  Hereinafter, an embodiment of the present invention will be described based on the drawings, taking as an example a chatbot that provides a print service in response to a message from a user as a chatbot.

<Embodiment 1>
FIG. 1 is an overall configuration diagram of a message service system according to an embodiment. The message service system includes user terminal A (10A) to user terminal C (10C), chat service server 14, bot server A (16A) to bot server B (16B), and printer A (18A) to printer B (18B). Is provided.

  User terminal A (10A) to user terminal C (10C) are terminals used by users of the message service, and are information terminals such as smartphones, tablet terminals, and PCs (personal computers). Although the figure shows three terminals, user terminal A (10A), user terminal B (10B), and user terminal C (10C), the number is arbitrary. The user operates the user terminal A (10A) to the user terminal C (10C) to access the chat service server 14 on the cloud 12, and exchanges messages with other users and chatbots. In the following, it is assumed that user A operates user terminal A, user B operates user terminal B, and user C operates user terminal C. User terminal A (10A) to user terminal C (10C) and chat service server 14 are connected via a wired or wireless communication network so that data can be transmitted and received. An example of the communication network is a public line such as the Internet, but may be a dedicated line.

  The chat service server 14 is a cloud server arranged on the cloud 12 and is a server that provides a chat service. The chat service server 14 is composed of one or a plurality of server computers. The chat service server 14 executes all processes related to message exchange, such as message transmission / reception processing for the user terminals A to C and display screen display for message transmission / reception. In addition to processing message exchange between two users, the chat service server 14 can form a group with three or more users and process message exchange within the group (group chat). Furthermore, the chat service server 14 cooperates with the bot server A (16A) and the bot server B (16B), and processes message exchange with respect to the chat bot provided by the bot servers 16A and 16B. Message exchange between the user and the chat bot includes message exchange between one user and the chat bot, and message exchange between a plurality of users and the chat bot.

  The bot server A (16A) and the bot server B (16B) function as a message providing device in the present embodiment. The bot server A (16A) and the bot server B (16B) are installed with a chatbot software robot program for exchanging messages with the user, and execute the program. These bot server A (16A) and bot server B (16B) may be operated by a messenger service account assigned for advertising or commercial use, such as a company or a store. The bot server A (16A) and the bot server B (16B) cooperate with the chat service server 14 via a specific API (Application Programming Interface), exchange messages with the user, and send messages from the user. Automatically reply to and send a message back. The specific API is an API for using the chat service server 14. The API format is arbitrary. For example, a JSON (Javascript Object Notation) API is used, and JSON data in a prescribed format is transmitted to a specific URL of the chat service server 14 by POST or GET. The result is returned as JSON format data.

  When the bot server A (16A) and the bot server B (16B) include an operation instruction in the message from the user, the bot server A (16A) executes specific service contents according to the operation instruction. In this embodiment, when a message from the user includes a print instruction, the bot server A (16A) operates the printer A (18A) or the printer B (18B) in accordance with the print instruction to perform printing. Functions as a “print bot” to process. On the other hand, the bot server 16B can provide an arbitrary service according to an operation instruction from the user. In the figure, two servers, bot server A (16A) and bot server B (18B), are shown, but the number is arbitrary. Also, a single bot server may constitute a plurality of chat bots, or a plurality of bot servers may constitute a single chat bot.

  The bot server A as a chat bot (or printer bot) drives the printer A or the printer B in accordance with setting information relating to the operation of the software robot program registered in advance for each user and executes print processing. These setting information can also be referred to as operating conditions for operating the printer A or the printer B. User A operates user terminal A to input and register setting information for operating printer A, and user B inputs and registers setting information for operating user terminal B to operate printer B. To do.

  The printer A (18A) and the printer B (18B) execute an image print process according to a command from the bot server A.

  FIG. 2 is a functional block diagram of the bot server A (16A). The bot server A includes a communication unit 160, a message reception unit 161, a content analysis unit 162, an operation control unit 163, a response message creation unit 164, a user information storage unit 165, a setting information storage unit 166, and a message storage unit 167 as functional blocks. , And an API gateway 168.

  The communication unit 160 communicates with the chat service server 14 and the printers A and B. The communication unit 160 communicates with the chat service server 14 via the API gateway 168 and exchanges messages. The communication unit 160 outputs the message received from the chat service server 14 via the API gateway 168, that is, the message from the user terminal A to the user terminal C, to the message reception unit 161. In addition, the communication unit 160 transmits the response message created by the response message creation unit 164 to the chat service server 14 via the API gateway 168 (that is, transmits to the user terminal A to user terminal C). Further, the communication unit 160 drives the printers A and B by outputting a print command to the printers A and B according to the command from the operation control unit 163.

  The message reception unit 161 functions as a reception unit, receives a message from the communication unit 160, and outputs the message to the content analysis unit 162. The message includes a message regarding registration of setting information. The message reception unit 161 sequentially stores the received messages in the message storage unit 167.

  The content analysis unit 162 analyzes the content of the received message and outputs it to the operation control unit 163. Specifically, the user identifier (user ID) included in the received message is recognized, and the text portion included in the message is extracted and its syntax analysis is executed. The parsing method is arbitrary. For example, after the input message is decomposed into morpheme units, nouns, adjectives, verbs, and interrogative pronouns are extracted as keywords. When an operation instruction is included in the text part of the message, the content analysis unit 162 analyzes the content of the operation instruction and outputs it to the operation control unit 163. The operation instruction in this embodiment includes a print instruction for the printers A and B and an instruction for setting information of the printers A and B.

  The operation control unit 163 functions as a control unit, and registers setting information regarding the operation of the printers A and B in the setting information storage unit 166 based on the analysis result obtained by the content analysis unit 162. Further, the operation control unit 163 outputs a print command to the printers A and B in response to a message from the user. At this time, if the message from the user is a message from a user who has a use authority by performing a specific operation on the chat bot, the operation control unit outputs a print command in response to the message to execute the print service. In the case of a message from a user who does not have usage authority, in principle, control is performed so that the print service is not executed in response to the message.

  The response message creation unit 164 creates a response message according to the analysis result in the content analysis unit 162 and transmits the response message to the chat service server 14 via the communication unit 160.

  The user information storage unit 165 stores, as a user information table, information on users who use the chat service server 14, particularly information on users who use the chat bot realized by the bot server A. The chat bot is assigned a specific account on the chat service realized by the chat service server 14, and the user designates this account and performs a specific operation to make it usable or authorized (hereinafter referred to as a user authority). This is referred to as “friend registration”) to confirm the use of the chatbot. The user information is, for example, a user ID. Information about the authority of each user may be stored.

  The setting information storage unit 166 stores setting information for each user who uses the chat bot realized by the bot server A as a table. The items of the setting information are, for example, identification information of a printer to be used, a color mode, a paper size, the number of copies, etc. As will be described later, the setting information can be determined according to the content of the service provided by the bot server A. In the case of a print service, it is information about printing, and in the case of a search service, it is information about search conditions. The setting information is information that defines the content of the service, and may include a plurality of items.

  The message storage unit 167 stores a message from the user received by the message reception unit 161 as a history.

  FIG. 3 shows a configuration block diagram of the bot server A. The bot server A is composed of one or a plurality of server computers, and includes one or a plurality of CPUs 16b, a ROM 16c, a RAM 16d, a communication interface (I / F) 16e, an input / output I / F 16f, and a storage device 16g.

  The one or more CPUs 16b read out the bot application stored in the ROM 16c or the storage device 16g, and use the RAM 16d as a working memory to realize a chat bot function. That is, it automatically responds to a message from the user, and when the operation instruction is included in the message from the user, the printers A and B are driven according to the operation instruction. The CPU 16b executes the bot application to realize the message reception unit 161, the content analysis unit 162, the operation control unit 163, the response message creation unit 164, and the API gateway 168 in FIG.

  The communication I / F 16e exchanges messages with the chat service server 14 and outputs a print command to the printers A and B.

  The input / output I / F 16f transmits and receives data to and from an input device such as a keyboard mouse and an output device such as a display device.

    The storage device 16g is composed of a nonvolatile memory such as a hard disk drive (HDD) or a solid state drive (SSD), and stores a bot app, a user information table, a setting information table, And a message management table. The storage device 16g implements the user information storage unit 165, the setting information storage unit 166, and the message storage unit 167 in FIG.

    In this embodiment, the software robot program for realizing the chat bot is executed by the CPU. However, a part of the chat bot may be realized by hardware processing instead of processing by executing the program. The hardware processing may be performed using a circuit such as ASIC or FPGA (Field Programmable Gate Array).

  Next, setting information registration will be described by taking user A and user B as an example.

  FIG. 4 schematically shows setting registration processing by the user A and the user B. When the user A and the user B perform friend registration with respect to the chat bot to which a specific account is assigned on the chat service, the bot server A (16A) assigns a user identifier (user ID) to the user A and the user B, respectively. And a printer identifier (printer ID) for uniquely identifying printer A and printer B. The user ID may use the account on the chat service of the user A and the user B as they are.

Next, the user A transmits a message to the bot server A (16A) via the chat service server 14, specifies the printer A or the printer B, and registers the setting information. For example, the user A specifies the printer A, and sets color information: color paper size: A4 as setting information.
Number of copies: A message designating one copy is transmitted. When the bot server A receives these messages, it analyzes the contents of the messages. When the bot server A interprets the messages as setting information, the user A and the printer A are associated with each other and the setting information is recorded in the setting information table.

The same applies to user B. A message is transmitted to bot server A (16A) via chat service server 14, printer A or printer B is specified, and setting information is registered. For example, after specifying the printer B, the user B sets color information: black and white paper size: letter as setting information.
Number of copies: A message designating two copies is transmitted. When the bot server A receives these messages, it analyzes the contents of the messages. When the bot server A interprets the messages as setting information, the user B and the printer B are associated with each other and the setting information is recorded in the setting information table.

  FIG. 5 shows an example of the setting information table stored in the setting information storage unit 166. For each user, a printer, a color (color mode), a size (paper size), and the number of copies (number of copies) are recorded in association with each other. More specifically, printer identification information, color (color mode), size (paper size), and number of copies (number of copies) are recorded in association with each user identification information.

  As described above, the user A or the user B registers the printer and the setting information by registering the chat bot as a friend, and transmits a message such as “print” to the chat bot by using the desired printer and the desired printing condition. A print service can be executed.

  On the other hand, when user A and user B form the same group and perform group chat, user A may join a chat bot registered as a friend to the group chat. Assuming that user B has not yet registered a friend for the chatbot, user A who has registered the chatbot as a friend and user B who has not registered the friend are mixed in the same group chat. If the chatbot automatically responds to the message of user B who is not registered as a friend and provides a print service, it is inconvenient. Will be used for printing).

  Therefore, in this embodiment, when a plurality of users exchange messages in the group chat, the chat bot identifies the user who transmitted the message, and whether or not the identified user is a user registered as a friend. Identify and provide a print service by automatically responding to a print instruction from a user registered as a friend, but provide a print service by an automatic response to a print instruction from a user not registered as a friend Do not. As a mode in which the print service is not provided, there are a mode in which the print instruction itself is not received (ignored or rejected) and a mode in which the print instruction is received but the print service is not executed (pending). Further, a mode indicating that the print service is not provided (rejection or hold) and a mode not indicating that the print service is not provided (ignore) are also included. In the case where the print instruction is put on hold, the case where the print is permitted when a certain condition is satisfied is included, but in this case also, the print service automatically responds to the print instruction from the user having no use authority. The print service is provided when a certain condition is satisfied. The mode indicating that the print service is not provided is created by responding by creating a message such as “Cannot print” or “Friend registration required for printing”, for example. In an embodiment that does not indicate that it does not provide a print service, it does not create a message and respond. In this case, since it cannot be distinguished from an abnormality (failure) of the chatbot, when a print instruction from the user is repeated, some message may be created and responded.

  FIG. 6 shows a sequence diagram of this embodiment. This is processing between the user terminal A operated by the user A, the user terminal B operated by the user B, and the chat bot. It is assumed that user A, user B, and chat bot participate in the same group chat, user A registers the chat bot as a friend, and user B does not register the chat bot as a friend.

  User A operates user terminal A to register a chatbot as a friend. The chat bot stores the user ID of the user registered as a friend in the user information table of the user information storage unit 165.

Next, the user A performs “print” together with the document as image data in the group chat.
Send a message to the chatbot. The manuscript can be, for example, a photograph designated by the user A, but may be a past message history exchanged in the group chat. In this case, for example, the user A
"Print chat history in this group"
And so on. When the chatbot extracts the user ID included in the message from the user A and determines that the user A is a friend registered by referring to the user information table, the chatbot automatically responds to the message and corresponds to the user A. A print service is executed with the attached printer and setting information. At this time,
"Print completed"
And automatically responds to inform user A that printing is permitted.

On the other hand, user B “prints” together with the manuscript in the group chat.
When the message is sent to the chatbot, the chatbot extracts the user ID included in the message from the user B, and if it is determined that the user B is not a friend registered by referring to the user information table, The print service is not provided by automatically responding to the message, and the “print” message is ignored. Thereby, the user B cannot enjoy the print service by the chatbot, and for the user A, the user B who is not registered as a friend uses the chatbot registered as a friend in the past in the group chat. It is possible to prevent the message history from being printed without permission.

<Embodiment 2>
In the first embodiment, the chatbot ignores a message from the user B who is not registered as a friend, but may further inform the user B that printing cannot be performed.

  FIG. 7 shows a sequence diagram of the present embodiment.

In addition to the sequence of FIG. 6, after the chatbot ignores the message from user B,
"Cannot print"
A message such as the above is created and transmitted to the user B to notify that printing is impossible. This message is a message in the group chat and can be visually recognized not only by the user B but also by other users participating in the group chat, for example, the user A.

  By visually recognizing this message, the user B can recognize that some measure is necessary to execute the print service. User A can also recognize that the print instruction by user B has not been executed by visually recognizing this message.

<Embodiment 3>
In the first embodiment, the chatbot ignores a message from the user B who is not registered as a friend, and may further inform the user B that he / she wants to register a friend.

  FIG. 8 shows a sequence diagram of this embodiment.

In addition to the sequence of FIG. 6, after the chatbot ignores the message from user B,
"You need to register as a friend to print"
Is sent to user B. In addition to this message, the chatbot contact information (for example, URL) is transmitted as a message. By visually recognizing this message, the user B recognizes that the chatbot needs to be registered as a friend in order to execute the print service, and accesses the contact included in the message to register the chatbot as a friend. The chat bot stores the user ID of the user B registered as a friend in the user information table of the user information storage unit 165, and executes the print service in response to the print instruction from the user B that has been ignored.

  As described above, the chatbot can ignore the print instruction from the user B who is not registered as a friend and execute the print instruction in response to the user B registering as a friend.

After user B registers as a friend, in response to this friend registration, “Do you want to execute the previous print instruction?”
May be generated and transmitted to the user B, and the print service may be executed after receiving a confirmation message from the user B.

<Embodiment 4>
In the first embodiment, the chatbot ignores the message from the user B who is not registered as a friend, and further obtains the permission of the other user in the group chat in which the chatbot is registered as a friend from the user B. You may be encouraged to do so.

  FIG. 9 shows a sequence diagram of the present embodiment.

In addition to the sequence of FIG. 6, after the chatbot ignores the message from user B,
"Please get permission from @User A or @User C to print"
Is created and transmitted to the user B. Here, the user A and the user C are users who have registered chatbots as friends and are extracted by referring to the user information table stored in the user information storage unit 165.

User B who has seen this message is directed to User A who is participating in the group chat.
And so on. Here, “@User A” indicates that the message is for a specific user in the group chat (mention).

For example, the user A who visually recognizes this message
"You can print"
The chatbot receives this message, determines that there is permission from the user A who is registered as a friend, and responds to the print instruction from the user B that has been ignored. Run the print service.

In addition, from user B “@User A, please allow printing”
Even if a message permitting printing from a user other than the user A is transmitted, the chatbot does not execute the print instruction. However, if a message permitting printing is transmitted from a user C who is registered as a friend other than the user A, the chatbot may execute a print instruction. In a group chat,
“@User A, please allow printing”
This is because the user C who visually recognizes the message may permit the user A on behalf of the user A for some reason.

<Embodiment 5>
In the first to fourth embodiments, the print instruction from the user B who is not registered as a friend is ignored. However, the print instruction from the user B who is not registered as a friend may be suspended, and certain conditions are satisfied. The hold state may be released in the event of a failure.

  FIG. 10 shows a sequence diagram of the present embodiment.

  User A operates user terminal A to register a chatbot as a friend. The chat bot stores the user ID of the user registered as a friend in the user information table of the user information storage unit 165.

On the other hand, user B “prints” together with the manuscript.
When the message is sent to the chatbot, the chatbot extracts the user ID included in the message from the user B, and if it is determined that the user B is not a friend registered by referring to the user information table, The print service is not executed in response to the message automatically, and the “print” message is put on hold. “Print” from user B
Since the user A who is participating in the group chat is also visually recognized, the user A who has registered the chatbot as a friend while the print instruction is on hold is the “print” of the user B.
In response to the message
"OK"
When the message is sent and the print is permitted, the chat bot cancels the print instruction pending state of the user B by the message from the user A and executes the print service.

  Also in the present embodiment, the chat bot automatically responds to the message from the user B, holds it without executing the print service, and gives a print instruction by the message from the user A. Accordingly, it can be said that the print service is not executed.

  Note that while the print instruction is on hold, the chatbot maintains the print instruction on hold status even if there is a message to permit printing from a user who is not registered as a friend. If there is no message permitting printing from another user while the print instruction is on hold, the hold state is maintained as it is. However, when the hold state continues for a certain time, the chat bot may execute processing such as discarding the print instruction.

<Embodiment 6>
In the fifth embodiment, the user A who is registered as a friend permits the user B to print, but this permission can be performed while the user A visually recognizes the document included in the message of the user B.

FIG. 11 shows an example of a screen displayed on the display unit of the user terminal A while the chatbot is holding the print instruction from the user B. When the user A views or taps the message of the user B, the document 100 included in the message is displayed, and further, a message indicating whether printing is permitted or rejected in association with the document is transmitted. Button 102 is displayed. Button 102
"Print OK"
And "Print NG"
It consists of two buttons. In FIG. 11, a photograph is shown as the document 100, but it may be a message history in the group chat as described above.

  When the user A visually recognizes the document 100 displayed on the screen and determines that the document 100 can be printed, the user A operates a “print OK” button to transmit a print permission message. When it is determined that printing 100 is not appropriate, the “print NG” button is operated to reject printing.

  FIG. 12 shows an example of a screen displayed on the display unit of the user terminal A when a plurality of originals are included in the message of the user B. A plurality of originals 100 included in the message of the user B are displayed in a horizontal example, and a button 102 for transmitting a message indicating whether printing is permitted or rejected is displayed in association with each original 100. . The user A can select whether to permit or reject printing of each of the plurality of documents 100 by operating these buttons 102. For example, print permission is given for the first document, print rejection is given for the second document, and the like. The chat bot cancels only the hold state of the print instruction relating to the document that is permitted to be printed, and executes the print service.

  Note that the user B can visually recognize the print permission or rejection message for each original document from the user A in the group chat, and therefore can recognize that the user A has rejected the unprinted original document.

<Embodiment 7>
In the fifth embodiment, the chatbot puts the print instruction from the user B on hold, but may further notify the user in the group chat that the print instruction is on hold.

  FIG. 13A shows a sequence diagram of the present embodiment.

  User A operates user terminal A to register a chatbot as a friend. The chat bot stores the user ID of the user registered as a friend in the user information storage unit 165.

On the other hand, user B “prints” together with the manuscript.
When the message is sent to the chat bot, the chat bot extracts the user ID included in the message from the user B, and when the user B determines that the user is not registered as a friend, the chat bot automatically responds to the message and prints. The service is not provided and the “print” message is put on hold.

Next, the chat bot notifies the user in the group chat who has registered the chat bot as a friend that the print instruction from the user B is pending. Here, in the notification, when a message is individually sent by e-mail or the like only to users who are registered as friends (other users cannot see the message), for all users in the group chat There may be a case where it is transmitted and indicates a message directed to a specific user (other users can also visually recognize the message). In the latter case, for example, a chatbot
“@User A, please authorize printing”
And send a message to the group chat. Here, “Mr. @User A” indicates a message (mention) directed to a specific user A in the group chat as described above. Note that the individual notification may include notification to the user in a separate group of one-to-one with the chatbot.

In response to such a message, user A
"OK"
When the chat bot is permitted to print by sending a message such as “A”, the chat bot cancels the hold state of the print instruction of the user B by the message from the user A and executes the print service.

  Note that when a plurality of users are registered as friends, the chatbot may notify all of the plurality of users.

  FIG. 13B shows an example of a screen displayed on the display unit of the user terminal B.

  On the screen of the user terminal B, the chat service server 14 displays a representation figure (icon) 200 indicating the user B, an icon 202 indicating the user A, and an icon 204 indicating the chat bot. The messages 300 of the user A, the user B, and the chat bot are displayed in time series from the top to the bottom.

In FIG. 13B, user B first “prints” on the chatbot.
And send a message. A document as image data to be printed is transmitted together with the print instruction message.

The chat bot that has received this message holds the print instruction message because user B is a user who is not registered as a friend, identifies user A as a user who is registered as a friend,
"Hold print"
“@User A, please authorize printing”
Create a message and automatically respond.

Since this message is also visually recognized by user A in the group chat, user A responds to this message by saying “OK”.
And send a message.

The chatbot that received the message from user A cancels the hold of the print instruction,
"Start printing"
Is created and sent, and when printing is complete,
"Print completed"
Create a message with and send it.

  By visually recognizing the screen of FIG. 13B, the user B recognizes that the print service has been executed with the permission from the user A, and the user A has given the permission by the notification from the chatbot. It can be recognized that the print instruction of user B has been executed.

  The processing algorithm in the chatbot is described in detail as follows.

  Step 1: The chatbot registers the user A as a friend in response to a specific operation by the user A, that is, a button operation of “friend registration” designating a chatbot account, and stores the user ID of the user A in the user information table. .

  Step 2: When a message from user B is received, the content is analyzed, the user ID included in the message is extracted, the keyword “print” included in the content is extracted, and the message instructs printing. Interpret. With reference to the user information table, it is determined whether or not the user B is a user registered as a friend.

  Step 3: If the result of determination in step 2 is that the user B is a user registered as a friend, a print instruction is executed to provide a print service. If the user B is a user who is not registered as a friend, the user B is put on hold without executing a print instruction.

  Step 4: When the print instruction is suspended, the user registered as a friend is extracted with reference to the user information table. If another user participating in the group chat is registered as a friend (user A), the user is specified.

  Step 5: A message is created and transmitted to the user A identified in Step 4. After that, the system shifts to a reply waiting state from the user A.

  Step 6: An answer message from the user A is received, and it is analyzed whether the content is permission or rejection. If it is permitted, the print instruction that has been put on hold is canceled, the print is executed, and the print service is provided. If it is rejected, the hold status is not released. Even if an answer message from a user other than user A is received, the hold state is not released.

  Step 7: After providing the print service, create and send a print completion message.

FIG. 14 shows a case where user A and user C have registered chatbots as friends.
When the chatbot extracts the user ID included in the message from the user B and determines that the user B is not a friend, the chatbot automatically responds to the message and does not provide the print service. ”Message is put on hold.

Next, the chatbot notifies the user who has registered the chatbot as a friend that the print instruction from the user B is pending. In this case, as in the case of the previous message, when sending a message individually only to the user registered as a friend by e-mail etc. (other users cannot see the message), all in the group chat The message may be transmitted to the user and indicated to be a message directed to a specific user (other users can also view the message). For example, a chatbot
“Please allow printing for @User A and @User C”
And send a message to the group chat. In addition to the messages above, chatbots
“Please allow my friends and prints”
May be created and notified for group chat. Further, for example, the contents of the message may be changed sequentially so that the notification target spreads with time.

  In response to such a message, when the user A and the user C send a message such as “OK” to permit printing, the chatbot holds the print instruction of the user B by the message from the user A and the user C. Cancel the status and execute the print service.

Here, in the case where there are a plurality of users who are registered as friends, the condition for the chatbot to cancel the hold state of the print instruction from the user B is as follows:
(1) When one of a plurality of users registered as friends permits (2) When a majority of a plurality of users registered as friends permit (3) 2/3 of a plurality of users registered as friends (4) Any of the cases where all of a plurality of users registered as friends permit may be adopted. The condition may be adaptively changed according to the importance of the document included in the message from the user B. Alternatively, when there are a user who has permitted printing and a user who has refused printing, the printing instruction can be uniformly denied.

Moreover, in this embodiment, it is good also as the user who the user B specified as a user who notifies that the chat bot is on hold. For example, if user B wants permission from user C, “I want @user C's permission” to the chatbot.
And send a message. In response to this message, the chatbot
“@User C, please allow printing”
And send a message to the group chat.

<Eighth embodiment>
In the seventh embodiment, the chatbot notifies the user registered as a friend in the group chat. However, if there is no user registered as a friend in the group chat, the friend registration outside the group chat is registered. You may notify the user who is doing. Such a situation occurs when the user A who is registered as a friend, the user B who is not registered as a friend, and the chatbot are participating in the same group chat, and then the user A leaves the group chat for some reason. This can happen if

  FIG. 15 shows a sequence diagram of the present embodiment. It is assumed that the user D registers the chat bot as a friend but does not participate in the same group chat as the user B.

  When the chatbot extracts the user ID included in the message from the user B and determines that the user B is not a friend, the chatbot automatically responds to the message and does not provide the print service. ”Message is put on hold.

Next, the chatbot notifies the user who has registered the chatbot as a friend that the print instruction from the user B is pending. If there is no user who is registered as a friend in the same group chat, the user information table stored in the user information storage unit 165 is referred to and there is another user who is registered as a friend. Since the user D is not registered in the same group chat but has registered the chat bot as a friend, the chat bot
“@User B instructed to print this photo. Pending.”
Create a message and notify individually by e-mail. At this time, since the user D does not participate in the same group chat and cannot view the document transmitted from the user B, the document from the user B, that is, the service target is simultaneously notified together with this notification.

  In response to such notification, when the user D confirms the document and sends a message such as “OK” to the chat bot to permit printing, the chat bot issues a print instruction from the user B according to the message from the user D. Cancel the hold status and execute the print service.

Note that the chatbot may notify the user registered as a friend outside the group chat using a priority list of the notification destination. For example, priority is given to a user who participated in the group chat before, priority is given to a user who has a relatively large number of message exchanges with the user B, and so on. Of course, the user B may identify a user who is registered as a friend outside the group chat and send a message to the chatbot. For example,
"I want permission from @User D"
And so on.

<Ninth Embodiment>
In the seventh embodiment, the chatbot notifies the user who is registered as a friend in the group chat. However, even if it is notified to the user who is registered as a friend, the reply message is received within a certain time. If it is not possible to do so, it may be re-notified for a fixed number of times, or if it still cannot receive a response after re-notifying a predetermined number of times, the print instruction from user B is released and the print instruction is discarded. May be.

  FIG. 16 shows a sequence diagram of this embodiment.

User B prints along with the manuscript
When the message is sent to the chat bot, the chat bot extracts the user ID included in the message from the user B, and when the user B determines that the user is not registered as a friend, the chat bot automatically responds to the message and prints. The service is not provided and the “print” message is put on hold.

Next, the chatbot notifies the user who has registered the chatbot as a friend that the print instruction from the user B is pending. In this case, as in the case of the previous message, when sending a message individually only to the user registered as a friend by e-mail etc. (other users cannot see the message), all in the group chat The message may be transmitted to the user and indicated to be a message directed to a specific user (other users can also view the message). For example, a chatbot
“@User A, please authorize printing”
And send a message to the group chat.

In response to such a message, if the user A does not send any reply message within a certain time, the chat bot
"Please allow printing as soon as @User A"
Create a message and notify again.

Even in response to such a message, if the user A does not send any reply message within a certain time, the chat bot
“@User A, you will soon be disabled”
Create a message and notify again.

  If the chatbot cannot receive an answer message from the user A even if it is repeatedly notified a predetermined number of times, the chatbot cancels the print instruction from the user B and discards the print instruction. When the chat bot discards the print instruction, the chat bot may automatically respond to the notification of the discard to the user B.

Further, if the chatbot cannot receive an answer message from the user A even if it is repeatedly notified a certain number of times, the print instruction from the user B is pending for the user C who is registered as another friend. You may notify that there is. For example,
“@User C, please allow printing”
Or, “No response from @User A. @User C, please allow printing”
May be re-notified.

<Embodiment 10>
In the seventh embodiment, the chatbot notifies the user who is registered as a friend in the group chat. However, if the user explicitly refuses this notification without permitting the user, The print instruction may be canceled immediately after releasing the print instruction hold state.

  FIG. 17 shows a sequence diagram of this embodiment.

User B prints along with the manuscript
When the message is sent to the chat bot, the chat bot extracts the user ID included in the message from the user B, and when the user B determines that the user is not registered as a friend, the chat bot automatically responds to the message and prints. The service is not provided and the “print” message is put on hold.

Next, the chatbot notifies the user who has registered the chatbot as a friend that the print instruction from the user B is pending. For example, a chatbot
“@User A, please authorize printing”
And send a message to the group chat.

In response to such a message, user A
"not allowed"
Or "Print NG"
When the message is sent, the chatbot cancels the print instruction hold state from the user B and immediately discards the print instruction. When the print instruction is discarded, the chatbot may automatically respond to user B with a notification that the print instruction has been rejected by another user and that the print instruction has been discarded.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation is possible. Hereinafter, modified examples will be described.

<Modification 1>
In the embodiment, in response to a print instruction from user B who is not registered as a friend, the chat bot executes a print service when receiving a message from the user A who is registered as a friend to permit printing. However, the message indicating that printing is permitted from the user A can include not only an explicit permission message but also an implicit message. For example, the print service may be executed when the user A browses the hold notification from the chatbot or when a specific button indicating that the user has browsed is operated. The browsing includes the “read” state of the message.

<Modification 2>
In the embodiment, a print instruction from a user who does not register a chatbot as a friend is ignored or put on hold, but a print instruction from a user who is registered as a friend is put on hold and another user is registered as a friend When a print permission message is received from the printer, the hold state may be canceled and the print service may be executed. For example, when the user A gives an instruction to print the message history in the group chat and the user C permits this, the print instruction is canceled and the print service is executed.

<Modification 3>
In the embodiment, a chat bot that provides a print service according to a message from a user is described as an example of the chat bot, but the chat bot can provide any service other than this. Examples of these services are as follows.
・ Search service for music, news articles, accommodations, books, cooking recipes, etc. ・ Ticket reservation service ・ Exhibition / search / transaction communication service for flea market ・ Translation service to other languages

  FIG. 18 shows a system configuration diagram when the translation service is executed. Unlike FIG. 1, a translation engine A (19A) and a translation engine (19B) are provided instead of the printer A (18A) and the printer B (18B). The translation engine A is a software robot program that translates Japanese into English, and the translation engine B is a software robot program that translates Japanese into Chinese.

User A selects translation engine A, and sets and registers as a setting information a format that displays the original Japanese following the English translation. As a result, user A asks the chatbot, “Are you free today?”
The chatbot drives translation engine A and says "Are you free today?"
“Are you free today?”
And auto-respond messages.

  On the other hand, even if the user B who is not registered as a friend transmits a message to the chatbot, the chatbot does not provide a translation service by automatically responding to this message.

  FIG. 19 is a sequence diagram of a modified example. This is processing between the user terminal A operated by the user A, the user terminal B operated by the user B, and the chat bot. It is assumed that user A, user B, and chat bot exist in the same group chat, user A registers the chat bot as a friend, and user B does not register the chat bot as a friend.

  User A operates user terminal A to register a chatbot as a friend. The chat bot stores the user ID of the user registered as a friend in the user information storage unit 165.

  Next, user A sends a message to be translated to the chatbot. When the chatbot extracts the user ID included in the message from the user A and determines that the user A is a user registered as a friend, the chatbot automatically responds to the message and translates it with the translation engine associated with the user A. Run the service. For example, a Japanese message is translated into English and the user A is automatically answered.

  On the other hand, when the user B sends a message to be translated to the chatbot, the chatbot extracts the user ID included in the message from the user B, and determines that the user B is a user who is not registered as a friend. In response to the message, the translation service is not provided, and the translation message is ignored. Thereby, the user B cannot enjoy the translation service by a chat bot.

  Similar to the above embodiments, the chat bot can execute the translated message of the user B in response to a permission message from the user registered as a friend.

  FIG. 20 shows a sequence diagram in the case where the chatbot provides an accommodation facility search service.

  User A operates user terminal A to register a chatbot as a friend. The chat bot stores the user ID of the user registered as a friend in the user information table of the user information storage unit 165.

On the other hand, user B, along with the manuscript, “searches for a hotel”
When the message is sent to the chatbot, the chatbot extracts the user ID included in the message from the user B, and if it is determined that the user B is not a friend registered by referring to the user information table, The search service is not executed in response to the message automatically, and the “search for hotel” message is put on hold. “Search for hotels” from user B
Since the user A who participates in the group chat is also visually recognized, the user A who has registered the chatbot as a friend while the search instruction is on hold,
In response to the message
"OK"
When the search is permitted by sending a message such as “A”, the chatbot cancels the pending state of the search instruction of the user B by the message from the user A, and executes the search service in response to the search instruction.

10A user terminal A, 10B user terminal B, 10C user terminal C, 12 cloud, 14 chat service server, 16A bot server A, 16B bot server B, 18A printer A, 18B printer B.
