FIG. 3 is a flowchart illustrating an embodiment of forming user preferences in a method for recommending location-based digital content.

According to one embodiment, in step S301, the server system collects user browsing data through a browsing program executed in a computer device of each user end, wherein the characteristics of the data are related to the geographical location. For example, when the user operates the mobile device, wherein a browsing program provided by the system is executed, and the user arrives at a location, the browsing program is operated to report or record the videos, sounds, images or texts generated from the scenery within the geographic scope, the server system is connected and the generated contents are uploaded to the server system, the metadata (metadata) in the data already records the geographic information for generating the contents, including the identification data (obtained when the user logs in the system), in step S303, the uploaded contents can be analyzed in the server system to form the personalized data suitable for the user, and the personalized data can be stored in the database of the server system.

The servo system collects the activity data of the user on the network through a software program executed on the user end computer device in addition to establishing a database of the suitable personalized content (S305), the servo system can form suitable personalized data for the user according to the geographic information in the various activity data (S305), and then can learn the geographic related data characteristics and the weights (weights) of the various data characteristics by a machine learning algorithm (machine learning algorithm), and form a suitable personalized preference model describing the user 'S preference (S307) or form suitable personalized user preference data combined with some characteristic information (S), thereby obtaining one or more suitable personalized contents corresponding to the user' S preference (S). It is worth mentioning that different weights can be set according to the relevance of the data features obtained through machine learning, a higher weight can be given to the data features with high relevance, and a lower weight can be given to the data features with low relevance, so that the preference of the user can be described more accurately.

According to the embodiment, the activity data of the user on the network collected by the servo system through the user-side computer device can include the activity of the user on various social media, the search record, the contents of concern and browsing (including the theme tag of each browsing content), and the time information of various activities. For example, the browsing history may be a cookie, a copy and a history of the user browsing the web page through a web browser, activities in social media such as recording a card, searching for a record, agreeing to, sharing, tracking objects and responding to information, etc., which may also have a record related to a geographical location in some cases, and the record related to the geographical location refers to various behaviors related to a specific geographical and multimedia content related to the geographical location. Furthermore, when the user preference degree is judged, the characteristics of the user, such as time and period spent on browsing the content, frequency and length of browsing the related content, whether the content is shared by people and the like, and even the content produced by the user can be judged. This information can be used as the basis for the server system to build an adaptive personalized preference model or related database, and can be used to perform a preference ranking when the server system provides the user with a plurality of adaptive personalized contents.

According to one embodiment, the server system provides a browsing program executed in the user-side computer device to provide the user with a way to browse the contents on the map by operating the electronic map, each of the contents is linked to a specific geographic location, and during browsing, the server system also obtains browsing records of the user, such as movies, sounds, images or texts, the generated records include user identification data (user ID), geographic location or range (latitude and longitude), browsing contents and activities (e.g., favoring, collecting, sharing, etc.), and tags (tags) and time of the contents themselves, which can be the learning data of the learning algorithm, so as to form the basis of the preference of the user.

In another embodiment, the browsing program provided by the server system may be a user interface for providing a user to browse contents, such as a web browser, and when the user operates the browsing program to browse various contents, the contents will also be marked with geographically related information, including browsing records of the user, which also becomes the basis for the learning algorithm to learn the user's preference.

When the analysis of the user's preference is completed, the personalized preference model and the database are established, and then the purpose of recommending the personalized digital content can be achieved, the flow of the related method embodiment can refer to fig. 4.

The user can operate a graphical user interface with an electronic map as a background in a browsing program to browse information presented on the map, or a user interface with a non-electronic map as a background to browse contents containing position information (such as geographic information), wherein the display is linked to a movie, sound, image or text link information, or an image representing the user, so that the user can click. The content linked by the formed linking information is the personalized content. Specifically, in this case, the browsing program may generate location information according to the geographical location of the browsing, for example, a map of a range is displayed by the browsing program with an electronic map as a background, and the location information is the longitude and latitude of the central location of the range, and is transmitted to the servo system (step S401).

In the servo system, a position range (a geographical range is a map) can be determined according to the received position information (step S403). According to one embodiment, when the user browses to a specific geographic location by operating a browsing program in the context of an electronic map, the browsing program can transmit the obtained geographic location or its range to the server system, and query the database, so that the system can provide location-adaptive digital content within the location range, which can be location-adaptive and personalized digital content if referring to the personalized features. In another embodiment, the browsing program can be a general video or text browser, however, the geographic location can still be determined from the browsing content, such as the geographic information in the metadata of various contents, and similarly, the server system can obtain the location information of these contents from the browsing program, thereby providing the personalized and proper content. In another embodiment, when the computer device operated by the user is a mobile device, the browsing program can obtain the location information provided by the sensor (GPS sensor) or the wireless network signal in the mobile device at any time, and then transmit the location information to the server system, so that the server system can provide the personalized content according to the location of the mobile device.

In one usage scenario, the user executes the software program on his/her computer device, and the server system is connected to the server system, and can obtain a browsing scope presented by the computer device operated by the user in addition to the user identification data (logged into the system) through the browsing program to determine the geographic scope, which will affect the personalized content provided by the server system, because the user's preferences with respect to different sized geographic scopes will vary, and the amount of content provided to the user may need to be weighed due to display limitations (e.g., device screen size, display resolution, etc.).

Then, according to the obtained information, the server system mainly queries the database according to the geographical range and the identification data (step S405). Still further, the content in the database includes videos, sounds, images or texts related to geographical locations uploaded by a plurality of users using the computer device for reporting or recording, and the correlation between each digital content, the corresponding location information, the user identification data and the subject label of each digital content is established in the servo system. The database is queried according to the location information generated by the browsing program executed in the user device, so as to obtain the digital content associated with the location (or with personal preference), and obtain the related subject label accordingly (step S407). In one embodiment, in the server system, a personalized feature is obtained according to the user identification data of the browsing program, so as to filter out one or more suitable digital contents within the location range according to the personalized feature, and correspondingly obtain one or more suitable linkage maps displayed in the browsing program, besides marking the linkage maps on the electronic map, the server system also ranks the subject tags of the obtained digital contents (step S409), obtains one or more previous subject tags, and transmits the digital contents, the linkage maps and the subject tags to the user device (step S411). Finally, the link of the theme label transmitted by the servo system is displayed through the browsing program, and further, the digital content recommended by the servo system can be prompted through the browsing program, the display mode is not limited to a specific mode, for example, a connection thumbnail of the locality of the corresponding digital content can be marked on the electronic map as shown in fig. 5 (step S413).

In a further embodiment, as shown in the step S407, when determining the location range according to the location information generated by the user device, in addition to querying the database to obtain one or more suitable digital contents within the location range, the servo system may further consider a larger location range exceeding the location range, so as to query the database according to the larger location range, so as to further expand the calculation of the recommended subject label to a wider location range based on the user location information. The display servo system of the embodiment can provide more various recommended subject labels according to the user preference and the recommendation mechanism of the system.

Thus, according to one embodiment, when the user operates the browsing program to browse a specific geographic location, the server system can continuously analyze and learn new browsing records in addition to collecting the browsing records of the user, i.e. the browsing records of the user are continuously collected by the server system for learning and updating the personalized preference model. The server system can continue to provide personalized content, including various video and audio content, and commercial information (e.g., advertisement). That is, the method can recommend corresponding information according to the preference of each person (user) in a certain area, and the preference of each person in each area has personalized characteristics, which are not all the same.

FIG. 5 is a schematic diagram of an exemplary homepage of a software program for implementing the method for recommending location-based digital content, wherein a browser program executing on the user device initiates a graphical user interface in the context of an electronic map 510, the browser program provides the user device with access to a social services server system, and the user can browse the location-based digital content in a location range according to the current location or a selected location range by using the graphical user interface.

As described in the above embodiments, when the user starts the browsing procedure, the servo system will obtain the current position of the user, so as to provide an image of a home page 50, wherein the electronic map 510 can be a background image, the electronic map 510 can be a geographic map, a scenic spot, a street, etc. in a geographic area, and a personal page link thumbnail 504 is provided on the image, which can be used to browse the personal settings of the user and the related records of using social media; a search pattern 505 for searching digital contents is provided, and a keyword of contents to be searched can be input after the function of the search pattern 505 is clicked; the fast switch function 507 provides several fast buttons that can fast enter specific functions, for example, when the user browses to other locations, the user can fast return to the home page 50, and can also fast enter a function page for uploading digital content, and browse social media interactive content; a positioning pattern 508 is also provided to allow the user to quickly return to the location range (or geographic range) associated with the current location.

The home page 50 includes a plurality of linked thumbnails 511,513,515 (in this example, the number, size and screen during actual operation are not limited to this illustration), wherein each linked thumbnail 511,513,515 displayed on the graphical user interface is a representative image of a user linked to the digital content, the representative image is not limited to static graphics, but may be dynamic graphics, and text link information 512, 514, 516 (in 512, 514, 516) may be added, and the text link information 512, 514, 516 may make the user quickly know the content linked by the linked thumbnails. These contact maps 511,513,515 may be links of digital contents recommended by the server system to the user for browsing, wherein the server system may cover the most popular contacts in the digital contents in the geographic area according to the home page 50, or recommend digital contents by learning the personalized features of the user.

Specifically, according to the above-mentioned flow embodiment, when the servo system determines the corresponding position range according to the position information transmitted by the user device through the browsing program, and according to the range that can be displayed by the user device (e.g. according to the resolution of the display), so as to provide the initial home page 50, then the servo system can provide the corresponding frame according to the user operation, such as zooming in (zoom out) or dragging up, down, left, right (drag) the user interface to obtain the range to be browsed, and the browsing program will provide the corresponding frame, and the servo system will continue to calculate the theme label to be provided to the user according to the theme label of the digital content in the position range, as shown in this figure, the connection point displayed on the browsing program is as the multiple theme label links 501, 502, 503 marked on the electronic map 510, as shown in the example shown in the figure: # hashtag1, # hashtag2, and # hashtag 3. It should be noted that, in one embodiment, when the servo system recommends the corresponding digital content through the theme tag, the link thumbnail 511,513,515 is not necessarily displayed on the home page 50, but only the theme tag is provided according to the location range browsed by the user operating the browsing program.

The theme volume labels provided by the servo system can be the first few theme volume labels ranked according to specific conditions according to the embodiment shown in fig. 4, for example, the popular theme volume labels are obtained from the statistics of the digital contents covered in the first coordinate range and become the theme volume labels recommended to the user; the servo system provides the hot theme volume label, the theme volume label can also be a link of a point of interest (POI), and the POI recommended by the servo system can be determined according to the digital content uploaded by the user at a certain place, so that the servo system can recommend the relevant hot POI link according to the information. In another embodiment, in addition to the above method, a theme tag recommended to the user can be generated by comparing features learned from the user's preferences. Related embodiments reference may be made to a flowchart of an embodiment of playing digital content in a method of recommending location-based digital content shown in fig. 6.

After the servo system recommends one or more theme labels of the user through the browsing program according to the method described in the embodiments of fig. 4 and 5, the user may select one of the one or more theme label links 501, 502, 503, and the subsequent action is as the embodiment of the flow shown in fig. 6, the servo system receives a theme label link signal generated by the user device (step S601), the program running in the servo system queries the database according to the theme label selected by the user (step S603) to obtain the digital content corresponding to the theme label (step S605), and ranks (rankings) the obtained digital content according to the evaluation of each digital content (step S607).

According to an embodiment, the plurality of topic tags provided to the user device are ranked by a ranking to obtain one or more topic tags that are ranked first, i.e. a link to the one or more topic tags is displayed on the user interface, wherein the ranking of the plurality of topic tags obtained by the servo query is based on one or any combination of the number of digital contents, the number of followers, the number of plays, the rating and the creation time associated with each topic tag.

Then, a preview page initiated by the browser in the user device displays a preview image of the digital content corresponding to the theme tag (step S609). The preview page can be illustrated with reference to the digital content preview page shown in fig. 7, in which a digital content preview page 70 is displayed, in which a thumbnail image 701 and a theme tag 703 are displayed as an example, and a plurality of query preview images 705-714 are displayed, each of the preview images 705-714 is a link point of the complete digital content.

Further, when the preview images of the digital contents associated with the selected theme tag are displayed on the digital content preview page, the corresponding preview images may determine the display order of the preview images according to one of the distance, the matching degree of the activity data and the personalized features, an arbitrary combination thereof, or a weight distribution thereof. According to the above embodiment, when the servo system provides the preview images 705-714 of the plurality of digital contents through the digital content preview page 70, wherein the plurality of preview images 705-714 can be sorted according to several pointers, for example, the distance between the position information associated with the digital contents and the position information generated by the user device can be sorted according to the distance after the preview image with the highest priority from the nearest one; the ranking may also be based on activity data (e.g., time) of the user associated with the digital content to be previewed in the social media, for example, the user may have activity (e.g., like approval, sharing, or leaving a message) in the last period of time or have a high number of activities as a priority; the order of the digital contents to be recommended can also be arranged according to the interest characteristics of the user learned by the servo system, and the closest characteristic is to display the preview image preferentially. Furthermore, the above-mentioned distance, activity data and user interest are sorted according to the display order of the preview images 705-714, which can be assigned with a weight.

Then, the user can select to view one of the digital contents from the preview images 705-714, and the servo system receives a digital content selection and plays a digital content playing page initiated by the browsing procedure (step S611), as shown in the embodiment of the digital content playing page shown in fig. 8. FIG. 8 shows a digital content playback page 80 showing the digital content being played, along with other information such as user thumbnails 801 and other user interaction information 803 associated with the digital content.

According to the embodiment, the user device receives a plurality of theme volume labels provided by the servo system through a browsing program executed on the user device, wherein the theme volume labels are mainly descriptions marked when each digital content is created and uploaded to the servo system, or descriptions marked by the servo system actively according to digital content features, and further, the theme volume labels can be marked with a specific geographic location, such as a scenic spot, a landmark and the like.

In general, the servo system continuously obtains the position information from the user device and the position range covered by the user interface, so that when the position information changes, such as the position information of the user device changes, or the corresponding frame generated changes are provided according to the user operation, such as zooming in, zooming out, dragging up, down, left, and right, to obtain the position range to be browsed, a new position range is determined again, and the database is queried again to obtain updated one or more locality digital contents, corresponding one or more locality linked thumbnails, and associated one or more theme labels, so as to update the links of the one or more theme labels displayed on the user interface. Furthermore, the server system continuously collects and learns the records of various digital contents browsed by the user through the browsing program during operation, continuously analyzes and learns new browsing records, establishes and updates a personalized preference model describing the personalized features, and provides one or more theme labels to the user device in a personalized and suitable manner according to the personalized preference model.

For example, when the servo system obtains the first position information generated by the user device through the browsing program, the first position information may be the current position of the user or the information of the position range browsed by operating the user device, so that the first position information is associated with a first coordinate range. The servo system then queries the database according to the location information to obtain one or more proper digital contents associated with the first coordinate range, and obtains one or more theme tags of each proper digital content according to the associated theme tags recorded in the database, and then forms the theme tag links 501, 502, 503 shown in the figure of fig. 5. When the user operates the user device to change the position or change the position range to be browsed, the servo system receives second position information different from the first position information from the browsing program, and similarly, the second position information is associated with a second coordinate range, and at the moment, the digital content corresponding to the second coordinate range can be calculated again, and the theme volume label recommended to the user can be regenerated. When the user repeatedly adjusts the position range, the servo system also calculates the new theme label synchronously.

However, in one embodiment, the server system may also provide a method for saving computing resources, such as calculating a difference range between the second coordinate range and the first coordinate range, calculating the digital content and the theme tag only for the difference range, and combining the calculated difference range to generate a new theme tag recommended to the user, or omitting the calculation if the difference range does not reach a range T . Fig. 9 and 10 provide another embodiment.

Referring to fig. 10, a flowchart of an embodiment of forming a recommended theme tag according to fig. 9 can be seen, in which the map is divided into a plurality of blocks (step S901), wherein the blocks are divided into a plurality of blocks (step S1-M24) according to the computing power of the server system and the user' S habit of operating the browsing program (not necessarily rectangular). Next, when the servo system receives the digital content and the corresponding theme tag uploaded by each user at a certain position around the world or region (step S903), a block to which the user belongs can be determined according to the position information, and the block connected with the theme tag is marked in the database by an index (step S905).

Then, when the servo system receives the location information uploaded by each end user device through the browsing program, one or more blocks covered within the corresponding coordinate range can be obtained by querying the database (step S907), one or more covered local digital contents and corresponding theme labels can be obtained from the covered one or more blocks (step S909), the theme labels can meet the relevant conditions described in the above embodiment, and then one or more theme labels are provided after ranking (step S911). In the servo system, a personalized feature can be obtained according to the user identification data of the browsing program, one or more local digital contents in the position range can be screened out according to the personalized feature, and one or more local connection contracted drawings displayed in the browsing program can be correspondingly obtained.

Compared with the method that the servo system inquires the covered digital content and calculates the recommended subject label according to the position range each time, the method of the flow display can save the computing resource. It is noted that, in addition to the above-mentioned popularity, timeliness, and user personalization features, the subject label recommended to the user by calculation in the servo system can be actively provided by the servo system, such as a region close to the user's location, an adjacent region, a subject label with a larger range than the region under browsing, or a specific subject label with season, holiday, and commercial advertisement related features. Furthermore, in one of the above embodiments, when the system recommends the theme volume corresponding to the location range according to the location of the user, the theme volume beyond the location range may be provided for a specific purpose, for example, the system may recommend the user to know more peripheral geographical ranges according to the preference of the user, and expand the recommended theme volume to other areas centering on the current location, for example, when the user is browsing a geographical range mainly in the New York (New York) area, the servo system calculates the recommended theme volume, and may expand to adjacent areas such as Philadelphia and Washington DC, so that the range of the calculated theme volume may cover a wider geographical range.

In summary, according to the method and system for recommending location-based digital content described in the above embodiments, a social media service is provided, which allows a user to conveniently obtain a location-related recommended topic tag, allows the user to quickly link to various recommended digital contents through the system-recommended topic tag, and can screen out location-based digital contents within a specific location range according to personalized features, and allows the user to conveniently view videos, sounds, images or texts reported or recorded by multiple users and uploaded in association with the location, and when a servo system continuously collects and learns the records of various digital contents browsed by the user through a browsing program, a location-based personalized preference model describing personalized features can be established and updated to recommend location-based and personalized preferred digital contents.

The disclosure is only a preferred embodiment of the invention and should not be taken as limiting the scope of the invention, which is defined by the appended claims.
