(15) The user terminal 100 may be connected to the messenger server 200, and a user of the user terminal 100 may be able to chat with other users through a chatting room on an instant message service provided by the messenger server 200.

(16) The user terminal 100 may receive a content recommendation from the messenger server 200 through the chatting room. The user terminal 100 may be a wireless communication device such as a desktop, a laptop computer, a mobile communication terminal, a PDA, a smart phone, a tablet, a smart TV, and the like.

(17) The messenger server 200 is a computer device connected to the user terminal 100 over a network, and the messenger server 200 may be a server 200 provided with a memory and a processor therein to provide an instant message service to the user.

(18) The messenger server 200 of the present disclosure may provide the instant message service to the user, and the user may chat with other users through the chatting room provided by the messenger server 200.

(19) In the content recommendation system, the messenger server 200 may receive text information from the user terminal and provide at least one keyword-related content based on the text information. In this case, the messenger server 200 may provide the user terminal 100 with a preview content for one of the at least keyword-related content. Specifically, the messenger server 200 may replace the preview content in response to receiving interaction information of the user and provide a replacement preview content to the user terminal 100.

(20) Here, the content may include a character image such as an emoticon and a sticker used by the user in the chatting room.

(21) Hereinafter, an example of a content recommendation method implemented by the user terminal 100 of the present disclosure to will be described.

(22) FIG. 2 is a diagram for explaining an example of a content recommendation method implemented by the user terminal 100 shown in FIG. 1, and FIGS. 3 to 8 are diagrams for explaining a first embodiment of the content recommendation method of the present disclosure shown in FIG. 2.

(23) As shown in FIG. 2, the content recommendation method implemented by the user terminal 100 according to an exemplary embodiment of the present disclosure may include receiving text information in operation S100, selecting keyword information to be mapped to the text information in operation S200, outputting a first content in operation S300, receiving an interaction in operation S400, and outputting a second content in operation S500.

(24) An example in which operations S100 to S500 are sequentially performed is illustrated in FIG. 2, but the present disclosure is not necessarily limited thereto.

(25) Hereinafter, a content recommendation method implemented by the user terminal 100 when text information is mapped to one item of keyword information will be described as a first embodiment, and a content recommendation method implemented by the user terminal 100 when text information is mapped to a plurality of items of keyword information will be described as a second embodiment.

(26) Hereinafter, according to an example shown in FIG. 2, the first embodiment of the content recommendation method of the present disclosure will be described for convenience of description.

(27) Hereinafter, operation S100 of receiving the text information will be described with reference to FIG. 3.

(28) In operation S100, the user terminal 100 may receive the text information from a user participating in a chatting room through a text input window of the chatting room.

(29) For example, in a case where the user wishes to input a text in the chatting room, as shown in FIG. 3, as a chatting room region A3 is reduced, a text input window A1 may come upward and a keyboard region A2 may be displayed under the text input window A1.

(30) As shown in FIG. 3, in a state where the chatting room is displayed in the user terminal 100, the user terminal 100 may receive a first text T1 from the user in the text input window A1 of the chatting window through a keyboard interface displayed in the keyboard region A2.

(31) Hereinafter, operation S200 of selecting the keyword information to be mapped to the text information will be described with reference to FIG. 4. In operation S200, the user terminal 100 may map at least one item of keyword information corresponding to the text information. An example in which, as the keyword information corresponding to one item of text information T1, there is only one item of keyword information, i.e. first keyword information K1, is illustrated in FIGS. 4 to 8.

(32) To this end, at least one item of keyword information according to text information may be pre-stored in the user terminal 100.

(33) For example, the user terminal 100 may be in advance provided with a keyword mapping table for mapping each item of text information with keyword information. The keyword mapping table may be simultaneously stored in the messenger server and the user terminal and may be periodically synchronized.

(34) Accordingly, as shown in FIG. 4, the user terminal 100 may map information on the first text T1 to the first keyword information K1 according to the keyword mapping table.

(35) Then, the user terminal 100 may transmit the keyword information to the messenger server 200. For example, the the messenger server 200 may receive the first keyword information K1 shown in FIG. 4 from the user terminal 100.

(36) Then, the messenger server 200 may select at least one content related to the keyword information from the keyword information. To this end, a content mapping table for mapping keyword information and at least one keyword-related content may be pre-stored in the messenger server 200.

(37) Accordingly, as shown in FIG. 4, for example, when the first keyword information K1 is received from the user terminal 100, the messenger server 200 may select contents E1, E2, . . . , and En to be mapped to the first keyword information K1 from among a plurality of emoticon contents stored in the messenger server 200 according to the content mapping table as keyword-related contents.

(38) The messenger server 200 may bundle at least a part of the selected keyword-related contents into one content group and provide the content group to the user terminal 100. This will be described in more detail with reference to FIG. 5 below.

(39) The messenger server 200 may provide a first preview content for the first content while providing the user terminal 100 with the keyword-related contents. Here, the first content may be any one of the keyword-related contents provided by the messenger server 200 to the user terminal 100.

(40) The messenger server 200 may select a first content E1 from among the keyword-related contents provided to the user terminal 100 as shown in FIG. 4.

(41) Here, the messenger server 200 may select the first content from among the keyword-related contents provided by the user terminal 100 based on at least one of the following: (1) a usage frequency in the user terminal 100, (2) a usage frequency in a user terminal different from the user terminal 100, and (3) a server registration date of the content.

(42) That is, from among the keyword-related contents provided to the user terminal 100, the messenger server 200 may select, as a first preview content, (1) a content most frequently used by a user who has transmitted keyword information, (2) a content most frequently used by another user who transmitted keyword information, or (3) a content with the latest date of registration in the messenger server.

(43) Selection of the first content from among the keyword-related contents provided to the user terminal 100 may be performed in a manner different from that described above. While providing information on a first content group to the user terminal 100, the messenger server 200 may provide thumbnail contents and preview contents of all contents included in the first content group. In addition, the user terminal 100 may select any one of the contents in the first keyword group provided from the messenger server 200 as the first content.

(44) Hereinafter, with reference to FIG. 5, designating keyword-related contents selected by the messenger server 200 as a first content group and a first content set will be described.

(45) The messenger server 200 may provide at least a part of the selected keyword-related contents to the user terminal 100. The messenger server 200 may bundle a predetermined number of keyword-related contents into one content group and provide the content group to the user terminal 100.

(46) As shown in FIG. 5, for example, when the number of keyword-related contents selected by the messenger server 200 is 220 and a predetermined number of contents to be provided to the user terminal 100 at once is 100, the messenger server 200 may select 100 out of the 220 keyword-related contents and designate the 100 keyword-related contents as a first content group.

(47) The messenger server 200 may first provide the first content group to the user terminal 100. In addition, the user terminal 100 may bundle a predetermined number of contents among the contents in the first content group into one content set and output the corresponding content set.

(48) As shown in FIG. 5, for example, when the predetermined number of contents included in one content set is 20, the user terminal 100 may select 20 out of the 100 contents and designate the selected contents as a first content set. While details thereof will be described later with reference to FIG. 6, the user terminal 100 may output the contents in the first content set in operation S300 of outputting the first content. The contents in the first content set may be output in operation S300 of outputting the first content. In addition, the user terminal 100 may select 20 out of the remaining 80 contents other than 20 contents designated as the first content set in the 100 contents and designate the selected contents as a second content set. While details thereof will be described later with reference to FIG. 9, the user terminal 100 may output the contents in the second content set in operation S500 of outputting the second content.

(49) FIG. 5 illustrates that the contents are respectively given unique numbers and the first and second content sets are designated according to the order of the unique numbers of the contents, but the present disclosure is not limited thereto. In fact, the contents may not be given the unique numbers as shown in FIG. 5. In addition, the user terminal 100 may select contents, which are to be included in the first content set and the second content set, randomly or by a predetermined criterion regardless of the order of the unique numbers of the contents.

(50) As such, there may be some cases where the user terminal 100 outputs more than the predetermined number of contents while outputting the contents included in the first content group. Specifically, if the predetermined number is 100, it means that the user terminal 100 outputs all the contents included in the first content group. If the predetermined number is 95, it means that the user terminal 100 outputs only 95 contents included in the first content group, but 5 contents are not output.

(51) When such cases happen, the user terminal 100 may receive additional keyword-related contents from the messenger server 200. The messenger server 200 may reselect 100 contents out of the remaining contents other than the 100 contents already selected as the first content group and provided to the user terminal 100 in the keyword-related contents, and may designate the reselected 100 contents as a second content group.

(52) The messenger server 200 may additionally provide the second content group to the user terminal 100. In addition, the user terminal 100 may bundle a predetermined number of contents among the contents in the second content group into one content set and output the corresponding content set.

(53) Hereinafter, the operation S300 of outputting the first content will be described with reference to FIG. 6.

(54) The operation S300 of outputting the first content may include outputting a first content set in operation S310 and outputting a first preview content in operation S320, and these two operations may be simultaneously performed.

(55) FIG. 6 illustrates an example in which a first content E1 is selected and provided as a first preview content PC1 in operation S300 of outputting the first content. The first content E1 is selected from among contents included in a first content set CS1.

(56) In operation S310 of outputting the first content set, the user terminal 100 may select a predetermined number of contents from among the contents in the first content group provided from the messenger server 200 as the first content set CS1. Referring to FIG. 5, the user terminal 100 may output keyword-related contents E1, E2, . . . , and En in the first content set CS1.

(57) Here, the first content set CS1 may be output in a form in which thumbnail contents of the contents in the first content set CS1 are arranged at a predetermined interval. FIG. 6 illustrates that the thumbnail contents are arranged in three rows and four columns, but the present disclosure is not limited thereto.

(58) Here, the user terminal 100 may output at least one keyword-related content E1, E2, . . . , or En included in the first content set CS1 to be sequentially arranged according to ranking based on popularity. However, the present disclosure is not necessarily limited thereto.

(59) In operation S320 of outputting the first preview, the user terminal 100 may output the first preview content PC1 of the first content E1 provided from the messenger server 200. The first content set CS1 and the first preview content PC1 may be simultaneously output by the user terminal 100.

(60) When providing the first content set CS1 and the first preview content PC1 to the chatting room in which the user is participating, the user terminal 100 may display the first content set CS1 and the first preview content PC1 to be overlaid on some regions of the chatting room.

(61) That is, as shown in FIG. 6, the text input window A1 of the chatting room, the first content set CS1, and the first preview content PC1 may be displayed to be overlaid on some regions of the chatting room.

(62) Here, the first preview content PC1 may be located above the text input window A1 to be overlaid on the chatting room region A3, and the first content set CS1 may be displayed in the keyboard region A2 under the text input window A1.

(63) Hereinafter, operation S400 of receiving the interaction will be described with reference to FIGS. 7A-7B.

(64) In operation S400 of receiving the interaction, the user terminal 100 may receive the interaction from the user.

(65) The interaction may be any of various predetermined input operations of the user. For example, as shown in FIG. 7A, the user terminal 100 may receive a pull to action performed by the user on a display region of the first content set CS1 as an interaction.

(66) Here, the pull to action may refer to an operation in which the user touches the display region of the first content set CS1 with a finger and then pulls and releases the display region in a specific direction. For example, as shown in FIG. 7A, the pull to action may be performed by the user's touching the display region of the first content set CS1 in a downward direction as indicated by an arrow and then pulling and releasing the display region.

(67) In addition, as shown in FIG. 7B, the user terminal 100 may receive an input of clicking a random button RB provided in the user terminal 100 as an interaction. The random button RB may be a touch button that the user terminal 100 outputs to a display unit.

(68) Various methods for an interaction may be determined according to a user's selection, a service provider's selection, or a function supported by an operating system of the user terminal 100.

(69) Hereinafter, operation S500 of outputting the second content will be described with reference to FIG. 8.

(70) In operation S500 of outputting the second content, the user terminal 100 may output a second preview content together in operation S510 while outputting a second content set in operation S520.

(71) Operation S500 of outputting the second content may be performed in response to the interaction described above.

(72) In operation S500 of outputting the second content, the user terminal 100 may select, as a second content set CS2, a predetermined number of contents from among the remaining contents other than the contents designated as the first content set SC1 in the contents of the first content group provided from the messenger server 200, as shown in FIG. 5. Therefore, the first content set CS1 and the second content set CS2 may include different contents.

(73) In operation S510 of outputting the second content set, the second content set CS2 may be output to replace the first content set CS1. Specifically, as shown in FIG. 8, the user terminal 100 may replace the first content set CS1 previously displayed in the keyboard region A2 with that the second content set CS2, so that the second content set CS2 can be displayed.

(74) In operation S520 of outputting the second preview content, a second preview content PC2 different from the first preview content PC1 may be output. The second preview content PC2 may be output to replace the first preview content PC1.

(75) The second preview content PC2 may be a preview content for a second content E7. The second content E7 may be a content selected from the second content set.

(76) Hereinafter, another embodiment of operation S500 of outputting the second content will be described with reference to FIG. 9.

(77) As shown in FIG. 9, the second content set CS2 may include contents which are the same as the contents included in the first content set CS1, but which are shuffled to have a different output arrangement.

(78) For example, all of the contents included in the second content set CS2 illustrated in FIG. 9 are included in the first content set CS1. However, the second content set CS2 has an output arrangement of the contents different from that of the first content set CS1.

(79) Although not illustrated in the drawings, the second content set CS2 may be output with the same contents as those of the first content set CS and in the same output arrangement as that of the first content set CS1. In this case, it may be seen that only operation S520 of outputting the second preview content is performed in operation S500 of outputting the second content. That is, the content set does not change, but only the preview content is replaced.

(80) As shown in FIG. 8 or FIG. 9, after operation S500 of outputting the second content is performed, the user terminal 100 may receive information that a user selects any one of at least one keyword-related content included in the second content set CS2 and the second preview content PC2, as shown in FIG. 8 or FIG. 9. Then, the user terminal 100 may display the content selected by the user in the chatting room.

(81) For example, when the second content E7 corresponding to the second preview content PC2 is clicked and selected by the user from each keyword-related content in the second content set CS2 and the second preview content PC2 as shown in FIG. 9, the second content E7 corresponding to the second preview content PC2 may be displayed in the chatting room as shown in FIG. 10.

(82) As such, in the content recommendation method according to an exemplary embodiment of the present disclosure, while at least one keyword-related content for text information received from the user terminal 100 and a preview content therefor are provided, the preview content is replaced by at least one keyword-related content in response to the user's action, so that the user can enjoy a desired content more conveniently.

(83) The content recommendation method according to the first embodiment of the present disclosure has been described with an example in which there is one item of keyword information to be mapped to text information. Hereinafter, a case in which there is a plurality of items of keyword information to be mapped to text information will be described as a second embodiment.

(84) FIGS. 11 to 13 are diagrams for explaining a second embodiment of the content recommendation method of the present disclosure shown in FIG. 2. FIGS. 14A-14B are diagrams for explaining a first modified example of a content recommendation method according to the second embodiment. FIGS. 15A-15B are diagrams for explaining a second modified example of the content recommendation method according to the second embodiment.

(85) In FIGS. 11 to 15, differences from FIGS. 1 to 10 will be mainly described while the same description as that of FIGS. 1 to 10 is omitted.

(86) The content recommendation method according to the second embodiment of the present disclosure may include receiving text information in operation S100, selecting keyword information to be mapped to the text information in operation S200, outputting a first content in operation S300, receiving an interaction in operation S400, and outputting a second content in operation S500.

(87) Hereinafter, operation S200 of selecting the keyword information to be mapped to the text information will be described with reference to FIG. 11. In the content recommendation method according to the second embodiment of the present disclosure, there may be a plurality of items of keyword information to be mapped to one item of text information input to the user terminal.

(88) Here, the user terminal 100 may transmit the plurality of items of keyword information to be mapped in operation S200 to the messenger server 200. Accordingly, the messenger server 200 may receive information on each of the plurality of items of keyword information and select at least one keyword-related content for each of the plurality of items of keyword information.

(89) For example, as shown in FIG. 11, the keyword information to be mapped to the information on the first text T1 received by the user terminal 100 may include first keyword information K1, second keyword information K2, and third keyword information K3.

(90) In this case, the messenger server 200 may receive the first keyword information K1, the second keyword information K2, and the third keyword information K3 in operation S100 of receiving the keyword information.

(91) The messenger server 200 may select at least one keyword-related content Ea1, Ea2, . . . , or Ean having the first keyword information K1 for the first keyword information K1 as a first keyword group KG1. In addition, the messenger server 200 may select at least one keyword-related content Eb1, Eb2, . . . , or Ebn having the second keyword information K2 for the second keyword information K2 as a second keyword group KG2. In addition, the messenger server 200 may select at least one keyword-related content Ec1, Ec2, . . . , or Ecn having the third keyword information K3 for the third keyword information K3 as a the third keyword group KG3.

(92) Hereinafter, operation S300 of outputting the first content and operation S400 of receiving the interaction will be described with reference to FIG. 12.

(93) Here, in operation S300 of outputting the first content, the user terminal 100 may select the first content set CS1 from the first keyword group and the second keyword group provided from the messenger server 200. The first content set CS1 may include a first keyword set KS1 and a second keyword set KS2.

(94) A display region of the first content set CS1 in the user terminal 100 may be displayed separately by each of the plurality of items of keyword information according to a preset criterion.

(95) For example, as shown in FIG. 12, the display region of the first content set CS1 may include a region of the first keyword set KS1 (referred to as first keyword set region) in which at least one keyword-related content having the first keyword information K1 is displayed, and a region of the second keyword set KS2 (referred to as a second keyword set region) in which at least one keyword-related content having the second keyword information K2 is displayed. The first keyword set region and the second keyword set region may be divided.

(96) In this case, in FIG. 10, an region of the third keyword set KS3 (referred to as a third keyword set region) in which at least one keyword-related content having the third keyword information K3 needs to be displayed, but the third keyword set region is omitted in the drawings.

(97) However, as shown in FIG. 9, when there are three items of keyword information to be mapped, three keyword set regions may be displayed in the display region of the first content set CS1. When there are two items of keyword information to be mapped, two keyword set regions may be displayed.

(98) Thereafter, as shown in FIG. 10, when the user performs a pull to action in a direction as indicated by an arrow and the user terminal 100 receives an interaction, operation S500 of outputting the second content may be performed as shown in FIG. 11.

(99) Hereinafter, operation S500 of outputting the second content will be described with reference to FIG. 13.

(100) In operation S500 of outputting the second content, any one content selected from at least one keyword-related content having the second keyword information K2 different from the first keyword information K1 may be output as the second preview content PC2, as shown in FIG. 13.

(101) For example, when a first content Ea1 in the first keyword set KS1 is provided as the first preview content PC1 in operation S300 of outputting the first content, as shown in FIG. 12, a second content Eb2 in the second keyword set KS2 may be provided as the second preview content PC2 in operation S500 of outputting the second content, as shown in FIG. 13.

(102) However, the present disclosure is not necessarily limited thereto, and it is also possible that a content other than the content selected as the first preview content PC1 in the at least one keyword-related content is selected as the second preview content PC2.

(103) For example, a content located at a point where the pull to action starts in the first content set CS1 of operation S300 of outputting the first content may be selected as a preview content in operation S500 of outputting the second content.

(104) FIG. 13 illustrates an example in which, in operation S500 of outputting the second content, the second content set CS2 is provided in the same manner as the first content set CS1 provided in operation S300 of outputting the first content.

(105) Hereinafter, a modified example in which the first content set CS1 and the second content set CS2 are displayed will be described with reference to FIGS. 14A-14B.

(106) As shown in FIGS. 14A-14B, the first content set CS1 and the second content set CS2 may be provided in different arrangement in response to an interaction.

(107) Specifically, as a first modified example of the second embodiment, as shown in FIGS. 14A-14B, the arrangement of the first keyword set KS1 and the second keyword set KS2 displayed in the display region of the second content set CS2 in operation S500 of outputting the second content may be different from the arrangement of the first keyword set KS1 and the second keyword set KS2 displayed in the display region of the first content set CS1 in operation S300 of outputting the first content.

(108) More specifically, in operation S300 of outputting the first content according to the first modified example, the first keyword set KS1 may be located at the top in the region of the first content set CS1 and the second keyword set KS2 may be located under the first keyword set KS1, as shown in FIG. 4A. However, in operation S500 of outputting the second content, in the region of the second content set CS2, the second keyword set KS2 may be located at the top in the region of the second content set CS2 and the first keyword set KS1 may be located under the keyword set KS2, as shown in FIG. 14B.

(109) As such, in the first modified example of the second embodiment of the present disclosure, a plurality of keyword sets may be provided in different arrangement depending on operation of outputting the first content and operation of outputting the second content.

(110) Hereinafter, a modified example in which the first content set CS1 and the second content set CS2 are displayed will be described with reference to FIGS. 15A-15B.

(111) In a second modified example of the second embodiment, as shown in FIG. 13, the arrangement of at least one keyword-related content in each region of the first and second keyword sets KS1 and KS2 in operation S500 of outputting the second content may be different from the arrangement of at least one keyword-related content in each region of the first and second keyword sets KS1 and KS2 in operation S300 of outputting the first content.

(112) For example, at least one keyword-related content included in each of the first and second keyword sets KS1 and KS2 in operation S500 of outputting the second content, as shown in FIG. 15B, may be provided in different arrangement from that of at least one keyword-related content included in each of the first and second keyword sets KS1 and KS2 in operation S300 of outputting the first content, as shown in FIG. 15A.

(113) So far, the content recommendation method according to the present disclosure has been described. Hereinafter, an example of the user terminal 100 implementing the content recommendation method of the present disclosure will be described.
