  Each of the plurality of terminals 310 may have an internal configuration that is the same as or similar to the internal configuration of the electronic device 1 (110) described with reference to FIG. 2, and is connected to the server 150 via the network 170 to provide a messaging service. You may receive the offer. At this time, it is assumed that the users of the plurality of terminals 310 are users registered in the messaging service, and at least one account is generated and registered for each user.

  Server 150 may be a device that provides messaging services to a plurality of terminals 310 or a combination of devices. For example, the server 150 may generate an interactive session between two or more terminals (for example, the first terminal 311 and the second terminal 312) of the plurality of terminals 310, and manage the generated interactive session. The chat conversation between the users who participated in the conversation session may be processed by routing an instant message transmitted and received in the generated conversation session.

  In the present embodiment, the server 150 may include a user database 320, a consultation partner database 330, and a dialogue record database 340, as shown in FIG. In some embodiments, the user database 320, the consultation partner database 330, and the dialogue record database 340 may be included in another device that communicates with the server 150 via the network 170. In this case, the server 150 may access the user database 320, the consultation partner database 330, and the dialogue record database 340 by communicating with another device.

  User database 320 may include information regarding users registered with the messaging service. For example, the server 150 may identify a specific user by the above-described account, and associate various information about the user (for example, password, phone number, personal relationship information, device information, interactive session information, etc.) with the account. May be managed by the user database 320. For example, the server 150 associates the telephone number of a specific user, an account of another user who has a personal relationship with the specific user in the messaging service, and the like in the user database 320 in association with the account “aaa” of the corresponding user. May be stored and managed. As a more specific example, when the user of the first terminal 311 accesses the server 150, the server 150 is based on the user's account of the first terminal 311 and the dialogue in which the user's personal relationship information or the user's account participates. Information about the session may be retrieved from the user database 320 and provided.

  The consultation partner database 330 may include information related to an account selected in advance among accounts registered in the messaging service. Here, the account selected in advance may include, as an example, a consultation partner account of a user registered in advance as a consultation partner. At this time, the server 150 may manage a variety of information related to the consultation partner account in the consultation partner database 330. For example, the server 150 may store and manage information such as a consultation partner profile and a consultation field in the consultation partner database 330 in association with the corresponding consultation partner account.

  The dialogue record database 340 may include a dialogue record by an instant message transmitted / received in a dialogue session with another account by a previously selected account such as a consultation partner account for each dialogue session. For example, when the consulting partner A accesses the server 150 from the second terminal 312 using the consulting partner account a, and the general user B requests a dialogue from the first terminal 311 using the account b, the server 150 A dialogue session (hereinafter referred to as a “consultation dialogue session”) between the consultation partner account a and the account b is set and managed. Further, the server 150 may store and manage a dialogue record by an instant message transmitted and received in the consultation dialogue session in the dialogue record database 340 in association with the corresponding consultation dialogue session.

  At this time, the dialog record stored in the dialog record database 340 may be provided not only to the user who participated in the corresponding dialog session but also to other users who have not participated in the corresponding dialog session. For example, the dialogue record between the consultation partner A and the general user B may be provided to the general user C of the account c accessing the server 150 from the third terminal 313, which is not related to the above-described consultation dialogue session.

  As a more specific example, it is assumed that the general user B requests the consultation partner A for advice regarding “purchase of HDTV (High Definition Television)” and the consultation partner A responds to the consultation of “purchase of HDTV”. In this case, the dialogue record regarding “purchase HDTV” may be stored in the dialogue record database 340 via the server 150. At this time, when the user C transmits the search term “HDTV” to the server 150, the server 150 searches the dialogue record database 340 using “HDTV” as a keyword, and a dialogue related to “purchase HDTV”. The record may be transmitted to the third terminal 313 as a search result. Therefore, the user C can obtain a dialogue between the consultation partner A and the general user B, which is a consultation record related to “HDTV”, and can refer to this. At this time, depending on the search word, a consultation record that the user C consulted with the consultation partner A or another consultation partner may be provided as a search result.

  FIG. 4 is a block diagram showing an example of components that can be included in the processor of the server in one embodiment of the present invention, and FIG. 5 is a diagram of what the server executes in one embodiment of the present invention. 6 is a flowchart illustrating an example of a method that can be performed.

Here, the components of the processor 222 may be representations of different functions of the processor 222 that are executed by the processor 222 in accordance with instructions provided by program code stored in the server 150. For example, the interactive session setting unit 410 may be used as a functional expression of the processor 222 in which the processor 222 sets an interactive session between two or more accounts according to the above-described instructions.

  In operation 510, the interactive session setting unit 410 may set an interactive session between accounts registered in the messaging service. For example, the user A may access the server 150 using the terminal A in which the messenger application is installed, and the server 150 may recognize the account a of the user A. When the user A requests the server 150 to interact with the user B who has the account b using the messenger application, the conversation session setting unit 410 establishes a conversation session between the account a and the account b as a response to the request. May be set.

  In operation 520, the message routing unit 420 may route an instant message transmitted / received in the set interactive session. The message routing unit 420 may control the server 150 to transmit the instant message received by the server 150 to the destination. For example, in the interactive session between the account a and the account b described above, an instant message transmitted from the terminal A of the account a may be transmitted to the terminal B of the account b via the server 150.

  In operation 530, the dialog record storage unit 430 stores, in the database for each dialog session, a dialog record based on an instant message transmitted and received by each account previously selected from accounts registered in the messaging service in a dialog session with another account. May be stored. For example, when the above account a is an account selected in advance, an instant message transmitted / received in an interactive session set between the account a and the account b may be stored in the database as one interactive record. Here, the database may correspond to the dialogue record database 340 described with reference to FIG. 3 as an example. In other words, the dialogue record storage unit 430 may control the server 150 to store an instant message transmitted / received in a dialogue session in which a preselected account participates in a database in association with the corresponding dialogue session.

  In operation 540, the search word receiving unit 440 may receive a search word from a user of a first account among accounts registered in the messaging service. For example, the server 150 may provide a user terminal with a function for inputting a search term in a messaging service. As an example, the function may be provided through a messenger application installed in the terminal. When the user inputs a search word using the function at the user's terminal, the input search word may be transmitted to the server 150, and the search word receiving unit 440 uses the search word received by the server 150 as the search word. You may confirm in connection with a 1st account.

  In operation 550, the dialog record search unit 450 may search the database for a dialog record corresponding to the search term for each dialog session. For example, each of the dialogue record for the dialogue session a, the dialogue record for the dialogue session b, and the dialogue record for the dialogue session c may be searched as individual search items.

  In operation 560, the dialogue record providing unit 460 may classify at least one dialogue record among the retrieved dialogue records as a corresponding dialogue session and provide it to the user of the first account. For example, the dialog record providing unit 460 generates information for configuring a search result screen including at least one dialog record as a search result, and the generated information is transmitted to the user terminal of the first account via the network 170. Server 150 may be controlled to be transmitted. The user of the first account can refer to the dialog record of another user by receiving the dialog record by the search term.

  From the point of view of the user of the first account, since a record of the interaction of the user himself / herself with the user of the account selected in advance is also stored in the database, an interaction record of the interaction session in which the user himself participated is provided depending on the search term. Sometimes. In addition, a user of an account selected in advance can receive a desired dialogue record by searching. At this time, depending on the search word, the user's own dialogue record may be included as a search result. On the other hand, the dialogue record stored in the database may include a dialogue record by an instant message transmitted / received in a dialogue session with a third account of accounts registered with a second account of pre-selected accounts. . At this time, the first account, the second account, and the third account may be different from each other. In other words, the user of the first account can be provided with a dialogue record of a dialogue session in which he / she is not participating.

  Here, the account selected in advance may include a consultation partner account of a user registered in advance as a consultation partner. In this case, the dialogue record stored in the database may include a consultation record stored in the database for each consultation partner account or each dialogue session.

  FIG. 6 is a diagram showing an example of a dialog record stored in a database according to an embodiment of the present invention. The database 600 may correspond to the dialogue record database 340 described with reference to FIG. 3, and as shown in FIG. 6, shows an example of dialogue records stored for each consultation session as well as for each consultation partner account. ing. FIG. 6 shows a consultation partner account item 610, a dialogue session item 620, and a dialogue record item 630. For example, “dialog record 1” may include an instant message transmitted and received in “dialog session a” in which the consultant of “consultation partner account A” participated. When “dialog record 1” is retrieved by matching “dialog record 1” with the search word received by the search word receiving unit 440 in step 540 of FIG. 4, “dialog record 1” is the user of the first account. The user of the first account will be able to view “Dialogue Record 1”.

A screen 710 in FIG. 7 shows an example of a chat room screen for dialogue between the user of the first account and the artificial intelligence account. Here, the artificial intelligence account may be a bot account that mediates between a consultation partner such as an expert and a user, or guides a user to input a search term to search for a related dialogue. . Such a chat room may correspond to an interactive session between the first account and the artificial intelligence account, and the message “advice for HDTV purchase” 720 entered by the user of the first account in such a chat room is searched. It may be transmitted to server 150 as a word. At this time, if it is difficult to understand the meaning by dividing the question into a plurality of instant messages, the artificial intelligence account requests the user to transmit the contents of the question in one instant message. Also good. At this time, the AI account defines predefined cases such as simple greetings, bad words, pictograms, repetitions of the same sentence or word, forbidden words, and response messages for such cases. You can use it. In addition, the artificial intelligence account may ask the consultant to consult with the consultant to mediate the consultant according to one question, and all other questions entered after such a consult request will be entered as a new search term. May be processed as

  In some embodiments, the messenger application may provide another user interface for search term input. For example, the main screen or chat room screen of the messenger application may include an icon for searching, and the user selects the corresponding icon (for example, the user can touch the area where the icon is displayed in the touch screen environment with the finger. If touched, a user interface for inputting a search term may be provided to the user.

The mediation function for searching for and recommending a consultant will be described in more detail below.

  FIG. 8 is a diagram illustrating a screen example of a user interface for providing a dialog record according to an embodiment of the present invention. A screen 810 of FIG. 8 shows an example in which items of a dialog record searched based on an input search term are provided in the form of a list arranged by dialog session. At this time, the dialog record item may include a preview content for the content of the dialog record. For example, the dialog record providing unit 460 may generate and provide a preview list of searched dialog records. At this time, the dialogue record providing unit 460 extracts the core question and the core response from each of the searched dialogue records, and displays a list of items for displaying the information about the corresponding consultant, the core question, and the core response in the preview list. May be generated. For example, the information on the consulting partner may include account information of the consulting partner and / or identification information such as a nickname of the consulting partner, and a profile image of the consulting partner. The core question may be selected from messages input by the user who requested the consultation in the corresponding consultation, and the core answer may be selected from messages input by the consultation partner. The method for extracting such core questions and core responses will be described in more detail below.

  When the user of the first account selects one of the items of the dialog record provided in the form of a list, an instant message of the selected dialog record may be provided to the user of the first account in the form of a chat window. .

  FIG. 9 is a diagram illustrating an example in which a dialogue record is provided in an embodiment of the present invention. A screen 910 in FIG. 9 shows an example in which a dialogue record between the consultation partner A and another user is provided to the user of the first account. For example, the screen 910 may be an example of a screen provided when the user of the first account selects an item of dialogue recording for the consultation partner A on the screen 810 of FIG.

  In step 1110, the consultant information management unit 1010 may manage consultant information regarding each consultant account. For example, the consultation partner information management unit 1010 may control the server 150 so as to manage the consultation partner information in the consultation partner database 330 described with reference to FIG. Such a step 1110 may be performed before the step 540 described with reference to FIG. In one embodiment, step 1110 may be performed before step 510.

  In operation 1120, the consultant account selection unit 1020 may select at least one consultant account from the consultant accounts using the search term and the consultant information received from the user of the first account. As an example, the consultation partner account selection unit 1020 may select the consultation partner account by comparing the field of the search term and the field set for the consultation partner. A more specific method for selecting a consultant account will be described in more detail below.

  In operation 1130, the list providing unit 1030 may generate a consultation partner recommendation list including at least one selected consultation partner account and provide the consultation partner recommendation list to a user of the first account. For example, the list providing unit 1030 may control the server 150 such that the generated consultation partner recommendation list is transmitted to the terminal of the user of the first account via the network 170.

  Here, steps 1120 and 1130 may be performed in parallel with steps 550 and 560 described with reference to FIG. In other words, steps 550 and 560 may be a process of searching and providing a dialog record based on the search term received in step 540, and steps 1120 and 1130 are consultations based on the search term received in step 540. It may be a process of searching for and recommending a partner. In FIG. 11, it is assumed that steps 550 and 560 are executed after steps 1120 and 1130.

  In operation 1140, the dialogue session setting unit 410 may set a dialogue session between the consultation partner account of the first consultation partner selected from the user of the first account in the consultation partner recommendation list and the first account. For example, when one consultation partner is selected from the consultation partner recommendation list provided to the user of the first account, information on the consultation partner selected on the terminal of the user of the first account (for example, the first consultation partner (Consultation partner account) may be transmitted to the server 150. At this time, the dialogue session setting unit 410 may set a dialogue session between the received consultation partner account and the first account. In this case, the user of the first account may be provided with a chat room with a consultation partner corresponding to the set interactive session, and may send and receive an instant message with the consultation partner in the provided chat room.

  In another embodiment, the dialogue session setting unit 410 pushes a message for requesting a consultation to a searched consultation partner, and a dialogue session is established between each consultation partner who responds to the consultation request and the user of the first account. May be generated.

  In operation 1150, the dialogue record storage unit 430 sets the dialogue record by the instant message transmitted / received in the set dialogue session as the consultation record of the first consultation partner, and further stores it in the database in association with the set dialogue session. Good. The database referred to here may correspond to the dialog record database 340 described with reference to FIG.

  FIG. 12 is a diagram showing an example of a user interface screen for providing a consultation partner recommendation list according to an embodiment of the present invention. A screen 1210 in FIG. 12 shows an example in which a consultation partner recommendation list searched based on an input search word is displayed. The items in the consultant recommendation list may correspond to the recommended consultant, and may include information about the consultant's profile image, consultant's consultant account (or identification information such as a nickname), and consulting fields. . As the consultation field of the consulting partner, a field selected by the consulting partner from a variety of preset fields such as TV, automobile, electronic device, and clothing, or a field directly input by the consulting partner may be set. For example, the server 150 may allow the consultation partner to directly select the consultation field from the consultation partner page provided to the consultation partner.

  When the user selects one item (one consultation partner) from the consultation partner recommendation list, the consultation partner account of the selected consultation partner may be transmitted to the server 150, and the server 150 may consult the consultation partner of the selected consultation partner. An interactive session may be established between the account and the first account.

  FIG. 13 is a diagram illustrating an example of providing information on a consultation partner selected from the consultation partner recommendation list according to an embodiment of the present invention. When the user selects a specific consultation partner (consultation partner D) on the screen 1210, information regarding the selected consultation partner may be provided to the user in the form of a pop-up 1310. At this time, the pop-up 1310 may include information such as when the recent activity of the consultant D is performed and how much dialogue (or consultation) has been processed. The pop-up 1310 may further include information on the number of “hearts received” by the consulting partner D. Here, “heart” means an evaluation signal provided to the consultation partner according to the consultation result by the user, and the higher the number of “received hearts”, the higher the number of positive evaluations. You can do it. The “interact” button 1320 may be a user interface for the user to request an interaction with the consultation partner D. When the user selects the “dialog” button 1320, the server 150 may receive a dialogue request from the user's terminal, and in response to the received dialogue request, the user's first account and the consultation partner account of the consultation partner D You may set up an interactive session between.

  FIG. 14 is a diagram showing an example of interaction between a user and a consultation partner in an embodiment of the present invention. The screen 1410 of FIG. 14 shows that a dialogue session is set and set between the user's first account and the consultation partner account of the consultation partner D when the user selects the “interact” button 1320 of FIG. An example is shown in which a consultation is performed between a user and a consultation partner D in a chat room corresponding to an interactive session. At this time, if there is no other instant message transmission / reception for a certain period of time (for example, one hour) after the last instant message transmission / reception, the server 150 determines whether or not the user and the consultation partner account. The set interactive session may be automatically terminated. In general, an interactive session between users having a personal relationship is maintained continuously unless the user explicitly indicates termination. However, since the dialogue session according to the embodiment of the present invention is not only used to store a dialogue record, but is less likely to be used again after the end of the consultation, the server 150 may send an instant message over a certain period of time. When the transmission / reception is not performed, the cost for maintaining the interactive session can be reduced by terminating the relevant interactive session.

  On the other hand, the server 150 may provide a function for consultation with a consultation partner corresponding to the dialogue record based on the dialogue record provided to the user.

  FIG. 15 is a block diagram showing an example of components that can be further included in a processor of a server in still another embodiment of the present invention, and FIG. 16 is a server in still another embodiment of the present invention. Is a flowchart illustrating an example of a method that can be further executed.

  The processor 222 of the server 150 includes a dialog session setting unit 410, a message routing unit 420, a dialog record storage unit 430, a search word reception unit 440, a dialog record search unit 450, and a dialog that are the components described with reference to FIG. In addition to the record providing unit 460, a dialog application function providing unit 1510 may be further provided as shown in FIG. Such processor 222 and components of processor 222 may further perform steps 1610 and 1630 of FIG.

  As described above, the pre-selected account described in step 530 of FIG. 5 may include a user's consultation partner account registered in advance as a consultation partner.

  In step 1610, the dialog application function providing unit 1510 sets the dialog session between the corresponding consultant account and the first account for each of at least one dialog record provided to the user of the first account. A dialog application function may be further provided. For example, a user interface for consultation with the corresponding consultation partner may be added to each item of the list described with reference to FIG. 8 or the dialog record described with reference to FIG.

  In operation 1620, the dialog session setting unit 410 is responsive to the selection of the dialog application function provided for a specific dialog record among the at least one dialog record, and corresponds to the specific dialog record. An interactive session between the consultation partner account of the one consultation partner and the first account may be set. Such a dialogue application function will be described in more detail with reference to FIGS. 17 and 18.

  In operation 1630, the dialogue record storage unit 430 sets the dialogue record by the instant message transmitted / received in the set dialogue session as the consultation record of the first consultation partner, and further stores it in the database in association with the set dialogue session. It's okay. Here, the database may correspond to the dialogue record database 340 described with reference to FIG.

  FIG. 17 is a diagram illustrating an example in which a dialog application function is provided in an embodiment of the present invention. In FIG. 17, a screen 1710 shows an example in which dialog record items searched based on an input search term are provided in the form of a list arranged by dialog session. At this time, unlike the screen 810 of FIG. 8, the screen 1710 shows a state in which “interactive” buttons 1720 to 1750 for applying a dialog with the corresponding consultation partner are added to the items in the list. For example, when the user selects the “interact” button 1750, the server 150 may be requested to interact with the consultation partner A. At this time, the server 150 does not provide a function for browsing the dialogue record of the corresponding item, but sets a dialogue session between the consultation partner account of the consultation partner A and the first account of the user. May be able to communicate with consultant A.

  FIG. 18 is a diagram showing another example in which a dialog application function is provided in an embodiment of the present invention. A screen 1810 in FIG. 18 shows an example in which the user of the first account is provided with a dialogue record with a user different from the consultation partner A. At this time, unlike the screen 910 of FIG. 9, the screen 1810 shows a state where an “interactive” button 1820 is added to the upper end of the interactive recording. For example, when the user selects the “interact” button 1820, the server 150 may be requested to interact with the consultation partner A. At this time, the server 150 may set a dialogue session between the consultation partner account of the consultation partner A and the first account of the user so that the user can interact with the consultation partner A.

  FIG. 19 is a flowchart showing an example of an index creation process in an embodiment of the present invention. Steps 1910 to 1940 in FIG. 19 may be executed by the dialogue record storage unit 430 described with reference to FIG. 4 and may be included in step 530 described with reference to FIG. Such steps 1910 to 1940 may be performed to generate an index for the interaction record.

  In operation 1910, the dialog record storage unit 430 may find and isolate the context of the instant message associated with the subject in the first dialog record of the dialog records. For example, the dialogue record storage unit 430 includes the time at which the instant message included in the first dialogue record was transmitted / received, whether the instant message includes a greeting, and the core keyword related to the search term of the instant message. The context may be determined using at least one of whether or not it is included. As a more specific example, when the dialogue record storage unit 430 includes an important keyword within a certain message interval in an instant message continuously transmitted and received within a certain time, the corresponding instant message is included in one context. The context may be separated from the first dialogue record by grasping it as applicable. At this time, the instant message including the greeting may be used to determine the starting point of the corresponding context. Such context separation may be used to extract dialogs for a single subject because multiple consultations may be made in one dialog session.

  In operation 1920, the dialogue record storage unit 430 may remove unnecessary words from the separated context. For example, the dialogue record storage unit 430 may include at least one of a sentence composed of a preset greeting sentence, a sentence composed of a preset simple reaction, and a sentence including the content of repetition of a previous sentence. May be removed as unnecessary words. As a more specific example, is such a simple reaction such as greeting statements or such as "Hello", "Yes" and "Yes", the core text of the context considered to have a low relationship, was removed as unnecessary words It's okay. The dialogue record storage unit 430 may store and manage the types of such greetings and simple reactions in advance, and if the pre-stored greetings and simple reactions are included in the context, the corresponding greetings are stored. Sentences and simple reactions may be removed from the context. In addition, the previous sentence may be repeated. For example, the same content may be repeated in the sense that the consultant confirms the question of the questioner. Such repeated sentences may be removed as unnecessary words because they have a low relationship with the core sentence of the context.

  In step 1930, the dialogue record storage unit 430 may set the sentence of the instant message transmitted / received before the time when the preset positive evaluation signal is input as the core sentence in the context where the unnecessary word is removed. . For example, if a user enters a message with a positive rating for a consultation, such as “Thank you” or “Helpful”, before the message is entered Has a high probability that the user's desired response is obtained from the consultant. Accordingly, the dialogue record storage unit 430 determines that a message including a positive evaluation is a preset positive evaluation signal, and instant messages transmitted and received before the time when the preset positive evaluation signal is input. A weight value may be set by setting a sentence of (instant message transmitted / received within a certain time before the time point or a certain number of instant messages transmitted / received before the time point) as a core sentence.

  In the dialog record preview described with reference to FIG. 8, the core question and the core response may be extracted through the processes of steps 1910 to 1930.

  In operation 1940, the dialog record storage unit 430 sets the field of the first dialog record, the field preset for the consultation partner corresponding to the first dialog record, and other dialogs in the same field as the field of the first dialog record. An additional tag for the first dialog record may be assigned using at least one of the tags set for the record. For example, the field of dialogue recording related to “HDTV” may be classified into “TV”, “digital home appliance”, and the like. In this case, the dialog record storage unit 430 may tag “HDTV”, which is a subject related to the dialog record, and add “TV” or “digital home appliance”, which is the field of the dialog record, as an additional tag to the corresponding dialog record. . As another example, the dialogue record storage unit 430 may grasp the field set for the consultation partner of the first dialogue record. When the fields set for the consultation partner of the first dialog record are “TV”, “electronic device”, and “digital home appliance”, “TV”, “electronic device”, And “digital appliances” may be added. As another example, the dialogue record storage unit 430 displays “UHDTV” if “UHDTV (Ultra High Definition Television)” exists in the second dialogue record in the same field as “TV” that is the field of the first dialogue record. An additional tag may be added to the first dialog record.

  FIG. 20 is a flowchart illustrating an example of a search progress process according to an embodiment of the present invention. Steps 2010 to 2030 in FIG. 20 may be executed by the dialogue record search unit 450 and the dialogue record providing unit 460 described with reference to FIG.

  In operation 2010, the dialogue record search unit 450 may extract a keyword from the search term, and search the dialogue record from the database using the extracted keyword. The search term may be input in various forms from a keyword form to a natural language form, and the dialog record search unit 450 extracts the keyword from the input search word and stores the dialog record including the extracted keyword in the database. You can search from.

  In step 2020, the dialogue record search unit 450 determines whether the consultation partner profile information corresponding to the searched dialogue record, whether the consultation partner is a currently available consultation partner, a paid consultation or a free consultation of the consultation partner. The ranking of the retrieved dialogue records may be determined using at least one. For example, when the consultation partner is a consultation partner who can respond at the present time, the dialogue record of the consultation partner may obtain a higher ranking. Also, in the consultant's profile information, the conversation record of the consultant whose field is closer to the search term or the consultant whose number of “received hearts” is large may obtain a relatively higher ranking. . In addition to this, a dialogue record of a consultation partner who consults for a fee may obtain a relatively high ranking. At this time, the server 150 may further include a function for processing a settlement caused by the paid consultation. For example, the server 150 may further provide a simple settlement service to the user. The simple settlement service may be realized using one of well-known techniques.

  Stage 2010 and stage 2020 may be included in stage 550 of FIG.

  In operation 2030, the dialog record providing unit 460 may generate and provide a preview list of dialog records searched based on the determined ranking. For example, the dialogue record providing unit 460 extracts the core question and the core response from each of the searched dialogue records, and generates a list of items for displaying the information about the corresponding consultant, the core question, and the core response as a preview list. You can do it. As described with reference to FIG. 19, the core question and the core response may be selected in steps 1910-1930 described above. Stage 2030 may be included in stage 560 of FIG.

  FIG. 21 is a diagram showing an example of removing unnecessary sentences in one embodiment of the present invention. A screen 2110 in FIG. 21 shows an example of a dialogue record in which the consultation partner A exchanges a dialogue with another user. At this time, interactive recording storage unit 430, like the message 2120, a sentence containing the greeting "Hello" may be removed as unnecessary statement. Further, the dialog record storage unit 430 may determine that the content of the message 2130 overlaps with the message 2140 transmitted / received before the message 2130, and may remove the message 2130 as an unnecessary sentence.

  FIG. 22 is a diagram showing an example of preview content of dialog recording in one embodiment of the present invention. A screen 2210 in FIG. 22 shows an example of a dialog record 2220 searched based on a search word. At this time, the dialogue record 2220 shows an example in which after the unnecessary sentence is removed in FIG. 21, the core question and the core answer are extracted from the remaining sentences and the preview content is configured.

  FIG. 23 is a diagram illustrating an example of a process for matching a user and a consultation partner in an embodiment of the present invention.

  The question reception process 2310 may be an example of a process of receiving a search word from a user. For example, the question reception process 2310 may correspond to step 540 of FIG.

  The question field extraction process 2320 may be an example of a process of extracting a field of a search term received from a user. For example, the field of the search term “advice for HDTV purchase” may be determined as “TV”, “electronic device”, “digital home appliance”, or the like. Such a question field extraction process 2320 may be processed based on a field dictionary 2321 obtained by clustering existing questions.

  The relevant field consultation partner search process 2330 may be an example of a process of searching for a consultation partner corresponding to a search word. The consultation partner may be searched from the consultation partner database 2331. Such a consultation partner database may correspond to the consultation partner database 330 described with reference to FIG.

  Such question field extraction process 2320 and relevant field consultation partner search process 2330 may be included in step 1120 of FIG.

  The request message push process 2340 may be an example of a process of pushing a request message for consultation to a consultation partner selected by the user among the searched consultation partners or the searched consultation partners. For example, the consultation request may be transmitted only to the consultation partner selected by the user, or may be transmitted to all the consultation partners searched. In this case, a dialogue session may be set up between each user and the user who responded to the pushed request message.

  The consultation partner result display process 2350 may be executed in parallel with the request message push process 2340, and may be an example of a process of providing information on the searched consultation partner. As an example, the consultation partner result display process 2350 may correspond to stage 1130 of FIG.

  The function of the consultation partner extraction model may be defined as in the following (1) to (5).

-Consultants with a history of processing or consulting questions similar to the received questions.

  -Consultation partner who was able to consult in the past current time zone.

  -Consultation partners who have a relatively large number of consultations compared to other consultants in the recent fixed period, or whose consultation evaluation is relatively high compared to other consultants in the recent fixed period.

  A consulting partner whose difference between the time when the interactive session is set and the time when the instant message is first transmitted in the set interactive session is relatively short compared to other consulting partners.

  -Consultant with no history of neglecting the consultation after accepting the dialogue request with the pushed request message.

  -Consultation partners who have less than a certain number of consultations in progress (restricted on the assumption that humans cannot handle more than a certain number simultaneously).

  -Consultants with no history (to prevent the consultation from concentrating on consultants with higher ratings).

(3) Hierarchy information (consultation partner in a hierarchy similar to the user)
-For example, weights may be given to men in their 20s in order to preferentially extract men in their 20s.

-Location and location information-Consultation partner located near the user's current location.

  -If the question includes a region name, the consultant located in that region.

  -Consultants selected based on propensity information ascertained by the messaging service.

  -Consultants selected based on other service activities.

  -In the case of a question about a game, a consultant who has a history of installing the application of the corresponding game.

  On the other hand, as a criterion for evaluating the consultation partner extraction model, at least one of the response time of the first dialog, the evaluation score in the user's evaluation, and the browsing time of the dialog record displayed to the third party may be used. For example, if the average response time of the first dialogue is getting faster, the average evaluation score is getting higher, or the browsing time is getting longer, it is judged that the consulting partner extraction model is operating properly. It's okay. On the other hand, if the average response time of the first dialogue is gradually slowing down, the average evaluation score is gradually decreasing, or the browsing time is gradually shortening, the consultation partner extraction model is not operating properly. May be judged. In this case, improvement of the consultation partner extraction model may be attempted by adjusting a weight value between functions of the consultation partner extraction model.
