DETAILED DESCRIPTION OF THE INVENTION

Next, embodiments of the present invention will be described in detail. [First Embodiment] FIG. 1 shows the configuration of a mail system according to an embodiment of the present invention. The mail system according to this embodiment includes a mail creating terminal 11 and a mail server 1.
2, a hard disk 13, and this mail system is connected to other mail servers 22, 23, 24, etc. via a network 14 such as an in-house LAN.
The mail input terminal 11 is equipped with a keyboard and a mouse 11m for inputting a mail, and a mail creation program for creating a mail is installed. By starting this, a mail is created. be able to.

An example of the mail creation screen is shown in FIG. In the "destination" column m1, a specific email address, a destination name (department name, mailing list name, etc.),
Alternatively, a keyword can be input. In the present embodiment, when inputting a keyword, the keyword (eg "stock""Asecurities") is enclosed in parentheses as shown in FIG. 1B in order to distinguish it from the destination name. And When entering multiple keywords under the AND condition, symbols such as "&" and "AND" are entered between the keywords, and when entering under the OR condition, "|""O" is entered between the keywords.
Insert a symbol such as "R". In addition to this, a NOT condition or the like may be designated.

The "CC" column m2 is a portion for entering the mail address of the other party to whom a copy of the mail is to be sent as a reference material. In addition, a title indicating the content of the text is described in the “subject” column m3. The body of the email is described in the column m4 below it.

The mail server 12 is a mail input terminal 11
The server has a function of determining the destination of the mail transmitted from the computer and transmitting the mail, and delivering the mail received from the outside to the mail input terminal 11.

As shown in FIG. 2, the hard disk 13 stores a group name such as a department name (eg, general affairs department), a mailing list name, etc. together with the mail addresses of its members. Further, each group name is added with various keywords that represent its characteristic. For example, for a department named “General Affairs Department”, along with the member's email address (sm1@xxx.co.jp, sm2@xxx.co.jp ...), the characteristics of the department name (field of responsibility, specialty) Keywords (personnel, employment, insurance), etc. indicating fields etc. are stored.

For the mailing list "A Securities Association", the member's mail address (a1@xxx.co.
jp, a2@xxx.co.jp ...), the keywords (stock, A securities company) expressing the characteristics of the mailing list are stored. Also, among the members of "A Securities Association", the owner an of the email address an1@xxx.co.jp may want to receive emails regarding A securities, but not emails regarding stocks. obtain. In this case, the owner an receives information (hereinafter referred to as “rejection information”) that he / she does not want to receive a mail regarding stocks, and the rejection information is stored in the hard disk 13. This makes it possible to prevent the mail M from being sent to the owner an when the mail M having “stock” as a keyword but not including “A securities” as a keyword is sent.

Specifically, the mail address an1@xxx.co.jp of the owner an is excluded from the mail address list of the "Securities Association of A" to which the owner an belongs, and at the bottom of the table in FIG. As shown in, a new mailing list name of "A Securities Association (excluding stocks)" is added to the mail address an1@xxx.co.jp and stored. This new mailing list name constitutes the above refusal information. As the corresponding keyword, “A securities company not stock” is stored. As a result, only an email with the keyword "A securities company" is sent to the owner an,
E-mail with "share" as a keyword will not be sent. The method of configuring the refusal information is not limited to this, and various changes can be made according to the purpose.

FIG. 3 is a functional block diagram showing the contents of various processes relating to the mail from the mail input terminal 11 in the mail server 12, which is realized by a computer program stored in a storage medium (not shown) in the mail server 12. To be done. That is, the mail server 12 includes the mail receiving unit 12a, the destination determining unit 12b, the match detecting unit 12c, the address reading unit 12d, and the address assigning unit 1.
2e and a mail transmission unit 12f.

The mail receiving section 12a is a mail input terminal 1
It has a function of receiving the mail M sent from the server 1 and temporarily holding it. The destination determination unit 12b uses the destination field m1 of the mail M.
It has a function to judge the description content of. Match detection unit 12c
Has a function of detecting a match between the contents of the destination field m1 and the contents of the hard disk 13. The address reading unit 12d has a function of reading the mail address when a match is found by the match detecting unit 12c. Further, the address assigning unit 12e sends the mail address read by the address reading unit 12d to the mail M.
It has a function to add to. The mail sending unit 12f has a function of sending the mail M, to which the mail address is given, to the outside by some method.

The operation of the mail server 12 will be described below with reference to the flow chart shown in FIG. When the mail M is received by the mail receiving unit 12a (S1), first, the destination determination unit 12b determines whether the content described in the destination field m1 of the mail M is a specific email address or the name of the destination (department name,
Mailing list name, etc.) or a keyword (S2, S3, S4). In the present embodiment, whether the description in the destination field m1 is the name of the destination or the keyword is determined by whether or not the entered characters are enclosed in parentheses, but by another method. It goes without saying that you can make a decision.

When it is determined that the mail address is a specific mail address, the mail M is directly output to the mail sending section 12f (S5). When the description content is not an address but a group name (department name, mailing list name, etc.), the match detection unit 12c searches the database in the hard disk 13 for the department name, mailing list name, etc. corresponding to the group name. (S6). When a match is found, the address assigning unit 12e determines the mail address of the group name as the destination field m of the mail M.
2 and outputs it to the mail transmission unit 12f (S7).
If there is no match, the mail input terminal 1 to that effect
Reply to 1 (S8).

When it is determined that the description in the destination field m1 is a keyword, a signal indicating the content of the determination is transmitted to the coincidence detection unit 12c. In this case, the match detection unit 12c
Displays the group name registered by this keyword on the hard disk 1 based on the stored contents of the mail receiving unit 12a.
Search in 3. When it is searched, the mail address information of the member of the group is transmitted to the address assigning unit 12e.

The address assigning unit 12e assigns the retrieved mail address to the mail M. At this time,
When a plurality of groups are searched, there may be members registered in both of the plurality of groups, and as a result, a plurality of mails having the same content will reach the member. In order to prevent this, as shown in FIG. 5, when there are a plurality of retrieved group names (S7-1), the address assigning unit 12e causes all of the email addresses belonging to the retrieved plurality of groups. Is acquired (S7-2), and it is confirmed whether or not there is a duplicate mail address (S7-3). If duplicated addresses are confirmed, only one mail address is left and the rest are deleted (S7-4), and only the remaining mail address is given to the mail M (S7-5). If it is determined in S7-3 that there is no duplicate mail address, all the mail addresses acquired in S7-2 are added to the mail M (S7-6). This reduces unnecessary time and mental burden on the recipient. The information of the duplicated mail addresses may be acquired in advance before a plurality of group names are designated by the designation of the keyword. This eliminates the need to search every time a keyword is specified.

[Second Embodiment] Next, a second embodiment of the present invention will be described.
The embodiment will be described with reference to FIG. 6 and the like. In the first embodiment, when the destination of the mail is not specifically known, the keyword is entered in the destination field m1 to automatically select the destination. On the other hand, in the present embodiment, the visualization map Ma as shown in FIG. 6 is displayed on the display of the mail input terminal 11 and the destination of the mail is selected based on this. The contents of the visualization map Ma will be described below.

The visualization map Ma, as shown in FIG.
A field display mark fm showing a field and a name display nm showing a person's name are arranged on a two-dimensional plane. The name display nm is a field display mark n that indicates a field in which the person with that name is interested or is familiar with.
It is displayed near m. For example, the visualization map M in FIG.
In a1, the name display "Karazawa" is displayed near the field display mark "Bankruptcy", which indicates that a person named Karasawa is familiar with or interested in bankruptcy. The distance between the field display mark fm and the name display nm can be changed depending on the degree of interest of the person having the name display in the field, the depth of knowledge, and the like. Name display nm
May display only key persons in the field (department manager, development team leader, etc.), and the other person's name display nm may be hidden.

A plurality of visualization maps can be prepared for each field. For example, as shown in FIG. 6, fields related to “law / economy” and “computer / communication”
Different maps Ma1 and Ma2 can be prepared for fields related to. Of course, when the types of fields are limited, all the field display marks fm may be arranged in one map.

Further, as shown in FIG. 6, even in one visualization map Ma, the field display marks fm having similar contents to each other are arranged at a distance closer than the field display marks fm far from each other in terms of content. . For example, as shown in FIG.
In the map "Ma1" of "economy", the field display marks "patent" and "copyright", which are similar contents, are arranged at a closer distance than "stock" or "bankruptcy" which are far from the contents.
Further, even if the fields are different, if the range of persons who are familiar with the field is common, the field display marks fm may be close to each other. In addition, by displaying the name display nm of a person who is familiar with the field and the name display nm of a person who is just interested in different colors (eg, the former is red, the latter is blue, etc.), etc. You may be able to distinguish.

Incidentally, in such mapping of the mark fm, the system administrator may manually arrange the marks on the map, but may also be automated by using a known self-organizing map or spring model. it can. References to introduce these are "Self-organizing map" (T. Kohonen, Springer Veillark Tokyo, 1996), "Construction of idea inspiration system using spring model" (7th AI Symposium (S
IG-J), December 1996) and the like. Further, on the right side of each of the maps Ma1 and Ma2, an adjustment volume B (B1, B2) for changing the range selected as the mail transmission destination is provided.

Next, a method of selecting the destination to which the mail M is sent by using the visualization map Ma will be described with reference to FIG. Here, it is assumed that a mail is sent to obtain information about M & A. First, the visualization map Ma1 regarding “law / economy” is selected. After that, the field display mark “M & A” is selected. The selection can be performed by moving the pointer P displayed on the display with the mouse 11m of the mail input terminal 11 and clicking the button of the mouse 11m.

When the field display mark fm is selected, FIG.
As shown in, the field display mark fm (“M & A”) is changed from the thin line display to the thick line display, and the circle display C1 shown by the dotted line is displayed. This circle display C1 is the circle C1
It means that the name display nm included in is selected as the destination of the mail M. In the example of FIG. 7, “Okigawa” and “Koizumi” are selected as the destinations of the mail M.

The size of the circle display C1 that is first displayed when the field display mark fm is clicked with the mouse 11m is
It is determined by the position of the adjustment gauge Bg in the adjustment volume B1 described above. When the adjustment gauge Bg is at the highest position, the size of the circle display C1 is maximum, and when the adjustment gauge Bg is at the lowest position, the size of the circle display C1 is the minimum. That is, by adjusting the adjustment volume B1, it is possible to set the range in which the mail is to be sent. In real world conversations,
Speak loudly if you want many people to talk to you, or in a place where many people can hear you (for example, on the stage), while you want to talk to only a few people Speak in a small voice or talk in an empty area. The adjustment volume B realizes the adjustment performed in the real world on the mail system.

The volume B1 may be adjusted before clicking the field display mark fm to be selected,
It may be done after clicking. The size of the circle display C1 may be adjusted so that the circle display C1 itself is dragged and dropped with the mouse 11m.

When the size of the circle display C1 is determined, the "OK" icon displayed at the lower right of the map Ma1 is clicked with the mouse 11m. As a result, the mail address related to the name display nm included in the circle display C1 is the mail M
Is added to the destination field m1. A conventional CAD tool or the like is used as a method of designating the area on the visualization map. Needless to say, various methods used in conventional CAD tools and the like can be applied as the method of specifying the area on the visualization map. For example, FIG. 7 (b)
As shown in FIG. 7, a method of designating an end point with a mouse and setting a name surrounded by a rectangle R1 as a destination, as shown in FIG. 7C,
There is a method of drawing a free curve FR1 with a mouse to enclose the area and designating the inside of the area as a destination.

[Modification] The embodiments have been described above, but the present invention is not limited to these.
For example, the following changes are possible. (1) In the above-described embodiment, all the retrieved groups are targeted for the e-mail address assignment to the e-mail M. However, as shown in FIG. And send to the mail input terminal 11
A list of the group names is displayed on the display (S21). The mail sender looks at this list and selects the name of the group that needs to be sent (S22). This selection can be performed by, for example, the mouse 11m. Then, the mail address related to the selected group name is added to the destination field m1 of the mail M and output to the mail transmission unit 12f. This makes it possible to avoid transmission to a destination that does not need to be transmitted.

(2) Further, the keyword described in the destination field m1 can be described in the header H1 of the mail M (FIG. 9). As a result, the recipient of the email can confirm the sender of the received email at a glance.

(3) In the second embodiment, both the field display mark fm and the name display nm are displayed on the visualization map M, but only the name display nm is displayed and the name display nm itself is displayed. The name display nm arranged around the mouse 11m may be selected as the transmission destination mail address depending on the adjustment of the adjustment volume B. Needless to say, various changes and additions can be made without departing from the spirit of the present invention.
