting a navigation characterization tag:

the navigation characterization tag means that a user who issues target information has an action of navigating to a POI before issuing the target information. For example, the target information posted by the user is a comment on the garden, and the user has the behavior of navigating to the garden before, and then the target information can be marked with the mark of post-navigation posting.

FIG. 8 is a flowchart of a method for determining information authenticity describing processing logic for whether a navigation characterization tag is set for target information, in accordance with an exemplary embodiment. As shown in fig. 8, the method may include the following processes:

in step 800, navigation data of a user in a history period before an information release time of target information is acquired; the user is a user who publishes the target information.

For example, assuming that the information distribution time of the target information is "12 th 5 th of 3 th day of 11 months", the history period before the information distribution time may be within 2 months before the information distribution time. Illustratively, in this step, user navigation data within 2 months before the time of information distribution of the target information may be acquired.

In step 802, if the navigation terminal of the navigation data is a sub-point of the POI, or the navigation terminal is within the area corresponding to the POI, the authenticity tag of the target information is set as a navigation characterization tag, where the navigation characterization tag is used to indicate that the user has a behavior of navigating to the point of interest before issuing the target information.

For example, the navigation characterization tag may be "post-navigation post-release".

In this step, the determination may be made according to the navigation data of the user, where the navigation data generally includes a starting point and an ending point of navigation, and if the ending point of navigation is a sub-point of the POI or the ending point of navigation is in the area corresponding to the POI, the authenticity tag of the target information may be set to be issued after navigation.

Specifically, the navigation data may include various types of navigation data such as car guide data, public travel and riding data, and the like. The sub-point may be a point subordinate to the POI. For example, if the POI is a park, a park entrance such as a north door or a south door of the park may be used as a child point of the park. For another example, if the POI is an office building "zijin building", then both building No. 1 and building No. 2 of the zijin building may be referred to as sub-points of the POI, respectively. The area range corresponding to the POI at the navigation terminal point may be, for example, that the POI is assumed to be a scenic spot, and the navigation terminal point is a hotel in the scenic spot, and the location of the hotel is located in the area range of the scenic spot.

If the navigation terminal point of the user is the sub-point or the navigation terminal point is in the area range of the POI, the user can be considered to navigate to the POI, and the target information can be marked with post-navigation release. In addition, when acquiring navigation data of a user, in order to ensure reliability of the navigation data, screening may be generally performed according to a navigation duration and a navigation distance, for example, data in which a navigation record is greater than 3 minutes or a navigation distance is greater than 100 meters may be selected.

Further, in addition to the above-described example authenticity tags, other authenticity tags may be provided. For example, a consumption record of a user at a POI may be obtained, and a "post-consumption release" may be marked for target information for the POI based on the consumption record. For another example, the user may be guided to upload a consumption certificate such as a shopping receipt, and the target information issued by the user may be marked with "submit consumption certificate" accordingly. Other examples are not described in detail.

It should be further noted that, in practical implementation, the information according to which the tag is set to the target information may be combined with other types of information besides the target positioning data of the target information mentioned in the method described in the embodiment of the present specification. For example, the reliability of the target information can be comprehensively judged by referring to the credit history of the user who issues the target information. The embodiment of the present specification is not limited thereto, as long as the target positioning data corresponding to the target information of the present specification is incorporated in the process of tag setting, that is, within the scope of protection of the present application.

According to the method for determining the information authenticity, the credibility of the target information of the related POI is determined by comparing the relation between the target positioning data of the publisher of the target information and the positioning data of the POI, the credibility of the target information is guaranteed through the label, the true and reliable information is screened out as far as possible for reference of readers, and therefore the readers of the information can make correct travel decisions according to more reliable information, and user experience is improved.
