The three communication terminals 9A, 9B and 9C constitute a group, and for example, when the communication terminal 9A transmits a message to the group, processing for transmitting the message to the communication terminals 9B and 9C is performed.

  The server 100 receives the message transmitted by the communication terminal 9 and transmits the message to the communication terminal 9 corresponding to the transmission destination of the message. Furthermore, the server 100 receives the information on the operation instruction received by the communication terminal 9 from the user, and performs processing according to the content of the instruction. The network N is, for example, the Internet or the like, and is a computer network to which a plurality of communication terminals and computers are connected.

  FIG. 2 is a block diagram showing an internal configuration of the server 100. As shown in FIG. The server 100 includes a control unit 110, a storage unit 120, a communication unit 130 (reception unit), and the like.

  The control unit 110 includes a processor, a random access memory (RAM), a read only memory (ROM), and the like. The processor is a central processing unit (CPU), an MPU, an ASIC, or the like. The control unit 110 functions as a control unit 111, a transmission destination selection unit 112, a keyword detection unit 113, and a summary unit 114 when the processor executes a control program stored in a ROM or the like. Note that each of the above-described units of the control unit 110 may be configured by hardware circuits regardless of the operation based on the control program.

  The control unit 111 is responsible for overall operation control of the server 100. The transmission destination selection unit 112 restricts and selects the communication terminal of the transmission destination of the message received by the communication unit 130. The keyword detection unit 113 detects a keyword included in the message received by the communication unit 130. The summary unit 114 extracts keywords from the message received by the communication unit 130, and creates a summary of the message.

  The storage unit 120 is, for example, an HDD or the like, and stores programs and data necessary for the operation of the server 100. Furthermore, the storage unit 120 includes a keyword transmission history storage unit 121. The keyword transmission history storage unit 121 stores, for each communication terminal 9, the transmission history of the keyword included in the message transmitted by each communication terminal 9.

  The communication unit 130 includes a communication module and the like, and transmits and receives various data to and from a computer, the communication terminal 9, and the like on the network N connected to the communication unit 130.

  FIG. 3 is a block diagram showing an internal configuration of the communication terminal 9. The communication terminal 9 includes a control unit 910, an input receiving unit 920, a display unit 930, a storage unit 940, a communication unit 950, and the like.

  Control unit 910 is configured of a processor, a RAM, a ROM, and the like, and controls the overall operation control of communication terminal 9 by an operation according to a program stored in storage unit 940, for example. The input receiving unit 920 receives an input operation from the user. The display unit 930 is a monitor that displays characters and images. The storage unit 940 is made of, for example, a non-volatile memory.

  The messaging application is application software for performing message exchange (chat) with other communication terminals in real time. The messaging application also executes processing for exchanging messages between a plurality of communication terminals forming a group (group chat).

  In the message exchange using such a messaging application, although the conversation within the group continues, the conversation unrelated to me continues and all are displayed on the display of the own communication terminal, the relationship to the conversation concerned Users who do not have can feel bothersome. In addition, important messages needed for me could be buried in messages unrelated to me and overlooked.

  Therefore, a method in which the user can confirm only a necessary message on the display unit by selecting the transmission destination of the message by selecting the transmission destination of the message is divided into first to fifth embodiments.

First Embodiment
The first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram in which messages received from the communication terminals 9A, 9B and 9C forming the group by the server 100 are displayed in time series. Although the message is shown in a balloon in FIG. 4, in actuality, the server 100 manages the message as simple text data, and is shown in a balloon for easy understanding of the explanation.

  Also, alphabets "A", "B" and "C" on the left side of the balloon indicate user names. Hereinafter, the user name of the communication terminal 9A is "A", the user name of the communication terminal B is "B", and the user name of the communication terminal 9C is "C". The messages m1 and m2 are messages transmitted from the communication terminal 9C of the user name "C". The next message m3 is a message transmitted from the communication terminal 9A of the user name "A". The time shown on the left side of the user name is the time when each message was transmitted from each communication terminal. That is, it is assumed that chat is performed by each user of user name "A", user name "B", and user name "C" (hereinafter, the same applies to each embodiment).

  FIG. 5 is a view showing an example of a screen displayed on the display units of the communication terminals 9A, 9B and 9C when the message shown in FIG. 4 is transmitted from each communication terminal 9. 930A indicates a display unit of the communication terminal 9A, 930B indicates a display unit of the communication terminal 9B, and 930C indicates a display unit of the communication terminal 9C. The messages displayed to the right of each display unit are messages transmitted from its own communication terminal. For example, among the messages displayed on the display unit 930A, the message m3 to the right is a message transmitted by the communication terminal 9A.

  And the message currently displayed on the left of each display part is a message which the other communication terminal 9 transmitted. For example, the left side messages m1, m2 and m4 displayed on the display unit 930A are messages transmitted from the communication terminal 9C.

  Return to FIG. When the messages as shown in FIG. 4 are sequentially transmitted from the communication terminals 9A, 9B and 9C and received by the server 100, the messages m1 to m4 are conversations between the user A and the user C, and the messages m6 to m9 are with the user B It is a conversation of user C. That is, although belonging to the same group, the messages m1 to m4 may be conversations not necessary for the user B, and the user B is bothersome by displaying these messages on the communication terminal 9B. You may feel.

  Furthermore, the messages m6 to m9 may be conversations that are not necessary for the user A, and the user A may feel troublesome when these messages are displayed on the communication terminal 9A.

  Therefore, the transmission destination selection unit 112 of the server 100 selects the communication terminal of the user indicated by the user name as the transmission destination for the message starting with the user name and the subsequent transmitted messages, and the communication unit 130 selects the communication terminal. Send the message to the specified destination. The communication unit 130 does not transmit the message except for the selected transmission destination except for the sender of the message. For this reason, each user can receive only the message addressed to himself without receiving the message addressed to others.

  The flow of processing will be described. As shown in FIG. 4, in the server 100, when the communication unit 130 receives the message m1 from the communication terminal 9C, the transmission destination selection unit 112 registers personal information such as a user name (eg, registered in a group) at the beginning of the message. It is searched whether the user name of the existing communication terminal, that is, the user names "A", "B" and "C" are included. When detecting the personal information such as the user name, the transmission destination selection unit 112 selects the communication terminal that is the transmission source of the message and the communication terminal of the user name as the transmission destination of the message. As personal information, there are other names (nicknames), telephone numbers, identification numbers (ID numbers), etc. used only on the messaging application.

  At the beginning of the message m1, the user name “A” of the communication terminal registered in the group is included. Therefore, the transmission destination selection unit 112 restricts the transmission destination of the message m1 to the communication terminal 9C that is the transmission source of the message m1 and the communication terminal 9A of the user A. The control units 910 of the communication terminals 9A and 9C cause the display unit to display the received message. That is, at least the exchange of the messages m1, m2, m3 and m4 is displayed only on the display parts of the communication terminals 9A and 9C.

  As shown in FIG. 5, the messages m1 to m4 are displayed on the display unit 930A and the display unit 930C. However, since the transmission destination selection unit 112 has not selected the communication terminal 9B as the transmission destination of the messages m1 to m4, the communication unit 130 does not transmit the messages m1 to m4 to the communication terminal 9B. Therefore, the messages m1 to m4 are not displayed on the display unit 930B.

  In addition, when the exchange of the message in the group is not performed for a predetermined time (here, 5 minutes will be described as an example), the transmission destination selection unit 112 concludes that the conversation has been exchanged. Judge and release the restrictions on the destination of the message.

  That is, since the transmission time of the message m4 is 10:06 (10: 6) and there is no transmission of the message for 5 minutes or more, the transmission destination selection unit 112 cancels the restriction on the transmission destination of the message. Therefore, the message m5 transmitted at 10:20 (10:20) is transmitted to all the communication terminals 9A, 9B and 9C in the group.

  At the beginning of the message m6 transmitted next, the user name "B" of the communication terminal registered in the group is included. Therefore, the transmission destination selection unit 112 selects the transmission destinations of the message m6 and the messages after the message m6 as the communication terminal 9C that is the transmission source of the message m6 and the communication terminal 9B of the user B. The control unit 910 of each of the communication terminals 9B and 9C causes the display unit to display the received message. That is, at least the exchange of the messages m6 to m9 is displayed only on the display units of the communication terminals 9B and 9C.

  That is, as shown in FIG. 5, the messages m6 to m9 are sequentially displayed on the display unit 930B and the display unit 930C. However, since the transmission destination selection unit 112 does not designate the communication terminal 9A as the transmission destination of the messages m6 to m9, the communication unit 130 does not transmit the messages m6 to m9 to the communication terminal 9A. That is, the messages m6 to m9 are not displayed on the display unit 930A.

  As described above, the transmission destination selection unit 112 of the server 100 selects the communication terminal of the user indicated by the user name and the communication terminal of the transmission source of the message for the message starting with the user name and the subsequent messages. Then, the communication unit 130 transmits the message to the selected transmission destination. As a result, since a message addressed to another person is not displayed on the communication terminal of each user, it is possible to eliminate the inconvenience of displaying unnecessary messages.

Second Embodiment
The second embodiment will be described with reference to FIGS. FIG. 6 is a diagram in which messages received from the communication terminals 9A, 9B and 9C forming the group by the server 100 are displayed in time series. FIG. 7 is a view showing an example of a screen displayed on the display units of the communication terminals 9A, 9B and 9C when the message shown in FIG. 6 is transmitted from each communication terminal 9.

  This will be described using FIG. When the communication unit 130 of the server 100 receives the message m11 from the communication terminal 9, the keyword detection unit 113 searches for a keyword from the message. The keywords are determined in advance and stored by the keyword detection unit 113. For example, words frequently used in business communication such as "document", "deadline", "meeting", "business trip", "vacation", etc. These are words often used in school life such as class, report, homework, club activities and so on. The user may be able to additionally register any keyword.

  For example, when the words “original” and “deadline” are detected from the message m11, the keyword detection unit 113 causes the keyword transmission history storage unit 121 to store the keywords transmitted by the communication terminal 9C that is the transmission source of the message m11. Furthermore, the transmission destination selection unit 112 detects, from the keyword transmission history storage unit 121, communication terminals that have transmitted the words "original" and "deadline" in the past.

  FIG. 8 is a diagram showing an example of the data configuration of the keyword transmission history storage unit 121. As shown in FIG. The keyword transmission history storage unit 121 stores keywords transmitted in the past for each communication terminal. The transmission destination selection unit 112 detects the communication terminal 9A as a communication terminal that has transmitted "document" and "deadline" in the past.

  Therefore, the transmission destination selection unit 112 selects the communication terminal 9C that is the transmission source of the message m11 and the communication terminal 9A that has transmitted the keyword included in the message m11 as the transmission destination of the message.

  As shown in FIG. 7, the messages m11 to m13 are displayed on the display unit 930A and the display unit 930C. However, since the transmission destination selection unit 112 has not selected the communication terminal 9B as the transmission destination of the messages m11 to m13, the communication unit 130 does not transmit the messages m11 to m13 to the communication terminal 9B. Therefore, the messages m11 to m13 are not displayed on the display unit 930B.

  As described above, each communication terminal displays only a message regarding a keyword that has been transmitted in the past. That is, for the user who is the owner of each communication terminal, the exchange of messages likely to be related to him / her is displayed, but the other messages are not displayed. Therefore, the user does not feel the inconvenience of displaying unnecessary messages.

  In addition, when the exchange of messages in the group is not performed for a predetermined time or more, the transmission destination selection unit 112 determines that the conversation which has been exchanged is ended, and releases the restriction on the transmission destination of the message. . That is, although the transmission destination selection unit 112 restricts the transmission destinations of the messages transmitted after the message m11 to the communication terminals 9A and 9C, the time interval of the messages is longer than a predetermined time (for example, 5 minutes) If not, the transmission destination selection unit 112 cancels the restriction on the transmission destination of the message. That is, the transmission destination selection unit 112 cancels the restriction on the transmission destination after a predetermined time after the transmission of the message m13.

  Return to FIG. Next, the keyword detection unit 113 searches the message m14 for a keyword. For example, when the keyword detection unit 113 detects the word “meeting” from the message m14, the keyword detection history storage unit 121 stores the word as a keyword transmitted by the communication terminal 9C that is the transmission source of the message. Furthermore, the transmission destination selection unit 112 detects, from the keyword transmission history storage unit 121, a communication terminal that has transmitted the word "meeting" in the past.

  The transmission destination selection unit 112 detects the communication terminal 9B as a communication terminal that has transmitted the keyword "meeting". Therefore, the transmission destination selection unit 112 selects, as the transmission destination of the message, the communication terminal 9C that is the transmission source of the message m14 and the communication terminal 9B that has transmitted the keyword included in the message m14.

  As shown in FIG. 7, the messages m14 to m17 are displayed on the display unit 930B and the display unit 930C. However, since the transmission destination selection unit 112 has not selected the communication terminal 9A as the transmission destination of the messages m14 to m17, the communication unit 130 does not transmit the messages m14 to m17 to the communication terminal 9A. Therefore, the messages m14 to m17 are not displayed on the display unit 930A.

  Thus, the transmission destination selection unit 112 selects the communication terminal that has transmitted the keyword included in the message and the communication terminal of the transmission source of the message as the transmission destination, and the communication unit 130 selects the selected transmission destination. Send a message to As a result, for the user who is the owner of each communication terminal, messages related to him / her are delivered to the communication terminal of each user, but other messages are not delivered. Therefore, the user can eliminate the inconvenience of displaying unnecessary messages.

Embodiment 3
The third embodiment will be described with reference to FIGS. 9 and 10. FIG. 9 is a diagram in which messages received from the communication terminals 9A, 9B and 9C forming the group by the server 100 are displayed in time series. FIG. 10 is a view showing an example of a screen displayed on the display units of the communication terminals 9A, 9B and 9C when the message shown in FIG. 9 is transmitted from each communication terminal 9.

  As shown in FIG. 9, the user A and the user C exchange messages m21 to m29 for 10 minutes. As described above, when only two users, user A and user C, exchange messages in a short time, the content of the exchange is likely to be content that is not related to user B.

  Therefore, when the message exchange between only the user A and the user C is repeated within a predetermined time (for example, within 3 minutes), the transmission destination selection unit 112 communicates the transmission destination of the subsequent messages to the user A. Terminal 9A and user C's communication terminal 9C.

  At the time of receiving the message m21, the transmission destination selection unit 112 sets the transmission destinations to the communication terminal 9A, the communication terminal 9B, and the communication terminal 9C, which are all the communication terminals in the group. Thereafter, since the message exchange between the communication terminal 9A and the communication terminal 9C is repeated (messages m21 to m24), when the server 100 receives the message m25, the transmission destination selection unit 112 selects the transmission destination of the message m25 and thereafter. It limits to 9 A of communication terminals, and 9 C of communication terminals. That is, although the messages m25 to m29 are transmitted to the communication terminal 9A and the communication terminal 9C, they are not transmitted to the communication terminal 9B.

  Therefore, as shown in FIG. 10, although the messages m21 to m24 are displayed on the display unit 930B, the messages m25 and after are not displayed. In this way, although message exchanges that are likely to be related to the user are displayed, other messages are not displayed, and the user does not feel bothered of displaying unnecessary messages.

  In addition, when the exchange of the message in the group is not performed for a predetermined time (for example, 5 minutes) or more, the transmission destination selection unit 112 determines that the conversation exchanged is completed, and the transmission destination of the message is Release the restriction.

Fourth Embodiment
The fourth embodiment will be described. FIG. 11A is a diagram showing an example of a screen displayed on the display unit 930B of the communication terminal 9B when the message shown in FIG. 9 is transmitted from each communication terminal 9. FIG. 11B is a diagram showing an example of a screen displayed on the display unit 930B of the communication terminal 9B with the chat contents omitted.

  When a chat is being performed by the user A, the user B, and the user C, the display unit of each communication terminal 9 displays the notification stop button 91 (FIG. 11A shows an example of the display state of the display unit 930B of the communication terminal 9B. Shown). When the user presses or touches the notification stop button 91, the communication unit 950 of the communication terminal 9 transmits a signal indicating that the button is selected to the server 100. When the communication unit 130 of the server 100 receives a signal indicating that the notification stop button 91 is selected, the transmission destination selection unit 112 excludes the communication terminal that is the transmission source from the transmission destination of the message.

  For example, when a message as shown in FIG. 11A is exchanged between user A and user C, and the content is displayed on display unit 930 of communication terminal 9B of user B, user B is exchanged. If it is determined that the content of the message is not necessary, an operation to select the notification stop button 91 is performed. In response to this selection operation, the communication unit 950 of the communication terminal 9B transmits a signal indicating that the notification stop button 91 has been selected to the server 100. When the communication unit 130 of the server 100 receives this signal, the transmission destination selection unit 112 removes the communication terminal 9B from the message transmission destination from the message (for example, the message m25) immediately after receiving the signal.

  When message exchange within the group has not been performed for a predetermined time (for example, 5 minutes), the restriction on the transmission destination of the message is released.

  As described above, by selecting the notification stop button 91, since the message not related to oneself is not displayed on the screen, the user does not feel the inconvenience of displaying the unnecessary message.

  While the transmission destination selection unit 112 has excluded the communication terminal B as the transmission destination of the message by the user B touching the notification stop button 91, the number of messages transmitted within the group is displayed as a comment 92 Or (FIG. 11B). When the user touches the comment 92, the communication unit 950 of the communication terminal 9B transmits a request signal to the server 100, and in response to this signal, the server 100 transmits a message which has not been transmitted to the communication terminal 9B. Alternatively, the communication unit 950 of the communication terminal 9B may receive the messages collectively, and the control unit 910 may display these messages on the display unit 930. By doing this, the user B can view the message that has stopped notifying later. In addition, it is applicable also to the said Embodiment 1-3.

Fifth Embodiment
In the first to fourth embodiments, the method of transmitting the message only to the communication terminal 9 which may require the display of the message has been described. However, some users do not need to display the message exchange, but may want to know the final conclusion. In the fifth embodiment, a method of displaying a summary of message exchange will be described.

  The fifth embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram in which messages received from the communication terminals 9A, 9B and 9C forming the group by the server 100 are displayed in time series. FIG. 13 is a diagram showing an example of a screen displayed on the display units of the communication terminals 9A, 9B and 9C when the message shown in FIG. 12 is transmitted from each communication terminal 9.

  As shown in FIG. 12, the user A and the user C exchange messages m31 to m39 in 10 minutes. Thus, when only the user A and the user C exchange messages, the user B may want to know only the conclusion of the exchange, even if he does not participate in the conversation and does not want to look at the contents of the conversation.

  Thus, the summary unit 114 detects keywords from the message and summarizes the content of the exchanged message. For example, the summary unit 114 creates a summary by putting together the answers to the question message.

  The summary unit 114 searches for a keyword or a question from the message transmitted by the communication terminal 9. The summary unit 114 detects a question sentence by, for example, searching for a question mark "?" In the message. Further, the summary unit 114 detects an answer to the question sentence by searching for a keyword from the message.

  Keywords are predetermined, and for example, words often used in business communication such as "script", "deadline", "meeting", "business trip", "vacation", "class", "report", " It includes words frequently used in school life such as homework, club activities, etc., as well as words related to schedules such as places and dates. The user may be able to additionally register any keyword.

  First, when the communication terminal 9C transmits the message m31, the summary unit 114 determines whether the message m31 is a question sentence and detects a keyword. The summary unit 114 detects a question mark from the message m31 to determine that it is a question sentence, and further extracts a keyword. For example, from the message m31, the characters "Tomorrow's meeting" are extracted.

  Subsequently, the summarizing unit 114 extracts the text "General affairs department meeting" from the message m33, "10 o'clock" from the message m37, and "the place is the first meeting room" from the message m38. The summary unit 114 creates a sentence in which these keywords are summarized as a summary sentence.

  As shown in FIG. 13, the messages m31 to m39 are displayed on the display unit 930A and the display unit 930C. Since the messages m31 to m39 are exchanged only by the two users A and C, the transmission destination selection unit 112 uses the method of any of the first to fourth embodiments for the communication terminal 9B. The communication terminal B is excluded from the destination of the message. That is, the exchange of the message m35 and thereafter is not transmitted to the communication terminal B, and is not displayed on the display unit 930B.

  Then, after the exchange of the messages of the user A and the user C is completed, the summary unit 114 transmits the created summary to the communication terminal 9 B which has been excluded as the transmission destination during the exchange of the message.
