Returning to
The communication interface 160 transmits data from the CPU 110 to other devices such as the communication terminal 300 of the user and the communication terminal 200 of the person in charge of answering the question, via the Internet, the carrier network, the router, or the like. Conversely, the communication interface 160 receives data from the other device, such as the communication terminals 300 and 200, via the Internet, the carrier network, the router, or the like, and sends the data to the CPU 110.
Information processing in the server 100 according to the present embodiment will be described below. Note that, for the purpose of description, a form of the server 100 will be described below in which the single server 100 achieves a function of the chatbot for automatically conducting a chat with the user and a function of operating the business chat used by the person in charge of answering the question. However, both of the functions may be implemented by separate devices, or may be implemented by more than two devices. As illustrated in
First, the CPU 110 of the server 100 accepts an inquiry from the communication terminal 300 of the user via a website, for example, using the communication interface 160 (step S102).
The CPU 110 refers to the FAQ data 121 to determine whether it is possible to automatically answer the inquiry using the chatbot (step S104). If not possible, the CPU 110 performs the processing from step S110.
If possible, the CPU 110 creates an answer using the chatbot with reference to the FAQ data 121, and transmits the answer data to the communication terminal 300 via the communication interface 160 (step S106).
The CPU 110 queries the communication terminal 300 about whether the problem has been resolved, via the communication interface 160 (step S108). If the problem has been resolved, the CPU 110 terminates the processing relating to the question and answer at this time, and waits for the next inquiry from the communication terminal 300.
If the problem has not been resolved (NO at step S108), the CPU 110 determines whether the prescribed condition is satisfied (step S110). Then, when the prescribed condition is satisfied, the CPU 110 accepts information regarding whether the user wants to have the live human chat. Note that, here, examples of the prescribed condition include a case in which the chatbot has provided the answer three times or more, a case in which the inquiry has been made by a specific user, a case in which a matching rate to the questions stored in the FAQ data 121 is significantly low, and the like.
If the prescribed condition is not satisfied, or if the user does not want to have the live human chat (NO at step S110), the CPU 110 may request, via the communication interface 160, the communication terminal 300 to change wording of the question, and repeats the processing from step S102.
If the prescribed condition is satisfied, or if the user wants to have the live human chat (YES at step S110), the CPU 110 extracts the person in charge appropriate for answering the question from the user (step S112). For example, the CPU 110 identifies the identification information about the operation relevant to the most recent question by referring to the FAQ data 121, and extracts the person in charge to whom the relevant operation is assigned, by referring to the person-in-charge data 122.
The CPU 110 refers to the person-in-charge data 122 to confirm whether the status of the person in charge is “present,” or queries the communication terminal 200 of the person in charge, via the communication interface 160, as to whether the person in charge is available (step S114).
If the person in charge is unable to respond (NO at step S116), via the communication interface 160, the CPU 110 informs the communication terminal 300 of the user who has made the inquiry this time that the person in charge will contact the user later (step S120). Note that at this time, the CPU 110 may query the communication terminal 300 of the user about contact information of the user, via the communication interface 160. Then, the CPU 110 may provide the contact information for the communication terminal 200 of the person in charge of answering the inquiry.
When the person in charge is available (YES at step S116), via the communication interface 160, the CPU 110 requests the person in charge to respond to the user in person using the business chat (step S122). When the person in charge rejects the request to respond via the communication terminal 200 (NO at step S124), the CPU 110 performs the processing at step S120.
When the person in charge declares his/her participation in the business chat in order to provide the answer to the user via the communication terminal 200 (YES at step S124), via the communication interface 160, the CPU 110 provides the communication terminal 200 with a chat history regarding the question concerned between the user and the chatbot (step S126). The communication terminal 200 receives the chat history, and the information is displayed on the display 230 (step S128).
Note that, in the present embodiment, via the communication interface 160, the CPU 110 of the server 100 causes exchanges of messages between the user and the chatbot to be displayed on a screen of the business chat of the communication terminal 200, to make it seem as if the user and the person in charge of answering the question have been having a chat.
As a function of the business chat, via the communication interface 160, the CPU 110 of the server 100 starts a chat between the user of the communication terminal 300 and the live human person in charge of answering the question via a website or the like (step S132), while starting a chat between the person in charge of answering the question and the user via the communication terminal 200 (step S130), as illustrated in
Note that, in the embodiment described above, at step S112 illustrated in
For example, the memory 120 of the server 100 may store identification information of an overall person in charge who responds to the user when the appropriate person in charge associated with all of a plurality of the questions answered by the chatbot, cannot be found. Then, when the prescribed condition is satisfied, and if the user wants to have the live human chat, the CPU 110 searches for the person in charge who is knowledgeable about all the questions made to the chatbot. Then, when the person in charge who is knowledgeable about all the questions made this time cannot be found, the CPU 110 may start the live human chat using the overall person in charge.
Alternatively, at step S112 illustrated in
In the embodiments described above, the user and the advisor conduct the chat mainly using text, but both the user and the advisor may also use the QA service mainly using a voice chat while using the speakers 370 and the microphones 380 of the communication terminals 300 and 200.
Some or all of the roles of each of the devices of the network system 1 in the above-described embodiments may be performed by other devices. For example, some or all of the roles of each of the server 100 and the communication terminal 300 may be performed by other devices, or some or all of each of the roles of the devices may be divided and performed by a plurality of devices. For example, some of the roles of the application program of the communication terminals 300 and 200 may be performed by the server 100, or some or all of the roles of the server 100 may be performed by the communication terminals 300 and 200.
Specifically, the CPU 310 of the communication terminal 300 may determine whether the prescribed condition has been satisfied on the basis of a program for the user stored in the memory 320, or HTML data. Then, when exchanges of questions and answers with the chatbot have been repeated three times or more, in accordance with the program, the CPU 310 may cause the touch panel 350 to display the button for starting the live human chat.
In the embodiments described above, a network system is provided that includes a first terminal used by a user, a second terminal used by an advisor, and a server configured to automatically conduct a chat with the user, using a chatbot, and in a case where a prescribed condition is satisfied, cause at least one advisor to take over the chat with the user.
