Description

[Technical Field]

[0001] The present disclosure relates to a method and system for rating content via an instant messaging application, and more particularly, to a method and system for sharing a screen associated with a user account in a chat room in which the user account is included in an instant messaging application, and receiving a rating for at least one piece of content included in the shared screen from at least one user account included in the chat room. [Background technology]

[0002] With the spread of mobile devices such as smartphones and the development of the Internet, instant messaging applications are widely used, and users of such applications can naturally communicate with each other and share opinions in their daily lives. These users may be faced with a crossroads of choices in various areas of their daily lives and may want to hear the opinions of their acquaintances about their choice in order to make a rational choice. Thus, users can request and hear the evaluations and opinions of other users or acquaintances about the choice they are interested in through instant messaging applications.

[0003] In conventional instant messaging applications, in order for a user in a chat room to share content that they wish to rate, they must leave the chat room, operate another application or messaging application, and share the content in the chat room in the form of an image or file. This requires the user to access the content to be rated from outside the chat room, share it in the chat room, and then share the new content from outside the chat room again to add the content to be rated, which is inconvenient. In such an environment, the number of pieces of content to be rated may be limited. Furthermore, since users of such instant messaging applications simply communicate their opinions on the shared content via text or voice, there are limitations to the effective communication of opinions between multiple users. Furthermore, in order to use a voting list generation service provided by conventional instant messaging applications, users must manually enter the voting list, which is inconvenient. Therefore, when a user wishes to rate content of interest through a service provided by a conventional instant messaging application, the more people and content in the chat room there are, the more inconvenient it becomes to use the service.

[0060] FIG. 3 is a block diagram illustrating the internal configuration of a user terminal (220) and a content rating system (200) according to an embodiment of the present disclosure. The user terminal (220) may refer to any computing device capable of executing an instant messaging application and capable of wired / wireless communication, such as the mobile phone terminal (220_1), tablet terminal (220_2), or PC terminal (220_3) of FIG. 2. As illustrated, the user terminal (220) may include a memory (312), a processor (314), a communication module (316), and an input / output interface (318). Similarly, the content rating system (200) may include a memory (332), a processor (334), a communication module (336), and an input / output interface (338). As illustrated in FIG. 3, the user terminal (220) and the content rating system (200) may be configured to communicate information and / or data over the network (210) using their respective communication modules (316, 336). The input / output device (320) may also be configured to input information and / or data to the user terminal (220) via the input / output interface (318) and to output information and / or data generated by the user terminal (220).

[0061] The memory (312, 332) may include any non-transitory computer-readable recording medium. According to one embodiment, the memory (312, 332) may include a non-volatile permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), a disk drive, a solid state drive (SSD), or a flash memory. As another example, a non-volatile mass storage device such as a ROM, an SSD, a flash memory, or a disk drive may be included in the user terminal (220) or the content rating system (200) as a separate permanent storage device distinct from the memory. The memory (312, 332) may also store an operating system and at least one program code (e.g., code for an instant messaging application installed and running on the user terminal (220)).

[0062] These software components may be loaded from a computer-readable recording medium separate from the memory (312, 332). Such separate computer-readable recording medium may include a recording medium directly connectable to the user terminal (220) and the content rating system (200), such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. As another example, the software components may be loaded into the memory (312, 332) via a communication module rather than a computer-readable recording medium. For example, at least one program may be loaded into the memory (312, 332) based on a computer program (e.g., an application providing an instant messaging application service) that is installed by a file provided over the network (210) by a developer or a file distribution system that distributes application installation files.

[0063] The processors (314, 334) may be configured to process computer program instructions by performing basic arithmetic, logic, and input / output operations. The instructions may be provided to the processors (314, 334) by the memory (312, 332) or the communication modules (316, 336). For example, the processors (314, 334) may be configured to execute received instructions based on program code stored in a storage device, such as the memory (312, 332).

[0064] The communication modules (316, 336) may provide a configuration or function for the user terminal (220) and the content rating system (200) to communicate with each other via the network (210), and may provide a configuration or function for the user terminal (220) and / or the content rating system (200) to communicate with other user terminals or other systems (e.g., a separate cloud system, a separate screen sharing support system, a content information providing system, etc.). For example, a request (e.g., a content selection request, a content rating request) generated by the processor (314) of the user terminal (220) based on program code stored in a storage device such as the memory (312) may be transmitted to the content rating system (200) via the network (210) under the control of the communication module (316). Conversely, control signals or commands provided under the control of the processor 334 of the content rating system 200 may be received by the user terminal 220 via the communication module 316 of the user terminal 220 via the communication module 336 and the network 210. For example, the user terminal 220 may receive at least one selected piece of content and / or information related to the at least one selected piece of content from the content rating system 200 via the communication module 316.

[0065] The input / output interface (318) may be a means for interfacing with the input / output device (320).

In one embodiment, information related to the at least one content may be output together with the at least one selected content in the form of a rating candidate list and / or a final rating candidate list.

[0087] Finally, in step S440, a rating for at least one content may be received from at least one user account among the plurality of accounts included in the chat room. According to one embodiment, a rating indicating a preference for one content may be received from the at least one user account. In another embodiment, a rating indicating a preference for at least one content among the plurality of contents may be received from the at least one user account.

[0088] 5 is an exemplary diagram illustrating an operation of sharing a screen related to a first user account (516) in a chat room (514) of an instant messaging application according to an embodiment of the present disclosure and selecting at least one content included in the shared screen (534). Here, the first user account and other user accounts may be included in or participate in the chat room (514). The first operation (510), the second operation (520), and the third operation (530) may include a screen in which the first user account displays the chat room (514) on the display of their user terminal.

[0089] A screen related to a first user account of an instant messaging application can be shared in a chat room including the first user account. To this end, the first user account can perform an input indicating screen sharing in the chat room (514). For example, as shown in the first operation (510), an icon for screen sharing, i.e., a "Watch Together" icon (512) located at the bottom of the chat room (514), can be touched and selected. In the first operation (510), the "Watch Together" icon (512) located at the bottom of the chat room (514) is used for screen sharing, but the present invention is not limited thereto, and any link or icon capable of performing screen sharing in the chat room (514) can be placed at a predetermined location in the chat room (514).

[0090] An input indicating screen sharing may be received by a first user account in the chat room, and a screen related to the first user account may be displayed in at least a portion of the chat room. According to one embodiment, when the "Watch Together" icon (512) displayed in the first operation (510) is touched, an interface for sharing any application or program running on the user terminal on which the first user account is running may be displayed. For example, as shown in the second operation (520), a screen including a shopping page (522) of a shopping application running on the user terminal may be displayed, and a recording icon (524) may be displayed at the bottom of the screen. When the recording icon (524) is touched in the second operation (520), a screen including the shopping page (522) may be output to at least a portion of the chat room (514). FIG. 5 illustrates an intermediate process in which the first user account confirms the screen to be shared before sharing a screen related to the first user account (516) through the second action (520), but is not limited to this. When the "Watch Together" icon (512) is touched, an application or program running on the first user account can be immediately shared in the chat room (514) without an intermediate process.

[0091] At least one content included in the shared screen 534 can be output via the chat room 514. According to one embodiment, a screen including a shopping page 522 is shared to the chat room 514, and at least one content can be selected from the plurality of contents included in the shared screen 534. As shown in a third operation 530, the shared screen 534 can be displayed on the background screen of the chat room 514.

[0092] At least one piece of content included in the shared screen 534 can be selected by any user account included in the chat room 514. According to one embodiment, a first user account can select at least one piece of content included in the shopping page 522. To this end, an input (e.g., a touch input) indicating a selection for a portion corresponding to at least one piece of content included in the shopping page 522 can be received. For example, as illustrated in the third operation 530, touch inputs can be received for a portion 532_1 corresponding to product A content, a portion 532_2 corresponding to product C content, and a portion 532_3 corresponding to product F content included in the shared screen 534. While FIG. 5 illustrates the first user account in the chat room 514 selecting at least one piece of content included in the shared screen 534, other user accounts in the chat room 514 can be configured to select at least one piece of content included in the shared screen 534, without being limited thereto.

[0093] The portions corresponding to each of the plurality of contents included in the shared screen, which can be selected by a user account, can be separated and analyzed in various ways. According to one embodiment, the portion corresponding to the A product content (532_1), the portion corresponding to the C product content (532_2), and the portion corresponding to the F product content (532_3) included in the shared screen (534) can be identified by a page structure set in the shopping page (522). Such a page structure can include a structure in which the system providing the shopping page (522) defines the portions corresponding to each of the plurality of contents on the shopping page (522). In another embodiment, the portion corresponding to the A product content (532_1), the portion corresponding to the C product content (532_2), and the portion corresponding to the F product content (532_3) included in the shared screen (534) can be identified through image recognition processing by the user terminal or a content evaluation system. For example, a processor of a user terminal running an instant messaging application may analyze an image including a shopping page (522) that is a shared screen, and separate and recognize portions corresponding to each of a plurality of contents included in the shopping page (522). As yet another example, a processor of a content evaluation system may receive an image including a shopping page (522) that is a shared screen from a user terminal, and analyze the received image to separate and recognize portions corresponding to each of a plurality of contents included in the shopping page (522).
