Then, the message content of the user 120b is transmitted from the chat server 141 to all the users including the user 110a (4).

On the other hand, when the user 110a is not connected to the chat system, all of the other user's remarks on the chat channel of the preset chat server are transmitted to the chat server 141 (5), and the chat server 141 sends the user 110a To the agent 150a. Then, the agent 150a records and stores the statement history in the statement history storage unit 151a (6).

Next, the flow from requesting and acquiring the desired message history by the user 110a will be described. Here, the user 110a uses the telephone 310 as the statement history output requesting section 180, and the FAX as the statement history output section 190.
An example will be described in which the statement history is output using the command 330.
First, the user 110a uses the telephone 310 to access the user authentication history processing unit 170 via the public line 300 and the exchange 160 (7), so that the message history management system in the present chat system is activated and the user authentication history The processing unit 170 requests the user 110a to input a user name and a password (8).

The user 110a inputs a user name and a password according to the request (9). Here, it is assumed that the user name and the password are composed of a combination of numbers, characters, and symbols that can be input on a telephone or the like, and are registered in the user authentication history processing unit 170 in advance. The user authentication history processing section 170 searches whether or not the combination of the input user name and password is already registered. As a result of the search, if the combination of the input user name and password is not registered, for example,
It is announced that the user cannot be authenticated by a voice saying "Authentication is not possible from the entered user name and password."

On the other hand, if the combination of the entered user name and password is registered,
The authentication of a is established. Then, the user authentication history processing unit 1
70 requests the user 110a to input various output conditions of the statement history as described later (10). User 1
In accordance with various requests from the user authentication history processing section 170, the user 10a inputs the output condition of the statement history as described later (11).

Here, the output condition of the comment history is FAX3
This is a condition relating to a method of displaying the comment history output from the message history 30. Depending on the setting of the output condition, the desired character of the user 110a may be displayed, such as displaying the uttered character of the specific speaker in a large size, changing the color, or displaying only the content of the utterance of the chat performed in the specific time zone. It is possible to output a statement history.

Transmission and reception of information in steps (10) and (11) are performed as follows. First, a request for the first output condition input by the user authentication history processing unit 170 is, for example, “Please select an output method.“ 1 ”is output when outputting by voice, and“ 2 ”when outputting by facsimile.
Press "3" to send by e-mail or "0" to cancel. ".

The user 110a selects a desired output method (for example, FAX) and inputs a selection number "2" corresponding to the output method. Here, if the user 110a desires to output a statement history by facsimile, the user authentication history processing unit 170 inputs the facsimile number to the user 110a.
Request to. When the user 110a desires to output a statement history by e-mail, the user authentication history processing unit 170 inputs the e-mail address to the user 11a.
0a.

The user 110a receives the above request from the user authentication history processing section 170 and inputs a FAX number. When the output method is specified, the user authentication history processing unit 1
70 requests the user 110a to enter the name of the chat server to which the message history to be output belongs. This request
For example, "Please select the name of the chat server to which the message history to be output belongs. If you want to output the message history of chat server A, enter" 1 ". If you want to output the message history of chat server B, enter" 2. " To cancel, please press "3". "

The user 110a selects a desired chat server, and inputs a selection number corresponding to the chat server. When the chat server is selected, the user authentication history processing unit 170 requests the user 110a to input a channel name to which the output history belongs. This request may be, for example, "Please select the name of the channel to which the history of the message to be output belongs. If you want to output the history of the speech of channel # 1, enter" 1 ". Press "3" to output the comment history of channel # 3, and press "0" to cancel. "

The user 110a selects a desired channel and inputs a selection number corresponding to that channel. When a channel is selected, the user authentication history processing unit 170 requests the user 110a to select whether or not to specify the date of the utterance history to be output.
This request is made, for example, by a voice such as "Press" 1 "to specify the date of the utterance history to be output, and press" 0 "otherwise."

When "1" is input by the user 110a, the user authentication history processing section 170
10a is requested to input a date to output the comment history. On the other hand, when “0” is input, for example, the statement history on the day on which the statement history output request is made is output. When the date of the message history to be output is designated, the user authentication history processing unit 1
70 requests the user 110a to select whether or not to specify the time at which the utterance history to be output is uttered. This request is made, for example, by a voice such as "Press" 1 "to specify the time zone of the utterance history to be output, and press" 0 "otherwise."

If "1" is input by the user 110a, the user authentication history processing section 170
10a is requested to input the time zone of the speech history to be output. On the other hand, when “0” is input, for example, all the comment histories on the day on which the comment history output request is made are output.
It is assumed that the user can arbitrarily set a date and a time zone for which the comment history is output when “0” is input.

When the time period of the utterance history to be output is designated, the user authentication history processing unit 170 requests the user 110a to select whether or not to output only the utterance history of a specific speaker. . This request is, for example, “1” when the utterance history is output by specifying the speaker (nickname) of the utterance history to be output, and “2” when the utterance history is not specified.
Please press ".

When "1" is input by the user 110a, the user authentication history processing section 170
10a is requested to input a speaker name. Here, the speaker name is composed of a combination of numbers, characters, and symbols that can be input using a telephone or the like.
0 is registered. The above steps (1
After the output conditions desired by the user 110a have been set through (0) and (11), the user authentication history processing unit 170 requests the agent 150a for the speech history desired by the user 110a (12). And Agent 1
In response to this request, 50a retrieves the statement history corresponding to the request from the statement history storage section 151a and transmits it to the user authentication history processing section 170 (13). The user authentication history processing unit 170 processes the comment history based on the output condition designated by the user 110a, and faxes the comment history information.
It is transmitted to 330 (14). Then, the message history desired by the user is output from the FAX which is the desired output form.

Here, the method of setting the output conditions in steps (10) and (11) and the contents of the output conditions can be variously set or can be changed as appropriate according to the usage environment of the statement history management system. For example, in addition to the above example, it is possible to color-code the utterance for each utterer, distinguish fonts, specify a keyword, and output all utterances including the keyword.

FIGS. 6 to 12 show examples of speech histories output on a facsimile or a display screen of a computer. In the output examples of FIGS. 6 to 12, it can be seen that the utterance time 400, the utterer (nickname) 500, and the utterance content 600 are processed into various forms and output according to the output conditions set by the user. Figure 6 shows the speaker (nickname)
This is an example in which the statement history is output with different colors for each. The shaded, bold, and italic character strings in FIG. 6 each have a different color from the other character strings.

Since the utterance history is output by changing the color for each utterer (nickname), the utterance content of each utterer can be easily grasped. FIG. 7 is an example of a statement history output in which the font (font, size) is changed for each speaker (nickname) and output. Since the font is changed for each speaker (nickname), it is easy to understand who made each statement, and it is easy to grasp the statement of a specific speaker.

FIG. 8 is an example of a statement history when the output condition is to output a statement including a specific character string "X". In FIG. 8, the user authentication history processing unit 170 outputs a comment including the designated character string “X” and a comment 10 times before and after the comment. By outputting an utterance including a specific character string and utterances before and after the utterance, the user can easily grasp the content, flow, and atmosphere of the chat relating to the specific character string as a keyword. By setting in advance, the number of utterances displayed before and after the utterance including the designated character string can be arbitrarily changed.

FIG. 9 is an example of a statement history output when the output condition is to output all the statements including the specific character string "X". By outputting all the utterances including the specific character string, it is possible to easily grasp only the utterance related to the specific character string. FIG. 10 shows that the user 110a specifies the time zone “from 9:00 to 13
This is an example in which “15 minutes” is performed and all the contents uttered during the designated time zone are displayed.

By displaying all the comments made during a specific time period, the user 110a can later grasp the content of the comments made during the time period in which it was unavoidable to participate in the chat, for example. . FIG.
FIG. 9A shows an example in which a channel designation of “# 1” is designated, and a statement history of the contents stated in the designated channel “# 1” is displayed.

By displaying the utterance made on a specific channel, the user 110a can grasp the utterance history of the chat made on the desired channel. FIG. 12 shows an example in which the user 110a designates a speaker (nickname) “AAA” and displays all the statements made by the designated speaker (nickname) “AAA”.

By designating the speaker (nickname), the user 110a can easily grasp only the speech of the specific speaker. In the above embodiment, the agent 150a corresponds to a statement history acquisition unit and a statement history output control unit, and the statement history storage unit 151a corresponds to a statement history storage unit. The user authentication history processing unit 17
0 corresponds to a user authentication unit, a statement history processing unit, a search condition setting unit, a statement history search unit, and an output condition setting unit.
