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) according to 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 executes the printing process by driving the printer A or the printer B according to setting information relating to the operation of the software robot program registered in advance for each user. 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 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 print commands to the printers A and B in accordance with commands 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 stores the received message 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 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 setting information items include, for example, identification information of a printer to be used, a color mode, a paper size, the number of copies, and the like, but are not limited thereto. The setting information can be determined according to the contents 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 functions as a storage unit, and stores a message from the user received by the message reception unit 161 as a history. In addition to storing all messages in the group chat, the message storage unit 167 starts message recording when a certain condition is satisfied, and ends message recording when another condition is satisfied. obtain.

  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. Further, the operation control unit 163 controls the start and end of the message recording operation in the message storage unit 167. That is, it controls which message is stored in the message storage unit 167 and when the message is stored in the message storage unit 167. Further, the operation control unit 163 reads and outputs the message stored in the message storage unit 167 in response to a request from the user. One of the output forms is printing by the printer A, but is not limited to this.

  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.

  FIG. 6 shows an example of a message management table stored in the message storage unit 167. In the case where a plurality of users, for example, user A, user B, and user C, form a group chat and perform a group chat, the operation control unit 163 transmits a message exchange (conversation) between users to the message storage unit 167. Control to memorize. When the message is stored in the message storage unit 167, it is stored together with its attribute information. The attribute information includes the user name and user ID of the message transmission source, the group name and group ID to which the user belongs, the date the message was transmitted, the message format (type), and the message content (content). . For example, when a text message is transmitted from the user A belonging to the X group, X is stored as the group name, the user A is the user name, the date, the text is the type, and the message content is stored. Even when a user in the group transmits a specific label or stamp instead of a message, the message is stored in the message storage unit 167 in the same manner as the message. In FIG. 6, the type of message from user C is “sticker”, which means that a specific label or stamp has been transmitted. The content of the stamp is specified as the ID (ID 1234) of the stamp. The meaning content of the stamp is uniquely determined by the stamp ID. For example, the stamp of ID 1234 is a stamp that instructs printing.

  The operation control unit 163 stores the message, stamp, and the like exchanged in the group chat in the message storage unit 167 together with the attribute. When there is a request from the user, the operation control unit 163 uses the attribute to send a message from the message storage unit 167. Is extracted and output.

  FIG. 7 schematically shows message storage processing and output processing of the present embodiment.

Assume that user A, user B, and user C form an X group, and when these users exchange messages and chat (chat), these messages are sent from chat service server 14 to bot server A ( 16A) and sequentially stored and accumulated in the message storage unit 167 of the bot server A (16A). Whether or not to store the message is controlled not by the chat service server 14 but by the bot server A. And, for example, user A “conversation history please” in the conversation
The message is supplied to the bot server A (16A) via the chat service server 14, and the bot server A analyzes the content of the message and accesses the message storage unit 167. The message storage unit 167 1 or a plurality of messages (conversation history) stored in. Specifically, the data is output to the printer A (18A) and printed, or output to the external mail server 19 and output in the mail transmission format. When the user information is stored in the user information storage unit 165 and the mail address of the user A is included as the user information, the conversation history is transmitted to the user A by transmitting mail to the mail address. Is provided.

User A can specify the output form. For example,
"Print conversation history"
The bot server A (16A) analyzes the message content, supplies the conversation history to the printer A (18A), and prints it out. Or
"Send conversation history by email"
The bot server A (16A) analyzes the message content, supplies the conversation history to the mail server 19 and prints it out.

  Next, the process between the user terminal, the chat bot, and the printer A will be described in more detail by taking print output by the printer A as an example of the output form of one or more stored messages (conversation history).

  FIG. 8 shows a sequence diagram of the user terminal A, the chat bot, and the printer A. As shown in FIG. 7, it is assumed that user A constitutes an X group with user B and user C. In addition, it is assumed that the user A operates the user terminal A to perform a specific operation (designate a chatbot account and operate a “friend registration” button) and register the chatbot as a friend. Here, friend registration refers to an operation for acquiring the authority to use a chatbot. The chat bot registers the user ID of user A in the user information table. Similarly, it is assumed that the user B and the user C operate the user terminal B and register a chatbot as a friend. The chat bot registers the user IDs of user B and user C in the user information table. Also, information indicating that user A, user B, and user C constitute the same group is registered.

  First, user A invites a chat bot in a group chat formed by user A, user B, and user C. The invitation is executed, for example, when the user A operates a specific button (invitation button) displayed on the user terminal A and transmits a specific command or mail to the chat bot.

In response to this invitation, the chatbot participates in the group chat, and in response to participating in the group chat,
"Do you want to record the conversation?"
And respond with a message.

User A who has visually recognized this message receives “Yes” from user terminal A.
The chat bot analyzes the content of this message and, in response to a positive answer, sends a message exchange in the group chat thereafter (conversation) to the message storage unit. 167 sequentially recorded. The recorded message includes attributes as shown in FIG. 6 and includes text, labels, stamps, images, sounds, and the like.

Next, the user terminal A requests the chat bot to leave the group chat at an arbitrary timing. The chatbot then leaves the group chat in response to the exit request,
"Do you want to print the conversation?"
And respond with a message.

User A who has visually recognized this message receives “Yes” from user terminal A.
When a positive message is transmitted, the content of this message is analyzed, and if it is a positive response, recording of the subsequent messages is terminated and the message stored in the message storage unit 167 is read. Then, print data (conversation history data) is created, the data is attached to the printer A, and a print instruction is output.

  Printer A prints the data (conversation history data) in response to a print instruction from the chatbot. The print output form is determined by the setting information. When the printer A completes printing, it returns a print completion notification to the chatbot.

  With the above processing, all messages from when the chat bot joins the group chat until it exits are recorded, and the message is printed out from the printer A as a conversation history in response to a request from a user configuring the group. Is done. Participation in the group chat and exit from the group chat are caused by the specific operation of the user terminals constituting the group, and thus it can be said that the start and end of message recording are controlled according to the specific operation of the user terminals.

In FIG. 8, after joining the group chat,
"Do you want to record the conversation?"
The message recording is started when a positive answer is transmitted from the user terminal A in response to this, and the message recording is started in response to the participation in the group chat. May start.

Also, if you leave after receiving an exit request,
"Do you want to print the conversation?"
The message recording may be terminated simultaneously with leaving.

<Embodiment 2>
In Embodiment 1, a message when a chatbot joins a group chat “Do you want to record a conversation?”
In response to “Yes” from user terminal A
In addition to this, if the message from the user terminal is a specific message, the message recording may be started in response to the specific message. Good. Whether or not the message is a specific message can be determined by whether or not a predetermined keyword, symbol, mark, or the like is included. In short, the chat bot can control the start and stop of message recording in response to transmission of a specific message from a user in a group chat. This allows you to switch between recording start and recording stop regardless of sending a specific message in group chat, for example, preparing a recording mode and a non-recording mode as chatbot modes, and switching these modes separately from message sending Compared to the above, it is possible to easily control the start and stop of message recording.

  FIG. 9 shows a sequence diagram of the user terminal A, chat bot, and printer A in the present embodiment. Similarly to FIG. 8, it is assumed that the user A or the like has registered a chatbot as a friend and has the authority to use the chatbot.

  First, user A invites a chat bot in a group chat formed by user A, user B, and user C.

  The chat bot participates in the group chat in response to this invitation. In the state of participating in the group chat, an automatic response is made in response to a message from the user terminal A, and a print service such as image data transmitted from the user terminal A is executed as appropriate.

On the other hand, at an arbitrary timing from the user terminal A,
“Let's decide the policy of this activity”
Message is sent.

The chat bot analyzes the content of this message and determines whether or not a predetermined keyword is included. Pre-defined keywords
"policy"
"Let's decide"
"Let's decide"
"Determine"
And so on, it is determined that the message is a specific message because these keywords are included, and the chat bot determines that the transmitted message is the specific message (first specific message), and records subsequent messages. To start.

  Thereafter, when messages are exchanged between users constituting the group, these messages are sequentially recorded and accumulated.

Next, from the user terminal A at an arbitrary timing, “Now, the policy is determined by ...”
Message is sent.

The chat bot analyzes the content of this message and determines whether or not a predetermined keyword is included. Pre-defined keywords
"policy"
"Decision"
"Let's decide"
"decided"
"Decision"
And so on, it is determined that the message is a specific message because these keywords are included, and the chatbot terminates the message recording on the assumption that the transmitted message is the specific message (second specific message). .

Next, “Print” from user terminal A
, The chatbot parses the content of this message,
"Yes"
The message stored in the message storage unit 167 is read to create print data (conversation history data), and the print data is attached to the printer A with the data attached. Is output.

  Printer A prints the data (conversation history data) in response to a print instruction from the chatbot. When the printer A completes printing, it returns a print completion notification to the chatbot.

  With the above processing, in a state where the chat bot participates in the group chat, all messages from when the first specific message is transmitted from the user terminal to when the second specific message is transmitted are recorded, and the user is recorded. In response to a request from the printer A, the message is printed out from the printer A as a conversation history.

  The keyword may be set in advance by any user who configures the group, or may be set by the administrator of the chat service. The keyword may be fixed, and may be added or deleted as appropriate. Furthermore, the user may set a keyword as one of the setting information.

  In FIG. 9, the message recording start and recording end are controlled in accordance with the message being a specific message, but the message recording start and recording end may be controlled in accordance with a specific stamp.

  For example, recording may be started by transmitting a stamp of a symbolic figure (icon) of recording, and recording may be terminated by transmitting a stamp of an icon of recording stop.

Further, when the message is the first specific message, the subsequent message recording is started. At this time, the attribute of the message to be recorded by the first specific message may be designated. For example, the user A operates the user terminal A to “determine a policy for this activity.
Record the conversation between A and B "
The chat bot records only the message from the user terminal A and the message from the user terminal B among the subsequent messages. Even if a message from the user terminal C constituting the X group is included, it is excluded from recording.

Further, when the “important” flag can be set as the message attribute, the user A operates the user terminal A to “determine the policy of this activity.
Log only important messages "
When the message is transmitted, the chat bot records only the messages to which the flag of “important” is added among the subsequent messages. Even if the message from the user terminal B includes a message to which no important flag is added, it is excluded from recording.

In addition, the user A operates the user terminal A to “determine a policy for this activity.
Record only today's message "
, The chat bot records only messages sent during the current day among the subsequent messages.

Further, the user A operates the user terminal A to “determine a policy for this activity.
Record only messages that contain the text *** ”
When the message is transmitted, the chat bot records only the message including the character string “***” among the subsequent messages.

  In short, the user can appropriately select a message to be stored in the message storage unit 167 by designating the attribute of the message.

<Embodiment 3>
In the first and second embodiments, all the messages recorded in the message storage unit 167 are output. However, among the messages recorded in the message storage unit 167, only a desired message requested by the user may be output. Good.

  FIG. 10 shows a sequence diagram of the user terminal A, the chat bot, and the printer A in the present embodiment. Similarly to FIG. 8, it is assumed that the user A or the like has registered a chatbot as a friend and has the authority to use the chatbot.

  First, user A invites a chat bot in a group chat formed by user A, user B, and user C.

In response to this invitation, the chatbot participates in the group chat, and in response to participating in the group chat,
"Do you want to record the conversation?"
And respond with a message.

User A who has visually recognized this message receives “Yes” from user terminal A.
The chat bot analyzes the content of this message and, in response to a positive answer, sends a message exchange in the group chat thereafter (conversation) to the message storage unit. 167 sequentially recorded. The stored message includes attributes as shown in FIG. 6 and includes text, labels, stamps, images, sounds, and the like.

Next, the user A operates the user terminal A at an arbitrary timing,
"Print only Mr. A's text"
And "Print only important text"
And send a message. That is, the user A requests not only all messages stored in the message storage unit 167 but only “Mr. A”, that is, the message of the user A and important messages. “Mr. A” or “important” is a message attribute, and the user A specifies and requests these attributes.

The chatbot that receives this message analyzes the content of the message,
"Print only Mr. A's text"
Is extracted from the message stored in the message storage unit 167, the message from the user A, that is, the message from the user A, and the message having the attribute “important” is extracted from the message. To do. The attribute of “important” may be added by the user himself / herself who transmitted the message, or may be automatically added by the chatbot analyzing the message content. For example, when a specific keyword is included, it is determined as “important” and an attribute is added. For example, the importance of the message may be classified into three levels (usually important and most important), and the important and most important messages may be extracted.

After extracting user A's message and “important” message, the chatbot counts the number of extracted messages,
“○ will print. Are you sure?”
And respond with a message.

User A who has visually recognized this message receives “Yes” from user terminal A.
If you send a positive message to, the content of this message is parsed, and in response to a positive response, print data (part of the conversation history data) is created from the extracted message, The data is attached to the printer A and a print instruction is output.

  Printer A prints the data (part of conversation history data) in response to a print instruction from the chatbot. When the printer A completes printing, it returns a print completion notification to the chatbot.

  As a result of the above processing, only messages that match the request from the user terminal A among the messages recorded in the message storage unit 167, that is, important messages out of the messages from the user terminal A are printed out from the printer A. .

In FIG. 10, the user terminal A “prints only the text of Mr. A”
"Print only important text"
However, a message including a specific character string may be requested. For example,
“Print only text that contains the string ***”
