FIG. 12 is a diagram showing a flow of response mail transmission processing.
The automatic response device 20 extracts an action keyword from the sentence (S441), and if an action keyword can be extracted (S442: YES), an action corresponding to the extracted action keyword (hereinafter referred to as an inquiry action) is an action keyword. It is specified from the database 253 (S443). The automatic response device 20 reads the automatic response flag corresponding to the identified inquiry behavior from the behavior keyword database 253, and if the automatic response flag is “x” (S444: NO), the process is terminated.
When the automatic response flag is “◯” (S444: YES), the automatic response device 20 performs the specified date and specified time calculation process shown in FIG. 13 (S445).

  The automatic response device 20 acquires the current date and time (S461), extracts the date keyword included in the sentence (S462), and when the date keyword could not be extracted (S463: NO), The designated date is set (S464). On the other hand, when the date keyword can be extracted (S463: YES), the automatic response device 20 reads the added value corresponding to the extracted date keyword from the date keyword database 254 (S465), and sets the number of days of the read added value. The date added to the current date is set as the designated date (S466).

  Next, the automatic response device 20 extracts time information from the sentence (S467), and when time information can be extracted (S468: YES), the time indicated by the time information is set as the designated time (S469). On the other hand, when the time information cannot be extracted from the sentence (S468: NO), the automatic response device 20 does not have the designated time (S470).

  When the specified date and the specified time are obtained as described above, the automatic response device 20 reads the action time and the required time corresponding to the inquiry action from the action keyword database 253 and is registered in the schedule database 255. Of the schedule information, the schedule time end time is during the action time and the time until the start time of the next schedule information is longer than the required time (hereinafter referred to as final schedule information) is read (S446). The automatic response device 20 creates a response mail (S447), and returns the created response mail to the mail transmission terminal 10 (S448).

FIG. 14 shows the flow of response mail creation processing.
The automatic response device 20 first creates a response mail including a predetermined fixed message (S481). When there is a designated time (S482: YES), the automatic response apparatus 20 determines whether there is any one that includes the designated time from the start time to the end time of the scheduled time (the designated date and time). Whether there is schedule information) is searched, and the search result is added to the response mail (S483).

  Further, when there is schedule information of the designated date and time (S484: YES), the automatic response device 20 reads out an inconvenient message corresponding to the inquiry action from the message database 256 as a response message (S485). (S484: NO), a convenient message corresponding to the inquiry behavior is read from the message database 256 and used as a response message (S486).

  The automatic response device 20 rewrites the character string “% action%” included in the response message to the action of the final schedule information (S487), and sets “% time%” included in the response message to the final schedule information. Is rewritten at the end time (S488), and the response message subjected to the above rewriting is added to the response mail (S489).

Furthermore, the automatic response device 20 determines whether schedule information corresponding to the current date and time is registered in the schedule database 255 (S490). When the schedule information of the current date and time is registered (S490: YES), the automatic response device 20 refers to the schedule database 255 to identify the vacant time (S491), and a message to reply to the identified vacant time Is added to the response mail (S492).
As described above, a response mail corresponding to the keyword included in the inquiry mail is returned to the mail transmission terminal 10.

FIGS. 15 and 16 are diagrams for explaining a specific example of processing for creating a response mail 600 in response to the inquiry mail 500.
In the example of FIG. 15, when an inquiry mail 500 including one sentence “Would you like to drink a cup at around 20:00 today?” Is received, syntax analysis is performed in (S421) of FIG. The action keyword 501 “drink” is extracted in (S441) in FIG. 12, and “drinking” is specified as the inquiry action in (S443) (512).

  Next, when the date keyword 502 “today” is extracted in (S462) in FIG. 13 and the date at the time of processing is April 1 from the corresponding addition value “± 0”, April 1 is designated as the designated date (513). In (S467), time information 503 “20:00” is extracted, and “20:00” is obtained as the designated time (514).

  In response to the inquiry mail 500, a response mail 600 as shown in FIG. 16 is created. First, in (S481) of FIG. 14 above, a response mail 600 including a standard message “This is an automatic response.” Is created, and schedule information corresponding to “20:00” as the designated time is not registered. In (S483), a message 610 "There is no schedule for 20:00" is added to the response mail 600.

  When the schedule information corresponding to the designated date and time “April 1st 20:00” is not registered, “% action% ends at% time%”, which is a convenient message corresponding to “drinking” of the inquiry action So let's do it all! "(621) is read from the message database 256, and in (S487) and (S488),"% action% "and"% time% "are the actions of the final schedule information, respectively. It is rewritten to “work” and the end time “19:00” of the final schedule information (622) and added to the response mail 600. Further, when schedule information corresponding to the current time is registered, a message 630 indicating that a reply is made to “17:00”, which is a free time, is added to the response mail 600 in (S492).

  As described above, the automatic response device 20 extracts the action keyword from the inquiry mail to the user transmitted from the mail transmission terminal 10, and returns a response message corresponding to the action keyword. Therefore, even if the inquiry mail is described in a free format, a flexible response according to the contents can be automatically returned. Therefore, the sender who sent the inquiry mail can quickly receive what kind of response is likely to be made to the inquiry contents, even in a situation where the inquiry destination user cannot respond immediately. .

  In addition, the automatic response device 20 of the present embodiment adds a free time not registered in the schedule to the response mail when there is already registered schedule information when the inquiry mail is received. The sender can know when the user can receive a reply directly.

  In addition, a response email is returned only when an action keyword is included in a sentence that has been determined to be a solicitation sentence or a question sentence by syntax analysis, so that a response is not made in response to a sentence other than a query. Can do.

  A free message can be set in the response message registered in the message database 256. Therefore, the automatic response device 20 can send back a response message reflecting the user's preference. For example, for actions that the user does not care about, it is possible to register a negative message as a convenient message so that a negative response is made even if the schedule is not available.

  In addition, the automatic response device 20 according to the present embodiment notifies that an emergency is indicated by display on a display or output from a speaker when an inquiry keyword includes an emergency keyword indicating that an emergency is required. Can do. Therefore, the user can quickly respond to an urgent inquiry.

  In the present embodiment, the date keyword and time information are extracted for each sentence obtained by dividing the inquiry mail by the syntax analysis, but may be extracted from the entire inquiry mail. Thereby, it is possible to cope with a case where the action keyword and the date / time information are not included in the same sentence.

  In this embodiment, the response message is prepared for each action, but a message corresponding to the action or the mail address of the transmission source may be registered.

  Further, the automatic response device 20 may include a transmission history database that stores response mails returned to the mail transmission terminal 10. In this case, the user of the automatic answering device 20 can confirm the automatically answered mail later.

  Further, in the present embodiment, for the sake of simplicity, the exchange of e-mail between the mail transmission terminal 10 and the automatic response device 20 is performed directly. However, for example, the exchange is performed via a mail server. Also good.

  Further, when electronic mail is exchanged via the mail server as described above, the mail server may perform processing for creating and transmitting a response mail.
